I'm experimenting with databending/glitching images and videos as part of a master's class. I've used Audacity to do most of it thus far, but it isn't as successful with video.

I want to try to edit video by changing the source codecs in ffmpeg, but I don't want to inadvertently destroy my current install.

Is it possible to install a second instance of ffmpeg to run independently for experimentation purposes?

If so, what Terminal command would I use to create a second, executable directory?

  • This is not very clear. Do you mean to compile a modified version of ffmpeg ? If so, you can just rename the executable into my-ffmpeg, or something. – SirDarius Sep 18 '14 at 16:53
  • which OS are you on? – rogerdpack Sep 18 '14 at 16:53
  • OSX 10.9. Sorry...should have put that in the question. @SirDarius I need to change the source (the h.264 source, ex), which is why I'm making sure I know what I'm doing. Will renaming the executable create a copy of the sources as well? (I hope this makes sense...) – Brian Sep 18 '14 at 16:57

    No. You download the ffmpeg source code, and the source code of its dependencies, like libx264, compile the whole thing. You're gonna obtain a shiny new `ffmpeg` binary which you can then rename to your liking. – SirDarius Sep 18 '14 at 16:59

    As for image glitching some of the examples in [How to create video and audio noise with `ffmpeg`](http://stackoverflow.com/a/15795112/1109017) may interest you. – llogan Sep 18 '14 at 17:05
