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.

that's not very surprising: the same thing would happen to messages and DSP. (well, I'm surprised by the phrase "signal flow": what does it mean?)

what's a lot more surprising is that

[pix_video]
 |
[pix_gain]
 |
[t a a]
 |   |
 |  [pix_invert]
 |
[pix_record]

actually applies [pix_invert], because gem messages handle pix (and all the other state) by pointer, so that the pix seemingly sent from [pix_gain] to [pix_record] is actually modified although the message sent isn't modified.

This doesn't necessarily happen in other video plugins.
