Video RGB with Delay Module on each colors is not working well...

[thomaschamotte]

Hello everyone,

I have seen on this website something i would like to do with Usine.
Follow this link to understand what i'm talking about : https://adamferriss.com/rgb4d/

So I'v created three different racks each one for each colors R, G and B.
In each racks i've added one patch who contained a "RGB module color" with a "delay data module" and a "Fit Horizontal" patch.


very very very simple and it works very well when: Delay R = 100ms; Delay G = 200ms; Delay B = 300ms.

My problem come when the delay pass up 400ms.
For exemple : Delay R= 200ms; Delay G = 400ms (this is the limit); Delay B = 800ms (everything go wrong)
The symptoms are : the fit horizontal flip, the colors flip, the vidéo stop... the RGB patches lost the datas etc...

I can't figure out why i can't go up the 400ms because on the website it works very well.

I think of the information vidéo who are not convert in a good way with the delay data, because some times the vidéo datas came in the delay but not out.
What i really don't figure out is, everything go wrong but never for the red color...

You will seriously make my day if you find why a simple thing like this seems to be complicated...

Thanks for reading.

best way to have help would be to share your workspace ?

[oli_lab]

my guess would be to decompose the signal in R, G and B, put some delays on each color channel and then recompose the video stream

Ok, there are the workspace.
Two workspace because as i said in my the last post, when you up the delay after 400ms, nothing works.

Worspace1: Delay R=0ms; Delay G=200ms; Delay B= 400ms.

Worspace1: Delay R=300ms; Delay G=600ms; Delay B= 900ms.

The idea is to use use a fader as in the website link i posted before to play with the delay.

I up the topic.
No bugs for you here ?

yes, might be wrong but i think the problem is data delay was limited in internal memory, and while buffering a simple float 400ms is ok, delaying video make load of data and it can't handle it past 400ms indeed.. maybe there would need a video delay dedicaced update or something..

[thomaschamotte]

Can you explain to me why it's working on the website follewed on the link up post and not in Usine ?

[23fx23]

i think when data delay module was designed a long time ago there wasn't video support at that time, it is not really located in video modules, it would need an update with bigger buffer, i would report as a bug or feature request, senso will probably figure a way to solve this.

You ROCK !

Hello,

I'm uping this post because the bug is always working.
And i can't continue to work on this workspace.

Thank you.

Hi thomas, did you fill a bug report for this one? if not yet you should, they can't track easily bugs on forum, they are more quicly tracked and solved if submitted.
