MOV or MP4?

MOV is Apple’s container (used by Final Cut and iPhone); MP4 is the universal format with the best cross-platform compatibility. Here is what to watch for.

MOVFinal Cut, pro editing, Apple devices

Native in Apple ecosystem; can hold ProRes and other pro codecs (large files).

MP4 (H.264)Sharing, uploading, cross-platform

The universal standard, playable almost everywhere.

Note

If the MOV uses ProRes, converting to MP4 re-encodes it - much smaller, with slight quality loss.

FAQ

Why is MOV to MP4 conversion sometimes instant?Show
When your MOV already contains MP4-compatible codecs (H.264 video + AAC audio, e.g. files shot on iPhone), we only rewrite the container without re-encoding (stream copy). Quality, bitrate and file size stay identical - that is why it finishes in seconds.
Why is conversion slow for some MOV files, with a much smaller output?Show
MOV files from editing software often use ProRes/DNxHD video or PCM audio, which MP4 containers don't accept. These require a full re-encode to H.264 + AAC, which takes longer and produces a smaller file with slight quality loss.
Why does conversion fail sometimes?Show
Some MOV files contain codecs that are hard to remux or transcode in the browser. Try trimming to a shorter clip first.
Is my file uploaded?Show
No. The conversion runs locally by default.
