Transitions too short for no good reason
I am using 10.3(.4) for the first time. Can't find a thing - it's taking ages!
But my main problem is adding transitions. The first time I tried, FCP would add the thinnest of clips - no way to grab handles without zooming way in, and then refuse to allow me to "stretch" them at all. Tried ^D, but made no difference to duration.
I restarted, deleting my prefs and now I get a transition of 1" that also cannot be stretched without a red warning coming up. The clip before is 15" and the clip after 3 minutes!!! There are plenty of frames to work with.
What's going on?
Thank you for your help on this. Seriously considering going back to 10.2 if possible.
