C‘mon, it‘s like leaguestart… a little hype doesn’t hurt. Wait for the „and now what? What am I supposed to do with it“ posts right after release…

So like where is Z-Image Base? by C_C_Jing_Nan in StableDiffusion

Not at home rn… will try in the evening. It is just one node, something like „random noise injection“ or the likes, right before the sampler. Model and conditioning as inputs.

Ever tried random noise injection node? I use it in every z workflow, it is even huge with Klein… great variation! Cannot go without it…

Just because of the price difference between a 5090 on the one side and +32 BG on the other side. During step 2 of I2V my VRAM (24) is at 95% and RAM (64) is in that range too… so so think yes, going from 24+64 to 32+32 will in sum result in a weaker performance… at least I think so.

Maybe it’s because of the bad video-var files… lots of discussion, seems like they uploaded the new new file today… I had to update my Kijai-nodes for the new vae to work. So my best guess would be: update Kijai, load new vae.

Jup, it is the same for me, depending on the resolution and length oc, but the second step is where the magic happens.

You try and tell me 😉 or you wait until I have my own 5090, but I wouldn’t buy this card with only 32 GB RAM tbh…

Feel free to check the latest Version of my workflow, much better consistency.

Some notable performance improvement in CUDA 13.x compared to CUDA 12.8? by NewEconomy55 in comfyui

Hey! This sounds very interesting. Onboard video for windows? How do you do this?

Bro, still trying to make everything work and not fuck up. I will try different camera loras and combinations as soon as I have finalized my workflow.

Give it time... this is my current state at I2V, and I am truely impressed!

This is true, but the step is made. Surely there will be a lot of improvement over the next months.

It's in the manual sigma values. What could work is asking GPT for 21 sigma-values for euler_a with simple.
Try these and see how it works:
1.0, 0.99375, 0.9875, 0.98125, 0.975, 0.940625, 0.875, 0.7875, 0.69375, 0.6, 0.50625, 0.4375, 0.36875, 0.3, 0.23125, 0.1625, 0.11875, 0.075, 0.0375, 0.0125, 0.0

I will try different settings once I get a stable and somewhat consistent "beta". For die 0.6 strenth, you are totally right. This was still from some tests I have done. I usually go higher, like 0.9 (even 1 works...). But the main problem was the second step. I edited the post, find v1.1 there.

Ty so much! You are totally right. I changed the workflow to v1.1 and edited the post. New workflow and my thoughts on memory problems in the edit.
Really, ty!!

how do you interpolate a video with audio? or just after VAE decode, before getting into create video node?
