Hi,
I just need a little advice on compression. Im using VideoStudio 9 and trying to find the right compression settings to make a DVD. Basically, my freind has a DVD full of little movies that add up to about 3h 30mins with excellent video quality. So what I want to do is add these movies into VideoStudio with a little menu (which is now complete) and fit it on a DVD. But its way too big. I have tried different settings in "project settings" The only way I can get it to fit is at variable 2500kpbs which from what Ive read isnt very good quality for DVD. I dont know how 3h30mins of video has been compressed on a disc. Can someone help me out?

Hi
As a guide using:-
8000 kbps bitrate will get 60 minutes top quality to one dvd.
6000 kbps bitrate will get 90 minutes very good quality to one dvd.
4000 kbps bitrate will get 120 minutes Vhs quality to one dvd.
If your movies have already been saved to disc. Was the disc a dual layer or single layer disc?
I assume the movie clips are saved as mpegs as a data disc.
Using a bitrate calculator does indeed give about 2500 for a 210 minute movie.

First of all check the properties of the movie clips.
Insert one in the timeline – right click and select properties, what are they?

thanks,
The disc is single layer.

Hi
Your video properties look spot on to me.
What I don’t understand is how you managed to get 3hrs 30 mins at 8000 kbps onto one disc.
The size of this should be about 12 Gb.???????????
Or am I reading it wrong. I think you may have re-coded the original when you inserted the movie into your pc??????????
Ok
So how did you get the video files onto your pc?
Assuming this was ok you need to re-code / render the video clips to fit a disc.
The best way is to create your own templates.
Tools-Make Movie Manager – Add—File Path--browse your hard drive for one of the mpegs—insert a template name-OK
You have now created a template to the properties of your movie file.
But you need to change the bit-rate
Select--Edit—Compression—change the video data rate only to 2500. (or whatever)
You now have a template identical to your movie settings except for the bit rate.
The template will be available in Share Create Video File, near to the ‘custom’ option
The data rate you chose determines how many minutes you can fit to disc. (this is your option)
I would split your movies in half and use two discs, again that’s your choice.
Use the bit rate calculator.
With your movie clips in the timeline, Share Create Video File—select your template.
Give the new file a name.
The process is called rendering and will take a long time.
As a guide 2.5 times the run time.
So for a 3.5 hr movie its going to be long, 8-9 hrs or so!!!!!
You have the option of rendering each movie on its own or creating one file by inserting all the files to the timeline.
Hope this helps

Ok, thanks for the help...
All I have done is selected Tools>create disc, then import dvd and selected the titles.
There are 5 in total, around 40mins long each and when I drag just one into the timeline, it is 2.4gb.
So, is this because they are already rendered for a dvd?
If so, do I need to convert each one back into AVI, then re-code / render ?
Also, would I have to pick out the correct codec and audio settings when converting back to AVI?
Sorry for being stupid

based on the size and time you gave, the file is encoded at about 2600kbps (the 8000kbps is not the avg. bitrate of that video).
Make sure you select "Do not convert compliant mpeg files", and just create your dvd.
Try it with the video you selected, and output the dvd to dvd folders on your hard drive -- it should end up about the same size as the video file (don't use motion menus).
If all the files have the same properties, then they should be already compliant and you could just use them "asis"...

Hi Sas
I am not sure I am understanding what you are trying to do with the Dvd.
If you need to edit the movie then you have to import the files to the edit timeline.
If you just want to create a new menu, then import as you are doing but change the project properties to match your video file. ( I have not used this approach)
Right click a clip in the timeline select properties, make a note of them.
Now click the ‘cogwheel’ lower left, select change Mpeg Settings—Customize—Set your properties to match.
If you want to edit your video files.
Start a NEW project.
Click the lower left folder icon and select ‘Insert DVD/DVD…
Browse for the dvd TS folder and insert the selected titles.
This will place your video in the timeline, and save your files to the working folder.
Here you can edit and add titles etc.
Then share create video file—same as—first clip
The resulting file being used in the Share – Create disc –add video

Glad you got everything to work...
But if you only wanted to add a small menu that you created (is that a menu, or video btw?), you might have been able to save some time by avoiding any re-encoding of the original video assets -- so you would have the same quality as the original.
How large was the media you were trying to add? Or was it just a menu?
You go to the Share/Create Disc, and import a video. Then make sure you hit the cogwheel in the bottom left corner and select "Do not convert compliant mpeg files" (if you don't want to re-encode the audio you are working with based on your earlier post, leave the checkbox open on the other option that says "Treat mpeg audio as non dvd compliant").
Output the video to DVD Folders on your hard drive -- this process should go pretty quickly if it does not re-encode your videos (also assuming you are creating an NTSC DVD like your originals). Try it as a test just using one of the smaller videos from your original dvd -- just to see how the process works, and how much faster the dvd build process can be by re-using the original compliant videos "asis"...

It was a NTSC disc that I wanted to convert into PAL and also add a little menu so the media had to be re-encoded.
When I added one movie it read about 2.5gb, so in total it was about 11-12gb
That was what I didnt understand. But like I say, I re-encoded the whole lot added a little menu and Im quite pleased with the result although it isnt as good as the original.

aha -- that's why I added my comment about assuming you were creating an NTSC DVD (just in case you were actually doing a standards conversion) -- and that would explain why the entire lot had to be re-encoded...
Glad you got it working...
