The YUV codec might be for exporting in DSR-DU1 format. (dlx extension)

Or maybe for the HD down rez of the HDCAM deck on capture.

I realized here in my PAL project that YUV-codec does switch the Field Order from Lower Field First to Upper Field First (same happens to some kinds of Canopus PAL dv avis and to PAL uncompressed avi). Annoying and long lasting 'bug'.
And - this codec produces a 16 bit video instead of 24 bit. Strange.

In an article by Charlie White on DNM :

We saw uncompressed footage playing right off the Vegas 5 timeline over SD-SDI at Sony's Madison, Wisconsin offices the week before NAB. It seemed to be working fine, and uses a new Sony 4:2:2 YUV codec developed specifically for this purpose.

But why uses this codec a 16 bit video instead of 24 or 32 bit?

i have used the sony YUV 4:2:2 codec to render out a DV MASTER (render) of my projects. from that MASTER i then render out dv.avi , wmv9, mpegs 1 & 2 etc.. even though my clips are dv25 the improvement is with color text and other moving titles= titles are rendered out in true 4:2:2. .. from there there is a slight improvement on color text when i make a DVD.

the YUV clips are approx 20mgs .. the strange things is when i play back a dv25 clip (5mgs) from my firewire drives they will stall after 5 min for some unexplained reason the YUV clips ( 20mgs) do NOT stall !!!

16bit video is 16 bit per channel ...
24 bit is usually 8 bit per channal
32bit is usually 8 bit per channel plus a 8 bit alpha channel

It's 16 bit per channel??? - O.k. that would explain much.
