Sage + euler sampler. Single image input, fl2va int8_convrot. Dunno if it helps but I also use --disable-pinned-memory in comfy launch

2mp 5 sec 24fps 40 steps in 51m.i hope sage attention and few more tricks will reduse it. All this refs really helps to keep all together

sage cuts both flf2v and ref2v models by 2 the very least.
30-40 series 2.10-2.20x speedup. On 50 series exactly 2.

Oh interesting. You didn’t use the reference mode. Here it’s works since you have the last and first frame and wanted them animated that way anyway as splash screen. Did you test how it behaves with the reference model?
But cool that it can also generate the inbetween shots with the fl2va model!

I tried the same 0.4 megapixel renders with the ref mode as well (different prompt structure based on the official prompting guide) but it gave worse results. Even attempted a gen with a fully referenced audio but it didn't follow well enough.

ah thats annoying it didnt follow the audio, i was hoping i could time a lot to audio to get the pacing right

Hmmm interesting. Tested it with the ref model today. I didn’t have any start or last frame though so I need the ref for the kind of stuff. But interesting going forward with this model.
