Cross Disolve Length Beyond Two Clips

I'm trying to add a single cross disolve across the length of four clips. But FCP only allows me to drag the length of the cross dissolve accross the two clips in the middle before it maxes out. Can't figure it out or find the answer in searches. Any thoughts welcome - thanks!

The two middle clips are freeze frames from the preceeding and leading clips which are both Burns effect. So I want a single transition/dissolve to simply spread accross all of them if that makes sense!


Ah! Ok, then Tom's advice is a solid one.

To be more precise, select the first two clips, and make a compound; select the last two clips, and make another compound. Then apply a transition between both compounds.


TIP: before making each compound, you may want to augment the duration of the still image; make the compound and then trim it back to the original duration. This way you will be creating "handles", which will be of great use when creating the transition.

Yes I was creating the compound clips as stated but was getting the 'not enough media' message when adding the cross dissolve. It appears I have to re-work the clip lengths to account for this which makes the edit a bit confusing (when synching to music). I think I can figure it out now. It shouldn't be so complicated!

See my TIP above. It is not complicated. Just add, say, 1 second to the still duration (clip B), make the compound, and trim back 1 second. Do the same on the other side: add 1 second to still duration (clip C), make the compound, and trim back 1 second from the start.

Now you have enough material for a dissolve of up to 2 seconds.

Can you elaborate a bit on the looks that you are after?


As I said before, a cross dissolve is between two clips. The way it works is by gradually reducing the opacity of one clip while increasing the opacity of the other clip, so you start seeing only clip "A", and gradually the two are "mixed together", until finally you only see "B".

If you want to gradually start with A, dissolve into B, then into C, then into D, then use three dissolves.


If you want to somehow "mix" all four clips, then just a transition won't do it.

You could perhaps stack them all, and vary their opacities over time, but it is unclear how that would look, at least without some more information on what you really are trying for.

A cross dissolve is a transition. By definition, a transition works between two clips.

As Tom said, a screenshot of what you have might be helpful.


It is unclear just what you want to achieve, maybe you want not want but three dissolves (like from A to B to C to D),

or maybe it is something else. Whatever it is, I am sure it is feasible, put perhaps not with just one cross dissolve.


EDIT: I see now that you have already posted a screenshot. I will look at it and report back

I think it's lost in translation. The left/right thing was referring to the timeline position. They're not the same image, it's a still image with lots of Ken Burns applied and freeze frames in between. It's a bit complicated! There's a legitimate scenario to apply cross dissolve across a KB clip with a freeze frame at the end, and a new KB clip that has a freeze Fram at the beginning. Compound clips does solve the issue.

Why are you splitting the same still into 4 clips? If you just want to darken the beginning and end of the still, one clip should be enough. I have no idea what you're trying to do.

I think the OP explained it. He has applied Ken Burns to both clips, and then added freeze frames in the center in order to apply the transition:

Q1: Is the clip "Hasegawa_Tohaku_-_Pine_Trees" a still image or a freeze frame?

Q2: If the four clips are A, B, C, and D from the left, is KenBurns applied to A and D?

Q3: What would happen if you added a freeze frame to A and D, which already have KenBurns applied, and applied a cross dissolve between them? *I think it's a meaningless effect.

Q4: Why does the OP insist on using cross dissolve? What does it really want to do?

Q5: Are the originals from A to D the same still images? The OP explains that they are different still images, but there is no basis for that. Because the screenshots have the same clip names.
