HDV workflow in Vegas

John L. Miller · June 2nd, 2007, 07:40 PM

After rendering the file in Vegas, I can see these artifacts if I open the file and play in windows media player. The problem is not in DVD architect. It is definitely in the rendering. Possibly in the resizing, I do not know.

What I don't understand is how is it possible for vegas to have this issue when it is such a basic component of what most vegas users need? What concerns me is that I saw this issue once or twice but it has seemed to completely disapear mostly on it's own and my DVD's made with Vegas look spectacular.

I have watched the HDV section of Vegas training DVDs to try and pick up the workflow they use to convert HDV to SD. They use the batch render under scripts to do the rendering. No adjustments available, just use the template they provide. I am testing this now but I doubt my results will be any better. However, I did find that once each clip is captured, you can open the properties for that clip and there you have an option to click "reduce interlace flicker" for the clip itself. I have not tried that yet, but plan to. I captured some clips today using 1080 60i, 1080 30f and 1080 24f for comparison. According to Vegas training DVDs, they claim a great result capturing 60i and then choosing a widescreen 24P DVD architect template for rendering (converting 60i hi def to 24p sd). I am going to try this also. I will post findings from all my different workflows. J

The best results seem to stem from shooting in 1080 60i and converting to 24p in the render. The lines are all but completely gone. I got good results shooting in 30F with my Canon A1 and rendering in 29.976P. When shooting anything other than the 1080 60i, I have to use the "reduce interlace flicker" in DVD architect to get rid of 95 percent of the lines. No way around it. I am shocked at how good the 1080 60i converts to 24P rendering from VEGAS. It was the cleanest of the clean. It really looks nothing like 60i when it finishes. I am doing more testing to make sure that is my preferred workflow. I am still working with the 30F and rendering to 30P. At this point, I do not like the 24F if you are going to have any motion. Too hard on the eyes. Until further testing changes my mind, I will either shoot the 60i so I can turn it into whatever I want in rendering, or shoot the 30F. Not sure yet. Though 60i by itself is UGLY. But using it as the base and rendering to 24P gave me very clean results, cleaner than shooting in 24F. J The testing I am doing right now is upping the bit rates on 30P and also from 60i to 24P to see what happens!
