Description
Hi @zhuang2002 !
I tested flashvsr v1 and flashvsr v1.1 on human video, I saw some wierd flicker effect on human face and hair, Although my input video has that flicker effect, but flashvsr has degraded the quality even further!! Please let me know how can I resolve this? Is there any hyperparameter tweaking that can resolve this?
First video attached is input video , 2nd video attached is output from flashvsr,

Research direction
Start by comparing the attached input and FlashVSR output videos for the reported face and hair flicker, then review the documented inference settings for FlashVSR v1 and v1.1. Reproduce the degradation with the same human video and record the version and hyperparameters used. Done means identifying a reproducible cause or confirming which documented settings affect the flicker.
