//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
ffmpeg -i KALIA4.MOV -vcodec mpeg4 -acodec ac3 -ar 48000 -ab 192k KALIA4.mp4

//put videos together
        //partly working
ffmpeg -i KALIA2A.mp4 -i KALIA2.mp4 -strict -2 -filter_complex \
"[0:v][1:v]hstack=inputs=2[v]; \
 [0:a][1:a]amerge[a]" \
-map "[v]" -map "[a]" -ac 2 together.mp4

//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.

This video was part of another project, in which I was invited to participate.

Conceptual thinking vs programming

Programming language, poetry, performance, sound
