dear list,
I recently tried out pix_record object of Gem, running pd-39.2-extended for osx. It worked pretty fine but i could not record anything else than a video connected to a unique gemhead. i tried to mix several pixes (like moving rectangles with alpha layer) with the video using pix_mix but when recording the visual output i only get the video (without the applied 'transformations'). is that an expected behaviour?
i am not sure whether i fully understand what you mean.
i agree with you, my description is not crystal clear. imagine that there is a video in the background (fullscreen). progressively some small recatngular parts of the video are transformed (for example gets darker) and move - in order to do that i apply another gem layer on top of the video layer and insert several rectangles objects with alpha channel.
[pix_record] will _only_ record pixes. (e.g. you have to transform your "rectangles" into pix-domain; just using [rectangle] won't do)
ok, how do one make this kind of transformation?
due to the signal-flow nature of pix-processing you have to add [pix_record] after all pix-processing objects you want to have an effect on the recorded video.
e.g.
[pix_video] | [pix_gain] | [pix_record] | [pix_invert]
will record a video with [pix_gain] applied, but [pix_invert] is NOT applied.
ok, i think i got this one but what about pix_mix?
cordially, vincent
