Testing MiniMax H3 Video Editing Workflow: Regional Inpainting & Background Swap
Altruistic_Tax1317 · reddit · 2026-08-09
A creator shared their experience editing videos with the MiniMax H3 model. The current workflow involves using SAM for region segmentation, then feeding the mask and new content into the model for localized replacement.
The author notes that while audio and video are currently tangled under the hood making proper latent masking tricky, a developer has already submitted a fix for per-region masking on GitHub. Overall, the model shows massive potential for video background swapping and regional filling.
