MPEG2 and vob

Ok I know this is SVCD forum and I've just made the step up to DVD.

Capture regime is ATI card-HuffYUV-ULEAD-Frame serve to CCE.SonicMyDVD and Philips DVD +R/+RW.

I've just dumped Pinnacle DC10 as it uses crap MJPEG compression. Tried Morgan but didn't improve that much as capture is hardware MJPEG.

Anyway, the point.

I encode to elementary streams m2v and wav.

Now do they end up as vob streams using Sonic MyDVD?

Does it do any further processing to degrade quality?

Would I be better with system MPEG2 files?

Nope - there's change in image quaity.

>>Would I be better with system MPEG2 files?

Use whichever loads fastest into your authoring app. (For example, SpruceUp loads elementary streams MUCH faster than system files).

Sorry that last post was meant to say "...there's NO change...."

If you get tired of messing with HUFF compression, you may want to try PicVideo MJPEG. I know that you just got away from it, but it really is pretty high qulaity and considerabley easier to capture/edit with.

I'm using Dc10+ with PicVideo's codec and
with the quality settings of 19/20 works
fine for me. Much better quality captures
that with Pinnacle's own codec.

I understand that MJPEG is lossy.

HuffYUV is lossless?

That's why I whent that way.

I think huffy is lossy...even if it is advertised as not being lossy.
I think a good way of looking at it is if the video is being compressed with a codec then you will experience "loss". That is in part how codecs work to get the job done faster and with less space.

Think about if you were at work and your boss told you that he wanted your job done faster and in half the time. What would you do to accomplish that? First, be more efficient, and secondly do it faster and cut corners.

I think the closest, if not the only non-loss way of capturing, is by capturing with RAW AVI. But, you will need a HUGE hard drive and a fast CPU to do this.

I have a 1.67GHz cpu and with VDUB I can capture with Raw AVI at a Res of 480x480, but on a 80GB hard drive I can only get 1.5 hours of capturing. And how's the quality? The quality is better then capturing with huffy.
