When a transition is placed next to a meta strip, the meta will use the wrong strip time. It uses the strip time of the transition instead of its own.

This is the opposite of what's shown in the video. It looks like the transition is using the meta strip time. This is also consistent with the patch itself, as you're fixing the transition evaluation, and not the meta evaluation. I'll fix that in the commit message.

Thanks for accepting the fix.
About the issue, there are two ways to fix it. The other way is to change (anim_sys.c) nlastrip_evaluate_meta():
evaltime = (nes->strip_time * (strip->end - strip->start)) + strip->start;
to use nes->strip->strip_time instead.
For the transition vs metastrip confusion: Transitions will evaluate the prev and next strip through nlastrip_evaluate() and linearly blend the channels. The meta would use the transition's NlaEvalStrip strip time because tmp_nes is a copy of nes. Since the metastrip will evaluate with the wrong (and changing) transition time, then the transition will blend with the wrong (and changing) value for the next strip. I'm probably just being tedious. I appreciate the commit.
