I'm thinking that sometimes limiting fps could be very useful , not for Gpu use but for an artistic approch( especially with trails and some other blur and feedback ISF).
For exemple Fugio can do this with a rate control module, you can limit a 30 fps webcam to a 5 fps and that's fantastic.
Could it be possible to think about this for the video modules ? It can be useful too for the video module as this is not the same than the speed.
There is maybe an existing workaround but I miss this
Would it be practicable to have a StopFrame module similar to the Resolution module, but with temporal rather than spatial resolution adjustment such that the output from the preceding modules was only rendered intermittently, saving GPU cycles?
Yes, really what you're talking about is a module that caches its input(s) so they don't have to be re-rendered in subsequent frames. I've played around with this, but there are a lot of special cases to be considered, which is why I haven't released anything. But, theoretically it is possible.
