FAQ: Final Cut Pro: Transitions

One of the most common questions I get from former students in Final Cut Pro is this:

How come sometimes I can't put my transition in the place that I want it? (see pic)



Well, while there could be a couple of reasons, the most common reason is due to "handles" on the media.

Imagine it like this.

The way a transition works, in this case the cross dissolve, it grabs the 15 frames before and after the edit point for both clips to create an evenly fading transition.














Since there is available data on either side, Final Cut Pro will use these frames to form part of the transition, although you originally edited this out. So be warned, if you are using transitions, be mindful of what is in this handle. There is probably a reason you edited it in the first place.

You may come across flashes of other shots, or an errant clapper, because of this.

If you have two clips together that do not have an extra 15 frames in either direction, then this transition cannot occur.















See how in the diagram, the transition does not have enough frames from Clip 2 to make a full transition. You could choose to have this transition "begin at the edit", as there is more than enough handle in Clip 1 to accommodate.

If your transition cannot happen, you will likely see the little 'x' next to the transition icon inside of Final Cut Pro.

One neat thing about Premiere (though I am working on memory here - so don't quote me) is that it will interpret every frame before the first (or everyone after the last) as a freeze frame. This allows the transition to happen, even if you do not have the handles.

Part of the reason I bring this up, is that this can be a good workaround if you need to squeeze a couple of extra frames out of a transition. Make a freeze frame before or after the clip that needs it, then nest (precompose) it. Now the transition should work.

If all else is failing - make sure you are not putting an audio transition on the video, or vice versa. Trust me - I do this more times than I can count.
