Apple Vision Pro is now available in the U.S.

Duration of video/still/transition

Fairly new to FCPX but having problems adjusting the duration of clips etc. Running version 10.7 on iMac with Sanoma 14.1.2.


I use a mixture of stills and video segments for most of my stuff, the duration of which is commonly a few seconds - generally longer for the video clips. When I right click on a video segment, still photo or even a transition, the answer is commonly not what I type. Whole numbers seem to be OK, but fractions vary. e.g. if I type "400" the duration goes to 4:00 as expected. However, if I type "450", the duration goes to 6:02. No gaps or colons etc are used when I type. The errors seem to be consistent, with each other, i,e, 450 will always produce 6:02, 550 produces 7:02 etc. It also happens which ever way I change the duration, e.g.using modify in the menu or the shortcut keys. This is making it difficult to work with!


Any help and guidance would be appreciated very much!

iMac 21.5″, macOS 14.1

450=4 seconds and 50 frames. If your project setting is 25fps, that means 6 seconds. I think the remaining 2 frames are the difference adjustment when the fps of the media and the fps of the project do not match. *fps=frames per second


Please show me a screenshot of the fps of the clip you want to change the project settings and duration of.

Thank you LocAlicia and Luis. The answer is in what you say and I don't need to send the screenshots: last 2 digits are frame numbers, NOT parts of a second. Video is running at 23.98 fps, so 4.5 seconds is 412 or 4:12. I really should read the guidance notes properly rather than tearing my hair out.


Thank you both again. i appreciate you taking the time to answer.
