# video-to-gif
## Usage
```
usage: video_to_gif.py [-h] [-w WIDTH] [-r FRAMERATE]
[-s {fast_bilinear,bilinear,bicubic,experimental,neighbor,area,bicublin,gauss,sinc,lanczos,spline}] [-i {none,dup,blend,mci}]
[-t TAG]
INPUT [INPUT ...]
usage: video_to_gif.py [-h] [-w WIDTH] [-r FRAMERATE] [-e] [-t TAG] INPUT [INPUT ...]
Use ffmpeg to make GIFs from videos
Use ffmpeg and gifski to make GIFs from videos
positional arguments:
INPUT input file, supports passing a glob like /Users/MyName/Videos/*.mov
options:
-h, --help show this help message and exit
-w WIDTH, --width WIDTH
width of the GIF in pixels, respecting aspect ratio (default: 960)
-r FRAMERATE, --framerate FRAMERATE
-w, --width WIDTH width of the GIF in pixels, respecting aspect ratio (default: 960)
-r, --framerate FRAMERATE
framerate of GIF (default: 12)
-s {fast_bilinear,bilinear,bicubic,experimental,neighbor,area,bicublin,gauss,sinc,lanczos,spline}, --scaler {fast_bilinear,bilinear,bicubic,experimental,neighbor,area,bicublin,gauss,sinc,lanczos,spline}
scaling algorithm to use (default: lanczos)
-i {none,dup,blend,mci}, --interpolate {none,dup,blend,mci}
interpolation method to use (default: none)
-t TAG, --tag TAG optional tag included in file name
-e, --extra increase quality at the expense of file size and encoding time
-t, --tag TAG optional tag included in file name
