Challenge: create traces from birds footage

Hi!

I have an idea for a video involving footage manipulation that I know how to make manually in PremierePro, but it is very time-consuming. I've always wanted to learn how to program in Processing and I thought this might be a good opportunity to get started. I'm a complete beginner so be kind there :)

Essentially what I would like to do is to get a piece of footage (say shot in 25 frames per second), extract each frame into a still picture and overlay with a blending mode of Lighten. The final effect is that you see moving objects in the shot creating traces.
Any pointer to how I may go about doing this?

By the way, any suggestions of tutorial to learn how to manipulate footage in Processing is much welcome!

Cheers,
Diego

L’issue non indica alcun file del repository, test o punto di ingresso. Inizia chiarendo come Processing dovrebbe gestire filmati a 25 fps, estrarre fotogrammi fissi e applicare un Lighten blend; il lavoro sarebbe completato con un approccio o tutorial documentato e riproducibile per creare tracce di oggetti in movimento.
