But if anyone knows any websites that accept mp4 but not mov I'd be happy to test an upload and see if it works. I tried several times to export videos but they kept exporting with 0 bytes file size. Open the Settings app, tap iMovie, then select 'Enable 60 fps export.' Choose the movie or trailer in the Projects view that you want to share. mov, so I can't actually verify this since for all I know my tools might be ignoring the extension and autodetecting mov. Unfortunately every tool I have which takes. Welcome to SubhaStarr Thanks so much for joining my filming adventure On this lifestyle channel you'll find me exploring beautiful Northern California. (ProRes files are enormous, BTW.)Ī lot of people report that simply renaming a "mov" file to "mp4" works when the data is h.264 such as in this case. It's similarly h.264 when you record from the built-in webcam in QuickTime using the default "high" quality, but switches to ProRes if you select "maximum" quality for recording.
Just tried making a screen recording with QuickTime on my Mac and investigating it with the "mediainfo" command-line tool (available on Homebrew).
#IMOVIE EXPORT MP4 ZERO BYTES UPDATE#
UPDATE 2: So screen recordings don't use ProRes by default, they use AVC (but what profile?), so I'm unsure why so many other programs and websites reject those files because, theoretically, there should be no problem in processing them, unless the site was written by someone who doesn't understand how video files work. ProRes is very different to AVC, HEVC, etc, which explains why you need to transcode it to do anything useful with it.
UPDATE: After some research, I think that macOS screen-recordings are made using Apple's ProRes video coding, and then saved inside a QuickTime (aka MPEG-4) Container. So for this conversation to continue, we need to know what codec/video-stream-format is actually being used (I don't have a Mac ready to experiment right now, sorry). Other people are reporting the same problem: the other media software can't read Apple's screen-recording files, so I'm assuming this actually means that Apple's screen-recordings are saved using a codec other than MPEG-4 AVC or HEVC, but still in an MPEG-4 container. and Apple has been using MPEG-4 AVC and HEVC for at least a decade now, so I don't understand what the OP is complaining about: QuickTime *.mov files are MPEG-4 container files, which usually contain MPEG-4 AVC or MPEG-4 HEVC streams. But heres a workaround: convert your video to MOV with Permute. The *.mov file format is the same as MPEG-4's container format (in fact, MPEG-4's container is intentionally based on QuickTime's *.mov) and is even standardized as an ISO spec: "ISO/IEC base media file format": + Unfortunately, iMovie wont play MP4, so its impossible to preview it.
