Summary

Melvin Vivas reshares a demo video, saying only "wow, this is really cool." The quoted post shows VFX features added to ComfyUI: a live preview while you adjust settings, several effects chained together, changes that flow down the chain, and proxy loading for large files. The tool or extension isn't named in the material we have, and the video has no speech. It's a short showcase rather than a tutorial.

Key points

• The quoted post says ComfyUI is getting real VFX (visual effects) features right in its node workflow.
• You get a live preview while you change effect settings, so you don't have to re-run the workflow to see the result.
• You can chain several effects together, and a change to one effect carries through to the effects after it.
• Proxy loading lets you work with large media files by previewing a lighter stand-in copy.
• The goal is to stop switching between separate workflows: what you see is what you get, all in one place.
• The tool or extension shown isn't named in the caption, and the video has no narration.
