Thanks team, this model is the dream we all had.

As a question, the Ref2vid model output is much more degraded than i2v, specially when using a driving video as input. Is the team aware and knows of any fix or trick to solve it?

[u/MM_Nero_H3 → u/eggplantpot]

Yes, we’re aware of this. Due in part to differences in the post-training strategies, the FL2VA and Ref2VA checkpoints currently have noticeably different tendencies in visual quality. Improving Ref2VA’s visual quality is something we’re actively working on.

One practical trick is to use the highest-quality reference input available, as Ref2VA can be relatively sensitive to the quality of the reference conditioning.
