Dolby Digital


uva25

Question

I created a DVD music disc and noted that all the music was now played in Dolby Digital on my receiver. I had ripped all the mp3's a few years ago(using Windows Media Player or Real Player) and I didn't realize they were all in Dolby Digital. Did it "upconvert" them or was the Dolby Digital always in the mp3 but my prior software didn't allow it to be played.

I'm not sure as my receiver definitely showed "Dolby Digital" when the dvd was played.

 

AC3 is licenced Dolby Digital. Does not mean that it is 5.1 surround sound. EMC8 does not support surround sound using any audio format. In fact if you have an MPEG video with 5.1 audio and MyDVD has to re-encode it, the 5.1 will be lost.

I prefer eating a Whopper while flipping through XM stations.

I'm not sure as my receiver definitely showed "Dolby Digital" when the dvd was played. In the past it would not light up. I was confused myself though.

I just turn the tv off or turn it to a different tuner and show a ball game or something with the music playing. As for surround sound, most cds are not recorded in surround sound so how would this work. Unless of course you are taling about SACD or something like that. Is it able to do a simulated surround sound if the original MP3 did not contain surround sound?

 

ggrussell, why would anybody encode in AC3 if not for 5.1 playback? I thought I could rip the music part of a concert DVD with full 5.1 surround and burn it into a Music DVD for full 5.1 surround sound without any video (aside from the menus). It seems I was wrong, right? :)

ggrussell, I am new to all of this so bear with me.

Are you saying that EMC8 will make DVD videos in 5.1 if the mpeg was originally recorded in 5.1?

I have a new HDD camcorder which records video in mpeg and 5.1 and purchased EMC8 because the sales rep said it would but I am having difficulties.

Not only does the program crash, ERROR 84???, when I try to add tranistions but when I do make a DVD (w/o transitions) I can't for the life of me get it to make a DVD in 5.1.

Can you assist me?

 

 

 

Simple, my camcorder doesn't support surround sound and AC3 2 channel audio is compressed more than PCM or MPEG audio. That gives more space for video.

 

Granted you are talking about music, but this was a new feature just added in this version. Very few under $99 programs support true Dolby 5.1.

Interesting. Thanks for the orientation.

When you make a DVD Music Disc you get three choices as to sound.You can get AC-3,PCM or MPEG.Each uses a different amount of compression and has different characteristics.To get the best sound use PCM.It is not compressed,has good surround sound but uses the most space on a disc.Depending on which format you use depends on the compression and the amount of tracks you'll get on the disc.If you use AC-3 you may get upwards of 400.If you use PCM you may not even fill 1 track list(98 tracks max.).These formats are all encoded when you make the disc.That's part of what takes so long to make the disc.

Where do I see the choice between AC-3, PCM and MPEG? Thanks.

Unfortuanately, most sales rep aren't as knowledgeable as one would hope. EMC8 does NOT support Dolby 5.1. However with my own personal experience if I do not make ANY EDITS, MyDVD would use smart-render to create a DVD. Once you make a cut or add a transition, that forces the program to re-render. Videowave and MyDVD render in 2 channel only. Since you have a Hidef camcorder with Dolby 5.1 sound and if you want to keep 5.1, you need to purchase another program.

Thanks guys!! What applications do you generally use these DVD music discs? I'm thinking great for parties, Create a DVD for each genre.

I haven't made too many other than playing around. I also figured it's another way to archive my music. When I grow up, I'll get a dvd audio player for my car to enjoy hours of music whilst waiting in traffic.

Good idea. 10-20 DVD should cover my collection. Are dvd audio car players mainstream? The only problem I see in a car is navigating through the countless hours of music.

The part I like about them is using PCM encoding and getting surround sound instead of just simple stereo.The party idea is a good one if you play it in your DVD palyer thru your home system.There's not much to see video wise except for the menu navigation.Depending on what menu combinations you use you can sort by title,artist,album whatever info you choose when you build them.

Ahh, you can select a different image for each piece of music - that's a bit more interesting. :)

I don't think any part of EMC8 supports surround sound. Only two channel stereo. Even the AC3 is two channel stereo.
