That YT comment is incorrect. Quality will be identical either way. I personally would nest the sequences for convenience, though.
Jim is correct. There are huge advantages to using nested sequences instead of copying/pasting. The sequences are not in any way transcoded. There is no generational loss. Check it for yourself. Nest one sequence in another, and then nest that one, and that one, etc. After about 20 nests, you would be able to see a problem if there was going to be one.
Thank you Jim and Steven. This totally puts my mind at ease.
I did do a couple "nests" and didn't see a difference, but since I heard there was a possible degredation, I wanted expert advice before committng myself to a course of action.
So, yes, I have four layers of nests now: the individual sequences are nested within the chapter sequence, which is nested within the project sequence which is finally nested into the master sequence.
Sounds like a common sense workflow to me! Well organized. And you can go all the back into the individual sequences to make changes and it shows up in the master sequence.
Just pay attention when you increase or decrease the duration of a sequence. It doesn't ripple the master sequence. You have to drag out the handles manually.
Good advice! Thanks again!
