Rendering a Multiscreenvideo

vvvv beta question
1

Hi Everyone,

I wanted to ask if anyone got experience on how to render a multiscreen setup to a video.

I have a patch which plays on a triplehead 3x1280x1024. The Output looks really great and i would like to capture this output and render it to a video the same size.

I tried the Writer-Texture NRT Node, because it seems that it captures the output frame by frame and no frames get dropped. But the pictures seem to loose the Antialiasing, and also they get compressed in a certain way. The picture is not as clear as it is on the monitors.
Also the Colors get funky in the rendering process…

I add a picture of wireframe/point model where i think you can see the difference really good. left in the picture is the render window, right is the captured picture.

Thanks in advance for your answers…

Dirk

ai scarab,

the picture is missing…
Writer (EX9.Texture NRT) should be the right node for that task.
for a test please try to have the 3x1280x1024 renderer (i assume it is one wide renderer, right?) hidden but set its backbuffer width/size to the desired resolution. also hide all other renderers that may be open (to save videoram) while writing out the textures.

hi joreg,

thanks for your answer.
i’m just trying to get better results now with a 1280x1024 resolution.
attached the picture.

of course it also depends on which format you choose (jpg is really bad!)
but still i get bad results …

i keep you updated :-)

thanks

fcourse use .bmp or .png
hm…the colorchanges kind of look like there is a blend-mode missing in the rendered output that is there in the renderer.

hard to guess. can you provide a simple patch that demonstrates the problem?

what i found out until now is, that the wireframe/point Fill looks very different in the renderer. if the fillmode is solid it looks really fine.

thanks for your help. i’ve got everything i need ;-)

just for curiosity reasons: can you also write multiple renderers? each with a writer node? …
should work as well right?..

sure.
