If I export a Premiere Pro composition containing After Effects linked compositions into Speedgrade, will SpeedGrade be able to read and grade those Linked Compositions? (the clips that were altered in After Effects).
On that note, is there a standard workflow hierarchy between Premiere, After Effects and Speedgrade? Should one come before the other? (ie should I color grade and THEN worry about effects, or should I do effects BEFORE color grading, or does the order not matter?)
Speedgrade is currently the black sheep. It's a recent acquisition for Adobe and they decided, rather than integrating the program tightly, to release the program quickly with minimal updates. It's not as bad as it seems, as that decision allowed them to quickly bring a normally $20,000 niche program to the mass market (Much like Blackmagic did for DaVinci Resolve).
Speedgrade grades footage, and a more limited scope of formats than PPro or AE.
If you export to Speedgrade within Premiere, it's actually rendering an intermediate frame sequence of DPX images. It's not dynamically linked to anything, it's already rendered.
Alternately, the only other way to bring in footage is to load an EDL and link real footage. Speedgrade will not respect dynamic linked footage unless it's been rendered and linked to an actual file or image sequence.
In standard production color grading is the last step done to visual material. You may have to do some light color correction during effects and compositing (AE work, basically) but setting a look should be done in Speedgrade as part of finishing.
