jit.gl.slab @file tr.edgeblend.jxs messes up uyvy colors

February 26, 2014 | 2:37 pm

Hi,

I wanted to turn my videos to uyvy due to performance optimization. But unfortunately, the "jit.gl.slab @file tr.edgeblend.jxs" object somehow messes up my colors and I can’t transform them back to rgba.

Does anyone have an idea how to fix this? I guess I forgot an attribute that I don’t know… I attached a simple test-patcher to show you my problem. And does someone have some more ideas and tricks for performance optimization of video playback? In the end I guess I will use the HAP-codec.

Thank you very much in advance!

Maxi

the edgeblend slab should go AFTER the uyvy conversion slab.

convert to rgb immediately after the output from qt.movie.
you should also set @dimscale 2 1 on your uyvy conversion slab
