NOTE: The selection of the format does not just depend on the desired quality of the video;
consideration should also be given to how you will view the data at a later date. For instance should
you wish to view the data over the Internet then you may wish to use the lowest compression rate
available.

i.e. Composite
input.

This option is no longer available

Video Storage Format:
MPEG only
This setting will only record raw mpeg files
Pkt with embedded nav
–
With this option enabled, and a Navigation string being input to the
recorder, each MPEG file will be tagged with positioning data, this
then enables the video to be integrated in to a GIS system at a later
date.
Note:
For structural inspections there is no benefit to ticking this box
as generally there is no acoustic positioning data available.
Although certain types of software (e.g. Coabis) require the use of
pkt to enable enhanced editing features.
Maximum Segment Size:
Each section of video recorded can be broken down into discreet video clips to aid reviewing and
managing the files. These sizes of each clip can be set by time or volume of data. Should you wish
to be able to download a file to a certain type of media e.g. a floppy disc, then you would select file
size as the controlling factor and set the size to fit your disc.
If on the other hand you wish to store the video by time then select that option and put in the
number of seconds you want the file to be.
