FMF2V possible?
(Moved this from a comment on a previous discussion to its own thread.)
Is "FMF2V" a possible "thing?"
As in provide the first frame and a middle frame but NOT a "last" frame so the video continues from middle and finishes where you prompt it to?
Oh i must have missed or forgotten that post...
Yes thats entirely possible.
You could even try the First-Middle-Last frame workflow as is and just set last frame strength to zero in the LTX Image Guider node (or InPlace node in case its the frame injection workflow)
Think that might work, but i havent tested.
Will do a test asap, and if it doesnt work, make a FMF ;-)
Awesome. Didn't think to try setting frame 3 strength to 0. Trying a run like that now.

Should work... in theory.
But like any theory, its just a theory ..hehe
But give it a try ;-)
LOOKS like it's working, at least for what I was after (I think I'm mostly just seed hunting for a better result at this point). Great tip! Curious to see how it works for you.
will give it a go, but yeah should work (in theory hehe)
