Jurjen VersteegTime mismatch when going from child to parent comp

Hi There,

I have a really annoying problem and I can't seem to find where it comes from:

When clicking a pre-comp in your main comp, usually the time indicator matches the time you have in your main comp. (i.e. 00:30:00 in main comp, gives you 00:30:00 when clicking on pre-comp)
Now, this is no problem. But when I click back to my main comp, my time indicator shift 10 seconds back. So when I'm at 00:20:11 and I click back to my main, the timer gives me 00:10:11.

Anyone any idea which causes this sort of timing mismatch?

Thanks a lot!

Do you have "synchronize time of related items" checked in AE Preferences?

Hi Dave,

Yes, it's turned on. In new created comps I don't have this problem, so it should be something inside this specific comp.

Do the frames rates of the two comps match? As Walter suggested, did you move the nested comp in time?

If "Synchronize time of related items" is checked as Dave suggests, then you must also ensure that the comp lengths and start times are identical.

If you have moved the precomp layer's in point ten seconds forward in your main comp, they will no longer have matching timecodes. You can correct this by either moving the precomp's in point back to the beginning of the main comp, or by adjusting the precomp's starting timecode (found in composition settings) to match the timecode of its in point in the main comp.

Thanks for your responses. Both comps are the same length (2 min.) and the pre-comp is set to the first frame.
Mind that this issue only appears when I click back to the parent comp. Clicking on the pre-comp from the main comp keeps the right time, but clicking back sets my time indicator back 10 seconds.

[Jurjen Versteeg] "Mind that this issue only appears when I click back to the parent comp. Clicking on the pre-comp from the main comp keeps the right time, but clicking back sets my time indicator back 10 seconds."

Do you have two layers of the same precomp (offset in time) in the main comp?

Ah! That's it. I already thought it could be the problem, but couldn't find any duplicates, until I just found out I renamed the duplicated pre-comp. Thanks!

You're welcome.

It might be a bit confusing in the main comp, but you could snap the precomp back to matching at the first frame, then enable time remapping for that layer only to offset it in time. That will keep your CTI consistent as you move back and forth between comps.
