mpeg2 and rendering

HaroldC wrote on 3/23/2006, 4:26 PM
As of yet I'm not able to capture in avi; only in mpeg2 format. Generally I wish to be able to edit the video. Normally to cut commercials from the front and backends. I save the video again in mpeg2. After the rendering the original file size is about halved. After the rendering in VMS a 1.5 movie will be about 2.5 gigs. DVDA evidently uncompresses the movie to about 4.5 gigs. The rendering process in DVDA is rather abreviated. It might only take two or three minutes. However, sometimes when I create a dvd and play it in the player there will be a considerable amount of pixilation. Does anyone have any recommendations as far as what settings should be?

Now within a month or so I expect to get the Canopus 110 external converter that some were good enough to recommend. But I'd like to be able to make some movies in the mean time.

Thanks

Vegas doesn't capture in MPEG 2, only avi. Can you specify your workflow, step by step?
Additionally, Vegas will ALWAYS recompress mpeg from the timeline, and likely can make it larger than the original in terms of file size, depending on the bitrate of the original capture.
What your description sounds like is you're capturing small mpegs, trying to make them full screen in Vegas, and this is where you're seeing the pixelation.
MPEG is a really poor editing format, and if you're starting with low resolution/low bitrate, there is not much you can do to make it better.

I'm currently capturing with Sony's GigaPocket and a TV Tuner card. (Some time in the next month or so I'll be getting the Canopus 110 Converter). Giga Pocket captures in mpeg. I open VMS and place the raw mpeg file into my timeline for editing. I cut the front and back ends off and render in mpeg 2. Like I said that give a file size of about 2.5 gigs for a hour and half movie. At that point I close VMS and open DVDA. When I make a dvd, sometimes but not everytime the final movie on the dvd will be heavily pixelated. Now the only thing that I can think of was that I was taxing system resources when I rendered in VMS. This is my only computer at home. My security features are always running.
