Re: [PD] diff frame from previous frame with Gem
Your patch is pretty simple, but it seems to be that the logic of this operation should be based off of the frame clock rather than a delay. That way, the patch would work no matter the frame rate, for example. .hc On Mar 10, 2010, at 11:30 AM, Max wrote: hi hans, why so complicated? just use [pix_delay 2] and [pix_separator] to feed the [pix_diff]. 05a-difference.pd taken from http://web.uni-weimar.de/medien/wiki/Bewegungsmelder Am 03.03.2010 um 23:39 schrieb Hans-Christoph Steiner: I am trying to make a simple patch where the current video frame is [pix_diff]'ed against the previous video frame.

pix_delay actually works exactly that way. its not milliseconds, it's frames. have a look at the helppatch fo pix_delay m.

Re: [PD] diff frame from previous frame with Gem
Hi, I think I got close, but did manage to create a bizarre effect: I got just a white frame. I think you should cycle the placement of the frames in the buffer (so you always keep the last and new one) as well as first send bang then anything to the pix_film ..
