Problem viewing Vegas rendered video on TV
Hi everyone,
I’m having some trouble with motion on a regular TV screen. I am making a video of an interview in Vegas, and most of it is just a shot of the persons torso and face. After rendering as NTSC DV, I convert to .vob and .ifo and burn it to a DVD to watch on a regular TV. The “talking head” shots look great, but my problem occurs when the person does hand motions while talking. When the person moves their hands, the hands blur or pixelate and it looks terrible. On first viewing on the computer, it looks good. It is only after transferring it to a TV that it does this. Is there a different way of rendering or some way to change the project properties that might help to fix the problem? I thought changing the Deinterlace method or field order might fix it, but I dont know much about those functions.Any advice would be very helpful. Thanks in advance

You didn’t say exactly how you “convert to .vob”
Normally vobs are made by a DVD authoring prog, and in Vegas the render is to MPEG2, for which there are many quality variables.
Perhaps you could decribe your rendering procedure in detail …

So I choose ‘Render As’, and I’ve been rendering it as an .avi. So I choose .avi and I use the NTSC DV template. From there, I’ved clicked on ‘Custom…’ and tried changing from upper field to lower field, but both produced the same problem. After rendering it as an .avi file, I have a program that converts .avi files into .vob and automatically burns it as a DVD. Hope that gives enough info.

It sounds like the program that converts from avi to vob is introducing the artifacts – does it have quality variables – e.g. when exporting from Vegas as MPEG2 using a DVDA template, there are many ways to customise the quality, such as Rendering quality, video quality, cbr or vbr, change bitrate, double pass etc.

The program I’m using to convert .avi to .vob only has 2 options: NTSC or PAL, and the aspect ratio. I’m not sure if its that program or not, but I’ll try using a different program to convert. Is there some common way of creating video files in Vegas and burning them to DVD’s that I’m not aware of? Thanks for your help Peter.

I had a similar problem to this – and again it was particularly noticeable on hand movements. But – I had the picture reduced slightly within a border and I think it was that resize that caused the problem. Selecting “Reduce Interlace flicker” solved the problem for me.

Actually, thinking about it – it may have been “Force Resample” that I selected!

I’m not sure what options Vegas carries if you don’t also have DVDArchitect – I’ve always had both. I seem to remnember the MPEG2 encoders were licensed with DVDA but have a look – are there any options under MPEG2 in Render as?

Where are the “Reduce Interlace Flicker” or “Force Resample” options that you speak of in Vegas? It sounds like reducing interlace flicker might solve the problem. Thanks

Right click the event and choose ‘Switches’ – they’re in there.

What are you rendering the mpeg to? What size? Check the file properties and set those to match what you are going to output to. Then render the mpg file. I always use the various DVDA streams but check which one you are using. There are a bunch.
