This update improves speech, editing accuracy and the reliability of longer projects. • Supertonic speech has clearer pronunciation and emphasis, with fewer omitted words. Interrupted downloads of the shared VoxCPM2 Turkish voice package can recover more reliably. • Projects now show the correct media type after converting between audio and video. Long audio-to-video conversions, including two-hour recordings, retain their full duration. • Exporting a photo project lasting an hour is more reliable, with the image retained through the end. • Time selection in Face Censor and effects is more consistent. Magic Trim supports precise adjustments to hundredths of a second. • VoiceOver focus is more stable when adjusting audio fade durations. Undo and redo controls also take up less space. • Five animal and insect sounds have been improved for a more natural result. • Clearer explanations show why subtitles or audio separation may be unavailable for a project. • Merging 4K and variable-frame-rate clips, trimming and changing speed better preserve smooth motion and audio sync, together with HDR colors and video orientation. • Audio descriptions use more precise timing, and incorrect warnings that a description extends beyond the project have been corrected. • In Audio Description, you can review and confirm adjustments before importing an SRT or VTT file that extends beyond the video. After confirmation, entries starting at or after the video end are skipped; for entries crossing the end, only the end time is set to the video end. The text of retained entries and the original SRT/VTT file remain unchanged.

Bug fixes

• Improved VoxCPM2 voice model download progress, resuming interrupted downloads, and error messages. • Fixed recognition of saved MP3 projects to prevent unnecessary video-to-audio conversion prompts. • The Remove Burned-In Subtitles shortcut is now next to Subtitles, matching the other toolbar buttons. • Improved file safety when saving projects.

• Added 7 VoxCPM2 Turkish voices to the Premium voice library, with improvements to samples, speech generation and playback. Built-in samples play without downloading the large voice model. • Remove Burned-In Subtitles: choose detected text and a time range, or add regions with accessible controls. After an optional download of about 40 MB, processing is offline. Compare before and after, keep the video’s audio, and undo changes. Detailed scenes may retain artifacts, and processing may take longer than the video. • Premium > Downloaded Models shows package names and storage use, so you can delete packages or download them again. • Insert Audio can now use saved audio projects and, with your confirmation, convert video projects to audio. Fixed a file-handling issue affecting MP3 sharing on iPhone.

With this update, you can create music with artificial intelligence. Discover this feature now in Extra Tools. Free, unlimited AI-generated music... We have also fixed many bugs identified through our testing and feedback from you, our valued users.

• New Face Censoring tool: cover all detected faces or selected face segments with blur, mosaic, or a black mask. • Choose Apple Vision, open-source MediaPipe, or both for on-device face detection. Add manual masks, adjust their movement and timing, and preview the result before applying it. • Improved duration, start, and end fields at large text sizes. Removed empty buttons from Sepia and Pixelate, and corrected Premium code translations. Face censoring cannot guarantee complete coverage. Before sharing, we recommend having a sighted person visually check the entire video.

VERSION 5.1 WHAT'S NEW • AI upscaling: sharpens and enlarges videos with an AI model that runs entirely on your device. • AI frame rate boost: creates in-between frames for smoother motion, with 90 and 120 fps options. • Stem separation: splits audio or a video's sound into vocals, drums, bass and other sounds; set each level and mix them back together. • Framing Assistant: gives spoken guidance with the camera about face position, distance, lighting and sharpness, and can also check the framing of the open video. • Face-Tracking Vertical Framing: turns landscape video into 9:16, 4:5 or 1:1 by following the face, with a blurred-background option. • Offline subtitles with Whisper: choose Apple or Whisper in automatic and translated subtitles. The model is built into the app, so there is no extra download. • Real MP3 export at 192 kbps for audio and video projects. • DeepFilterNet3 noise reduction is now the default, with adjustable strength, mix and before/after listening. • Accessible timeline: arrange clips in order and add independent music and text layers. • Portable projects: export and import projects, and receive media sent from other apps. • New photo start: pick a photo from Create New, then set its duration and effects. • My Projects: each project is a single VoiceOver item, with rename, export and delete in the Actions rotor. FIXES • Timeline edits no longer drop 60 fps footage to 30 fps; each clip keeps its own frame rate. • 90 and 120 fps exports keep their rate. Photos may treat files above 60 fps as slow motion, so a warning appears when that cannot be avoided. • A project that failed to load could open with the previous file and overwrite the new project when saved. Fixed. • AI tools check free storage before starting, and their errors now appear on the tool screen. • Frame rate boost no longer fails on videos with odd dimensions or faulty frame timing. • Buttons that need video are dimmed in audio projects, and sound tools are dimmed on silent videos, with the reason read aloud. • Opening files from other apps no longer moves or deletes the original. • A slideshow with missing sources could delete the old asset folder. Fixed.

zEdit 5.0 is here. One of our biggest updates yet! The timeline lets you edit your projects in greater detail. Mono and stereo audio controls have been added.

VERSION 3.8 WHAT'S NEW • Entrance effects for the image overlay. Twenty effects are available: slide from left and right, drop, rise, zoom in, zoom out, spin, horizontal and vertical unfold, curtain, blinds, mosaic, rain, sweep, diagonal, ripple, zipper, pop and fade. With no effect selected, behaviour matches previous versions. • Intensity control for audio filters. The strength of each filter can be adjusted and samples are generated at the selected intensity. A filter already in the list can be edited afterwards, updating both its time range and its intensity. • The hook title is processed as soon as it is added. The operation is compatible with undo and redo and can be cancelled while running; on cancellation the media is left unchanged. FIXES • Pitch-shifting audio filters did not preserve duration. Helium, giant and deep robot played back faster and the end of the section was inaudible. Pitch shifting was rewritten using time stretching, so duration and speed are preserved. Helium additionally received a speech-band boost and a reduced shift; filter character is retained while speech remains intelligible. • Added a safeguard against the export becoming unresponsive. If progress does not change for an extended period, the operation is stopped with a clear error, and export can now be cancelled. On high frame rate sources the overlay pass is fixed at 60 frames per second; duration and speed are unaffected. • Duration selection in the visual effects menu now uses hour, minute and second fields, with a hundredths field when the milliseconds setting is enabled. The previous half-second stepper has been removed.

VERSION 3.7 WHAT'S NEW • Image overlay on video. An image selected from the photo library or Files is displayed over a defined time range or for the whole video. Aspect ratio is preserved and portrait images are letterboxed; the image is never rotated or stretched. Compatible with saved projects and undo. • Automatic work protection. The editing session is written to a recovery record in the background. If the app closes unexpectedly, resuming the session is offered at the next launch. Recovered work is also listed under My Projects, where its size can be reviewed and the record opened or deleted. A single record is kept, overwritten in place, and cleared automatically after one week. • Expanded insert flow. Content can be taken from the photo library or from Files, and photos can now be inserted alongside video and audio. Display duration is set for photos. • Audio filter samples are now generated from the source media. A ten-second section from a random position is played with the selected filter. Shorter media is used in full. • Filter processing starts on add. In earlier versions processing did not begin until the menu was dismissed. • The AI section in Settings has been reorganised. Providers are consolidated into single cards with connection status shown directly; authentication, model and verification appear under separate headings. Descriptions have been simplified. FIXES • Fixed a crash when inserting silence with low sample rate audio sources. Output settings are now derived within a valid range for the source, and an compatible configuration is applied automatically when settings are rejected. • Fixed the hook title not appearing in the video, leaving a black area in its place. • Fixed subtitles rendering their background band without the text. • Fixed a timing fault that displayed subtitles and the watermark over a random section instead of the selected range. • Audio filters have been retuned to preserve speech intelligibility. Filter character is retained while spoken content remains distinguishable. • Fixed sample playback continuing after the page was closed. • Removed the inconsistent title and duplicate description from the Add Content menu. • The minutes field is now shown in all time pickers. With the milliseconds setting enabled, time values are presented to hundredth-second precision on screen and through the screen reader. • Fixed incorrect rendering of the photo duration text in seven languages. • Reduced the likelihood of the app being terminated during long operations. The screen no longer locks automatically while processing, and per-frame memory use during export has been reduced.

VERSION 3.6 WHAT IS NEW • Export quality is now yours to choose in Settings. Compatibility plays on any device, Balanced is the default, and Highest keeps your recording's codec for a visibly better image at the same file size. • You now choose how the picture sits when resizing. After picking a ratio, Fit keeps the whole image, while Fill removes the black bars completely — turning a landscape video into a portrait one crops a little from the sides. FIXES • The "operation could not be completed" error when opening a video from the photo library is fixed. Importing now works in three stages, and every stage verifies that the file really opens. • Videos shot with the back camera of some iPhone models no longer fail to open. The file is now saved with the extension its container actually calls for. • Exported videos no longer show up as slow motion in the gallery. Only frame rates above 60 are brought down to 60; videos shot at 30 or 60 are left untouched, and duration and speed are preserved exactly. • The Add Audio page in the editor no longer opens blank. • Image quality on export is noticeably better. High frame rate videos are no longer encoded at half the bit rate, the visual effects step no longer drops audio to a single channel, and the audio sample rate now matches the source. • Watermark, subtitles and hook title are burned in a single pass. One encode instead of three: better quality and a noticeably faster export.

VERSION 3.5 WHAT IS NEW • AI support. Enter your Gemini, OpenAI, Grok or Claude API key in the new Artificial Intelligence section of Settings. The key is stored only in your device secure keychain; requests go straight from your own account, the app is not in between and charges nothing. For each provider you can pick a model, refresh the model list from the provider, and test the connection with one tap. • AI Description. In the editor, frames are taken from the range you choose and the AI writes timed descriptions for blind viewers. You set the density and the style. Read the texts and send the one you like to the Audio Description tool with one tap. • Ask the AI. Ask anything about the part of the video you choose. Video frames and the spoken text, if any, are sent together, so both visual and audible questions are answered. • You can select more than one AI. Each model answer appears in its own section, so nothing is lost inside another answer and you can compare models. • Automatic subtitles can now be produced by AI. On-device recognition is free but makes mistakes; with a key, subtitles are produced with your own subscription and are noticeably more accurate. You choose the method each time. • In audio description, the providers natural voices were added to the voice list. They work in exactly the same flow as device voices. FIXES • Error messages are now really shown in the language you selected. A mapping bug made every processing error appear in English no matter which language was chosen. • The rate slider and the sample button, which do nothing for AI voices, are no longer shown for them.

VERSION 3.3 FIXES • Fixed the app quitting unexpectedly on long videos. Processed frames accumulated in memory until the system terminated the app. Memory now stays flat regardless of video length. The same protection was applied to slideshows, photo-to-video, audio processing and all analysis steps. • Fixed speed changes failing after the first attempt, and added an automatic retry if an export is rejected. • Fixed exported videos having width and height swapped on recordings that carry rotation information. • Ducking the video's sound during audio description now works reliably; "mute completely" and zero percent had no effect on some videos. • Precise position control with the rotor now works. NEW • With hundredths shown, "forward/back one hundredth" buttons appear under the time pickers for one-tap fine tuning. • Volume levels in audio description adjust in five-percent steps, with VoiceOver too. • Loop Forever: added audio repeats until your media ends. • Auto-ducking: music is gently lowered during speech. • Enhance Voice: one-tap noise reduction. • More Options: export the selected part as a separate file or turn it into a new project.

VERSION 3.2 The star of this release: projects can now be added to each other. NEW • More Options: in Cut Between Two Points and Magic Trim, the part you selected can now be exported as a separate file or turned into a new project with a unique name — without touching your open media. Exports go through the app's quality- and compatibility-guaranteed shared export path. • Loop Forever: when adding music, a new "Loop Forever" option with a "more info" button next to it. When on, the added audio repeats from the beginning until your media ends — a short piece of music plays until the video finishes. The fade-out lands at the end of your media, and auto-ducking works across all repeats. • Auto-ducking: when adding music, a new "Auto-duck music during speech" option finds the speech in your video with energy analysis and gently lowers the music during it — the classic radio and documentary mixing rule, in one tap. • Enhance Voice: one-tap strong noise reduction. It suppresses outdoor rumble and wind and brings speech forward; the result can be undone. • Precise position control with the rotor: the player's "current position" is now a VoiceOver-adjustable element. Swiping up or down moves the position second by second, with haptic feedback on each step if your vibration setting is on. • "Choose from Projects" comes to Add to Beginning / End. Pick one of your saved projects; every pending edit in it — subtitles, sound effects, audio filters, watermark, visual effects and audio descriptions — is processed automatically, step by step, and the result is added to the beginning or end of your open media. Progress is announced with percentages throughout. The project you picked is never modified; it stays a project. • Type matching is handled intelligently: while editing a video, audio projects (and vice versa) are listed under "Projects of a different type" and require your confirmation. If you confirm, an audio file is added as a black-screen video with its sound; a video is added with its picture removed, audio only. FIXES • Precise position control with the rotor now works: swiping up or down on the player's "current position" element with VoiceOver had no effect. The element is now genuinely adjustable and swiping moves the position second by second. • In audio description, the spoken duration of very long texts is now measured correctly: the measurement's safety limit was a fixed 20 seconds and cut long texts short, making the duration info and its overflow warning wrong. The limit now scales with the length of the text.

VERSION 3.1 A speed and precision update. IMPROVEMENTS • On launch, leftover temporary files from interrupted operations are now cleaned up automatically, so they no longer take up space on your device. • The frozen frame used when inserting silence is now derived from the source's actual frame rate, making it reliable on 24 fps and variable-frame-rate recordings too. • Exports and other long operations are now protected in the background: briefly switching to another app no longer interrupts them. For very long operations that exceed the system limit, the work resumes from where it left off when you return. • Capture date, location and title of processed media are now preserved: exported videos and audio land in your library at their original date instead of today's. • Adding content to the beginning/end is now many times faster: technically compatible videos (same resolution and format) are joined without re-encoding, preserving quality exactly. Content with a different size or orientation still goes through the safe path with correct fitting. FIXES • The "Use current position" buttons now write exactly the second you see on screen; being at second 30 and getting 31 is fixed. Every position button in the app (trim, range trim, insert content, insert silence, audio filters) now follows the same rule. • Fixed being able to pick a time longer than the media in the trim screens: values beyond the end are automatically clamped to the end of the media. • The warning shown before cutting or inserting content now tells the truth: it can be triggered not only by subtitles but also by pending sound effects, audio filters, visual effects or a timed watermark; the text now lists all of them and notes that removed edits can be recovered with Undo. • Prevented possible edge artifacts when a re-encoded video's resolution landed on an odd number.

VERSION 3.0 This release focuses on picture quality and audio control. FIXES • Fixed portrait photos appearing sideways in multi-photo slideshows and in add-music-to-photo: the photo's orientation is now applied. • Fixed the picture turning black after adding audio to a video: during fast processing the video's format information wasn't being carried into the output. Also fixed ordinary wide-gamut videos being mistaken for HDR. • Fixed colors shifting, the picture washing out or distorting in videos with sound effects, filters or added music. Color properties are now preserved exactly from the source, and HDR (Dolby Vision) recordings are correctly detected and processed as HDR. • Fixed Apply and Preview staying dimmed from the start in the trim screens: the end time now defaults to the end of the media, so you can trim as soon as the screen opens. In Magic Trim, marking only the start is enough. • The mute option in the add-audio screen was renamed to say exactly what it does. • Visual effects now appear in the preview too; previously they only showed up in the exported video. • Fixed the permission error when saving projects on iPad. • Fixed the share sheet offering no options for some audio formats. NEW • Insert Content: you can now insert video (not just audio) into the middle of a video. Adding to the beginning/end lives under the same button. • "Use current position" in the trim screens, and the same convenience when inserting silence. • Your selections are kept when returning from the trim preview.

VERSION 2.9 This update focuses on a comprehensive stability review. NEW • The "Insert" feature is now called "Insert Content" and does more: into a video you can insert not only audio but also video (for example a meme) in the middle. Adding to the beginning/end is now an option under the same "Insert Content" button. • A "Use current position" button was added to the trim screens: pick the player's current moment for start and end with one tap. FIXES • Fixed the "you don't have permission" error when saving projects on iPad (and in some cases on iPhone): the projects folder is now created reliably, file copying was made resilient, and a clear message is shown if anything fails. • When you Cancel from the trim preview, your chosen start and end times are now kept, so you can adjust and retry without entering them again. • Fixed centisecond pickers in time fields sometimes not reflecting the chosen value (notably the start time not responding when moved backwards): time is now computed with integer arithmetic. • Fixed the share sheet offering no sharing options (only saving) for some audio formats (WAV, AIFF): the file type is now declared explicitly to the system. The format picker also explains which format is compatible with every app. • Every video operation (trim, split, mute, add audio, sound effect, filter, insert silence) now goes through a single, safe export path. This prevents black video, video turning into audio, or corrupted output on iPhone HDR (Dolby Vision) recordings at the root: the app verifies its own output and rebuilds it with the safest method when needed. • Sharing was made safe everywhere in the app; an empty or broken file is caught before sharing, preventing the "cannot be shared" error. • Video quality and resolution are preserved in every operation. The improvements were reviewed across the whole app as a coherent whole.

VERSION 2.8 This update focuses on stability and audio tools. FIXES • Fixed silence trimming turning video into audio or producing a black picture, including on iPhone HDR (Dolby Vision) recordings. Video always stays video, rebuilt with the safest method automatically when needed. • Fixed export failing or coming out empty when a sound effect or audio filter is added; an empty file is now caught before sharing and a clear message is shown. Videos with sound effects appearing broken in the gallery are also fixed. • Fixed being unable to paste text from the clipboard into the subtitle field. NEW • Audio Compressor: evens out volume differences so whispers are audible and shouts aren't harsh, with an optional Limiter for broadcast-ready sound. In the editor and in Extra Tools. • Fade Out: gently lowers the audio to silence toward the end of the recording, for a professional ending. In videos the picture is untouched. • Insert Silence: adds silence of your chosen length at the position you pick — ideal for leaving a gap after a sound effect before speech begins. In the editor and in Extra Tools. • Custom durations in Smart Split: set each part's length yourself; any remainder goes to the last part. • Transcription now works end-to-end on long recordings.

VERSION 2.7 NEW • Audio Compressor: evens out volume differences — whispers become audible, shouts stop being harsh. Available in the editor and in Extra Tools, with an optional Limiter ceiling guard; decide by listening to before/after. • Advanced Speed Change: apply to the whole media or a chosen range, eight speeds from 0.25x to 4x; adjust while listening to a sample. Pitch and quality are preserved. • 7 new audio filters: three new robots, Helium, Ghost, Stadium Announcer and Giant. Underwater and cave filters were also redesigned; there are three caves now. • Custom durations in Smart Split: instead of equal parts, set each part's length yourself; any remainder goes to the last part, with live duration info guiding you. • Visual effects are now saved with the project and covered by undo. FIXES • Fixed being unable to export after adding audio to a video, and options staying dimmed. • Fixed visual effects not appearing in the preview and export. • Permanently fixed silence trimming turning some videos into audio-only. • Fixed the watermark position: the corner you choose now matches the exported video. • Fixed sharing: exported content now transfers to every app without errors. • Fixed videos playing silently when the phone's silent switch is on. • Transcription now works end-to-end on long recordings: even an hour of audio is recognized piece by piece and fully transcribed. • Fixed exported video coming out completely black in projects made of several joined clips.

VERSION 2.6 WHAT’S NEW • 130 HD sound effects + sound import from royalty-free sources. • Effect volume, playback duration and VoiceOver-friendly duration labels. • Text watermark with position, size, opacity and time controls. • Live Preview for effects, filters, subtitles and watermark. • Smart Tools: Sound Map, Filler Cleanup and Scene Draft. • Auto-save drafts in Audio Description. • Live audio mix preview with smooth music fade. • Scene Draft now supports Photos videos. • Contributors page. • Advanced Speed Change (0.25x–4x) with range support and preserved quality. • 20 cinematic visual effects with live preview. FIXES • Fixed audio description resource leak and empty project issue. • Fixed insert, undo/redo and subtitle/filter warnings. • Fixed Add Audio freeze with large/cloud files. • Fixed silence trimming converting videos into audio. • Improved filler-word detection and multilingual error messages.

zEdit 2.5 — What's New NEW FEATURES • Sound Effects: 139 ready-made effects in 11 categories to place on the timeline — applause, laughter, win/lose stings, percussion, nature, animals, mechanical sounds, cinematic transitions and comedy classics. All effects are generated inside the app and are completely royalty-free. Preview each one before adding, choose the start with hundredth-of-a-second precision; effects are saved with your project and mixed into the audio on export. • Audio Filters: 10 filters that transform a chosen range of your audio — Echo, Cave Echo, Room Reverb, Telephone, Old Radio, Underwater, Megaphone, Robot, Tremolo, Muffled. Start and end are set with accessible fields, every filter can be previewed, and logic errors are reported with clear messages. • Undo and Redo: Actions like trimming and volume are undone with one tap; the history is saved with the project. Better yet, subtitles, effects and filters removed by a time-changing action come back to their lists when you undo that action. • Insert: Place new content right into the middle of your video at the second you choose; existing content is split and continues without interruption. • Smart Video/Audio Split: Divide a file into equal parts, delivered as one numbered ZIP. Video is not re-encoded: fast and lossless. • Receive via Share: Content shared from Voice Memos, Photos or Files greets you straight in the Editing Area. • 4 New Languages: Chinese (Simplified), Korean, Ukrainian and Portuguese — the app is now complete in 13 languages. • Audio Merge renewed: Real file names are shown, files can be reordered with move up/down (including VoiceOver custom actions), each file can be previewed before merging; merging always follows the visible list order. FIXES • The rare data loss in audio description projects is fully eliminated; your work now saves automatically — closing the app can no longer lose a description. • Speech synthesis stalls behind the "Audio could not be created" error are fixed; unedited texts are now genuinely skipped. • The freeze during noise reduction is fixed; processing runs in the background and the interface stays responsive. • Music drifting by a few seconds in photo slideshows is fixed at the root. • Share sheets that could open empty are repaired; volume adjustment is reliable on long recordings; audio overlay and silence trimming are significantly faster. • Many accessibility and stability improvements.
