Rewrapping MP4 to MOV with CinePlay

I recently had a need to rewrap an MP4 to MOV without transcoding the existing H.264 video when it occurred to me that CinePlay for Mac makes an excellent rewrapping tool, despite this purpose not actually occurring to us during development.

Here's how to do it:

1. Open up the MP4 you wish to convert in CinePlay.

2. Go to File > Export.

3. Under both Video and Audio, select Don't Transcode (pass-through) and click Save.

The movie will be rewrapped to a separate MOV extremely quickly. Depending on how much video data needs to be copied over to the new file, it could be as short as a few seconds.
