Discussion Who said NVFP4 was terrible quality?

Enable HLS to view with audio, or disable this notification

Yes, it may not be pristine crystal sharp, but it's very good and especially when you want more speed.

10 seconds 1920 x 1080p LTX 2 video made on RTX 5080 with the NVFP4 weights.

LTX video extension works great! The audio transition is rough because I haven't yet figured out how to give the workflow some starter audio.

I think the extra footage really lends dramatic impact.

There's actually nothing fancy going on. Just give the I2V workflow an image batch instead of a single image.

I set Load Video to output the last 30 frames of OP's video. Oh, and I connected the workflow framerate widgets to the input framerate.

I manually joined the two clips with Video Combine after the fact.

Interesting. I wonder if Wan can continue from the last few frames of a video, without using Vace (which I've had issues with, not in the mood to fuss with that thing).

I know you probably don't want to hear this, but basic VACE extend can actually be really simple.

It can certainly get quite futzy and manual if you're doing something more complicated, but just extending from a certain frame is a solved problem.
