Features
Everything you need for MOV to MP4
AI auto-captions
Local Whisper AI transcribes speech from your MOV recording and burns subtitles into the output MP4. Seven styles — Subtle, Bold, Cinematic, Block — ideal for social media, tutorials, and accessibility.
AI voiceover narration
Replace or supplement your original audio with Kokoro TTS (14 voices). Write a script, pick a voice, and the narration is generated locally and mixed into your converted MP4 automatically.
Background music library
Search 500,000 CC0 tracks by mood or keyword, or upload your own audio. Music is looped and trimmed to match your video's exact duration. Auto-ducked under speech when voiceover is active.
VFR-safe conversion
iPhone and Mac screen recordings often have variable frame rates that cause choppy playback. Animation Machine forces constant frame rate output, so your converted MP4 plays smoothly everywhere.
FAQ
MOV to MP4 — Common Questions
Why can't I use MOV files on all platforms?
MOV is Apple's QuickTime container format. While it works natively on Mac and iOS, it's not universally supported on Windows, Android, and most social media platforms. Converting to MP4 (H.264) gives you a file that plays everywhere.
Does Animation Machine handle variable frame rate MOV files from iPhones?
Yes. iPhone MOV recordings often have variable frame rates, which can cause choppy playback or audio sync issues in many converters. Animation Machine uses FFmpeg with constant frame rate output to ensure smooth, perfectly synced playback.
Can I add AI captions to my MOV recording?
Yes. Enable AI captions and local Whisper will transcribe speech from your MOV recording, then burn subtitles into the converted MP4. Seven styles are available: Subtle, Bold, Cinematic, and Block.
Can I add background music to the converted video?
Yes. Search our 500,000-track CC0 music library by mood (Cinematic, Upbeat, Lo-fi, Corporate, etc.) or upload your own MP3/WAV/M4A. The music is auto-trimmed to match your video duration.
What resolution options are available?
Export at 1920×1080 (landscape), 1280×720 (720p), 1080×1920 (portrait), 1080×1080 (square), or 3840×2160 (4K). Platform presets for TikTok, YouTube, Instagram, and Twitter are also available for one-click format selection.
Can I add an intro or outro card to my MOV-to-MP4 export?
Yes. Add a branded outro card (title + optional subtitle on a dark background) that appends to the end of the converted video. Duration is 3–8 seconds. Intro cards are also available.
How much does Animation Machine cost?
Animation Machine is $5 per month — or $36 per year (save 40%) — with unlimited renders. No per-export fees. Cancel anytime from your account settings.
