Quicktime player won't open QT movie file

"This file contains some media which isn’t compatible with QuickTime Player."

I'm on a MacStudio with OS Ventura. I think everything is updated but I can't get some movie files to play.

QuickTime won't open on my MP4 files Downloading mp4 from youtube I was always able to open them with quicktime player. Now it opens a window in which it is written that the file includes some content non compatible with quicktime player and there is no possibility to open them. If I continue I can get only the music and not the video. I have quicktime 10.5 version and MAC OS Sequoia 15.1.1 [Re-Titled by Moderator]

MacOS Sonoma will not play MP4 files I have a Mac Laptop. I was trying to play some old MP4 files that I have. It did not show the video and the noise came out garbled. I had just updated to OS Sonoma. I tested that by playing the same files on my MacMini that had not been updated. The filed played fine. Then I update my mac mini with OS Sonoma. The files no longer play. FYI, the app that is pulled is quicktime in all cases. Did OS sonoma somehow mess with Quicktime?

QuickTime edit functions all greyed out for one file I am unable to trim or perform other editing functions for one particular .MP4 file. All the editing functions are greyed out. Why is this? How can I re-enable these functions for this file? These functions are available (and function correctly) in all other .MP4 files that I have. I am on a MacBook Pro (16-inch, 2021, M1 Pro chip) macOS Ventura 13.2.1, and my Quicktime player is version 10.5 (1150.4.1). There are no updates available from Apple for my OS or for QT, so I'm on the latest version of both.

Either the video codec or audio code or something else inside the file isn’t compatible with QuickTime Player. There are many reasons why that can happen; e.g. made with old software, made with different software.

If all you need is playback, then try alternative media players: VLC or IINA.

If QuickTime compatibility is very important to you, then you may want to convert. I would suggest HandBrake, as it has nice presets for compatibility with devices.
