capture in aviformat

Hello, I am new here and I have a big question:
I capture my videofilms in AVI format, and I render it in mpeg2.
When I make a dvd with menu and several films (the dvd is about 4.7 GB), the time to render and brand is more than 7 houres. I make my films in pal-widescreen and I use dolby surround 5.1
Is that normal that it's take 7 houres? Or what do I wrong?

Render and burn time depends on my factors including the performance of your PC, hard drives, DVD burner and media, size of AVI, render quality, amount and complexity of FX, number of tracks, opacity, etc. Seven hours is not unheard of. I've gone over 7 hours render time for a 58 minute AVI to MPEG-2.

Hello, Marie-Lein! Although I don't use PAL, the idea is still the same. The two factors that determine render time is processing power and how many "alterations" have been made to the video. The more effects you add, the longer it will take. So a 7-hour render for a 4.7GB DVD is not uncommon.

here's a better/worse case for you...
Rendering a 3D background for a DVD menu consisting of 8 tracks of video, several 3D, heavy motion blur, heavy noise reduction, light rays, supersampling on 4 tracks of vid, no audio...
20 seconds of video took 8:25 hours to render. Blurs, opacity, these all take huge hits on processor speed and resampling of video.

Spot,

Wow! That's about 1,500 to one render time, and I bet you were using a pretty decent machine.

Seems like Vegas is not doing those things optimally. If each step were done sequentially (it may not be possible, of course), would it have even been close to that total duration?

Thanks everybody for your answers, so I have a new question: isn't there in vegas a possibility that you can capture in mpeg2?

No, not to my knowledge. It always captures as an .avi file. To capture as an mpeg2 that would require compression on the fly (or compression as it is capturing). Now that would be slow!

You can't do it directly in Vegas, but there are some very good MPEG-2 capture cards out there that could be used to do a direct capture to MPEG-2. IT would work great as long as you don't plan to edit the files after you capture them, otherwise you will see a big quality loss.

Here are a few from Canopus
