I encountered a critical Bink Bug:
When encoding Bink videos from full HD material (1920 x 1080, see image A) without any scaling, Bink doesn't mix the color channels correctly (i.e. shifts their on-screen position). As seen on attached image B, the encoding seems to work fine, when full HD material gets encoded/downscaled to 720p HD (1280x720). You get some of the expected blurring due to the down-scaling, but that's perfectly okay.
However, when there is no scaling involved, i.e. Original Image A: 1920x1080 encoded to Bink 1920x1080 (Image C) you get a SIGNIFICANT off-shift in the color channels. Image C demonstrates how the RED-channel is moved up on the screen, while the grey colored area remains at the proper position.
(Images are scaled to 200% for demonstration purposes)
As we need to rely on Bink with UDK, this bugs seems to be unacceptable and I'm surprised that I appear to be the first one reporting it. Will that be fixed soon? Or is there a work-around in the settings that I didn't see?
Thanks for your help in advance...
PS: I just noticed that I cannot add attachments to posts in this forum. How are users of UDK supposed to properly report bugs for a VISUAL engine, when we're not allowed to attach images? I don't get it... Anyway, I linked the image in from our webspace.
