Extending Video & Color Consistency: ComfyUI Workflow Details
Dependent_Revenue_16 · reddit · 2026-08-09
The author shares an advanced workflow for generating AI video, focusing on maintaining color and audio consistency when extending video clips.
Key Technical Details:
- Extension & Transition: Uses a reference-to-video model, substituting the starting latent with the last few seconds of the prior clip. The initial seconds are masked to prevent audio gaps, while new prompts and low-res references guide the composition.
- Prompt Iteration & Upscaling: The first pass uses low resolution (480p, 20 steps) to quickly refine the prompt. The second pass upscales to 720p (0.75 denoise, 8 steps) via decode -> lanczos upscale -> re-encode to remove artifacts while preserving structure.
On an RTX 5090, generating an 18-20 second clip takes about 10 minutes.
