We've heard that Kijai's video_vae has been changed due to an som issues. The vae loader has also changed. The link remains the same, so please download it again.
And you also need to force update kjnode.
This is the workflow I personally use.
All necessary information is noted within the workflow.
Both T2V and I2V are possible.
It runs with similar specs to Wan2.2 in the same computer environment, same video resolution and video length.
In my computer environment,
Wan2.2-I2V-A14B-Q8_0 8step 16fps 300sec
ltx-2-19b-Distilled_Q8_0 8step euler 24fps 150sec
ltx-2-19b-Dev_Q8_0 20step euler 24fps 300sec
ltx-2-19b-Dev_Q8_0 20step res_2s 24fps 450sec
I have 24gb vram, 32gb system ram, but it runs fine with -novram, so it should work fine with 8gb vram.
If you run it with -novram, the generation time will be about twice as long.
If possible, keep your prompts as long as possible. If they're too short, errors may occur or unintended effects may be added. Be sure to include sufficient scene descriptions and dialogue.
