big MPEGs into little mpegs
I've watched the videos, looked at the online help, searched the board for 'chapters' and I'm still stuck.
Let us say that we have an mpeg about 90 minutes long. I want to cut it into three roughly equal mpegs so as to be able to edit each section and later work with chapter menus. I tried using the scissors and cutting it, highlighting one section, then went to 'CLIP | Save Trimmed Video' but nothing happens. No saving no nothing.
So what is the magic key to cutting up an MPEG into little mpegs? Perhaps a little utility to cut em up?
thanks

Hi
From file preferences tick ‘show messages when inserting first video into timeline’
Use the scissors to cut your movie into three.
Drag each clip to the library, (you now have a thumbnail copy of each)
Start a new project
Drag the first thumbnail from the library to the timeline (select yes to the info window)
If you wish to edit the clip further add titles or fade to a colour at the end
Save the project
From Share--Create Video File—same as project settings
Select a name and location to save the new file.
Start a new project and repeat with the next thumbnail.
Use the three files in the burner module, each clip will have a main menu which you can add chapters.

Large Mpeg to small
Is there a preferred procedure for managing this type of issue. For example I use Andrew's solution as far as cutting the file with the scissors and dragging a new thumbnail to the library but I do not save the file as individual clips preferring to leave the large file on the system with all the different libarary thumbnails referencing the original.
This has caused some problems when working with large files, particualry if there are lots of thumbnail references into a single file.
I just wondered if this method is known to cause problems which is why people physically cut the original into smaller sections?

Delboy,
I am very new at this but I tend to agree with you in leaving the file intact and just using clip pointers into it. However, when I do this there is one drawback that you didn't mention. The big one is when working on a two hour video, in the latter stages of the file, the system hangs when one is attempting to drag the slider. Sometimes up to a minute or more while it gets it's act together. Frustrating.
By doing what Andrew suggests, you work with shorter files and one doesn't get that hangup too often.
What I am doing now is to bring in the video from the tape in the approximate sections I will be working with and avoiding having to cut it up.

Increasing the problem ?
My problem with the approach offered by trevor is that it increases the workload when the product is meant to make this easy. If you add in the 'Project Management' issues I raised here :->
http://phpbb.ulead.com.tw/EN/viewtopic.php?p=5116#5116
then you have an even bigger administrative problem.
I guess there is no perfect solution, do Ulead have a 'new features' request form anywhere

Hi 2tired / Delboy
If I remember the original request:-
Let us say that we have an mpeg about 90 minutes long. I want to cut it into three roughly equal mpegs so as to be able to edit each section and later work with chapter menus.
To enable you to create a main menu on a dvd you have to use one mpeg in the burner module for each menu required, each main menu can then have its own chapters added.
The method I used is easy to understand and execute, there will be others on the forum that have their own ideas, but the object was to split the video into three.
As for increasing the workload (I do not understand what you mean.)
At the end of editing you should create a video file (mpeg) of your project, this can be very time consuming depending on your settings. At this point you could make three separate video files, this achieves both objectives.
I think the best method is to capture the video to the correct size in the first place, you would work on three separate projects, I find editing a little easier on the brain when working on a smaller project. Finally making separate video files to use in the burner section.
Using the scissors to cut the timeline is just an editing procedure and can be used to remove unwanted frames. In this case you would not need to place any clips in the library.

Trevor,
Here is where I am a little confused. After cutting up the large file, then editing each clip and saving each as a project, why go to all the time of saving each clip as a separate mpg file that could take up to several hours to complete?
I did the above and saved each clip as a project but didn't save each as a separate mpeg. Then, I opened a new project and went directly to "Share" | "Create Disk" and imported each of the 'project' files from the "Add Video Studio Project" selection. Then made the menus and saved it to 'Video-Audio' folders for later burning.
I guess the question is: Why make a separate mpeg of all of the pieces of the puzzle?

Hi
It has been reported to this forum several times of failures and poor quality dvd’s when using a project to burn.
The advice from the members is to make a video file of the project then use this file to burn.
Several other problems regarding the editing procedure from capture to burn are always being asked.
To address this the members have drawn up a work flow, You do not have to follow it but sticking to certain guidelines will save you time and make better quality videos.
The Recommended Procedure can be read from the posting at the top of the main forum page.
There are also several tutorials and guide, which are useful reading.
(PLEASE READ THIS BEFORE POSTING A PROBLEM ON THIS FORUM)
1 / I think keeping your settings the same from capture / edit to burn is the most important point to maintain.
2 / Do not burn a Dvd from the project always create a Video File.
Whichever option you select the time to complete the render process is the same.
Creating a Video File first gives you the option of viewing the completed movie on your pc, before burning.
Rendering from Avi to Mpeg will as you say take several hours, Mpeg to Mpeg should be easy, real time and faster being possible.
Your project of 90 mins cut into three, Providing your project settings match the mpeg settings, rendering one of the projects to Video File (same as project settings) should be fast.
Then when you use the Mpeg file to burn, Video Studio should start the burning process without re-rendering.
Hope this Helps

Mpeg Capture Properties:
NTSC drop frame (29.97 fps)
MPEG files
24 Bits, 720 x 480, 29.97 fps
Upper Field First
DVD-NTSC
Video data rate: Variable (Max. 5000 kbps)
Audio data rate: 224 kbps
MPEG audio layer 2, 48 KHz, Stereo
I set the drop frame counter in the ini file.
Yes Trevor,
This definitely helps. I had read the 'first' posting but it takes a little while and fooling around to make it sink in. I am starting a new capture as we speak.
I found that in order to put 100 to 110 minutes of video on a dvd it required a reduction to about 5000 variable. So, when you say that the best results are achieved by maintaining the same bit rate throughout the process, I assume that I should not capture at 8000 when I darn well know that it will have to come down in the final process.
Also, I just got my canopus 100 and so when the analog comes into the canopus and goes via firewire into the computer, it is indeed Analog video and so the upper field is first?
Now then, I can also assume that if I encode the audio in dolby when making the video file, that is going to extend the time required rather than if I just left the audio at the mpeg settings which it was captured.? (I haven't found out yet how much space is saved by using the dolby over the mpeg but over lcpm it is monstrous. )
I now understand why it is best to render each clip.
thanks for the help
