High Quality divx\xvid to DVD convert. How to do it?

[fgtan]

Hi guys.

I have some high qualitydivx\xvid files and I want to convert them and burn to DVDHigh Quality.

I made some trials using tmpenc and never had the same quality, sharpness and definition on the images as in my divx\xvid files.

Does anyone knows a good guide and the right software to do it?

Thanxs

Not certain on what you mean by DVD "High Quality"... Usually when you you redo the project from DVD to Divx you lose a little bit of the quality, even though you may not notice it visually..Remember when you are converting it from a 4.7 GB file down to a 700MB file, you're losing data...So when you try to redo it back to a DVD, your working with a 700 MB file... Ain't no way that I know of that'll restore it to it's perfect DVD quality when you remake it back into a DVD...Just my 2 cents...

Thanks for the info...

Just to be more specific....I am not getting at least the same quality of my divx files...I mean...I´m losing more quality when I convert the file to a mpeg2...

What art the dimensions of your Divx/Xvid files? What frame rates? How much (running time) are you trying to put on a movie DVD? Are you making PAL or NTSC DVDs?

They are mainly rock concerts, they take from 30 to 120 minutes and most of them are 25 fps and I am trying to make ntsc dvds.

If they are 25fps I would just make PAL discs. Most likely, your player will play them fine.

What are the durations, file sizes and dimensions (e.g. 640x480) of your files? That will help us.

I'm currently trying out and using cucusoft video converter pro, which handles divx, xvid, wmv, mpg, rm, avi etc, etc ...

Its slow, an overnight job if you have a lot or a big file, but does a pretty good job, has batch support and so far seems to be able to keep the audio in synch after conversion

Plus you decide on the fional filesize. The bigger the filesize the better the chance to keep the quality as high as possible

You can resize to DVD standards or whatever size you like, it can also save as VCD, SVCD, DVD or MPEG1 and MPEG2 as a custom size


Problem is, it outputs the converted video as only MPG, but they also offer a free utility on their website that will convert an MPG into DVD comptable files. EG VOB's, ready to burn onto DVD

Sorry, by "dimensions" I meant the frame size. How many pixles tall and wide. With the 120 minute files, do have to have the whole concert on one DVD?

Post a small <2MB clip of the divx material up here.

The reason for all the questions is because your optimum strategy will depend on the details.

If you want an easy, quick, dirty strategy that will probably work for all your AVI files use something like the following settings:





The results will be a little jerky (because of the crude frame rate conversion) but otherwise the picture quality should be about as good as the sources (unless your sources are high def). And you will only get 1 hour on a DVD -- a tremendous waste if your sources are 320x240 or something like that.

TMPGEnc uses a crude bilinear resizing algorithm. To get better resizing you can use AVISynth and its LanczosResize filter.

If you want non-jerky results you'll need to use a better frame rate conversion method. There are about a million threads here that deal with that.
