Question

Tracking on timeremaped layer

I need to found a workaround AE's inability to track time-remaped layer.

The workflow i see:

1.st to do tracking; then apply time-remaping

and then somehow I need to re-scale on timeline keys of the tracked data in accordance /w time-remaping track.

It seem like it should be relatively simple task to solve with a script.

I really want to avoid pre-rendering time-remaped layer prior to tracking for verity of reasons.

Anyone know of or can help write such script?

Much appreciate it.

The best solution is doing the work on the source footage and then baking the output to then time remapping the final piece. If there is a large span of time being reduced, then baking the time remapping first can sometimes be an option. For continuity sake, and your sanity, you'll wanna do one of those. I've ran into this numerous times on projects and trying to use the raw time remap data causes issues at every step of the process. It has a knack for not remaining consistent. I've had frames slide, interpret differently on different machines, etc... Having a progressive frame is always better, especially when 2d or 3D tracking is involved. The most reliable and absolute most stable option is the first one, do the work on the source clip, then flatten and time remap the flat final. Repeatable and guarantees everything stays synced.


Scripting the track keyframes to spread apart will inevitably destroy the track data. It won't interpret the same in-between frames as what the footage interpreted visuals will be.

for a brevity sake, I didn't get in to full details of what i'm trying to build in my original post, I need to use tracking data from different layers and timing of those layers need to be adjusted in order to that tracking to correspond. so in order for that to work all of it need to be located in one composition and time remapping as well as  tracking data need to exist in the same composition.
