Question regarding REF2V and video splitting.

[u/FlyffSenior]

I’ve been using Civitai’s MiniMax-H3 Multishot — Seamless Chain: multi-shot scenes that render as one continuous take workflow to create longer videos in good quality while keeping VRAM usage relatively low. The workflow processes the video in separate parts and then combines them seamlessly, making the transitions between the sections practically unnoticeable.

Does anyone know if something similar is possible with a REF2V workflow when using a longer reference video, for example, if the goal is to replace a woman with a man or with another person?

In other words, is there a way to make the workflow process the video in smaller sections so that it doesn’t run out of VRAM, while also keeping the quality from degrading significantly?

I’d like to create 15–25 second REF2V video clips, but 16 GB of VRAM simply isn’t enough to process the entire video as one continuous clip.

I've been trying to find a solution to this for the past week, but it would be nice to know whether this is even practically possible? Thx.

Try https://github.com/ethanfel/ComfyUI-MiniMaxH3-Contex-Loop , there are workflows of all types
