A developer tested the MiniMax H3 Ref2VA model (paired with a 4-step Turbo LoRA) on an RTX 3090 (24GB VRAM), successfully demonstrating complex video editing capabilities.
Task: Remove a moving human character from the original video while preserving the environment and a "portal special effect."
Model Performance:
- Successfully erased the target character and reconstructed the background for the generated video.
- Demonstrated robust audio processing by generating matching ambient soundscape and automatically removing the background music from the original clip.
Execution Parameters: The original 1080p video was processed at 1376x768 resolution and 24fps. The run used a custom Turbo Sampler (4 steps) with a denoise strength of 1, taking about 44 minutes to complete.
