Veditist: Video Speed, Reverse
Batch Compressor & FPS Changer
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Convert every video your way — speed, reverse, frame rate, and file size — all in one pass.
Veditist is a batch video converter that turns a whole selection of clips into finished files at once.
WHY WE MADE THIS APP
Changing the speed of one video is easy. Doing it for twenty is not. Most apps make you open a clip, set it up, export it, then start over from the beginning. Veditist was built so you only do that once: pick your videos, set them up, and let them all convert together.
WHO IT'S FOR
- Anyone with a camera roll full of clips to speed up or slow down
- Creators who need reversed video or audio for social posts
- People who want to shrink videos and free up storage
KEY FEATURES
Batch Conversion
Select multiple videos from your library and convert them in a single pass. No more exporting one clip at a time. You can also import mp4, mov, avi, mkv, webm and more from the Files app.
Speed Control
Adjust playback from 0.25x to 24x in 0.25 steps. Build a fast time lapse or a smooth slow motion clip, and preview the difference before you export.
Reverse Playback
Reverse the video, the audio, or both. Veditist rebuilds the file so it truly plays backwards, not just in the player.
Frame Rate & Compression
Output at 24, 30, 60, or 120 fps and choose how much to compress. Make videos smaller without touching the originals.
Flip & Mute
Flip vertically, horizontally, or both. Turn the audio off to export a silent clip.
Per-Video Settings
Every clip can carry its own speed, reverse mode, flips, frame rate, and compression. Review the whole queue before conversion starts, and adjust the settings to convert again after exporting.
Shortcut Mode
Turn it on and a single tap on any video starts converting right away with your saved settings — ideal if you always use the same setup.
Keeps Going in the Background
Conversion continues after you leave the app, and Veditist picks up where it left off if it gets interrupted.
Saving & Cleanup
Save finished videos to a Veditist album in Photos or share them straight away. You can also have the originals deleted automatically once the results are saved.
FREE AND PRO
Veditist is free to use: convert up to 4 videos at a time, adjust speed from 0.25x to 8x, reverse video or audio, flip, mute, change frame rate, and compress. Veditist PRO removes the batch limit and unlocks speeds up to 24x, 24 fps output, every compression level, and every color theme.
WORRY-FREE BY DESIGN
- Every conversion runs on your device. Your videos are never uploaded to a server.
- Your original videos are never modified. Results are saved as new files you choose to keep or discard.
---
Photo library access is used to load the videos you select and to save the videos you convert. Originals are deleted only when you choose to delete them.
