MiniMax H3 Test: Powerful Video Generation but Fails at Face Swapping
xDFINx · reddit · 2026-08-11
A user testing the MiniMax H3 model found that while it is incredibly powerful and easy to use for most video generation tasks, it struggles with the specific need of character/face swapping.
The author attempted to swap a face from a reference photo onto a reference video but found the model usually only extracts attributes from the photo rather than performing a true face swap. Simple prompts, complex instructions, and following the official prompt guide all failed to resolve the issue.
