in my patch i inserted a vizzie connected to the webcam to have a distortion effect in the video. Unfortunately when the video plays it is stretched. Where am I wrong? Do you have any advice? Attached is a photo of the problem. Thank you!

solution-to-video-stretching

if you are mixing aspect ratios (as you are in your patch, 4:3 vs 16:9) then you have to decide how to reconcile that. 2 possible solutions are distorting the input to match the output (jit.gl.videoplane @transform_reset 2) or preserving the aspect ratio of the input via "letterboxing" (jit.gl.layer default behavior).

if preserving an aspect ratio of an input source in a complex patch you have to decide where this conversion should happen, usually right before the output, or right before a discrepancy (e.g. a jit.gl.pix with input sources of differing aspect ratios).

the easiest way to force this conversion "mid-stream" is to use a capturing jit.gl.node.

the final caveat is if a jit.gl.node has a dimension override (@adapt 0) that forces an aspect ratio different from its parent context, you should add a jit.gl.camera to that jit.gl.node sub-context.

the easiest way to force this conversion "mid-stream" is to use a capturing jit.gl.node. 

This is my patch. Could you make me understand here how I should intervene? Thank you very much.
