Video length limiation?

[lumiaomiao]

Thanks for great work!

1. Did you test the limitation of video length? In inference phrase, to use Middle-frame attention guidance, all video clips of a long video need to be denoised together, so that the V[N'/2]could be generated timely. So maybe there is a video length limitation?

2. Another question about Middle-frame attention guidance: when you choose V[N'/2] as the key frame, it will be invalid if scene changed after V[N'/2], right ？

3. Is there any update on the code release?
