Supported file formats
What you can upload, what you can export, and how to convert if your format is unusual.
INPUT (upload): - Video: MP4, MOV, WEBM - Audio: MP3, WAV, M4A - Maximum size: 500 MB - Maximum length: no hard cap, but anything over 90 minutes gets slow to edit — split it into chapters first.
OUTPUT (export): - SRT — the standard subtitle format. Works in YouTube, Vimeo, VLC, Premiere, Final Cut, DaVinci. - VTT — the web standard. Use for HTML5 <video> tracks. - ASS — styled subtitles with font, color, position. Great for stand-alone preview. - MP4 — your original video with subtitles burned in. Same resolution, H.264. - FCPXML — Final Cut Pro and DaVinci Resolve timeline format. Pro & Agency. - EDL — CMX3600 for Premiere Pro, Avid Media Composer. Pro & Agency.
If your input format isn't in our list, free converters like HandBrake or ffmpeg will turn almost anything into MP4 without quality loss. Then upload the MP4.
