Video doubles in size!

esclava · Post by **esclava** » Thu Jun 19, 2008 6:23 pm

Hello again!

I'm having a problem with videostudio doubling my project!

If I capture from a DVD/Folder, and the video is over 3 hours and the size is 6.73GB, I know that I have to break the project into 2 parts in order to fit it comfortably on a 4.7GB DVD.

So I import the DVD folder. When it's displayed in my library, the properties accurately say that it's 6.73GB. That's good and normal. But then, when I'm finished editing the movie or making my custom changes, I go to the DVD share tab and the project size goes from 6.73GB to double that. I thought maybe it was an error, so I cut it in half and burned my .iso. It was the worst quality ever. It looked like an overlayed project. And when you cut it in half, it goes down to the original size!

BUT I found a solution. It's an extra step and I'd like to get around it. I burn out my project as a video file (same as proj. settings) and then add it as a video file in the share tab. It doesn't double that way.

But I'd still like to avoid this extra step.

Please, am I doing something wrong? Is there a setting that I'm overlooking? I've never had this problem before!

Thanks,

Sounds like you have a setting wrong.

What are the properties of the original clip? (right click on a clip in the library and post here)

What are the properties of your project? (File>Project properties - post here)

What are your burn properties? (from the burn window will see a cogwheel icon in the lower left - click and post the properties here)

Hi

First of all there is no extra step.

When you burn a DVD a compatible mpeg 2 file must be used..
There are two ways to achieve this,
1 /
You allow VS to render the project in the burner module, this can be seen as the ¡¥Create Title step¡¦ within the blue progress bar immediately after hitting the Burn button. The resultant video file being saved to the working folder, it is then used to burn the dvd.

2 /
You use the Share Create Video File option, select the correct properties and create an Mpeg2 file. This file is saved to the hard drive.
The file is then used in the Share Create Disc¡XAdd Video, but this time the ¡¥Create Title¡¦ step is not required.

Each of the above methods use the same amount of memory for the video files.
Each of the above methods take the same amount of time.

Ok

So that¡¦s how it should work,

as Jeff has said ¡¥Sounds like you have a setting wrong.¡¦

As you imported from a DVD Folder your file should be an Mpeg. Normally you should try to maintain the same properties as the original video clip through-out the editing and burn process.
What are they?

Also are you using Duel layer discs?

Here are the clip properties when I view them in my Windows folder:

When I view them in my Ulead Library:

When I view them from File > Project Properties:

And when I view them in the cogwheel Share tab:

The reason this puzzles me is because I have successfully created over 50 DVD projects. I've done this same procedure many times, but I've never experienced this doubling scenario yet. I have not changed my project settings at all. I wonder if maybe videostudio is getting confused when I import a 6.73GB file. I don't know.

And the extra step I was referring to¡K

Normally this is my procedure:

1. Import DVD folder.
2. Edit that .mpeg file (that ulead already converted)
3. Click on the Share tab
4. Select the DVD 4.7GB Disc/Aspect Ration 4:3 option
5. Auto insert menu markers and no menu
6. Determine final output location for .iso
7. Let it render/burn project for 1&1/2 hours

Of course, if you were to time the whole process, you¡¦d probably end up with the same hour and a half, but what I call my ¡§extra step¡¨ is my involvement with it.

1. Import DVD folder.
2. Edit that .mpeg file (that ulead already converted)
3. Click on the Share tab
4. Create video files > same as project settings
5. Let it create .mpeg file (it takes about 25 minutes depending on size)
6. Open new project
7. Click on Share tab
8. Select ¡§Add video files¡¨ and auto insert chapter markers and click next
9. Determine final output location for .iso
10. Let it render/burn project for 1 hour

I don¡¦t have a program on my pc that converts .mpeg files to .iso images.

Hi

I do not understand the figures just don¡¦t add up.

A video file using 9400kbps for one hour will produce a file of approx 4 Gb, this will fill a single layer disc.

Your video is 3 hours and at 9400 that¡¦s 12 Gb.

The readings in the burner module showing 3 hr 2 min 35sec at 12.32Gb seems correct.

If you reduce the bit rate to about 3000kbps then 3 hours may produce 4 Gb and fit to disc.

So how did you import your video?
Was it a duel layer disc?
Was the dvd re-coded during importing

Confused

PS on the Project Properties image you dont show the Bit Rate???

Right! The key file size is bitrate (and playing-time).

File Size in MB = (Bitrate in kbps x Playing Time in minutes) / 140

To you use that formula, use the combined audio and video bitrates. And, if you are using variable bitrate, use the average bitrate (of course).

The formula gives you a very close approximation, but it's not exact because it does not account the file header or any other file "overhead", and there is some rounding.

The formula works for any format (including MP3 files), because it's simply a matter of scaling-up from kilobits-per-second (kbps) to megabytes-per-minute.

Well, I thought I'd just let you know that even though it may look like I'm having the normal thing happen with me on the doubling of my video (it's kind of hard for me to explain to you what's really happening) it's not normal. I matched the settings and everything from project to project - I actually think the trouble is coming from my original DVD. It's single layer 4.7GB, so I think 7.6GB is way too much to crunch onto it!

But I thank you for your help! I did some testing and I found out my "new" method is really is a timesaver in the long run.

Thanks again!

Hi Esclava
I agree its not normal

As your original disc is a single layer, the total size cannot exceed 4.7 GB unless the import process is re-coding the video.

How are you importing the DVD.?

Ok Try this

Your DVD contains VOB files, usually called
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB

Each being approx 1 Gb except the last which will be smaller. These files contain your video.

Copy these to your hard drive then insert to the timeline, say yes to the info window.

What are the video properties? The Bit Rate!
