Video Optimization Solution for Mobile
For the common problems of shaking and uneven exposure in mobile videos, Diffuman4D has built-in pre-processing modules: 1) electronic stabilization via scripts/stabilize_video.py; 2) automatic light balancing using the auto_exposure parameter; 3) support for -phone_mode Optimize mobile data. Specific implementation should: ensure that the shooting environment is well lit; use a tripod to fix the phone; turn off the automatic beauty function.
workflow
- Preprocessing: run python scripts/denoise_phone.py -input your_video.mp4
- Add mobile optimization markup when generating: python generate_views.py -phone_opt
- Enabling the -robust parameter in the rebuild phase improves fault tolerance
Shooting Suggestions
Best practices: 4K/30fps format is recommended for iPhone, 1080p/60fps for Android phones; keep the subject occupying more than 60% area of the frame; 3-5 viewpoints are recommended to be shot in a wrap-around manner, with each viewpoint lasting more than 10 seconds. You can use scripts/interpolate.py for frame rate compensation when encountering serious frame loss.
