I am attempting derive a scaled 1440:1080 image from a windowed 1920:1440 portion of a larger file. The windowing is working fine by itself but when I then add the scaling switch it seems to break R2CF every time. I suspect I'm doing something terribly wrong:

r2cf A093_C021_0925EK_001.R3D SeqLeftRAW.avi -o100 -w1440 -h1080 -r -(0,534,1920,1974)

Yes, terribly wrong. :)

The little '-r' is killing it. Raw (-r) can't be scaled, once scaled it is no longer raw. You need to encode the result as 422 or 444. Remove the -r and it will work.

Got it - makes sense. Many thanks
