Video file to gif animation

ffmpeg can create gif from mp4/mpeg file, but create low quality, for resolve this we need to create a palette for increase quality.

Create palette colors
$ffmpeg -i file.mpeg -vf fps=15,scale=-1:-1:flags=lanczos,palettegen  palette.png

Use palette for create gif from complete mp4 file
$ffmpeg -i file.mp4 -i palette.png -filter_complex "fps=15,scale=-1:-1:flags=lanczos[x];[x][1:v]paletteuse" out_full.gif

Use palette for create gif from mp4 file (from 0:55 and 9seconds)
$ffmpeg -ss 0:55 -t 9 -i file.mp4 -i palette.png -filter_complex "fps=15,scale=-1:-1:flags=lanczos[x];[x][1:v]paletteuse" out_fraction.gif

Without palette
$ffmpeg -i imagebind.mp4  -r 10 -f image2pipe -vcodec ppm - | convert -delay 5 -loop 0 - imagebind.gif


Convert png files list to mp4 (two ways)

$avconv -r 20 -i buffer/plot%d.png -b:v 4000k animation_h1.mp4

$ffmpeg -i buffer/plot%d.png -r 20 -b 4M animation_h2.mp4

Convert jpg files into mp4
$ffmpeg -framerate 1 -i frames/f%d.jpg -r 2 -pix_fmt yuv420p video.mp4
$ffmpeg -framerate 10 -i Dragon.%04d.png -r 2 -pix_fmt yuv420p video.mp4



Cut/Extract video fraction same quality no filter/codec
$ffmpeg -ss 3:19 -t 4 -i Moana_WaterFX.mp4 -vcodec copy -acodec copy Moana_f3.mp4

Convert mp4 to gif using palette and resizing
$ffmpeg -i psplat2_4k.mp4 -i palette_psplat2_4k.png -filter_complex "fps=15,scale=-1:-1:flags=lanczos[x];[x][1:v]paletteuse" -s 346x264 psplat2_4k.gif

$ffmpeg -i fluidhoudini.mp4 -i palette.png -filter_complex "fps=15,scale=-1:-1:flags=lanczos[x];[x][1:v]paletteuse" -s 640x480 fluidhoudini_palette_640.gif



Crop image video
To crop a 528×336 section, starting from position (264, 30):

ffmpeg -i first_256.mp4 -filter:v "crop=528:336:264:30" -c:a copy first_256_crop.mp4 
#ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4
