Hello Forum
Recently I made a DVD using some authoring program. I have 13 mp4 clips, alltogether 611 MB, 1:50 hrs, with some simple menus added, I ended with a dvd folder size 4.25 GB. How 611 MB "swell" into 4.24 GB ?
The dvd plays well, I am just interested what made the material become so large ?
Explanations will be appreciated
Thanks

It depends how you specified the burn process for the DVD. The options are usually to either leave it unclosed so that you could add more files later as if it were a data disk or to finalize the disk to make it act like a DVD. It appears your authoring program chose the latter and so the disk has been set up as a DVD and in this case you can't add additional files and the disk is made to appear full.
Authoring a DVD requires that the video streams be compliant with tight specifications.
MP4 clips are not DVD-video compliant, so your authoring program re-encodes them into MPEG-2 compliant VOB files.
Depending on the quality, bit rate, and size parameters that its encoder is set to use, the final file size may shrink, grow, or stay the same,.
NavyLCDR, thanks for +1'g the correct answer for mike s. I deleted my earlier post 'cause I thought the authoring program was in this case simply being used to make a normal DVD :)
Hello philc43
Thanks for the answer \ explanation. I just wanted to know how many clips can I add to make a dvd not to eceeding 4.7 gb disk,

As stated above, it depends on the settings used and the authoring program settings. Most will tell you if the setting exceed the limits.
