mac and video editing

[mgfredy]

Hi everyone

Have purchased a macbook great little machine i brought it so as it handles hd editing very well. But now confused - i have a sony hd recorder with 40gb memory have down loaded it on to mac and have burnt some video to dvd but only managed to up load about 10 mins before dvd full its a single layer disc. Is this right if so why can i only record such a small amount video on to disc

Very new to all this any help would be much appreciated

cheers

Yep and they are great programs but when i have come to burn my stuff on to DVD be it a single layer disc it was full after 12mins this isnt right - any ideas what i may be doing wrong?

cheers for your help

How much you can fit on a DVD is determined by file size, not by duration. A single layer DVD holds roughly 4.7GB of data. This means that - whatever the length of your video - you need to compress it to fit the medium of a 4.7GB DVD - that is, the file size of your finished movie needs to be less than 4.7GB. Thus, the longer your video, the lower the bitrate you need to use when compressing it to fit on DVD.

iDVD will execute the appropriate bitrate and compression for you. Just drag your full-resolution .mov file into the iDVD theme you've chosen, or use File => OneStep DVD from Movie if you want to make a DVD that plays automatically, without a menu.

Thanks for that but i am real novice when in Imovies i simply use the share bottom to go into IDVD and press burn no options i can see about the bit rate etc. Also if compress the file do i loss the HD quality if so any point of buying a hd video camera.

Sorry for being a complete idiot

Desperate need of help

cheers
