I see this as well. Nests can sometimes act funky when something is dropped on top of them. I saw a lot of this on a recent project. 16 segments, each a nest, combined to one master timeline for output. Alpha transitions overlaid between some of the nests, and a few GFX overlaid at the head of a couple of the other nests. Occasionally, the nest under the GFX would play at the wrong spot, then jump to the right spot once it has passed the GFX overlay.
To fix this before outputting the broadcast masters one of two things can happen.
1: export the nests as self contained QT’s, then re-import then add your GFX/TCG filter,.
or if you still need the flexibility to make changes to those nests as I did, and want those changes to be reflected into your master sequence with out having to export/import/export/import… render.. render.. so on…
2: I found that if i put the playhead over the trouble spot, double clicked on the nest at that spot, the nest would open, then id switch back the the problem sequence and the nest would now display the right frame in the master.
If that didn’t work as it didn’t in all cases, add a razor slice after the problem area, then bring the opacity down, then up of the problem area and re-render that spot.
so,,, anyways,, if you don’t need to make changes to the nested sequences, your better off exporting a self contained QT before adding the TCG,, otherwise you’ll need to jump through a couple hoops!
***another cool way of adding TC to a screener, especially if you are going to use compressor to crunch out some web or DVD copies,, is to export self contained QT movies from FCP, then use compressor to add the TC Burn as you encode. This is super efficient especially if you have a multi-core machine set up to render in clusters…
