The author ran a discovery test with Claude on H3 video generation after teaching Claude to operate ComfyUI on a home server.
- Hardware setup: a 5080 16GB GPU backed by 192GB RAM.
- Workflow: used the prompting guide plus default ComfyUI i2v settings.
- Output: generated a short story sequence in multiple clips, then a 15-second video to finish the story.
- Performance notes: about 15 minutes per 5 seconds at 1504×832, with upscale via an NVIDIA RTX node.
- For the longer clip, resolution was reduced to 1152×640.
- The author’s takeaway: Claude had no problem picking up H3, and the first impression is very positive.
