//merge videos
To merge files together using ffmpeg:
    1. make a textfile.txt with the list of files you want to merge:
        
file '1.mp4'
file '2.mp4'
file '3.mp4'
        
    2. Then input this command into terminal
	//doesnt work
    ffmpeg -f concat -i <textfile.txt> -c copy -fflags +genpts merged.mp4
	
	

	ffmpeg -f concat -safe 0 -i textfile.txt -c copy merged.mp4
//zoom in videos
ffmpeg -i PA190747.MOV -strict -2 -vf "scale=2*iw:-1, crop=iw/2:ih/2" KALIA2.mp4

//CONVERT

//reverse video
https://video.stackexchange.com/a/17739

ffmpeg has a reverse filter.

For video only:

ffmpeg -i /storage/emulated/0/ffvid/frameCount.mp4 -vf reverse reversed.mp4

For audio and video:

ffmpeg -i KALIA1.mp4 -strict -2 -vf reverse -af areverse reversed.mp4

This filter buffers the entire clip. For larger files, segment the file, reverse each segment and then concat the reversed segments.

Changing my life/system

Ubuntu alongside with Windows

Old projects revisited

Occupy

Conceptual thinking vs programming

Programming language, poetry, performance, sound

different experiments with videos, python using raspberry pi as a tool for organising, documenting, communicating some wiki skills

Local networks, media hacking
