Setting Up the Project

Previous Top Next |
You can start out the same way as when doing live capture by entering a Project ID, title, subtitle and date for the project.

Selecting the Audio and Video Files
|
|
At this time, don't worry about the capture limit because it will not be needed. Leave all four checkboxes unchecked. Now click the ![]() |
|
![]() |
|
The four text fields are the values entered on the setup page of the display. If you changed any of the text here, the change would be reflected on the setup display page.
|
|
· | Now check the 'Use Pre-Captured File' option.
|
|
· | Next click on the 'Pre-Captured Files' tab, and that property page should appear.
|
|

|
What you need to do now will depend on the type of pre-captured files you have. Select the type of files you have on your hard disc that you will be making a DVD from. Next click the 'Enter/Edit FileList' button and the following should appear.
|
|
![]() |
|
Now click cell under the Video File header.
|
|
![]() |
|
Click again, this time in the area circled in red, to get a browse button.
|
|
![]() |
|
Now click the browse button to select the video or multiplexed file.
|
|
After selecting the file and closing the browser dialog, if needed follow the same steps to select your audio elementary stream.
|
|
If you are using Elementary Streams, Program Stream or VOB Files, the video will not need to be encoded so you can close the 'Pre-Captured FileList' dialog as well as the project property page dialog. If your hardware supported Video Preview, the preview will stop when the property page is closed. This is because the application knows that this project has been setup to author pre-encoded file and will not need the video capture. Proceed to 'Start Authoring Pre-Encoded Files'.

Setting the Encoder Bitrate
|
|
If using 'AVI files or other files that need to be transcoded' the software MPEG-2 encoder will be used. One of the key settings that needs to be made for MPEG encoding is the video bitrate. The bitrate is the factor that determines how many minutes of video can be stored on a standard DVD.
|
|
· | The bitrate can be computed automatically if the length of the video clip is known. The length of the video clip can be entered in the cell under the heading 'Length (hh:mm:ss)'.
|
|
· | If the length of the video clip is not known, but you know what to set the bitrate to so that the compressed audio and video will fit onto the DVD, you may set it manually at this time. To set the bitrate, click on the 'Capture/Encoding' tab on the property page to get the following:
|
|
![]() |
|
Select the 'Manual' Bitrate Computation as shown. If your video is less than one hour and fifteen minutes long, you can leave the bitrate where it is. If your video is longer, you will have to compute the bitrate yourself. For now, ignore the other fields and click OK accept all the project settings. If your hardware supported Video Preview, the preview will stop when the property page is closed. This is because the application knows that this project has been setup to do offline encoding and will not need the video capture.
|
|
Proceed to 'Start Offline Encoding'.
