transitions within multicam

[Jacob Brown]

So i was doing the compound, and i figured out how to open it in timeline and make handles, but still withe the dissolve transition, for some reason, FCPX ignores the second white layer below during the transition.

I just tried putting the white on top of the image though, and set opacity to darken, and it seems to work now.

Very strange the way it ignores the white layer when its below. i feel like this is something unique to multicam?

It’s not ignoring the white, what’s happening is that by adding the white you have a double white layer where the image is and a single white layer over the black portion. It’s happens in Legacy as well, compounds solve this. I’ve never done it with a multicam though, it’s very possible that there’s some funky stuff going on, I’ll see if I can recreate the problem when I get home.

You could move the Multicam to the secondary storyline and layer the portions adding dissolves to each, by default X adds them at the beginning and end of a storyline. Perhaps there’s something going on with the cross dissolve and the multicam.

yeah i’m not 100% sure but i dont think i have had this exact issue with non-multicam composites before.

but putting the white layer on top and setting the blend to darken seems to work fine.

luckily it treats empty space no as dark but as empty, that saves me.

Where are you adding the white layer beneath? I see in your original post a dissolve between two multicam shots and a white generator below. That would definitely cause the problem you’re seeing because essentially you’re dissolving two clips that aren’t solid (because you moved them) and the result of that dissolve is being placed over white. So during the dissolve you have a blend of their two alphas. But I thought you had created some compounds where the white was inside the compounds, and had dissolved between the two compounds. If that doesn’t work, yep its a bug. Legacy was full of that stuff. It never really understood how to dissolve alphas. And since it appears they copied and pasted the keyframing engine, they probably copied and pasted some of the keying engine code too.

Dissolving between compositing/blending modes generally never produces results that are what you’d want. If you found a way that works. Go with it.

So what were the transparency settings on your compound clip?

[Nikolas Bäurle]

I left the default settings . Blend Mode: Normal opacity:100%

Perhaps the difference is that I shifted the frames in the main timeline not within the angle editor.

Within the angle editor, ever frame was full frame. But then in the timeline, after edit complete, I was animating movement of the frames to make the figure look like it was moving around.

The only way the transition would then work for me was to create the compound clip with the white layer on top with the transparency set to darken. Who knows 🙂
