DVD-Mpg and Mpg2

[edong]

What is the difference? I was thinking I made a mistake of rendering my videos to mpg2 instead of DVD-mpg. The software I used had these options. I have about a hundred of CDs containing mpg2 and now I am about to make DVD-video of them.

mpeg2 can be dvd mpg (=dvd mpeg compliant). it depends on the video properties, www.videohelp.com/dvd#tech .

Thanks, Baldrick

If your authoring software doesnt accept that extension, then demux streams, see: mpeg2 de-muliplexer in tools section, demux elementry streams then author with those.

Just an fyi mpeg 2 can also be svcd not dvd compliant.

SVCD stands for 'Super VideoCD'. A SVCD is very similiar to a VCD, it has the capacity to hold about 35-60 minutes on 74/80 min CDs of very good quality full-motion MPEG-2 video along with up to 2 stereo audio tracks and also 4 selectable subtitles. A SVCD can be played on many standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder / player.

Its generally in the 2000 video bitrate range and has a resoultion of 480x480 which is NOT dvd compliant.

Just a little info. So yes you need to be dvd compliant.

NTSC (NTSC Film)



Video:
Up to 9.8 Mbps* (9800 kbps*) MPEG2 video
Up to 1.856 Mbps (1856 kbps) MPEG1 video
720 x 480 pixels MPEG2 (Called Full-D1)
704 x 480 pixels MPEG2
352 x 480 pixels MPEG2 (Called Half-D1, same as the CVD Standard)
352 x 240 pixels MPEG2
352 x 240 pixels MPEG1 (Same as the VCD Standard)
29,97 fps*
23,976 fps with 3:2 pulldown = 29,97 playback fps (NTSC Film, this is only supported by MPEG2 video)
16:9 Anamorphic (only supported by 720x480)


Audio:
48000 Hz
32 - 1536 kbps
Up to 8 audio tracks containing DD (Dolby Digital/AC3), DTS, PCM(uncompressed audio), MPEG-1 Layer2. One audio track must have DD or PCM Audio.

Just a refresher there Good luck.

Thanks, Yoda. I used Ulead VS6 to transfer VHS home video as AVI then rendered them as Mpeg2, 720x480, 29.97fps (don't know the bitrate). So basically, they are DVD compliant.

I do not understand why the option to render as DVD-Mpg. I am thinking, had I chose this format, there will be no more (or less) transcoding during the DVD authoring process.
