2.7.2 Processing File Video
These are the available options when the video being processed comes from one
or more files.
2.7.2.1 Frame Rate
This is a display-only field showing the frame rate at which the video file(s) were
recorded.
2.7.2.2 Speed
This adjustment determines the speed at which CinePlex Studio will attempt to
create the new video file(s). It does not change the frame rate of the video. This
speed will ultimately be limited by the capabilities of the computer on which it is
installed.
2.7.2.3 Position
This is the frame number from which recording of new files will start. It can be
changed by adjusting the slider which can be placed anywhere within the file,
once a file has been selected on the Source pane.
2.7.2.4 Compression
Any new files that CinePlex Studio creates will always be encoded in MPEG format
as defined in the applicable MPEG specification document. MPEG file sizes
and quality vary with the nominal compression bit rate. The higher the bit rate,
the higher the resulting video quality, but the resulting AVI files are larger as
well. In CinePlex Studio the MPEG Quality is adjustable fro 1 to 10. The larger
the value selected, the larger the resulting AVI file will be, but it will have better
resolution. Adjust this number to obtain acceptable results for the experiments.
The value defaults to 4, a value Plexon has found to be a good compromise in
most situations. For reference, the selectable values correspond to the MPEG
nominal bit rate divided by 500,000.
2.7.2.5 Experiment
The only currently available experiment adjustment is a selection as to whether
the experiments involve one animal or more than one. Make the selection “Single”
or “Multiple” appropriately. The effect on CinePlex Studio is to change the
way it searches for multiple colors or LEDs when tracking is lost momentarily.
