Strange thought: Audio SVCD

[M1ckey M0use]

I was thinking the other night, would it be possible to create a "Audio SVCD"?

My standalone DVD player doesn't support MP3 cd's but it does support the MP2 from SVCD's. So i thought if you create an all black movie on a very low bitrate, it's easy to encode and you have lotsa space for audio left.

That way i still can play a couple of hours(?) from my DVD player. Thats handy when i have a party and don't have time to switch CD's (too buzy drinking beer).

Any thoughts about that?

Mmmh... Sound a good idea ! Except it might be tiring to make black movies which length match each audio track. Unless you make chapters in a big black movie which length matches all the audio tracks which you put together in a big audio file ? Seems possible...

If you make a try, please tell us !

No need to use SVCD to do this (unless you want higher audio bitrates) ... VCD is already enough, plus you will have even higher chances of playback on other DVD players.
In fact, WinonCD has exactly the function you are looking for - the trick is that they don't make a black low-bitrate movie but instead use an mpeg still with audio. The mpeg still displays the title of your song. The feature is called "music album".

It would be very simple to make a movie of exactly the size you want with Avisynth.

just use any source it doesn't matter, but Avisynth needs a sample clip so it knows what parameters to make (framesize,framerate, colorspace,ect)

take a frame

resize it

create blackness from it


Example (X is the number of blank frames you want):

Mpeg2source("Sample.d2v")
Trim(0,1)
temp=BilinearResize(480,480)
temp.Blackness(X)


As for whether or not this MP2 player will work, that really depends on the DVD palyer's CDROM. Some CDROMs will work fine at low spin speeds while others need a minimum speed (like 1X).

Thanks!

I think i'll try the WinonCD option.
And try to find a freeware alternative later..

i'm a liitle confuse, did he meant a cd with mp3 or a audio cd made from mp3?

[wmansir]

The idea is that most DVD players don't support MP3, but they do support MP2 (at least those that do VCD/SVCD). MP2 doesn't compress as well as MP3, but it's much smaller than raw CD audio.

So you make a "Movie" with a very low video birate and high quality MP2 soundtrack. The soundtrack is your CDs ripped and encoded into MP2. You can use chapter points for the tracks.

If the Video had 1Kbs, and your MP2 had 224Kbps, you could get 8 hours onto one 80min CD. Of course the Video probably needs more bits that that, even for a blank screen, and you may want to play around with the MP2 bitrate to see what your player can handle.

I don't know if this works, but that's the idea.

Just make audio only .mpg files, make a black screen still (and any other stills you want e.g. song titles)and put it together with VCDEasy.

No need for WinOnCD or any other commercial software.:)

Mpeg2source("Sample.d2v")
Trim(0,1)
temp=BilinearResize(480,480)
temp.Blackness(X)

No need for this. Just type:

BlankClip(length=whatever,width=480,height=480,fps=24,color=$000000)
