filename: C.mp4
split(s): 4
It is highly recommended to input video with size around 1920x1080
High resolution slows down the entire process.
1. create directories
Following sub-directories will be created:
meteor_scan
├── dump
│ └── ...
├── output
│ └── ...
└── scanned
└── ...
2. extract video to images
clean up the previous extraction [y/N] ? y
2.1. convert video to 8 fps with ffmpeg
2.2. dump video to images with ffmpeg
3. find sky background
Processed Image saved successfuly in your current working directory.
4. detect following 4 split(s) in parallel
