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.

Changing system

Ubuntu alongside with Windows

Old projects revisited

Occupy

Going further

Conceptual thinking vs programming

Programming language, poetry, performance, sound

connecting with writing methodologies
