Estimating size of DVD needed

[Hawk10Vid]

I have prepared a number of videos (specifically some recordings of education classes of 30 minutes to 2 hours)) and want to put them onto an autoplay DVD. Is there some way in PE9 to pre-determine what capacity DVD will be needed to hold a video? I would like to burn the videos onto some of the mini-DVD's which hold about 1.4 GB. But, after I burn a regular size DVD, it shows that all the DVD capacity was used. I'd rather not have to go to the higher capacity DVD's if it isn't necessary. Any direction would be appreciated.

Hi Hawk,
You can fit one hour of video on a standard DVD without any problems. Some people will even put 1.5 - 2 hours on a standard DVD and say there is no quality loss. A Standard DVD will hold about 4 GB of video, so you might be able to get 30 minutes on one of the mini-DVDs with a little quality loss, there is no way you can get 1 - 2 hours worth on there without quality loss. I don't even know if Premiere Elements will let you burn to the Mini-DVDs anyway, has anyone tried?

...I don't even know if Premiere Elements will let you burn to the Mini-DVDs anyway...

Since most of us don't burn directly to DVD anyhow, using any of the popular DVD writing programs should detect and handle the miniDVD I would think. I haven't used a miniDVD in a long time myself.

Of course, it has to fit. Wikipedia indicates the size of a miniDVD is 1.4GB.
