I wanted to post my WIP workflow for LTX video extension as well as interpolation with 0.9.5. It is... not a pretty-looking workflow and I invite anyone to improve upon it. It works best with very similar images and I recommend using your favorite paint program to make backgrounds identical for maximal consistency.
I have attached 3 workflows. The biggest point of progress I made on these workflows was doing a 9-frame "transition" fade between each generation. This allows you to chain and extend seamlessly while also allowing for a bit of freedom for the engine to create motion.
LTX Extend: Extend clips simply with either free-form extension or keyframe-based extension
LTX Frame Interpolation: Input images with a few added bells and whistles.
LTX Interpolation Multi: The mother workflow, allowing chaining up to 7 (or more) photos all in a single generation. Each generation has a fixed seed (which can be changed), allowing you to monitor the gens and change up the seed that just "doesn't work."
I have been playing around with one of the few LORA's for LTX (chromagraph LORA). It seems to work well and decreases the model's attempted "creativity" (which often comes across as cursed rather than creative.)
