VV3 & SVCD Quality

Reanimator wrote on 12/1/2001, 2:37 AM
Just did some footage and compared it to TMG. The results were fairly close. VV3 had good clarity, no viewable artifacts with motion. All in all not bad. My only observable difference was that TMG seemed to have better color & depth. The VV3 mpg seemed a little washed out. When you compare it to some of the other garbage out there ( Ligos )VV3 is way ahead. Great job guys. Perhaps my frame serving days are over...)

I agree that on first examination, the SVCD results look good. I also agree with your comments regarding the slightly washed out effect. I tried applying some of the Vegas filters that seemed to improve things at the expense of longer render times. What I would like to see is more leeway in the bitrate settings. There's no way I can get a 53 minute show on one disc with the settings available now. Any chance of an update SF or MC?

Thanks and congratulations on what looks like a great product.

To fit a 53 minute show on one disc, reduce the variable bitrates on the video page and then click the system bitrate auto-calculate check box on the system page.

Thanks very much indeed. Every time I had tried to change the numbers they just jumped back to the defaults but I had missed the system bitrate auto calc.
Excellent help!

Here's a follow up question:

Can you use the method specified above to also alter the bitrate in a VCD to make a so called XVCD at let's say 1700 kilo bits/sec?

I tried and even when the auto calc button is selected, I still can't input 1,700,000 into the variable bitrate windows.

Any ideas?

Thanks very much...

The maximum bitrate for VCD is 1,151,929 bps. That's why you're not able to increase the bitrate to 1,700,000 bps. We do not support making XVCDs.

Yes, I had a feeling that you were going to say that. I tried to render an SVCD of a 52 minute program with the HSL and Sharpen filters selected and when the clock for the render time reached 9 hours (you know it counts up before it starts to count down), I gave up and rendered it as a VCD (3.5 hours). Is MPEG 2 encoding supposed to take that much longer than MPEG 1?

Thanks very much for your answers, they are much appreciated.

MPEG encoding is time consuming, there is no doubt.

DVD rendering from DV footage is much faster than rendering same to SVCD- we have specifically optimized Vegas for DVD output.
