FlowCompressor 3.0 makes compression, editing and AI recipes easier to use. • Optional Private Cloud Compute: generate reviewable AI recipes and ask editing questions without an API key or a local model download for this engine. Requires a compatible Mac with macOS 27 or later, Apple Intelligence availability, internet and consent. A daily usage allowance applies. • Quick Edit: trim, crop and rotate individual Batch and Video Merger clips with a visual preview, without writing a recipe. • More merger transitions: choose a separate effect and duration at each join, mix transition styles and preview the effect before exporting. • ProRes editing exports: choose Proxy, LT, 422 or 422 HQ MOV files in Format. Built-in Editing Proxy shortcuts select 720p or 1080p caps. SDR sources only; uses Standard. Editing files may be larger than their source. • Preview export packs: create several desktop, phone and tablet preview variants together, review framing and inspect each file's technical report. • File size goals, short before/after comparisons, saved presets and unfinished queue recovery. • Improved export reliability, cancellation, audio/video synchronization and existing-file protection. Private Cloud Compute sends typed requests and numbered input media types to Apple. Media files and automatically obtained filenames and paths are not sent; anything you type is included. Media processing stays on your Mac. Turn off cloud access in AI settings. Auto uses local engines; Local Gemma separately requires a model download. Estimates and comparisons cover short samples. Technical checks do not guarantee approval by a distribution platform.

Make better compression choices and keep your exports under control. • Preview estimated output size and space savings before starting a batch. Compare quality presets, formats, processing engines, and maximum video dimensions. • Choose H.264, HEVC, or AV1 for batch compression, with options to limit video dimensions to 4K, 1080p, or 720p. AV1 uses Standard encoding. • Export safely: existing files are preserved, matching filenames receive numbered names, and completed videos are saved only after processing finishes. Batch outputs that exceed the input size are discarded. • Stop exports more reliably. Completed files remain saved, and unfinished batch files wait for you to retry. • Keep batch settings consistent while browsing other workspaces. Settings changes and newly added videos apply to your next run. • Find clearer controls in the updated workspace and practical guidance in the new Help window. Open it from the toolbar or the Help menu. The new About window includes version details, support, privacy, website, and rating links. Size previews are estimates based on short samples; final output sizes may vary.

Choose the best format for every batch with new H.264, HEVC, and AV1 export options. Set a maximum output size of 4K, 1080p, or 720p, with resolution-aware compression tuned for smaller files and dependable playback. The main window has been reorganized to make formats, quality, file selection, and processing controls easier to find. This update also improves queued batch consistency, rotated-video handling, local AI model loading, and overall export reliability.

Switched Local Gemma to more efficient OptiQ models. Improved the AI Recipe system for App Store Preview exports. Added better support for speed changes and visible transitions such as wipe, pixelize, and fade effects.

FlowCompressor 2.1.1 fixes an Apple Intelligence recipe issue that could show a context-window error for simple AI Recipe prompts.

What’s New in FlowCompressor 2.1.0 Better AI Recipe support for speed changes. Add transitions inside a clip or between clips. New prompt examples for slowing sections, merging clips, and named transitions. Fixed the Batch Compress progress layout. Example prompts: -Slow source seconds 8-18 to 0.5x speed, keep the rest normal, add a pixelize transition at the speed-change points, and export H.264 MP4. -Join file 1 and file 2 with a 1-second wipe_left transition. Keep file 1 normal and slow file 2 to 0.5x speed. Export H.264 MP4.

FlowCompressor 2 is here with AI Recipe, a new way to turn plain-language requests into polished video edits. Describe what you want, and FlowCompressor builds the workflow for you. Create PNG-to-MP4 slideshows, 2x2 comparison grids, side-by-side layouts, App Store preview exports, crops, rotations, flips, labels, overlays, and more from simple prompts. For example: • “Create a 2x2 comparison grid from four videos.” • “Turn these PNG images into a fast MP4 movie.” • “Add A, B, C, and D labels to each section.” • “Crop to a square, rotate, resize, and export as H.264 MP4.” AI Recipe makes advanced video tasks feel natural, while still keeping everything local on your Mac. NEW IN VERSION 2 AI RECIPE Use plain English to create video edits. FlowCompressor can generate recipes for video grids, previews, PNG slideshows, resizing, cropping, rotating, flipping, labels, and export settings. PNG TO MOVIE Turn selected PNG images into fast MP4 slideshows. Keep images in filename order, fit them inside a 1920×1080 canvas, preserve the full image, and export high-quality H.264 MP4 files. BETTER MULTI-VIDEO LAYOUTS Create cleaner side-by-side comparisons and 2x2 grids. Labels, overlays, filename ordering, and multi-video layouts are more reliable. APP STORE PREVIEW WORKFLOWS Prepare screen recordings for App Store Connect with export settings designed for preview-style videos. FlowCompressor can help trim, resize, normalize, and export clean H.264 MP4 files. IMPROVED STABILITY Version 2 improves compression reliability, Apple native compression handling, large PNG image sequence support, fast slideshow exports, and overall workflow behavior. CORE FEATURES BATCH COMPRESSION Drag and drop many videos at once and let FlowCompressor process them efficiently. It is built for large batches, screen recordings, mobile clips, drone footage, and everyday video cleanup. QUALITY PRESETS Choose the output that fits your goal: smaller files, balanced compression, high quality, or maximum-quality workflows. Reduce storage use while keeping videos sharp and easy to share. VIDEO MERGER Combine multiple clips into one polished video. Use hard cuts or smooth crossfades, and create clean merged outputs without leaving the app. GPU HARDWARE ENCODING Use Apple Silicon’s dedicated Media Engine through VideoToolbox hardware encoding. GPU mode helps large exports finish faster while reducing CPU load. APP STORE VIDEO RESIZER Export to exact App Store Connect dimensions for Mac, iPhone, and iPad previews. Supported preview sizes include: • Mac: 1280×800 or 1920×1200 • iPhone: 6.7" 886×1920 or 5.5" 900×1600 • iPad: 1200×1600 portrait or 1600×1200 landscape FORMAT SUPPORT Work with MP4, MOV, MKV, AVI, WMV, MXF, GoPro LRV, and other common video formats. PRIVACY FIRST All processing happens locally on your Mac. Your videos are never uploaded or sent to a cloud service. FLOWCOMPRESSOR IS GREAT FOR: • Compressing large video libraries • Preparing videos for email, Slack, Discord, and cloud uploads • Creating App Store preview videos • Building side-by-side video comparisons • Turning PNG image sequences into MP4 movies • Merging travel clips, screen recordings, and project highlights • Archiving high-resolution projects without buying more storage FlowCompressor 2 is the most capable version yet: compress, merge, resize, preview, compare, and create with AI Recipe, all locally on your Mac.
