While trying to get a better (clean) render of an HDV to SD project I ran across a setting I had overlooked before and I believe it helps.
To begin with, my current PQ is very good and quite acceptable for SD. But, I kept noticing a slight degree of "frizz" on fast moving background objects. Slight, but noticeable and this in addition to the normal expected 60hz /120hz issue with LCD's!
On the Render tab, Advanced Video there is a checkbox "Allow field based motion compensation" and it is checked by default.
The help file states: "Allow field-based motion compensation
Select this check box if you want to use field- and frame-based motion prediction when predicting frames. When the check box is cleared, only frame-based motion prediction is used.
We recommend that you clear this check box if you’re creating MPEG files for NTSC or PAL DVDs or SVCDs"
Note this last paragraph... it would appear that the default checked condition is not correct for DVD production.
I unchecked the box, did a two pass encode and I believe the video looks cleaner. Not dramatically, but anything is good!
