Choppity keeps uploads simple so you can focus on content, not codecs. These are the formats that work today across clip generation, transcription, and your library.

Supported file types

Type	Formats	Notes
Video	MP4, MOV	Most common for podcasts, webinars, and camera files
Audio only	MP3	Choppity builds clips from speech (great for podcasts)

Size and length limits

Maximum file size: 4 GB per upload
Maximum length: 3 hours
Resolution: up to 4K is accepted; files above 1080p longer than 60 minutes may be blocked

Best quality tips

For the fewest issues, export video as MP4 with H.264 video and AAC audio. MOV from iPhone or Final Cut usually works. Avoid odd containers, corrupted exports, or DRM-protected screen recordings.

What is not supported

AVI, MKV, WMV, WEBM, and other extensions are rejected at upload. Convert in HandBrake, Premiere, or DaVinci Resolve before importing.

Troubleshooting

Invalid file type: re-export as MP4.
File too large: compress or trim under 4 GB.
Too long: split the recording or upload a shorter cut.
