Pelco C2631M-A manual Exporting a Sequence of Still Images, Finalizing AN Export Process

EXPORTING A SEQUENCE OF STILL IMAGES

Still image formats export the first frame of a bookmarked region, and then a single frame for each time interval until the number of images specified has been exported. For example, consider exporting a six-hour bookmarked region of video with an image count of 100 and a time interval of 3 seconds. The resulting export will include the first frame of the bookmarked region followed by 99 additional images taken at three second intervals. The first exported image will be the first frame of the bookmarked region and the last image will be the frame taken at

300 seconds into the bookmarked region.

To export a sequence of still images:

1.Select a still image format. Options are BMP, JPEG, and TIF.

2.Select the number of images (1-999) you want to save in the sequence.

3.Select the time interval between each saved image in the sequence. Options are as follows:

•Continuous

•0.5 seconds

•1 second

•2 second

•3 second

•4 seconds

•5 seconds

FINALIZING AN EXPORT PROCESS

This section describes how to finalize an export process. The following guidelines are applicable:

•Audio export is available only with DX8100 native, AVI, and ASF video formats.

•Real Time setting applies only to DX8100 native, AVI, and ASF video formats.

•When the Real Time check box is selected, the DX8100 will export video so it can be played back in real time (30 fps) for the same length of time as the original recording. For example, if video was recorded at 1 fps, this means the DX8100 will insert 29 null frames for every one frame of actual video. Thus, one minute of video recorded at 1 fps (60 frames total) will play back for one minute at 30 frames per second (60 frames of actual video interspersed with 1,740 null frames). If the Real Time check box is not selected, one minute of video recorded at 1 fps will play back in two seconds in real time. Figure 87 illustrates the two video streams: 1) one padded with null frames to match the actual time duration and 2) another stream without null frames.
