Splitting AVI file for burning to DVD

Post by Ken Berry »

I received this as a private email:
Good Morning Ken,

Your name has been given to me by Ulead as someone who may be able to advise me as to how I can split a 7 GB Video AVI file into two parts to enable me to burn onto two DVDs, an edited video, which I have been working on for 2 weeks.

I have tried copying the video twice and deleting the first part on one and the second part on the second copy but when I attempt to burn a DVD from each copy it refers back to the original AVI file of 7GB which is too large for the DVD.

My Pc is using Microsoft XP home edition, I have 1 GB of RAM and 200 GB hard disc. using a 4.2 Intel processor.

Any assistance you may be able to give will be greatly appreciated.

Kind regards,

Leonard Lewin.
I have reminder the poster of Board policy that Moderators and Senior Members/Advisers should not be approached privately but instead post their questions on this Board. This is because other users might have useful suggestions for resolving the problem, and because the response may also other users with similar problems.

That being said, my first question is -- why are you trying to split the file? To an extent, it begs the question of exactly what type of AVI file you are editing. Uncompressed 'raw' .avi is huge -- about 65 GB for one hour of video. DV/AVI, from a mini DV video camera, is compressed but still large -- around 13 GB poer hour. But there are also highly compressed mpeg-4 type formats, such as DivX and XVid, which also use .avi as their distribution format. So we need to know the exact properties of your file. Right click on it within Video Studio and posts ALL its Properties here, please.

However, for present purposes, I am assuming we are talking about DV/AVI. If so, then a 7 GB file would represent only about 35 minutes of video in playing time. Is this so? If in fact it is, then if you are trying to burn video (as opposed to data, archive) DVDs, then even using the very highest quality settings, a project this length will easily fit onto a single layer DVD which can hold up to 4.3 GB of DVD compatible mpeg-2.

And that is the very open 'secret'. You are not actually burning DV/AVI to disc. At some stage, it has to be converted to DVD compatible mpeg-2.

Our recommended procedure would be for you to leave the whole, uncut 7 GB AVI project in the timeline after you have finished editing, then go to Share > Create Video File > DVD, and leave what should be the default settings. This would include a video bitrate of 8000 kbps (the highest quality) and LPCM audio (again the highest quality). After giving your new file a name and pressing OK, it will take some time to render the new mpeg-2. Depending on your computer resources, this will take from about real time (i.e. 35 minutes for a 35 minute project) up to 3 or 4 times that length.

However, at the end you should have a fully DVD compatible mpeg-2 of the whole project, and it will probably only be around 3 GB in size, so should easily fit on a single layer DVD.

When it (the mpeg-2) is produced, you save your project, then open a new one. Don't worry about a name as the objective is only to clear the editing timeline. Then choose Share > Create Disc to open the burning module. Insert your new mpeg-2. Go to the middle of the three icons in the bottom left of the burning screen and make sure the box beside 'do not convert compliant mpeg files' is ticked. Build your menu(s) and burn.
