Jitter – different Delay for different columns/rows

May 1, 2012 | 3:47 pm

Hi all,
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.

So I wanted to ask:
Is there an efficient way to do that?
Or even an external or similar, that could be used for that?
Or can you do that with

Any help is welcome!!

Thanks a lot,

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

Hi Micron,
thanks for the hint.
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.

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…. ?

Hi micron,
variable would bet better,
but fixed would also be something already

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
than put your new matrix on a videoplane

hope this can help
