 Posted: Tue May 27, 2003 9:49 pm Post subject: TMPGENc disaster - IMHO |
 |
|
To narrow the discussion form the First success thread, I started this new topic.
Instead of serving the avi file directly to TMPGENC (don't have the software yet), I created a miniDV tape image from my editing and then tried to process it by TMPGENc.
I went to the web and read bunch of advices on the setting. At the BEST results setting (double pass etc) it predicted 24 hours to do the compression, I let it run for a while and interpolated the times and indeed that is what it would take.
Then I ran it at TMPGENc recommended DVD quality outut. It took over five hours !
The movie is 30 minutes. It takes about 6GBs in avi. TMPGENc result was an mpg (not a m2v) and it was only 800K - meaning it really comressed the hell out of it. The result is terrible. The added sound track is clipped all over the place, the movement is jerky, it's 100% worse then the avi to DVD process by myDVD.
Here are the the use specs:
Machine: Dual processor (Xeon PIII 2x800Mz)
Windows XP
SCSI hard drives 10000 RPM, output drive freshly formated, 32GB
input AVI in contiguous space
Considering the original films quality (certainly maintained by your scanning) I now feel that going Tape - Avi - edit - AVI - myDVD - DVD gives me the best time/price/quality result.
Will keep this going. Are you promoting this forum ?

First a couple questions:
1) Did you use the basic version of TMPGEnc or the Plus version?
2) Did you use the project wizard or choose your own settings?
So, the fact is you definitely had the wrong settings either way. Don't take this the wrong way though as it's quite complicated, and may require a lot of experimentation to get everything right. Also, audio is another matter entirely, but know that MPEG audio is not part of the DVD spec. You really should use AC3 audio, but since you probably won't want to spend the money for an encoder (unless myDVD does it for you - I doubt it). Just remember that MPEG audio may not be supported by all DVD players.
Let me see if I can help with the settings that should work best for you based on your machine specifications and DVD authoring:

As I mentioned before, if time isn't that big a deal, then this workflow is as good as any. However, this is by no means very efficient, and there are alternatives, but unfortunately the old saying "You get what you pay for" is really true. Sonic Foundry is the way to go if you want to cut down on the time and steps. Otherwise, try TMPGEnc again, but try these settings above. You'll have to determine the average bitrate based on how much video you want to fit on each DVD. I wouldn't go much over 2 hours though as the quality will suffer. And, remember that though DVDs say they hold 4.7GB, they really mean 4.7 billion bytes. So, they really only hold about 4.38 true GB. And make sure you leave space for the audio as well.

Define promoting. 
All the best.
