Hey dan850,
thanks for your reply. I know Minim quite well: that’s what I used for the video above (if it weren’t clear, I am the author).
I suspect I didn’t realize my specific question would have been quite involved, so I will give you another simpler example which elucidates the issue. Suppose you have a sketch with a system of many particles floating around, and suppose they react to the position of the mouse (for instance, they get bigger and pinker). If you try to save frames while you are moving the mouse, you’ll run into problems. Why? That’s because the saveFrame() function will reduce heavily the framerate of the sketch (in particular if you are aiming at HD quality), hence your mouse position will not be updated smoothly. One solution is the one I discuss above, i.e 1) run the sketch without saveFrame() while moving the mouse and saving for each frame the mouse position in an array which you then save to disk 2) run the sketch again with saveFrame() and substitute the mouse variable(s) with the data from the array you previously saved.
The question is not related to any specific code, but to any application that is interactive, and of which you want to make a video of. Neverthless, if you want to read some code check here

Since I find this procedure eventually cumbersome, I wanted to know what other users come up with when (if) tackling this issue.
