hello everybody,
i captured from my dv camera movies to the computer and then i realized that they take a lot of memory something like 4 giga for 15 min
and when i edited the movies to one and wanted to burn them with this program i saw that 19 min took only 800 mb of my dvd disc although i chose the best quality(100) in dvd-pal format.
and i wonder if this is normal beacuse till now i thought a moview of 20 min would take at least a whole dvd disk.
thanks for the helpers.

Saving to the pc from your camcorder should always be done in dv-avi file format, which is a direct copy of the tape. This gives you best quality and ease of editing. Drawback is as you have found 1hr = 13gb. But hard drives are cheap, so it's best to have a large dedicated hdd added to use.
When you make a dvd for watching on a dvd player you need to convert it to mpeg2 format, in the guise of vob files, so that the dvd payer will recognise and play it. The mpeg2 file is compressed down, and depending on the settings used, top quality mpeg2 files are generally around 4gb per hour.
If you saved the dv-avi file to the dvd as a data disc, then yes, you'd only get 15-20 mins on it.

so what format is better?
dvd pal or mpeg 2?
and if i burn it as a data disc could i see the dv movie in a dvd player?
thanks a lot anyway for the previous answer.

I'll see if I can help you a little more on the second questions. DVD, PAL or NTSC, are the same as MPEG2. No, you can not save the AVI file on a disc and have a Stand alone DVD player recognize it.

As youre first responder indicated, the AVI format is what is used when capturing and editing vdeo. It is as close to raw footage as you want, raw AVI would be closer to 65Gb per hour, so there is some compression on what you are working with, about 5:1. AVI seems to give the least amount of problems for editing you video, many people have had problems when re-editing MPEG2 files. Searching through the VideoStudio forum will show you some of these problems.

Personally, I capture in AVI, trim to the clip I want (cleaning up the begining and ends of the clips), then convert it to MPEG2. Then I string the clips together with transitions and create my DVD. Since I do not re-edit my clips, other than maybe shortening them further, I feel safe with saving the files as MPEG2.

Hope that clears up some of your questions. Check out the VideoStudio forum for some very good information, and the sticky note on top gives you good information on proven ways to create good DVDs.

ok but i'm a little confused.
if i understood you correctly there are two parts for editing and capturing a movie-the format which we capture and the format whuch we burn?
because for instance i captured in a avi format (while my project settings were on mpeg ) and i burned using the dvd pal format.

There are two formats that the video gets written in. You capture it in AVI. You edit the project using the AVI files. When it is processed for a DVD it changes the video into MPEG2. You will notice the size of the AVI files would preclude them from being burned to a DVD. 1 hour of AVI capture is ~13Gb, so you know there is some compression going on, that is the AVI to MPEG2 processing. The reason that I do the conversion first is that it shortens the time it takes to create the DVD.

Hope that helps clear things up a little.
