Thanks, ttoine! I agree, blender velvets is a great collection of add-ons. None of those address the effects stack or render multi-threading, however, and on complex projects with a lot of colour grading, that tends to be the bottleneck for me. I'm happy to use it otherwise, and I think the efficiency of editing in Blender is amazing in general. I'll check back with its VSE in a few years, as I do; I've been using it as an editor off and on for a decade, so I can be patient and wait for it to become my dream-editor :-)
Well, h.264 "frames" are divided into many different kinds of "frames", not all of which are complete. Even outside of Linux, you cannot do "frame accurate" editing of an h.264 because not all frames exist in an h.264 file. To be frame accurate, you have to transcode. It may be that an editor invisibly transcodes for you, behind the scenes (so to speak), into an intermediate codec, so it *seems* like you're editing every h.264 frame, but actually you're editing the intermediate codec.
tl;dr No, it does not do frame accurate editing of h.264, because there is no such thing. You can, however, transcode your source to a good intermediate codec and edit *that* with frame accuracy.
It's confusing, and I wish we video people would stop talking in "frames" but I guess it's still a useful concept..
