Burning with DVDiT PE Question

[jpfrantz]

Yesterday I went to burn a DVD from an MPEG I had captured of Cats&Dogs. I noticed that during the pre-burn phase, DVDiT de-muxed the audio for me. Now, with the original MPEG file being over 4Gb in size, the resulting video+audio files were larger than the 4.7Gb of space on my DVD. Are there any secrets for encoding the audio so the resulting files are small enough to fit on the DVD?
I am using an ATI AIW Radeon 32MB DDR for capture and every MPEG2 capture over about 30mins in length (up to 1 1/2 hours) ends up being 4Gb in size. I assume fixing this would allow me to burn a movie to DVD?
I am also assuming the the DVD has a video and an audio file burned on to it for each movie. Correct? So I need to make sure that my original movie file is below a certain file size for a successful DVD burn?

Thanks,
JP

Generally the DVD it Pe Remux the audio files from your format into PCM 48khz Wav audio file.
Hope that will answer your question

When the proggie demuxed it, it converted the audio from mpg2 to wav, which is bigger. You need to find out ahead of time how big the audio will be, so you encode the video to fit properly. There are several ways to do this, one of them is simply to create a wav file of the movie to check size.

If you have the PE version make sure you have your audio settings set to convert to Dolby Digital (Whatever bit rate you pick is to your own tastes) if it's set to PCM your gonna burn more then a whole gig just in audio. DVDit must demux because it also needs to convert your audio from 44.1 (VCD & others) to 48 (DVD standard)

Since I'm not at my home machine, I don't remember what settings I used to encode the audio so I'll assume it was 44.1 khz. That being the case, will DVDiT PE allow me to give it already demuxed audio and video or must it do that for me? Am I correct in assuming that the audio and video files that reside on the DVD are a result of the demuxing and that the DVD format/players don't allow for one file to contain the audio and video?

If all that is correect, then I must make sure that my captures are small enough to allow for the audio/video to be seperated before the burn. Looks like some trial and error is involved here for each capture....

BTW, how do the movie companies get hours of stuff on a DVD? Are they using dual layer discs? For instance, two epsiodes of Star Trek on one DVD....

thanks,

Well if they use Dual layers then can put 2 hours on 1 DVD with the maximum video bitrate, but most movies under 1:45mins are on 1 single layered DVD. I can put a full movie on a single layer/single sided DVD with great results. Just use Dolby Digital and VBR bitrates. I just put a 1hr 45min movie on DVD with excellent results. I used TMPGEnc and encoded with VBR (Max 9400, adverage 5400, Minimum 0)

Almost no blocky artifacts. As good as any studio production. My original source was a Laserdisc.

Barney,

Cool. I'll give that a try when I get a chance. BTW - What do you use to capture you video? Do you capture to AVI then encode to MPEG? I've had good file size results doing that but it is time consuming (VDub then TMP..),

Thanks again,

JP

If you guys have any good tmpeg templetes for DVDit PE so they are 100% compatible with that program dvd ntsc and PAL plz mail me them on fulmen@clan-c6.com
