Using DVD2SVCD to rip DVD9 to DVD5

[cracken]

Hello, I don't like using utils like DVDShrink, CloneDVD, DVD2ONE... So I want to use DVD2SVCD to get a mpeg video compatible with DVD standards.

For audio, I use "Do not Convert...", and frameserver with DVD or CVD with Bilinear Resize. I´m using CVD when I want to burn 2 or 3 films per DVD-R (If someone could tell me an average bitrate limit to use DVD resolution... For Example: Avg. Bit. > 2500 => DVD resolution; I would be very thank).

I´m using min bitrate=500 and max=8500, but if someone could tell me the exact DVD standard bitrates... thanks again.. ;-)

But my biggest problem is to choose an aspect ratio, I want to get a video with the same aspect ratio than the original, so 16:9 (borders added, encoded as 4:3) is refused, but I don't know which to use... 4:3 or anamorphic?

When I will get the mpeg video from dvd2svcd, I´m going to demultiplex it and author with IFOEdit, whit 2 audios and *.sup subtitles (ripped by SubRip).

If someone want to send me an *.ini file for dvd2svcd to ask all my questions, I would thank him a lot... (I´m using DVD2SVCD 1.0.9b3 and my e-mail is jmegolla@hotmail.com).

If someone thinks that this way is not a good idea and knows other way to rip DVD9 using CCE and is easy to use... (note that I want to use DVD2SVCD because once I have the proper settings... I only have to click GO!), please, tell me it.

THANKS so much, Regards CRACKEN

PD: Excuse my english.. I´m spanish.. so it isn´t very good... I hope you can understand what I want to say ;-)

Hi, cracken, welcome back to the forum.

You may want to try DVD2SVCD 1.2.1b3, the last version. It supports DVD2DVD directly, and will set up all the parameters for you.

Well, there is no final answer to that question, since it varies from movie to movie. A better indicator suggester for which frame size to use it quantization. You may find this guide (http://forum.doom9.org/showthread.php?s=&threadid=62858) useful for that.

That's an easy one: use the aspect ratio from the original :)

If doing a dvd to dvd you must choose anamorphic. Anamorphic in this case = no borders added. (per dvd2svcd when I asked him)

If the source is not anamorphic and you resize it anamorphically, wouldn't you get a 544x480 frame size (assuming NTSC), where you'll lose valuable sharpness from the original?

Thank you very much for the answers!!! :)

The guide is very good!! :)

But... about aspect ratio, DVD2SVCD is made for 4:3 TV... I mean, if you have a 4:3 TV you should choose the aspect ratio from the original, so if the original DVD is 16:9, it will play vertically expanded on a 4:3 TV, so DVD2SVCD adds the needed borders. But if yout TV is 16:9, and the original film is 16:9 too, you shouldn't choose 16:9, or you will get thicker borders and your backup will play vertically stretched :angry: . Then, I have to choose an aspect ratio with no borders, but I don´t know which of both (4:3 or anamorphic).

If in anamorphic mode I loose sharpness... should I use 4:3?

Thanks again, CRACKEN. :devil:

I don't know if I understand your question. If Anamorphic is chosen, there is no resizing assuming you are using dvd2dvd and are making a standard DVD. The aspect ratio doesn't really matter. The script would be something like this for a NTSC DVD to DVD conversion. You could just as well remark out the sizing line as it is smart enough to do nothing. There would be no speed change using it, or remarking it out.

mpeg2source("D:\dvdtest\DVD2AV~1.D2V")
lanczosresize(720,480,0.0,0.6)

You are right, but there is no resizing either if you select 4:3. The generated script is the same.

So the correct answer would be "Use anyone, it makes no difference".
The aspect ratio doesn't really matter.
But there's a catch. It doesn't if you don't want to crop/resize.

I prefered to give craken a more general answer, since he is willing to use CVD as output, cropping with a good resizer tool will be needed to keep the AR.

If you use FitCD, for example, you will have the result I mentioned for DVD and 272x480 with CVD (both assuming the ITU standard correction factor) and no overscan.

Using FitCD (or FACAR) will also result in him optimizing the encoding time by skipping the source black bars and the overscan overhead.

I think that when using a resizer tool, maintaining the source aspect will keep more sharpness and correctness.

lanczosresize(720,480,0.0,0.6)

@craken: DDogg surely meant Bicubic above. (Don't be frightened to use Lanczos as a good alternative when DVD range bitrates are at hand.)

D9: Since "help me with this" in nature, moved to basic forum.

Yes, there is no resizing, but I believe there is a difference to be taken into account. MPEG stream headers will be marked with a different DAR (16:9 in anamorphic and 4:3 when select 4:3, no borders...)
I don't know what happens in authoring with Scenarist, but if you use this files as input to IfoEdit, the IFOs will be written according to this MPEG headers, so the final DAR of the DVD will be different. This will be decoded by the settop and, during playback, a resizing should be applied if needed, to keep the final DAR as the original one.

So, you have to use the correct DAR. (16:9=anamorphic is the most usual, but there are some 4:3 DVDs)

Anyway, we have DVDpatcher tool which save us of a new encoding in the case of error.
