Quicktime trim option greyed out
Hi I've just been editing 8 screen recordings, and number 5 has the majority of the menu options greyed out. Its the only recording with an issue, and I can't see that its locked or any different to the other .mov files I was trimming, but equally I don't know what I'm looking for! I'm on Catalina 10.15.7 and Quicktime 10.5. Thank you!
