Need I need to do saveFrame to disk (maybe so many images )??if yes how to change it save to another folder???
and is there any better idea??
Well, if I understood correctly, yes, that's the way Processing makes movies now: save all the images to disk, then use the built-in tool (or an external tool) to make a movie out of the frames.
To save to another folder, just put the full path in the saveFrame() parameter.
is there another way save too much image seems messy .......
This is a very common way of dealing with video by professionals. Known as "image sequence". Think the folder containing the frames as your "movie" file. : ) After making a self contained movie out of this, the folder can be deleted.
It's ok, you need 20.000 or more images
