could an approach be to:

1. embed my comp in a new comp and time stretch down to target length (1:01:06) or a ratio of 0.90625.
2. take all source videos and slow them down by this ratio (creating a new comp for each).
3. Use these slowed down comps as the sources in the target comp.

The logic here is that my slowed down source videos would then get sped up back to their true speed, while the layers and keyframes would all be scaled appropriately?

If this could work – is there a short cut to doing this other than creating 20 new comps and applying a timestretch to each?

1. You are quite right. I am a dolt. 160 BPM will result in a shorter comp!
2. If I shorten the comp length in composition settings, it does indeed shorten the comp, but as far as I can see, it does nothing to the layers/precomps within – except for cutting off those that sit at the end of the timeline.

Here’s a mini version of what I would like to do:

Let’s pretend my comp is 1:00:00 long and I wish to halve its length to 00:30:00.

Now let’s pretend I have 3 layers. 2 are 30 seconds length and one is 20 seconds length. Layer 2 overlaps layer one by 10 seconds and layer 3 overlaps layer 2 by 10 seconds. Each overlap has a cross dissolve. When I shrink the comp, I would hope that:

1. The 30 second layers become 15 second duration (framerate/video speed unchanged) and the 20 second layer becomes 10 secs.

2. The overlap (and cross dissolve effect) also shrinks from 10 secs to 5 secs.

How do I do this? With 3 layers, and a simple 50% ratio, I could do it quickly by hand, but with 30 layers and a ration of 0.90625 – this quickly becomes unworkable!

would it be possible to repost this tool as the link seems to have died. Thanks.
