Hi,
Not sure if this is the right forum.
I'm trying extract information from a video (like rgb values, overall brightness etc)
But I'm not sure how to get this information or from which object to get it from.
Does anyone have any ideas? Here is the patch to load a video file
usinggem.pd

Hello. [pix_data] will get you colour information for one pixel, but you will need to bang it at the frame rate.
It is more likely that you are looking for [pix_mean_color] which will give the rgba mean values for an image, and you can then calculate a "brightness" from those values as well.
