3/16/2023 0 Comments Quicktime player export mp4But if anyone knows any websites that accept mp4 but not mov I'd be happy to test an upload and see if it works. 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. ![]() (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). 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. QuickTime Player, the default video player on Mac, is owned by Apple. 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. This test makes sure that each enumerated KSCATEGORYAUDIO and KSCATEGORYRENDER filter that exposes AC-3 format pins complies with the Microsoft Driver Development Kit documentation that is related to implementing AC-3 format pins. 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. For example, iMovie exports videos as MOV by default, and it wont let you natively play MP4, although you can export iMovie to MP4. 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. ![]() 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": +
