Captures a
series of video frames into a stack. Before using this command, you
must first create a rectangular selection in the Camera window. The
size of this selection determines the width and height of the stack
that will be created. A dialog box allows you to specify the number of
frames and the capture rate. The capture rate is specified by entering
either the inter-frame interval (Seconds/frame) or the frame rate
(Frames/second). Set the inter-frame interval to zero for the fastest
capture rate. After NIH Image
has completed recording the movie it will compute the actual frame rate
and display it in the Info window. If the computed and desired rates
are not the same then the frames were probably captured at uneven
intervals. In the case, specify a slower rate, use a smaller selection,
or try enabling 'Blind' Capture. Type command-period to abort the movie
making process.
'Blind' Capture Disable screen
updates, allowing faster frame capture rates.
Buffer Capture Use uses the LG-3's expandable buffer memory to store the
frames. When combined with blind movie capturing, this enables
capturing at video rates. The software limits the number of frames in a
movie to the number which will fit in the LG-3's memory buffer (this is
the number of Mb on the LG-3 times two). Note that if there is a lot of
memory installed on the LG-3, there must also be a lot of system memory
in the Macintosh in order to work with the frames once they are
captured.
