Still trying to get this MP4 to play...

Going back to your original thread...

I grabbed another .mp4 file from a different source, and it plays fine. So It seems to be specific to videos from Twitch and this laptop. I compared codec versions between this and the other machine, and they're the same.

If it's just the one file, and a file with the same codecs works fine then it's probably corrupt. Some players can play corrupt video better than others.

Transcoding will either fix it or make a garbled file. If it gets garbled then the original was almost certainly badly corrupted.

You said you'd tried the file on different Macs. This Mac is slow? Transcode it on another Mac.

It's any file from Twitch. When it was working, he would record a few a day and then edit. So it's not as simple as just resolving one file. He also doesn't have other Macs in the house he can use. Transferring 3-5 files a day, transcoding, transferring back, editing... is just a mess. It should just work. The same files on two other Macs play fine in QT (and thus are editable in iMovie.)
