i've been working with grass valley hqx files exported from davinci resolve. the grass valley codec is included in resolve. i've just found it online and installed it so it is now available to vdub. until now i've been exporting proreshq from vdub but would love to keep the same format (gv-hqx) rather than having two different ones. i'm attaching two images. the first is vdub's file info page for my gv-hqx format files. the second is the pixel format window spawned from vdub's gv-hqx compression settings window. which radio box do i select to try to get a match to my original format?
fwiw, my process is to run the original through avisynth and into vdub and export from vdub.
thanks for any clues.

i just tried the 'no change' option under 'pixel format' and when trying to render it throws an error, saying that it can't 'initialize video compression.'. also, when i'm in the 'pixel format' window, the third field at the top is for 'actual output.' that says 'P016.' and, to its right, 'not supported' is displayed.
i did a little more investigating and find that, when i choose any pixel format at all that looks like it might match the original yuv422p16le (709), as reported in the info window, these selections also display as 'not supported.' the formats that seem to be supported are:
4:2:2 YCbCr (UYVY) - actual output YUYV
4:2:2 YCbCr (YUYV, YUY2) - actual output YUYV
4:2:2 planar YCbCr (YV16) - actual output YUYV
4:2:2 YCbCr HD (HDYC) - actual output YUYV
there is an option for 'other' that opens another window with many more options but that seems too long to go through here.
