Why does project size double if I touch a mpeg file in DVD builder?

[brianan]

I'm trying to create my first DVD from a home movie. Video capture to mpeg-2 file on hard disk is no problem. However if I touch the file (even to simply trim the beginning and end then the disk project size doubles and the result won't fit on the DVD disk. Is this expected?

 

thanks,

brian

Normal depending on the source file…

 

Guessing you are using something like a DivX file which is highly compressed. Builder or VideoWave will have to uncompress and recompress it if there are any edits to it. When recompressing, it will use a fixed setting.

 

At Best Quality, a 4.7gb DVD will hold about 1 hour of video. Video is measured in time just like an Audio CD so file size is a meaningless measure.

 

There are some 'tricks' to get more than an hour on a DVD which you can browse around here and find. Understand that once you exceed the 1 hour mark, quality degrades.

That 'trick' is to burn the file to an 'image file' (.iso) and use Disk Copier to 'shrink and burn' to a DVD. (And as James said, the quality degrades)
