Resolume Forum

Hello dear Resolumers,
I try to create a patch with Wire to create some effects of slow motion of a live stream captured by camera.
I think the best way is to use a Ring Buffer. Of course, the slow motion effect can't be "eternal" otherwise the Ring Buffer should have an endless size of frames.
But if I use a 240 frame buffer (that means 4 seconds, also I don't why the Buffer works with 60 fps and not 30...), I could make 2 seconds at 0,5 speed and 2 other seconds at 1,5 speed, and the live stream will follow this alternation of 2 seconds slow motion, 2 seconds high speed.
I try to make it by modifying the index of the buffer. I could double the time of a frame in the index. I guess if I have 60 fps, I could add a "-1" in the index every 1/30 of seconds. Also, that should make that every frame is rode 2 times. I tried to command an Add node with a metronome at 30 hertz. But I can't command an Add node in that way.
Am I close to the solution, or am I in a total wrong way ?
Hope you find my project sexy enough to give me advices !
Best regards

Jonathan

The patch will run at composition fps, you can limit that in the composition settings. Probably the easiest with the existing buffers.

Signal type maths will run at patch/composition frame rate. If you'd create your own buffer (write-shift-delay-back to write) you could change the shift amount 0 vs 1 to set the framebuffer you want to write to.
0vs1 could be made with a counter -> mod 2, the counter could be triggered every render frame using a consistently changing signal like system time milliseconds, and Onchange.

Thank you Zoltan,
I'm not sure to have understood everything, but that will helps in the future.
