some people anwser that is posible to transcode losslessly from MPC to MP2. If is also possible the inverse situation (losslessly MPC to MP2), the obtained MP2 file can be muxed in an .AVI file (after adding a WAV header) or in a MPEG2 track of a SVCD.
Thus, we can have movies with MPC audio quality!!!
Also we can make a SVCD with only audio tracks; in this way we can listen hours of high quality music in our DVD players.
Somebody could say to me if all this is possible? Or I'm only dreaming?
Full Version: MPC in AVI, SVCD, etc.?
Not much bitrate is spent for the sound part of the movie. And as you know MPC needs a certain bitrate to live up to its great reputation 
I don't know the exact details, but 128 is probably a good guess for the bitrate. I am sure other people will know more about this.

It's true that in AVIs, people tend to use around 120 ish for audio, but in VCDs and SVCDs the bitrates are much higher. For VCDs, the audio must be 224 kbit mp2, and for SVCDs it can be mp2 at any bitrate, but typically is 192 or 224.
So an "mpc mp2" would be ideal for these (especially things like music videos; once you've downloaded the video, just demux the audio and you have yourself a high-quality copy of the song).

You can't use MPC with video.
Not untill there will be a directshow filter.
Forget it, nothing you can do, wait for the filter.

they aren't talking about using mpc with video.. they are talking about encoding an mpc, losslessly transcoding to mp2 and muxing that into a svcd audio track. its possible, if there was a utility to do the transcode, which there isn't right now. but a directshow filter is irrelevant in this case.

Basically, he wants to have movies with MPC quality.. AND he says that it may be possible to make audio only SVCDs. So, no, it's not possible. VCDs, SVCDs use regular MP2. Which needs to be constant bitrate. MPC is VBR and very different.
edit: actually, it may also be allowed that the MP2 is VBR (not sure), but again, MPC is based on MP2, but it's just not regular MP2 (MPEG-1 layer 2).
Don't you think that it would be SO easy to make a winamp plugin for MPC then?
.. just take an MP2 decoder and modify some stuff and in some minutes voila! ..
According to the SVCD standard, VBR MP2 is permitted to use.
Is possible to do this in an inverse way and obtain a MP2 from a MPC?.

Actually, it could be possible to transcode losslessly from MP2 to MPC in theory and get lower bitrates. This assumes that scaling and quantisation of the granule data is done the same way in MP2 and MPC, then you can skip the filterbank process and simply reencode the granule data taking advantage of redundancy coding in MPC to reduce bitrates. At worst, if scaling and quantisation are done different, you will have to requantize the granule data before reencoding.
