Setting Command-Line Parameters in Fas
M
otion
Several of the operating parameters of FasMotion are set from the command line using arguments or
switches. The easiest way to change these parameters is to edit a FasMotion shortcut:
1. Select a shortcut for Fas
M
otion. This can be the desktop shortcut made by default during
installation or one that you make manually after installation. You may wish to pin the Fas
M
otion
shortcut to the task bar and use that shortcut.
2. Right-click on the selected FasMotion shortcut, then
right-click again on “Fastec FasMotion,” and click on
“Properties.”
3. Arguments may be added to the “...\FasMotion\
FasMotion.exe” line to change application parameters.
-S The “Stats” Switch
One important consideration in optimizing your system is
how to compile results.
Adding “-s” to the command line as shown in Figure 7-10,
tells Fas
M
otion to write a the file “Stats.txt” into your .../
Documents directory. This creates one line of tab-delimited text for every Save or transfer done to PC
media (such as Save or Copy to Path) by Fas
M
otion. Tab headers for this text file include:
•
Duration -
total time of the transfer (h:m:s:decimal)
•
Bytes -
the number bytes transferred
• Speed
- transfer speed in MB/s
• Missed Frames
- frames missed in the first pass (these
are retrieved at the end of the transfer)
• Good Frames
- total number of frames transferred--this
should match the number of frames in the clip
• PktSize
-Packet Size (default is usually 1500, Jumbo
frames may be up to 9000)
•
PktDlyBegin/End
--Packet Delay (the delay time in
m
sec
set in the Camera Find window)
•
Buffer
- number of buffers reserved in PC memory
•
Backoff
- FasMotion keeps track of how much memory
it is using for buffering images. If it uses more than
the specified “Backoff,” it will tell the camera to stop
sending image data until it catches up
• Min-
-Minimum Buffers (the minimum number of
buffers FasMotion had in reserve during the transfer. If
this number gets down to 0, you will see a number in
the “Missed Frames” column and you will notice in the
Save dialog that the system had to go back and retrieve
missed frames after the first pass.)
• Drv
-Drive (the target drive letter such as E: or C:)
•
Ext
-Extension (the file type saved)
Table 7-1 on page 72 is from an actual benchmark test of an optimized system. The performance,
which included saves of full (8GB) camera buffers of all file types in 1280 x 1024, 1280 x 720, and 512
x 512 resolutions, is representative of a very fast purpose-built system. A raid array used for storage is
capable of unusually high sustained transfer rates. Table 7-2 on page 72 is from a benchmark test of
a moderate-performance system.
