Making DVD with only audio stream (music DVD) using Adobe Encore

[yup]

Hi folk!
I want make music DVD from my collection MP3 files. I have many album. I want know about possibility making DVD with folowing structure
album as titles, songs in album as chapters.
First off all I merge MP3 file from album and Import asset in project, it is not very good, manualy insert chapters in timeline. May be exist other way. How insert many songs and make that any songs corespond to chapter in title.
with kind regards yup.

Don't try & use MP3 - the quality will stink.
MP3 is not a DVD format, and all MP3 files will have to be re encoded as Dolby Digital files, which means using perceptual encoding on a file that has already had this done to it. Quality will be very bad.
As for manually inserting the chapter points - that is the way it is.
DVD Authoring apps have no way of knowing where to put markers unless you tell them, and DVD-Video is a VIDEO based format - not an audio one.
You could try DVD Architect, as that has "music compilation" mode, but the same problem is going to apply.
MP3 just is not a good format for DVD.

Not necessarily, he could go the PCM route, which would be lossy.

PCM per se is not lossy - it would be decoded from the MP3 file though, and unless you have a way of decoding from an MP3 straight to 48KHz he would also have to upsample.
Still, he'd have to upsample from an MP3 to DD as well.

There really is no good way to do this without taking a quality hit.
Going to PCM WAV would at least not induce any extra compression but he would not get anything like as much content on the disc.

On next night I plane listening test. I have some album with high bitrate (MP3 320CBR, OGG 320CBR, OGG 256VBR).
Decoding to wav use Besweet. Upsampling to 48kHz use ssrc_hp. Encoding to MP2 toolame 0.2i and to DD use Adobe Encore. I am start from 256 for MP2 and 192 for DD. If any advise me I will be glad.
yup.

Oops, forgot about upsampling :o But that aside, MP3->PCM should be lossy should it not? And a DVD-R should still fit 6 regular sized albums (although I concede that with DD that should shoot up to more like 40).

Anyway, you might want to use 224 for DD, from what I've read that would be a bit more appropriate for music content (as opposed to directors commentary, etc).

[neil wilkes]

If using PCM from MP3, it is going to be sort of lossy - the info thrown away when the original MP3 was created cannot of course be recovered as it's gone forever.
The WAV file will still be fullsize though!

Using 224 DD Stereo is un necessary. As long as the encoding is done properly 192 is just fine. Pay attention to the Dialnorm setting primarily.

Going to DD from the MP3-WAV-DD route is utterly pointless, as you will be compressing a reconstituted compressed file. It will sound like Poo.

If you use DD 192 on A DVD-R, you should get up to 50/60 Albums easily. Depends on the length of the album.
