Render to AVI or MPEG2

dpetto wrote on 10/12/2005, 7:07 AM
I'm relatively new at all this and a bit confused. I use Nero to create my dvd's (menu's,burning etc.). I use Vegas 5 for my editing. Do I want to render AVI or MPEG2 files from Vegas? In the past I have done both, but obviously I want to have the best quality possible. When I use AVI files in Nero, is the encoding done in Nero from AVI to MPEG2 giving me less quality than having Vegas encode an MPEG2? Also if I use Vegas created MPEG2 files in Nero instead of AVI files does Nero re-encode my Vegas created MPEG2 files thus causing less quality? Is there a totally other workflow I should be using?

Thanks, Any help would be much appreciated.
Dave

You will get better quality by rendering an MPEG2 file directly from Vegas because you avoid the extra render to AVI. You should be sure that your render is compliant with whatever Nero expects. Any of the DVD templates should work but I don’t use Nero so you would have to check and see.

I didn't know that? So, does Vegas prepare the unrendered project first? Does it make any files . .or does it some how just ship 'em off .. bit like Frameserver does, to the MPEGing? If it doesn't, and hence the bit about AVI quality, what does it do? Interesting . . . I've been creating interim AVIs for my MPEG encoding. Thioygh it would make things more fall-over proof!

Render your MPEG-2's in Vegas, as others have advised.

You should have no trouble having NERO directly accepting your MPEG-2's prepared by Vegas 5.0

Craig Campbell of Nero's USA tech support said back in Jan 2005 :

"Nero Vision will check the source MPEG-2 file to confirm it is MPEG-2/DVD Compliant, if it's not, then it will automatically Re-Encode the file to make it compliant.

We did find that some MPEG-2 files created by TMPGEnc and DivX were not being properly recognized by our software as being compliant, and we are taking steps to address this. We have already made some improvements in this area in the current build of NVE 3.0.1.18 posted on our website. .........

We are continuing to ask customers to provide us with information about any MPEG-2 files that are not being properly detected by our software, and what program created it so that we can insure compatibility between the programs. "

(NERO has released a complete new Suite #7 this week.)

If you create straight to MPEG, you get a slight improvement in quality. Not so much in the video if it is already an AVI, but with any titles or graphics. A title is created as an uncompressed video file. If you render to AVI, you are going from the Uncompressed file and then compressing it to AVI.

If you go straight to MPEG, you are rendering from the Uncompressed file to the compressed MPEG. Thus the graphic is only getting compressed once.
