  For Douglas Spotted Eagle

  Hi Douglas

  I own an EX1 and it is a stunning camera for the price.

  However, I find that when I create SD DVDs from the high def footage, it doesn’t look so good. Straight lines such as a wall or a roof tend to have very jaggedy edges when viewed back as MPEG2.

  In Vegas 8.0b, I keep my project properties at HD and I render (at BEST quality) to the DVDA MPEG2 template. Importing to DVDA obviously doesn’t require re-rendering of the MPEGS. This has been my workflow for years and it works fine.

  I have tried outputting uncompressed AVI and then rendering to 720×576 (I’m in PAL land) via two different third party MPEG encoders but this doesn’t make any difference.

  If you have a recommended workflow for creating high quality SD DVDs via Vegas and DVDA from HD footage, I would love to hear it.

  thanks in advance
  Keith

  You might try adding .01 Gaussian Blur to the final render. Sounds like you’re getting some interlace error? Are you shooting P or I?
  Best likely isn’t helping you either.
  Can you post a still?

  Thanks for the reply.

  Here is a still from the original HD footage at 1440 by 1080.

  Here is a still of the rescaled to 720 by 576.

  Please view both at actual 100% size to see the difference.

  I will try the gaussian blur as you suggest.

  Also, I am shooting interlaced.

  Interesting that you say that rendering at “BEST” may cause problems. I’d like if you could elaborate on that one! I thought that “BEST” uses Bicubic resizing?

  Thanks for your help!

  Pardon me for jumping in. I’ve finally started trying other solutions to down-rezzing HD for SD. I’ve had very good success with rendering to an HD intermediate format like Cineform, than down-rezzing to SD in VirtualDub. VDub has a resize filter with several different algorithms, including Lanczos, which work very well. There is also a free plugin for VDub that deflickers very well, called MSU_deflicker. After dowrezzing, TMPGenc is a very good transcoder to MPEG2 for DVD production. Deinterlacing as soon as possible in the process avoids a plethora of field order errors.

  Even tho’ the workflow is somewhat choppy, the overall render time is a lot faster than Vegas.
