Linux System Information

Find if your Linux is 64 bit is by using:

$getconf LONG_BIT

`uname -m` tells only about the kernel, the userspace and distro can be still 32-bit. Similarly `lscpu` only tells what the CPU is capable of, not if OS, kernel and distro are 32 or 64 bit.
 

 

$file /lib/systemd/systemd

$lscpu

$uname -i

$uname -m 

$dpkg --print-architecture

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

Recommended resolution & aspect ratios

For the default 16:9 aspect ratio, encode at these resolutions:

• 2160p: 3840x2160
• 1440p: 2560x1440
• 1080p: 1920x1080
• 720p: 1280x720
• 480p: 854x480
• 360p: 640x360
• 240p: 426x240
