Video Upscale

Roadmap / pending — intended AI per-frame video enlargement (2x / 4x). Run currently raises StageNotImplemented; no real backend yet.

Video Upscale · screenshot coming soon

What this node is meant to do

Video Upscale will upscale a COMFYTV_VIDEO frame by frame (like image Upscale, but for clips). scale reserves 2x / 4x. Output stays COMFYTV_VIDEO for Clip / Demux downstream.

⚠️ Current status: UI placeholder only. video_audio.py raises StageNotImplemented on Run — no fake URLs. See roadmap.md.

When to use it (once shipped)

• Enlarge low-res I2V / T2V to 1080p+
• Upscale plugin video (mesh2motion, etc.) inside ComfyTV
• Upscale before subtitle erase (also pending)

Planned design

• Same Stage + ▶ Run + snapshot model as other video stages.
• Likely a workflows/ upscale graph or hybrid PyAV + model path (TBD).
• Workaround now: Extract Frame → image Upscale → Create Video (native) → → ComfyTV Video.
