My vote goes to draw loop + switch, because it's very easy to implement and flexible, but I don't know what your code looks like and what you are doing exactly. Perhaps you could zip up the code and upload it somewhere. It will focus the discussion.

Hi Amnon,

All right, I see what you mean.

Structure-wise the RecordFrames is already bundled. Perhaps cleaning up the sketch might be done by trying to bundle as much of the other stuff as possible in another "GifMakerInterface" class (I don't mean a Java interface, just interface as in the type of functionality) since it concerns mainly the controlP5 controls, the dropping (although a dropEvent might need to remain in the main sketch) and the showing of the filenames etc. When it's in such a class, then your global vars, setup() and draw() and all the corresponding functions would be cleaned up a lot in the sense that they will be hidden under the hood of the class. So in the end in the main sketch ideally would look something like this:

1. // import libraries
   
2. GifMakerInterface myMaker;
3. 
   
4. void setup() {
5.   size(400,540);
6.   myMaker = new GifMakerInterface(this);
7. }
8. 
   
9. void draw() {
10.   myMaker.run();
11. }
12. 
    
13. // and have two other tabs with the GifMakerInterface and RecordFrames classes

Hi Amnon,
