SolveigMM MPEG2 Requantizer Component is an engine designed for a fast and quality recompression of MPEG-2 high bitrates video.
The component was implemented as DirectShow filter.One of its main purposes is a fast DVD back up.
The demo application inputs are MPEG-2 Video Elementary Stream, MPEG-2 Program Stream, DVD VOB files.
It splits video/audio streams, recompresses MPEG-2 VES in concordance with set compression ratio (picture 1) and writes audio/video streams to respective files.
Audio streams are dumped as is, without recompression.
Total audio/video files size is approximate size MPEG-2 or VOB of file containing these streams after multiplexing.
Such one can estimate potential VOB size decrease.

Thanks for the information. By your registration email address, i see you are affiliated with SolveigMM. You also posted a similar thread here.
Are you calling for people who want to participate in a betatest? It's not really obvious from your posts. I ask because registering an account only to advertize a product is not a favorite here.

Hello darkman,
What difference with CCE 2.67 (report quality speed)?
Can it work in HD?
Bye.

Hello CiTay,
Actually the aim of my posts (this and about the trimmer) is to discuss the soft with both users and developers and shure beta testing is welcome.

Hello guada,
We have not compared the MPEG-2 Requantizer with the Cinema Craft Encoder. Is CCE able to requantize existing MPEG-2 files? We tested it with Moonlight MPEG2 Encoder.
The result as follows:
on PC - AMD Athlon XP 2200+, 256 MB of RAM 10 to 5 Mbit MPEG-2 video recompression faster than real-time playing in 8 times .
It is faster of Moonlight Encoder in 6-7 times.
As for the quality, recompressing of DVD video from 10 Mbit to 4,5 Mbit is
without visual quality degradation. PSNR is 39-40 dB.
And shure, it works with HD MPEG2 properly.
Regards,
Dmitry
how does this compare the hank315's HC Encoder?
SolveigMM MPEG-2 Requantizer is not full MPEG-2 Encoder as HC-MPEG2 encoder or CCE. Generall encoder input is raw video data (YUV or RGB) and the requantizer input is MPEG-2 Video Elementary Stream.
Therefore a comparison of the requantizer with any other encoder is not correctly, since it operates much faster in nature.

Are you telling us that there is 5,5 Mbps of padding in such a DVD video source ?
(btw 10 Mbps is peak value for a DVD video, while 4,5 Mbps is probably an overall value)
Hello Gabriel,
That's right, I've said this just so
But there is not padding. There are almost all 64 non zero DCT coefficients.
Thanks for the explanation
But the movie with mentioned 10Mbit bitrate had average bitrate 8,8 Mbit.
Actually such high-bitrates movies are contained on two-layers discs (DVD9) with capacity of 8,5 GB.
Being foreseen your next remark I notice that I mean only video bitrate
It would be great if you tested it by yourself and informed the results here.
We will discuss it with pleasure!
Regards,
Dmitry

The new version of SolveigMM MPEG2 Requantizer DirectShow Filter (v.1.01) has been uploaded.
http://www.solveigmm.com/files/SMM_MP2Req_2005_04.06.zip
The version has been impoved in terms of stability to MPEG2 VES bitstream errors.

The version has been impoved in terms of stability to MPEG2 VES bitstream errors.
New version 1.1 is available
It accepts advanced parameters:
- a unique compression rate for each picture type I,P,B
- amount of macroblock DCT coefficients to be discarded

Does it work with MPEG1?
EDIT: Ok I found out it doesn't.

I played a bit with this tool and I must admit that speed, quality, and compression combo seems to be really very impressive. But I'm having problems using it in practice - I have a LP DVD (low resolution & video bitrate) consisting of 8 VOB files (and 2 IFO & BUP files), after requantization I get 2 streams (x8 of course) - MPEG2 video & LPCM audio. Now, how can I multiplex them back to 8 VOBs? And can I use original IFO & BUP files with these VOBs?

Hello rutra80,
First of all thank you for the interest to our products!
Sure you can multiplex your video/audio streams after requantizing.
There are many programs for this purposes.
Take a look at Elecard's XMuxer for example.
http://elecard.com/products/xmux_pro.shtml
As for IFO files I'm afraid the original ones will be failed after you multimplex requantized VOB files since they contain certain byte offsets and they will be affected.
