Question about burning file size

[magikero01]

Sirs, i have a question

Whenever I burn a MP4 movie about 400 MB, it automatically fills the 4.5 GB space in the DVD, how come it's doing that? When it just suppose to fil in 400+ space. Hmmmmm.. I use Nero 7 and I only have a generic burner. Halp!

Probably because Nero is re-encoding it to MPEG-2 format to be able to make a DVD from the file.

If you want to keep it in MPEG-4 format, burn it as a data file instead.

And welcome to our forums.

You are telling Nero to convert the file into a DVD Video format. Mpeg-2 compresses a lot less than Mpeg-4, so the file sizes grow. By default, Nero (and most conversion tools) will try to use the highest possible bitrate to minimise quality loss during conversion. My bet is that the running time of the video is round 90 minutes, which fills a DVD.

If you just want to burn the file to a DVD as data, use the Burning ROM part of Nero, Not Nerovision / Express.

Or start using Imgburn, as it doesn't do any conversion at all.

Some more questions..

- Please recommend a good freeware for playing DVD movies. My powerDVD trial will expire within this month.

- How would you know if a DVD is re writable? Example: I burned a movie and it failed, can I use the failed dvd again?

Media Player Classic or VLC or KMPlayer.

You can use DVDIdentifier to check if you have a RW media....if it doesn't say RW on the dvd media.

If you have Nero, CD-DVD Speed in "Tools==>Disc Info" will give you details about your media (DVD-R/RW, blank/finalized, manufacturer, etc.).
