I have been trying to do one thing, and couldn't really get it to work well and efficiantly.

I would like to have a delay on a video (like matrixset), but, with a variable / different delay for each column or row. So let's say the first column has the delay 0, the seconds one a delay of 2 and so on (let's say up to a delay of 50 frames).

I tried taking sub-matrixes of the original video (with 1 pixel width), then put it through a matrixset, and then draw it on a videoplane - and that in a poly for each column.

This is extremely slow and creates a lot of errors in the plane drawings for some reason.

Or even an external or similar, that could be used for that?

Hi all,

So I wanted to ask:
Is there an efficient way to do that?

Or can you do that with jit.gl.pix?

Did you search in the forum and on Google for "slitscan", I remember someone made this patch before.

This is close to what I plan to do, but not the same.

With slitscan you only got one column (of some width) that is changed each frame - I want to update all the columns each time, and keep the position as it is is.

Hi Micron,
thanks for the hint.

Ok, do your columns should have a fixed progressive delay as 0-2-4-6-8 etc...

or a variable delay 8-5-0-2-9-etc.... ?


but fixed would also be something already

Hi micron,
variable would bet better,

I think you can put 50 frame into a matrix set

than you can create your image using "output $1" command of matrix set

and dstdimstart dstdimend message to matrix for each column
