picture shimmers during motion in finished DVD
Hi all –
Now that I have the basics on how to author a DVD in Encore (thanks everyone!)
(Export from Premiere as Mpeg 2 DVD, 2 pass VBR, Minimum=2mbps, Target=4.4 mbps)I have an odd issue that showed up in the finished DVD.
We are editing a song/dance concert.
In the playback in the camera, Premiere or Encore, everything plays smoothly.When I build the DVD, any video that has fast movement (dancing) has a “shimmer” to the motion, and any footage with someone standing and singing or moving slowly is crystal clear.
Source footage was shot with a Sony DCR-VX2100, tripodded. Captured into Premiere, rendered using the settings above as MPEG2, pulled into Encore to build the DVD.
Machine is a Dell XPS Gen 3.2 Ghz with 3 Gbs of RAM

You did not mention what your “Maximum” bitrate nor your “Quality” setting was, but I suspect that the high motion content of your event precludes the encoder saving very many bits during the still scenes (minimum bitrate) to help during the high motion (Maximum bitrate). This leaves you with pretty much a 4.4 mbps action video, a recipe for what you are seeing.
Suggest either 2 disc set at 8 mbps cbr or use a dual layer disc. -
Sounds like it could be a field interlacing issue. You have to be sure to encode your .m2v files with the proper field order.

hi jeff-
what is field order?
thanks!

My experience with reversed field order is that the video looks strobed during motion or camera panning but just fine when thing are still.
Low bitrate causes mosquito noises and blurring during motion.
Would be nice if we could all SEE what we are discussing. Can you email me a frame grab? velte AT coxDOTnet -
