hello
i was testing Wan2.2 TI2V 5B Hybrid Version Workflow Example form this page,
image to Video not working for me, basicly loaded image was ignored,
Comfy running in Linux latest ver. 0.60, ctrl- B to activate was not doing anything, however lines were connected full blue limage line.. so i think not the issue. No bypass i found in settings of node.

ok, Tested again, redeployed the workflow and is workign !

Works well but how do you extend the video? Wan 2.2 has a dedicated video extend section, I wonder if it's possible to do one here too

I suggest getting the example updated template for wan 2.2 from inside of ComfyUI. In that example you can set everything: length, size, FPS, etc. The workflows here are outdated.

If you upload your workflow, I can review it and see what is wrong.

With the Wan22ImageToVideoLatent node, the KSampler's preview doesn't work. It just shows a static, heavily blurred version of the input image all along the sampling process.

As far as I know, there are no working nodes or mods for video preview (I could be wrong). I use WAN practically every day and haven’t found one yet. Why? Latent safetensor sequences are not displayed in the KSampler preview, which is natively built for showing only a single render/picture (one frame, 2D).

Can it be done? I don’t think so, at least with how ComfyUI is currently coded. The preview shows the process of intermediate denoising, which is not the same as showing the final decoded render (a fully finished image).

There are alternatives you could code using the save batch → ffmpeg → gif/mp4 path. But that would consume valuable rendering resources just for the preview. Is it worth it?

Put it this way: if your rendering times are long enough that you feel you need a preview to avoid wasting time, then by definition you don’t have the resources to generate a real-time video preview. Previewing would practically double the rendering time. Why preview one video when you could just render two in the same amount of time? :)
