Hello,
After doing some dubbing in VD, what is the best compression engine so i save the avi with almost the same original DVD quality?
Thank you.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Lossless codecs like HuffYUV, Lagarith, UT Video Codec give the best quality (ie, no loss of quality at all). But they don't compress much. You'll probably want to use x264vfw for good quality and good compression. Unless you have some other hardware requirement. Like the need to play your files on a Divx/DVD player.

x264vfw gives around 2gb for good dvd quality on a 2 hour movie,HuffYUV, Lagarith, UT Video Codec will give around 30-60 gb depending on settings.
I think,therefore i am a hamster. -

Only ripping (backing-up) DVD to your HDD will give you 100% quality same as your source. All other members already suggested you best compressors. Try different compressors. You are the only best judge coz only you know how your source looks like. Rest members (including me) are sharing the exeperience.
In general, any video editor has nothing to do with quality, it just facilitate the encoder in a particular fashion.Last edited by enim; 28th Jul 2013 at 00:37.

It depends if you need to hit a specific file size or not. I guess it was more of an issue 5 years ago
when people were obsessed with fitting a particular video on a CD.
Try the default settings, single pass CRF and quality between approx. 18 - 23 (lower number = higher quality).
Final file size is unpredictable, but you get the quality you ask for.Last edited by davexnet; 28th Jul 2013 at 08:05. Reason: typo

Thank you davexnet for your reply,
I don't care much about the output size cause i will re-encode it anyway into DVD again but i care about the quality, i want to get similar quality to the original file before dubbing with a reasonable size not like 20 or 30 giga byte.
So what do you suggest to get a good quality? -

If you're comfortable with Virtualdub, perhaps quit using XVID and use the x264vfw mentioned earlier.
Do some test encodes and see what you think. -

Don't shoot me but can you teach me how? it's ok not to if you don't have time.

Now we know you're starting with a DVD and want to end with a DVD. (As Hech rightly points out, you should have said so at the beginning.) What are you doing in between that requires anything more than simply copying?
-
Sorry but i don't want to go into DVD authoring issue itself as i have no problem with that but my problem lies in the video quality.
DVD > Dubbing > DVD
The problem is with the second step, i'm losing quality because of XVID or because i don' know how to use it properly, that's it.
frameserve to your MPEG 2 encoder (for DVD).
or
export with an MPEG 2 codec (old version of ffdshow) with DVD compatible settings. -
Frameserve from virtualdub to TMPGEnc for example:
https://www.videohelp.com/oldguides/virtualdubframeserve
Not all encoders support frameserving. -
Forget about Xvid or Divx or even h264 for that matter.
DVD is MPEG2 - MPEG2 is DVD. Going to anything else in-between besides a huge, lossless video codec WILL result in quality loss.
Frameserving from VDub is pretty easy but the encoder I frameserve to is not free so maybe someone else will come alone with a free encoder that accepts frameserving.
No doubt someone will come along and mention scripting or "avisynth".
You don't wanna go that route. -
Exactly. Unless you are doing something to that video in between. You don't need the middle step.
DVD>copy to hard drive>Burn to new DVD
What I suspect you want to do is DVD>Copy to hard drive>Extract clips>Rearrange Clips>Burn to new DVD. (Though you have not said so.) You still do not need to reencode anything. -

Install ffdshow version 3631 (the last one with the MPEG 2 encoder). In VirtualDub select ffdshow as the encoder. Select the MPEG 2 encoder, set up all the options. Save as AVI. That will create an AVI file with MPEG 2 video inside. Demux the MPEG 2 video and use it to make a DVD in your DVD authoring software.
-
Yes, but you have to pay for TMPGEnc.
VirtualDub also has the ability to use external encoders:

You might try that with HcEnc (a free, open source MPEG 2 encoder). -
Try Matrox VFW codec:
The Matrox Video for Windows (VFW) software codecs let you render and play back Matrox .avi files in your VFW programs without having Matrox video hardware installed. This version provides codecs that were previously available only on systems that have particular Matrox video hardware, such as Matrox Axio. This includes the Matrox DVCPRO HD codec, and "+ Alpha" versions of the Matrox uncompressed and MPEG-2 I-frame codecs. As well, the Matrox VFW MPEG-2 I-frame HD codec now lets you render and play back Matrox MPEG-2 I-frame .avi files in all HD formats (720p, 1440x1080i/p, and full-size 1080i/p).
The following VFW software codecs are provided for use on 32-bit and 64-bit Windows operating systems:
- Matrox DV/DVCAM
- Matrox DVCPRO
- Matrox DVCPRO50
- Matrox DVCPRO HD
- Matrox MPEG-2 I-frame in SD and HD resolutions, with or without alpha
- Matrox Uncompressed in SD and HD resolutions, with or without alpha
- Matrox Offline HD
- Matrox M-JPEG and HDV (playback only)
