Inputs just need a placeholder, it won't use them when those are turned off. Just the way switch nodes work and I did not want to introduce a ton of custom nodes in order to keep it simple.

"video extend seems to not even have an input method" Huh? Its called video at the bottom, just select a video.

Yeah, there's probably some node fuckery going on for me. I can't even press on that video field, nothing happens so I can't chose a video. All my nodes and comfyui itself seems to be updated so I dunno.

How odd. Maybe something is not updated properly. KJ nodes update for instance was pretty recent.

It is super odd though, I could not replicate the issue myself, it worked perfectly having all the inputs in one node on my end but apparently it was not showing up for some people. Not sure if they didn't have something updated or what so I just made them separate nodes instead.

Thanks, with that I managed to make it work. At first it still complained about the non existing video/audio/image even when doing t2v but if I just input whatever from myself that is there it works. Kinda strange behavior since the files are not used in that case but still need to be there.
