Progressive Scan issues
Video shot with Sony VX2100 NTSC In Vegas 7 the interlacing artifacts are horrible when there is movement—NO SURPRISE. My end product is to be desktop single file download WMV or MP4 380X285 pixel ratio = 1. I am rendering out progresive with deinterlace set for blend mode (interlace artifacts are eliminated) to a non-compressed AVI format. Overall sharpness is reduced, and that is where I need assistance.
The above settings have provided the best detail without interlace artifacts. I have never notice the softness effect when rendering progressive. Is there anyway to improve my results Much thanks for any assistance.

Work in DV AVI until you are ready for your final render. Then, render to wmv or whatever.

Gary,
Thanks for the input but I believe I am doing exactly what you you suggested. The softness I reported in my post happens when I de-interlace by rendering to progressive which I have to do BEFORE rendering to WMV or the interlaced artifacts remain with the raw footage to the WMV.
Prehpas if you could provide a bit more information in your response, I might better understand if you are suggesting that I am leaving out a step.
I would be delighted to have your insight on this issue and what exactly you were offering.

I have shot many things using a Sony VX2000 and I have never seen a problem when rendering the final edit to wmv, so I am thinking that you are making it more complicated than it needs to be.
The real question is the “artifacts” you are seeing. How are you viewing the video at that point? What are your project properties? Preview setting?

I don’t quite understand your NO SURPRISE comment above. I use the VX2100 and don’t have the artifacts you speak of during movement. The video from that camera is very sharp and clear. I have also rendered to MWV with no problems. Perhaps the problem you are having has to do with the method you are using to capture the vieo. How are you capturing the video?

All web video encodes are progresssive. You do not need to de-interlace interlaced video before going to encode for web-video – the codec will do that for you. The web-codecs will not deal well with the methods used for de-interlacing – i.e. creating an ‘artificial progressive.’ Of course, if you start with progressive footage that problem is eliminated.

Using Veags capture utility in Vegas 7. The VX2100 is connnected as a digital device leaving little room for modifications to the capture settings as far as I can see.
The resulting AVI file, the only option, is then placed on the time line and edited. During the rendering process, using the uncompressed AVI template for output file, I noticed that the “rats teeth” interlaced artifacts were present (watching the preview window during the rendering process) and was seen in the rendered file as well. Viewing the final file Windows Media Player and other players showed the same results. Using a progressive template in rendering, the artifacts were not seen. I am pretty sure that even after seeing these artifacts in the rendered, uncompressed AVI output, I dumped the file and never attempted to compress it to WMV.
Any suggestions or clues for me would be most appreciated and valued!

Gary,
Thanks for your response. I believe that I first saw the “rats teeth” artifacts in the in the preview window of Vegas during rendering. I certainly saw them in the rendered un-compressed AVI file. Playback was using Windows Media Player 9. It was pretty awful!
I did not render directly to to WMV as I wanted to experiment in this step with certain compression utilities such as Sorrenson. Seeing the “rats teeth” in the un-compressed output stopped me cold which is when I switched to a progressive rendering template.
Project properties before progressive were: standard DVD settings 720X480 lower field first, .9091 aspect ratio, best quality, motion blur Gaussian, deinterlace none, 29.970fps interlaced. These were the original settings before switching to a progressive template.
The captured video properties that vegas shows when the file is selected in the explorer view is 720X480X24,29.970fps interlaced.
Is there additional information of these settings you need that I may have overlooked regarding your question?

Much thanks for this advice. I was unaware of that and will make the adjustments to future pre-rendering efforts.
Thanks again,
Jerry
