Why Does One 15Min Movie Take Up 1Gb Of Space?



I've recorded seventeen 15 minute programs from sky on to one DVD. Importing each video, creating either 15 x 250mb mpg files or 15 x 150mb mp4 files.


When using MyDVD to create a new DVD, adding just 1 mpg movie uses up 1gb of space !!!! That means I can get just 4x15 minute clips on one disc?


What am I doing wrong?

You're doing nothing wrong. A standard DVD uses MPEG-2 encoding, which is not as compressed as your .MP4 files, so when you run your files through MyDVD, it re-encodes them to MPEG-2, which takes up more space. For a standard DVD, playable on a set top DVD player, you should figure about 1 hour of video on a single layer DVD at best quality. So yes, 4 - 15 minute clips. You could try a higher compression rate, but in MPEG-2, you'll probably start to notice a reduction in quality very quickly.


You're seeing that video encoding technology has advanced since the DVD standard was produced.
