When I’ve done this in the past, I usually have my editors cut the content that is intended to be composited. First make sure it matches the pace they want, especially if the characters watching are intended to react to it.
After that, I’d usually temp comp it in the Avid, and send off the assets to VFX. Temp comp remains until you start getting comps back from VFX (at which point it becomes very important to keep meticulous track of the versions of comps coming back from VFX)
Something like that I include on your dialogue or SOT tracks, since if that has to be translated for the international market, you would want them to know about it and translate it. On the SFX track, it would be more likely to get overlooked, causing problems down the line.
