Useing QuickTime files
I have gotten some Quitime files. Can’t seem to be able to open them?
iPhone 12 Pro Max, iOS 18
On what device (with what version OS) are you trying to open these media files?
Do you know the origin? Are these old files, or new files? Old files may use codecs that are no longer supported. New files may use modern codecs that older systems may not support. Do you need just playback, or more advanced use? Consider VLC or IINA on Mac. Those play almost any media file, new or old.
