Re: DVD Authoring......PCM or AC3 audio?

I dont know what part of 'AC3 is LOSSY' you peeps arent getting...but if thats what you really want, find a site that doesnt care about quality and mp3's are considered a great thing

Re: DVD Authoring......PCM or AC3 audio?

If you have Pink Floyd's The Wall on DVD, I'm sure most people have that one, it's essential in life. Compare the PCM to the Dolby or DTS on that DVD. The PCM just blows the others away, completely! Using a good system always helps. I can't stand it when music DVD's (commerical..especially) don't have PCM, it's so much better.

That aside, most available AC3 encoders suck badly which gives AC3 a worse reputation than it deserves, though the format itself isn't that bad (potentially even on par with DTS, seems nobody ever bothered do a proper formal test of this though). It certainly helps to use a good encoder and a sufficiently high bitrate.

On a related note, the same also helps when it comes to the video. (because, you know, mpeg2 video is lossy too, ohoho </Sherlock>) I'm very much not impressed with the performance of commonly used mpeg2 encoders. More often than not, throwing more bitrate at these doesn't help either - it's not all that uncommon that you could get away with significantly lower video bitrates and still end up with better quality by using a good encoder.


...my point? Err, I dunno... something like "I wish more people would actually know what they're doing or talking about when making codec and bitrate choices or recommendations," I guess.

Re: DVD Authoring......PCM or AC3 audio?

absolutely correct ssamadhi, but for the purposes of 99% of the stuff that goes thru this site, i'd still have to say PCM over AC3...

Re: DVD Authoring......PCM or AC3 audio?

pcm is best hands down ac3's only benefit is 5.1 and a smaller file size for the audio files...but also "compressed"...while pcm is pure "un compressed goodness" nice job guys ...keep up the good discusions. PCM is KEY 2 Sucess as far as i see it.....multitrackz brauh

Re: DVD Authoring......PCM or AC3 audio?

Let's just AC3 blows and LPCM rules.

Don't get me started on the compression issues of AC3.

If it was up to me we would all be watching uncompressed avi files with LPCM audio!
