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!
