Compound clip bug 17.4.2

PostFri Nov 26, 2021 4:11 pm

Create a new compound clip with several clips, change the running time of the compound clip to eg 10% of the original. Resolve will only look at the 1st clip in the compound clip, it doesn't behave as expected and reduce the running time of the whole compound clip

That's not how Compound Clips work. They're like a rendered sequence, not a grouping which applies changes to every clip inside them.

When you change Clip Duration, you're trimming a clip. When you do that on a Compound, you're choosing which portion of the overall Compound will be played. If you trim it to a duration only long enough to play the first clip of the Compound, that's what you'll get.

You're not applying that Change Duration to every clip within the Compound - to do that you'd need to right click on the Compound, Open In Timeline, then trim the original clips inside. Or Decompose the Compound, trim the clips on this timeline, then make a new Compound Clip afterwards.

The idea of a 'grouped' clip is a good one, and something I've wished for a lot. Nested timelines and Compound Clips are very useful, but they also have a lot of disadvantages which result from the fact that they're effectively like an automated render of the clips inside.

It could be really useful to have a group clip that behaves more like a Fusion Group - ie it can behave like a single clip, but also still exposes all the individual clips inside, and without an effective render step.

That's a feature request though, and probably quite a big one.

Are you changing the compound clip speed or trimming the compound clip?

No problems here, Change Duration and Change Speed both work as expected on a Compound Clip for me. Ditto Retime Frame/Speed.

If you're using the Change Speed dialogue, are you ticking "Ripple Timeline"? If not, the length of the Compound will be unchanged and you'd need to manually change its length to reflect the new speed. Eg if you reduce its speed by 50% without Ripple Timeline, it would now only show half of the clip(s) inside, because the length is unchanged but it's now running at only half the speed. You'd then need to double the length of the compound on the enclosing timeline to see all the content.

Perhaps show a screenshot or screen recording of what you're doing and what you're seeing.

I can't replicate it here either Thom, it works exactly as expected on my Windows system... if I trim a compound of several clips to 10% of the duration then I just see whatever 10% of the compound is left on the timeline, if I retime the compound to 10% of original duration then I see the full compound at 10x speed.
Let's have a return to the glory days, when press releases for new versions included text like "...with over 300 new features and improvements that professional editors and colorists have asked for."
