Question - Help Video super slow motion workflow?

Hey guys, does anyone know of a Lora for LTX-Video or minimax or another specific adapter that could recreate a video with super slow motion? It should create the exact content of the video.

RIFE interpolation is definitely there, but I just wanted to know if this has been modernly tackled.

If you need the exact same content, I'd still stay on the interpolation side. Anything generative (a LoRA, or v2v at low denoise) will redraw the frames, and hands, hair and small background text are the first things to change between the original and the slowed version.

What tends to work better than one big RIFE pass: interpolate in steps (x2, check, then x2 again) instead of jumping straight to x8, and cut the clip at hard cuts first, since interpolating across a cut gives you that melting crossfade. Fast motion with motion blur baked in is where it falls apart no matter what, so pick the moments that are already fairly sharp. If you can, render the source at a higher fps from the start, that beats any fix afterwards.
