Better Quality with TMPGEnc

[davidb0000]

I have downloaded a few Divx videos from the internet that are ~700MB and are perfect quality(when I say perfect quality, I mean exactly this). I tried to do the same with my own DVDs. Here is what I did so far:

I ripped the DVD to get a large VOB file on my HD. Then I used DVD2AVI to get the D2V and WAV files. This all works well.

Then I used TMPGEnc to combine them to create a MPG file. Here lies my problem, one of the follow always happens.

* There is a black bar on any of the four sides of the video(be it one pixel or 50, it is still obviously unacceptable).
* Some of the video it clipped on the edges(be it one pixel or 50, it is still obviously unacceptable).
* The quality is pixelated at full screen. It is somewhat like expanding a 320x200 BMP to fill your 800x600 screen.

I never see any of these problems when I run the files I get off the Internet. Granted, they are Divx, but that is the step after TMPGEnc, which I will do if the MPG process works.

I am desiring a 720 x 368 video with perfect quality(this does not mean REAL WORLD quality, but quality which will allow the human eye to ignore while perceiving "motion". All Internet Divx files ~700MB are of this quality. That should be enough to describe to you what I am looking for.

Are there certain settings I should be using in TMPGEnc? Am I using the wrong utility?

why go through TMPGEnc ??? the movie is already in MPEG2 format....just convert that to Divx.

Yeah, when you're in dvd2avi instead of picking the save project option, frameserving and then converting to divx. Just hit the Save AVI (remember the program is called dvd2avi ) The standard AVI codec window will pop up, select the divx codec of your choice, adjust the compression as you see fit, and you will have an avi. As I remember, been a while since I encoded to divx, you will not have sound in the AVI, but dvd2avi will process the sound into an uncompressed WAV. Then fire up Virtuadub, use a direct stream copy for your video, under audio select WAV file, put the proper delay which Smartripper puts in the audio title, save that avi and you should be good to go.

As Bartman said, converting the dvd twice (once in TMPG and then in Virtuadub (or whatever program you use to encode your AVI's) will cause a loss in quality. Even though this is still two steps, the video only gets converted once so you should have much better results.

Dont listen to these guys.


What you wanna do is use DVD2AVI and make a project file then frameserve that using VFAPI or AVISYNTH your call.
Then you wanna encode using either Nandub or DivX5.02 Pro.
You should use AC3dec to make a wave from the vobs then encode that wave using Lame and make a VBR MP3, then mux the DivX you made with the VBR MP3 using Nandub.
And you will have a great quality DivX.


This from Doom9's

DivX Encoding

There's three kinds of DivX codec now and an alternative one: DivX3.x which is the more well known and has been around for a while. It's also known as DivX and is basically a hacked version of Microsoft's MPEG-4 v3 codec. The 2nd DivX codec is DivX4, by DivXnetworks, a completely new codec written from scratch but which is not much used anymore since the same company has released DivX5, which offers more features and better quality than DivX4. XviD is a pretty new codec as well, still in alpha state but it already gives very impressive results and it's open source

Whichever codec you chose is really up to you. If simplicitiy is your goal Gordian Knot offers easy DivX3 and DivX5 encoding whereas the XviD setup is still a bit more complicated. And in terms of quality you best read up on your own.

And Sept 19th Microsoft will release WMP9 and the WMV9 codec aka Corona. I look forward to this

Hope this helps.

Bel had the only acceptable answer.

Step 1) Use DVD2AVI
Step 2) Use VirtualDub

Seems simple enough, and the quality is perfect.

EOT.
