VIDEO CAPTURE: CHAPTER TWO 107
4.
Click OK. If you selected Auto as your capture option, Video Capture
begins capturing frames at the specified rate. If you selected the
Manual option, the Manual Capture dialog box opens with two buttons,
Next and Cancel. Click Next to capture one frame: Cancel to end the
capturing.
When the capturing process is completed, a palette is generated from the
optimum combination of colors based on the captured frames. Once
defined, the color palette is stored in memory until you capture a new
color palette or close Video Capture. If you wish to save the palette for
later use, click Palette: Save Palette. To load it back into a video
sequence, click Palette: Load Palette.
Note: You can also copy and paste palettes using the Palette: Copy Palette and
Paste Palette commands. (These commands are disabled if the active video is not
Indexed-256 Color or the data on the clipboard is not palette data.)
Changing a file’s properties
Whenever you capture a video sequence, you must first specify a file in
which to save the resulting video. There will be times, however, when you
wish to save this video again to change its attributes, such as frame rate or
the compression scheme. (This is particularly true if you have a hardware
compressed file, such as MJPEG or MPEG, and you wish to play it back
on another machine which does not have the same hardware setup.)
Being able to accurately pinpoint frames also gives you more flexibility in
editing video. For example, you can first capture your video as low
resolution files and therefore have them occupy much less disk space. You
can then edit them considerably faster in Video Editor and, when ready to
compile the final version, you can recapture the exact frames at a higher
quality. (You can also import the DVP file from Video Editor, including any
edits you have done, and have the device capture the original video based
on your edits.)
