Move multiple keyframes via a control?
on Sep 3, 2018 at 2:26:40 pm

Hi folks,

I'm going to ask a question that I've often thought about, but never explored more that a bit of an internet search.

Is there some deep dive way to move a number of keyframes along the timeline with one single control point?

For example, let's say I have ten layers, with keyframes on each layer at 15 second intervals, each doing 'something'. And let's say just for fun another layer has it's in point at our 15 sec mark.

I'd like to adjust the timing of everything that happens at 15' and move it to '16, but by just moving one control point (or marker etc), rather that adjusting every property manually.

Any ideas?

Cheers,

Moog

As I see it that is practically the same as time remapping, so that might be the more straightforward solution.

I don't think that would work, given that some of the proposed layers are footage.

Sorry - new parameters i know 😉

Thanks though.

There's always the old-school method of lassoing desired keyframes, moving the timeline cursor to the desired spot and shift-dragging.

Hi Dave,

Thanks for the input.

This is actually the thing I'm looking to work to avoiding. ☺

Cheers though,

M

Next idea: Time Remap every layer you want to do this with. Use one layer to set the time, pick-whip time value of that one layer for the rest. That way you can choose which layers will be affected, which won't, skipping your footage layers, for instance.

Not exactly what you're asking for, but there is a very handy script called Rift that lets you easily shift keyframes, layer inpoints, etc. https://aescripts.com/rift/

Premiere Pro has a feature called responsive design time that sounds a bit similar. If you look into it and it sounds like it might be what you want, I believe there's a feature request to add it to AE at the Adobe After Effects uservoice you can upvote. ☺

If you're not already using expressions on your properties, you could do this:

1. Create a new null, name it "RETIMER"

2. Add a Slider Effect, name it "time"

3. Add two keyframes for time: one "0" keyframe at the beginning, and one "10" keyframe 10 seconds in. (Replace that last keyframe with whatever timescale is appropriate for you, but be sure to use a value in seconds.)

4. Add this expression to every property that you want to be affected by the global retimer:
valueAtTime(thisComp.layer("RETIMER").effect("time")("Slider"));

5. Animate the value of the "time" slider as you like.

Voila, time remapping on select property values only.

Hi folks,

I've been out the loop for a few days, but just wanted to pop by and say thanks for all the suggestions - I'll take a look into them.

Cheers,

Moog
