Create an H.264 MOV copy from a supported MP4 in your browser. This page makes the MOV itself; ordinary video export in the ChatCut editor does not offer MOV.

Why ChatCut
Write a QuickTime MOV file, rather than only changing the filename extension.
Compatible tracks are copied without re-encoding, preserving their encoded media.
Review the resulting MOV in a browser that can play its H.264 tracks.
Save a separate file for a handoff that asks for MOV.
The source and converted media stay in your browser until you download.
The local MOV output has no logo or branding added to it.
How it works
Pick a supported MP4 from your device. Keep it within 128 MB and 5 minutes.
Start the local conversion to MOV. Keep this tab open until the file is ready.
Check the result, save the converted copy, or restart with another video.
Learn
MOV is the QuickTime container associated with Apple, while MP4 is a separate container frequently used for sharing video. Both can package H.264 picture data. Choosing a MOV extension does not choose ProRes, create transparency or improve detail. Before preparing a handoff, ask whether the recipient needs the container itself or a specific editing codec. This page is suitable for a supported H.264 MOV request, not a request for a ProRes editing master.
This tool writes a real QuickTime container with H.264 video and AAC sound when audio exists. If the primary tracks already use those codecs, they can be copied without encoding them again. That preserves the encoded media in those tracks, but does not mean the entire file remains identical. The packaging changes, and additional soundtracks, subtitles and attachments are not carried over. Keep the source MP4 for any tracks or metadata needed outside the playback copy.
A supported track that does not match H.264 or AAC is re-encoded. Video encoding targets 8 Mbps, and audio encoding targets 192 kbps. The browser must be able to handle the source and destination codecs for that step to work. H.264 encoding rounds odd frame dimensions up to even values without cropping the image. These changes may affect size or quality, so a smaller source does not guarantee a smaller converted file.
Use the result preview where the browser can play H.264 MOV, then open the downloaded copy in the application that requested it. Check sound, duration and a section with movement before sending the file onward. This standalone page produces the MOV separately from the ordinary ChatCut video export panel. It does not add an alpha channel or produce ProRes. Retain the original when you need a broadly shareable copy as well as the requested QuickTime package.
Use cases
Prepare a short H.264 MOV when a recipient requests the QuickTime container.
Try MOV packaging for a workflow that accepts H.264 in MOV.
Retain an MP4 for sharing and a MOV for a specific handoff.
Keep editing
Add your downloaded file in ChatCut to trim it, add captions or make a vertical cut. Manual editing and export do not use credits; built-in Agent requests do.

FAQ
No. It creates H.264 video with AAC audio when present, inside MOV. It does not create ProRes or an editing intermediate.
Not from the ordinary video export panel. This standalone local converter creates MOV separately; transparent motion-graphics export is a different workflow.
Compatible H.264 and AAC tracks can be copied without re-encoding. Other supported codecs are re-encoded and can change quality.
No. A different container cannot add detail or undo prior compression. Keep the source file for reference.
No. This H.264 MOV output does not add or preserve alpha. A MOV extension alone does not mean the file is ProRes or transparent.
Yes. Conversion on this page is free, needs no sign-up and adds no watermark. Continuing in ChatCut is separate: built-in Agent messages use credits; manual editing and export do not.
No. The conversion engine reads and writes media inside your browser. If you choose to continue in ChatCut, add the downloaded file there yourself.
