Using the Enhanced Video/MPEG Features

The Enhanced Video feature provides the video overlay/capture and MPEG functions and video in-out port on the side of the computer to attach your home video equipment. It also provides the total image video with MPEG-1 and MPEG-2 HHR (half-horizontal resolution).

With the Enhanced Video feature, you can take advantage of the following:

MPEG playback: The MPEG playback viewer can play back many available CD-i movies, video CDs, and karaoke MPEG video titles. No DOS/CD-i game titles are currently supported. MPEG2 titles are restricted to HHR at 4 Mbps.
Video-in (video capture):
- Capture still images or motion video from the video-in port.
- Overlay motion video from the video-in port.
Video-out: To use the video-out function, see "Attaching a Television to the Computer".

(Ref #42.)

When using the video overlay/capture and MPEG functions, keep the following in mind:

You cannot enable or disable the Enhanced Video feature, or change from video-in to video-out, while the playback or capture window is open. Close the playback or capture window before you make changes.
The MPEG playback and the video-in (video capture) functions use the same hardware resources. Only one of the two functions can be used at the same time. For the same reason, two MPEG functions cannot be used at the same time.

Using the Video Overlay/Capture and MPEG Functions for OS/2 Warp

This section describes how to use the video overlay/capture and MPEG functions in OS/2.

You need at least 12MB of memory to play MPEG or to capture video from the video-in port using Video IN.
When reinstalling the video overlay/capture and MPEG device drivers, install Video IN from the BonusPak, preloaded on the computer, prior to the device drivers.
When the Enhanced Video feature is enabled by the ThinkPad Features program, and any of the following is being played or used, do not enter suspend mode:
- AVI file

Using the Digital Video Producer for Windows

Digital Video Producer (DVP) is an application program that has the following functions:

Capturing, compressing, and building a video file
Capturing a still image (see reference #43)

Capturing, Compressing, and Building a Video File

This sample procedure describes how to capture a video clip, import it to DVP, and build a compressed .AVI file that you can use in a presentation and other computer-based materials. The video file created in this example has the following characteristics. (You need approximately 17MB of hard disk space to capture a video file.)

Frame size: 160 pels by 120 pels
Frame rate: 15 frames per second
Number of seconds: 30 seconds
Audio sampling rates: 8-bit, 11.025 kHz, mono

Important
Make sure your video source (such as a VCR or video camera) is correctly connected to your computer before you start the video capture. If you select overlay mode from the Options menu in DVP Capture, you can verify the connection and look at your video both before and during the capture.

To capture, compress, and build a video file:

Start DVP; then select Video Capture from the Tools menu.
Select Set Capture File from the File menu.
Enter a name for your capture file (such as CAPTURE.AVI) and specify the directory in which to save the file; then click on OK.
Select Allocate File Space from the File menu and enter 17MB as the hard disk space to set aside for your capture file; then click on OK.
Select Audio Format from the Options menu.
Select these sound options: 8-bit, 11kHz, and Mono. Then click on OK.
Select Video Format from the Options menu.
Select 160x120 for Image Dimensions and Overlay YUV422 or Compressed YUV422 for Image Format; then click on OK.
Select Video Source from the Options menu, the type of video connector your video source uses (video or S-video), and the type of video signal (NTSC or PAL).
To see the supported color standard list of countries, see the ThinkPad Features program help.
Select Settings from the Capture menu and specify the following options:

Frame Rate
15 frames per second
Enable Capture Time Limit
30 seconds
Capture Storage
Capture to Disk
End Capture Using
Escape Key
Check Capture Audio; then click on OK.
To start the video capture, select Video from the Capture menu.
DVP Capture saves the file with the name you specified in step 3. You can then save the file to a new name by choosing Save Captured File As from the File menu.
Select Exit from the File menu to close DVP Capture and return to DVP.
DVP automatically imports the video file you just captured and displays it in the Media window.
Drag your video clip from the Media window onto the tick bar (directly above the video A track on the timeline).
Dragging a clip onto the tick bar is an efficient way to lay out your clip because the video and audio information in the file appears automatically on both the video A and audio A tracks. You can also lay out a video clip on the timeline by dragging it first from the Media window to a video track, and then from the Media window to an audio track.
Select Compression from the Video menu to specify the compression/decompression (CODEC) routine you want to use.
Select Intel(**) Indeo(**) Video R3.2 for Compressor and accept the default values for Key Frame Every and Data Rate; then click on OK.
Select Build from the Video menu. Enter the name and location of your final .AVI file (making sure to keep the .AVI extension); then click on Build.
The Build Progress dialog box opens, so you can look at the percentage-complete bar and the preview window to track the progress of the build. Building a video can take anywhere from a few minutes to several hours, depending on its length and complexity, and on the type of compressor you select.

Capturing a Still Image (Ref #43.)

This section describes how to capture a still image.
Important
Be sure your video source (such as a VCR or video camera) is correctly connected to your computer before you capture the still image. If you select overlay mode from the Options menu in DVP Capture, you can verify the connection and look at your image before you capture it.

Important
Be sure your video source (such as a VCR or video camera) is correctly connected to your computer before you capture the still image. If you select overlay mode from the Options menu in DVP Capture, you can verify the connection and look at your image before you capture it.
