How to set up and operate CARE:
[laptop comes with easy to follow navigation stickers]
Place the laptop on the Referee table. The referee table needs AC to power the laptop and external monitor.
1) ShuttleXpress media wheel
Camera 1 (Connect directly to laptop to an USB port on the left side)
Camera 2 (Connect directly to laptop to an USB port on the right side)
Do not connect the cameras on the same side of laptop. Do not use USB hub.
Mount the cameras to the tripods. The best tripod height is about waist level (about 3 feet). Do not overbuy on tripods. Nice, sturdy tripods are unusable for CARE; too heavy to transport. Use lightweight tripods. The CARE cam hardly weighs 1 pound. They are "flimsy" so don't extend the legs all the way.
The USB cables run under or along side the edge of the mat. Use short cable for near camera, long cable for the far camera. Avoid daisy chaining the cables. If you must daisy chain, no more than two. When combining active and passive cables, make sure that connection order is correct (computer->active cable->passive cable->camera). The male side to laptop, and female side to camera.
Use "better angle" configuration whenever possible. It requires running the long USB cable under the mat. The far-camera is the one furthest from the scoring table. Sometime you have no choice, but to set up "good angle." A good angle configuration is still better than anything we've used before.
PRO: Keep it simple. The CARE setup takes 10 minutes or less.
CON: No backside view.

The CARE should be used with a 2nd display. Your laptop will have RGB or HDMI output. Please use a correct monitor (19 inches or larger) and connect to the laptop's 2nd display output. I use the laptop screen to run the recorder, and use the 2nd display for replay purpose. The CARE operator runs the laptop, and the 2nd display is pointing to the arbitrator. Use EXTEND instead of DUPLICATE in 2nd display setup.
How to connect multiple monitors to your PC
Connect another screen to your laptop
Plug a monitor into the PC’s DVI, VGA, or HDMI port, and Windows 8 will automatically detect the monitor.
How to set up your screens
Once you plug in your screen, you can choose your display options.
To set what's on the second screen
Swipe in from the right edge of the screen, and then tap Devices.
(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Devices.)
Tap or click Second screen and then choose one of these options:
Duplicate. You’ll see the same things on both screens.
Extend. Your screen is now spread over two monitors, and you can drag and move items between the two.
Second screen only. You’ll see everything on the connected screen, and the other one will remain blank.
It looks like this. Kinovea and windows file explorer on the laptop screen and PotPlayer on the large screen.
Mouse use during CARE is minimum.
The mouse is only used to get attention on Kinovea, Pot player or Windows explorer screens.
In Kinovea, mouse is used to start/stop recording (red button)
In Windows Explorer, mouse is used to open a file (double click)
In PotPlayer, mouse is not used at all. Keyboard or Media Wheel is used.
Create a folder.
Go to Kinovea > Options > Preference > Capture > Video directory to associate the new folder to Kinovea
Open File Explorere on external monitor Date sort the files (descending) It's Date sorted (descending) so the newest file is always on the top. Soon as you start recording (Front-54 and Back-54), double click on Front-54 and Back-54 to keep them open in 2nd monitor. The Kinovea screens will be tiny. We don't care because the replay will be done on the 2nd monitor.
Run PotPlayer on 2nd monitor
PotPlayer is where you can review the instant replay using left/right arrow keys.
Slow motion (X/Z) or frame by frame (D/F).
PotPlayer has built-in 6 seconds delay so don't add delay in Kinovea.
PotPlayer configuration:Start PotPlayer
Right click anywhere on screen to bring on PREFERENCES (F5).
General > Multiple Launching > Launch Multiple PotPlayers
Playback > Time Jump > Left/Right arrow key (3 seconds for keyboard, 1 second for wheel)
Stack the Front and Back PotPlayers so you can jump to them for instant review. You can add 3rd monitor
This is 2nd Monitor
Enter: Make full/small screen
Left arrow: Jump back 3 seconds.
Change time jump seconds (F5> General> Playback (click on + to expand) > Time Jump > Left/Right Arrow keys
Right arrow: Jump forward 3 seconds. Keep it down to reach the end of the file (most recent action)
D: one frame back
F: one frame forward
X: slow speed by 10% (keep pressing to go down to 0.2x)
Z: normal speed (1x)
Show Kinovea on laptop screen
Click on Two Capture Screens icon or go to View > Two Capture Screens
Select the front camera on the left screen, and back camera on the right screen.
The laptop screen points to the care operator. The operator click and unclick the red circle to start/stop recording.
Delay: 0 seconds Delay: 0 seconds
Be mindful of the file names: start with Left-1 and Right-1
In this example, Front-54 is a next file name after Front-53. Notice the red dot is large.
Large Red Dot means it's ready to record. It's another way of saying, it's not recording.
Keep the Delay Display to 0 seconds because Pot Player's 6 second delay is plenty. Any delay you set here will be added to Pot Player's 6 second delay.
When the red dot is pressed, the screen will show "Recording Started" and the red dot will turn tiny and the file name (Front-54) will turn gray. Small Red Dot means it's recording.
When the match is over, stop recording by pressing on the tiny red dot. The screen will show "Recording Stopped" and the red dot will turn large and the file name will automatically increment to First-55, the next file name.
COMPLETE DETAILED INSTRUCTIONS:
Turn on the laptop
Click on CARE user (no password)
Choose View > Two Capture Screens
1) Choose the cameras. Do this for left and right camera.
Open the Select source dialog by clicking the Select source button
Choose Logitech HD ProWebcam C920 > APPLY
Do same thing for the right side camera
Click on Properties (right side)
Choose Microsoft Lifecam Studio > APPLY
2) Choose the correct Configuration. Do both sides.
Select source button
You can experiment with different resolutions, but these are the two best resolutions.Logitech C920.: Choose 800 x 448 px @ 30 fps
Microsoft Lifecam Studio: 800 x 448 px @ 30 fps
Digital video requires approximately 200 MB per minute of footage or roughly 1 GB for a 5 minute match. This size varies depending on the Frames Per Second and Video Birate and Resolution.
60 FPS will be smoother than 30 FPS, but takes twice as much disk space and twice the bandwidth.
Higher the resolution, better the quality, but takes more disk space and bandwidth.
The recorder records AVI container and MPEG-2 ASP codec. You can later compress the video file size using an encoder.
The current recommended laptop processor, graphics chipset, and webcam can record in HD 1080 (1920 x 1080), but we use WVGA (800 x 488) for good balance in performance, bandwidth and file size.
3) Applying a delay to the stream and change the file names
To delay the display of the camera stream, use the delay slider under the main image. Some will put the left screen delay at 3 secondes, the right screen delay at 6 seconds. The logic is 1) see the action live, 2) see in left screen 3 seconds later, 3) see in right screen 6 seconds later.
I put it at 0 and rely on potplayer's built-in 6 seconds delay. The left/right screens are too tiny requiring too much concentration off of the live action.
In the morning, name the file to "Left-1" and "Right-1" Every time you start and stop the recording, the new file number will be incremented.
On the second day of the tournament, you can change the folder area or use different naming scheme: "Day2Left-1" and "Day2Right-1"
4) Chunk the recording:
The RED dot starts and stops the match. Start and stop the recording per match will chunk the file to a smaller size. AVI has 4gb file size limit.
5) The video files are saved to this folder. C:\Users\care\Documents.
You can change the location of saved images from the global preferences dialog.
You can change the format of the saved images or video from the global preferences dialog. For CARE, use AVI.
Open up Windows File Explore and go to C:\Users\care\Documents
An AVI (video) file will be created there. Just double click the file name, and Potplayer will start automatically.

Hello fellow geeks with awesome moves and gadgets. Please heed this rather blunt advice. The jury are not interested in the geeky, "cool" portion of CARE. It's weird, right? but trust me, they really just don't care. Just show the jury what they ask for on a large 2nd display (19 to 24 inches) without much ado. No explanations, no discussions necessary. Just serve up the video, and resume see no evil, hear no evil and talk no evil mode.
Don't try to add bells and whistles to make it shiny and bright. The CARE is devoid of all bells and whistles on purpose. It's optimized for speed performance. Attempting to hook up currently popular iOs or android hand held devices to network into the laptop is a futile exercise. Don't do it. I know you know how to do it. You are introducing all kinds of latency and lag and load issues. A judo action on an hand held device will be reduced to 1/4 inch action area, smaller than a postage. No jury will put up with a stamp-sized action area to make an important decision.
If you insist on geeking out with the CARE, I am sorry to say that while you are very smart and cool, you've forgotten the essence of CARE; it's just a tool to help make sure the right player wins. It's not for our amusement. Resist this temptation.
