img2webp: convert a sequence of images to an animated webp
...
Usage:
img2webp [file-level options] [image files...] [per-frame options...]
File-level options (only used at the start of compression):
-min_size ............ minimize size
-loop <int> .......... loop count (default: 0, = infinite loop)
-kmax <int> .......... maximum number of frame between key-frames
(0=only keyframes)
-kmin <int> .......... minimum number of frame between key-frames
(0=disable key-frames altogether)
-mixed ............... use mixed lossy/lossless automatic mode
-v ................... verbose mode
-h ................... this help
Per-frame options (only used for subsequent images input):
-d <int> ............. frame duration in ms (default: 100)
-lossless ........... use lossless mode (default)
-lossy ... ........... use lossy mode
-q <float> ........... quality
-m <int> ............. method to use
example: img2webp -loop 2 in0.png -lossy in1.jpg
-d 80 in2.tiff -o out.webp
