Scene files: python file, imageMagick website

//convert all images to png or gif
$ magick *.jpg image.png
$ magick convert -delay 8 *.jpg animation.gif
* where "-delay 8" stands for 100/8 = ticks/seconds = 12.5FPS

//resize to a certain resolution
$ magick mogrify -resize 1080x1080! *.jpg
* "!"=don't take into account the original aspect ratio

//change resolution, compress and sharpen images
magick mogrify -resize 107x129! sourceImage.jpg -strip -interlace Plane -quality 60% -sharpen 0x0.1 *.jpg

//label images with their own filename and rename them using their own metadata
$ magick convert sourceImage.jpg -fill white -pointsize 50 -gravity center -annotate +0-0 '%f\n%wx%h' -set filename:base "%[basename]" "%[filename:base]_label.jpg"

//make a basic image montage
$ magick montage -label %f *.jpg montage.jpg
* useful options: -pointsize 10, -background blue, -fill red, -bordercolor black, -border 1, -geometry +0+0 (leaves no padding around images), tile=4x3

//dithering presets
$ magick convert *.jpg -normalize -dither FloydSteinberg -colors 10 output.jpg
$ magick convert *.jpg -ordered-dither o2x2 output.jpg
$ magick convert *.jpg -ordered-dither o8x8 output.jpg

//canny edge detection
$ magick convert *.png -sharpen 0x15 -canny 0x1+10%+30% output_canny_edges.jpg
* sharpening is optional but useful


//fmpeg
//ffmpeg extract 5 fps from video as image sequence
$ ffmpeg -i "input.mp4" -vf fps=3/1 "out-%05d.jpg"

//ffmpeg adjust resolution of footage with a good preset codac
ffmpeg -i ivideo_footage.mp4 -vf scale=1080:-1 -preset slow -crf 18 lower_resolution_video.mp4

Scene files: generate inputs, Turntable

A python script that produces a turntable from arbitrary geometry.
1- generate geometry with textures the first file.
2- generate a turntable with the second file.

Scene files: game of life

A vex script that implements Conway's Game of Life.
1- Pick your canvas size and your starting positions.
2- Render out the sequence in the ROP output node.
3- Optional processing (dithering + gif) can be done inside the PDG network.
