DvD-r supposed top be 120 minutes?

[meanrat]

Hello!

Can somebody please explain the following?
If I have 2 videofiles from let's say, 44 minutes long. It is AVI. I encode these to MPG when I want to copy them to the DvD. Then with TMPGENC DvD I copy them to DvD. But then it says it is too much for 1 DvD!

How come I can backup my DvD's which are 2 hours playtime, and can not even put 2 mpg-files of 44 minutes long on 1 DvD? It's only 88 minutes.

Is it possible to put these on 1 DvD?

Please help!
Thank you very much.

The DVD capacity is dependent on the filesize rather than the length of the video. the filesize itself depends on the duration of the source file(s) and the bitrate at which you encode to mpg.

I am guessing that you have encoded your source avi files to mpg at too high a bitrate, or pehaps with uncompressed pcm audio. I would recommend that you use one of the bitrate calculators in the "Tools" section, and use the specified bitrates for video and audio when you encode the avi files (select single DVD-R as your destination format).

It sounds like a high video bitrate and PCM audio together...

FYI, Using VCD mpegs you can get almost 7 hours on a DVD. It's all in the encoding method.

It's worth noting (so the two hours part is answered) - those figures come from the constant bitrate settings on standalone video recorders.
