Hi, this relates to the following post, but is of a different topic: http://cycling74.com/forums/topic.php?id=28955

What I am trying to do is to maintain highest quality throughout starting with the jit.qt.grab object, while creating the most efficient patch.

So if i use jit.qt.grab @colormode uyvy, I end up with half vertical resolution which ends up looking pretty poor on fullscreen output, even on a videoplane and interpolated.

If i use jit.qt.grab in argb colormode, and then use a cc.rgba2uyvy.jxs to convert to uyvy, I maintain the resolution, yet some of the compositing slab fail when the colormode is set to uyvy yet others work, so I am stumped.

I could change the jit.qt.grab @colormode uyvy and @dim 1440 480 to oversample so effectively oversampling, and the quality looks good, but it looks like it really works the cpu hard.

Am i over complicating things, or is there a bug in the colormode conversion slab, or what am i doing wrong? or am i best to stay in argb colormode for compositing and then convert to uyvy?

the original patch is in the post above.

thanks for any help in advance….
