I think I know the answer to this question, so it may be a feature request, but does anyone know of a way of keyframing the interpolation method? I have a respeed that part of it works well as a mix but other parts work well as motion. At the moment, have had to split the shot into 2, but I’d like to keep it as one shot.
I usually stack the cut up parts on the timeline so that the bottom layer stays intact. I find it’s easier to make small tweeks without screwing up the original, or to just key selected areas on top of the original.
Yeah, just seems kinda clunky, would be neater in one segment, especially if the respeed isn’t yet locked.
@paul_round - you may get some traction in batch by key framing the input source of a mux node that has two inputs.
Have you tried the machine learning timewarp in 2025?

Hi Phil, we’re still on 2023 and looking to do this in the timeline ideally.
@paul_round - does a bfx (brrrr!) get you some of the way there in the timeline?
one source, two timewarps, one multi channel MUX → output?
or do the frame numbers/timecode/keyframes get all wonky?
It’s an option I hadn’t considered, i’m not a fan of bfx. I may give it a whirl monday.
I think the BFX option is clunky. With the two layer timeline approach you have much more versatility. For instance, when you change from Mix 0 to interpolate, you often lose sync by a frame, depending on what the time warp percentage is and where the frame falls in the sequence. I keep the interpolated version on the bottom and make adjustments to the Mix 0 on the top. It’s easy to pull the handles around to make sure the top and bottom layers have a sync point and you don’t get a funny jump on the transition. You can also mask just parts of the Mix version on top of the interpolated version. You can even add a two frame dissolve at the transition point to soften the change. And all of this is on the timeline for fast, easy access and a consolidated control environment instead of bouncing from node to node in the BFX.

FWIW i do my best to avoid BFX at all costs…

I’ve been burned by BFX more times than I can count.
So like 3 times, eh? Dayum.

I do this regularly and just cut it into a segment for each interpolation method and keep a clean copy set to mix or whatever underneath in case I need to redo.
Yeah, that’s what I’ve done, just would be nice and neat to keep it all in one segment.
I think this is by design. We can’t key any multiple choice parameters, like blend modes or surface types. We just recently got the option to animate mo-blur on/off.
