Rendering Oddity
I have a little weird problem, it involves nested sequences a few levels deep, here goes:
“Show Vision” contains five video layers:
– V1: ProRes HQ media
– V2: A TV show ‘bug’ in the bottom right (TGA file).
– V3-5: Boris 3D Title layers making up a simple ‘score’ graphic (two names on V2, score of one on V3, score for the other on V4)“Part 3 Master” contains two video layers:
– V1: The ‘Show Vision’ sequence
– V2: A shot of a TV“Episode Compile” contains one layer:
– V1: The ‘Part 3 Master’ sequenceFor this one shot, in the Compile sequence where I am rendering it all, the score graphic (built in the ‘Show Vision’ sequence) doesn’t show one of the scores.
In this part of the ‘Part 3 Master’ sequence the ‘Show Vision’ sequence has been split, and a shot of a TV put over it. The Show Vision has had a few effects added to it, a basic distort applied and the TV shot has a basic hole cut in it with a 4-point mask. After that shot the Show Vision sequence is full frame again, with a few effects applied to it.
If I park the playhead over the shot on the ‘Part 3 Master’ sequence then I see what I expect, the full score board (three text elements), the bug and the vision, all scaled and distorted to fit in the hole in the TV image. However with that sequence then nested into my compile master and rendered I see exactly the same thing, but one of the score layers (what would be V5 in the Show Vision sequence) is absent.
Is this some other aspect I nesting I am not understanding?

yes, it can be buggy at times.
It’s a necessary evil at times, but I avoid it at all costs.

When I first encountered Avid’s effects methods, especially putting effects on ’empty’ tracks above vision I thought it was a little crazy, but for things like this it is so much simpler. I have a handful of effects that I need to apply to a whole section of the sequence (including uniformly to the graphics and other elements that make up the primary vision).
As far as I can tell in this case there seems to be some sort of maximum recursion limit or something, the effect on the highest track simply doesn’t get processed when that sequence is included in one more comp. It’s mental and really really annoying.
