Program changing disc space size usage

[NOKNOT]

I have been making several home movies using MovieStudio 11.5. All of them have been the same length, about 1hr and 30min. Up until the other day they have been about 4.5 or 4.6gb before rendering. The other day I had a home movie the same time length, 1hr and 30min, and the program said it it would take 6.75gb space.This could not be right. I put the same files into another program and it said about 4.6gb. I uninstalled VideoStudio, then reinstalled it, loaded the files back and it said 6.75 gb space needed. Hope someone can help. I contacted Tech. Support but all they said was check the settings. As far as I can tell the settings are the same. Thanks.

Welcome to the forums,

There are 2 figures that VS burn module displays. One is the amount of Free hard drive space needed, and the second is the amount of disc space. Depending on the file types, and if you're using VSP (project files) in the burn module, VS may not correctly interpret the amount of space needed.

Also check the bitrate for the Project Settings in the Burn module. The higher the bitrate, the larger the file size, so more disc space will be needed. To fit 1½ hrs on a SL SD DVD you would need to use a bitrate of about 4000kbps.

If you're proceeding into the burn module from the editor with files in the timeline of the editor (Share>Create Disc), you might try to first create a video file from your project (Share>Create Video File), then clear the timeline by selecting File>New Project. Now open the burn module and insert your newly created video files, which should be DVD compatible MPEG-2.

Hi
The bit rate (data rate) used to create the video file controls the size of the resultant file.
A bit rate of 8000Kbps will produce a file of about 4.3 Gb for a 60 minute video.
A 1 hr 30 min video would end up as 6-7 Gb, about the size you are seeing.
If you require 90 minutes to fit a disc then you have to reduce the bit-rate to about 6000kbps.

Check your project properties bit-rate.

Share Create Video File¡Xselect an option
You can view the properties used to render the video in the lower panel (Properties)

You may be best using Tools-Make Movie Manager to create your own templates, that way you will always use the same settings to render your video¡¦s.

A bit rate calculator may help in deciding your settings. At least its worth a read.

Thanks for your responses. I burnt the project in another program. I am about to try another one and I will try your suggestions. Thanks a lot.

I burnt the project in another program.

And don't think that is an unusual step. Many people, me included, use other software to burn the project. In VideoStudio I create DVD folders then use Nero to burn. I do it that way because I may want to come back and burn several more copies, and Nero gives me more flexibility than VS does.
