Blurring during quick movement at DVinfo.net

Brian Grossman · April 10th, 2011, 07:51 PM

OK, I am pulling my hair out over an issue I am having with a sequence. I have numerous clips, both HDV and DV in a single sequence (my "show intro" sequence). The sequence itself is set to NTSC DV, Lower Field Dominance, with Compressor set to DV/DVCPRO - NTSC. This sequence is then nested into the master sequence (the "full episode" sequence), which has the same settings as the show intro. When played in the Viewer, all looks fine. I even exported to a self-contained Quicktime Movie, and it looks fine. However, when I export to Compressor using the DVD - Best Quality 90min, the resulting DVD has issues. The clips in my show intro that were originally HDV and include any type of quick movement are all "blurred" or "streaked". I've tried messing with various settings, but I can't seem to fix it. I just can't figure out why it would be fine in my exported .mov file, but have issues on the DVD. Anyone?

Brian,

Unfortunately the "best" setting in Compressor is far from actually being the best, most especially with sequences that have a lot of motion in them.

What you need to do is two things:

1. Go into your encoder tab in the Compressor setting and uncheck all the "auto" settings and force the frame-rate and field dominance to exactly what you want it to be. A "progressive" setting will yeild the best results however you'll have to decide this for yourself based on the tests you do.

2. Go into the "Frame Controls" tab and turn on the controls, set them to the same settings you see in the screen-shot.

The really bad part is that when you boost all these settings as noted the time to encode your sequence will increase exponentially, so count on letting Compressor do it's job a lot longer than before.

Let us know how this plays out for your results.
