Thanks everyone for the comments! Good suggestions. But just to keep expectations in check: while it would be nice to do everything that is needed, realistically right now amount of people working on VSE sums up to… about one (i.e. pretty much two people, both part time).
- VSE vs compositor, nodes, etc. – yes, as mentioned, that is generally wanted. No concrete design in how exactly that would look just yet.
- VSE data outside of the scene, or some other ways to edit sequence timeline while being able to tweak some other scene at the same time – yes, that is part of the whole “larger picture” section.
- Hardware acceleration (NVENC etc) – yup, under GPU section.
- VSE “primary goal” – sure, while primary goal is “tools for making stories”, there is nothing that prevents you from just stiching several movie clips in VSE. No one wants to take that away or make it complicated.
