Long version:

PHYSICAL SETUP

CAMERAS

Place the laptop on the Referee table. The referee table needs AC to power the laptop. Plug in the following USB peripherals to the laptop:

  1.    Mouse
  2.    Connect the camera 1 (Microsoft Lifecam) to left side USB port
  3.    Connect the camera 2 (Logitech Webcam) to right side USB port
Do not connect the cameras on the same side of laptop. Do not use USB hub.

TRIPODS

Mount the cameras to the tripods.  The best tripod height is about 3 feet or waist height.  The height can be around table height (29 inches) or below.  Do not overbuy on tripods.  Nice, sturdy, heavy  tripods are unusable for CARE; too heavy to transport.  The CARE cam hardly weighs 1 pound.  You can use lightweight tripods. 

USB CABLES

The USB cables run under or along side the edge of the mat.   Avoid daisy chaining the cables.  Dainy chaining means connecting many cables. The male side to laptop, and female side to camera.   



   

DIFFERENT CAMERA ANGLE








USB cable goes under the mat
Green dots:  Cameras on Tripods
Blue box : Referee table
Red line:  USB cable that goes along the edge
Green line: USB cable that goes under the mats
Important thing here is:  male side of cable to the referee table, female side to the camera.


MULTIPLE MONITORS

If you are using CARE operator, the CARE should be used with a 2nd display pointing to two judges.  Your laptop will have VGA or HDMI output.  Please use a correct monitor (19 inches or larger) and connect to the laptop's  2nd display output.   Use DUPLICATE instead of EXTEND in 2nd display setup.  


How to set up your screens
Once you plug in your screen, you can choose your display options.  Right click on the screen to change GRAPHICS PROPERTIES.

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. 

This photo is showing EXTEND.   Kinovea and windows file explorer on the laptop screen and PotPlayer on the large screen. 
  


MOUSE

Mouse use during CARE is minimum.  
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 is used.

WINDOWS FILE EXPLORER BEST PRACTICE

Create a folder in C: drive root.  For example, c:\judocare videos or C:\mat2day2
Do not create a folder on DESKTOP. It bogs down the laptop.

How to configure the Kinovea to point to the new folder. 

Go to Kinovea  >  Options > Preference > Capture > Video directory 
Find the new folder to associate the new folder to Kinovea


Open File Explorer.  Date sort the files in descending order so the newest file is always on the top.  

POTPLAYER BEST PRACTICE

You do not need to independantly run PotPlayer.  Double clicking on a video file will bring up PotPlayer automatically.  
PotPlayer is where you can review the instant replay 
PotPlayer has built-in 6 seconds delay so don't add delay in Kinovea if you are streaming to PotPlayer.  



PotPlayer configuration: 

Start PotPlayer
Right click anywhere on screen to bring on PREFERENCES (F5). 
General > Multiple Launching > Play the clicked file
Playback > Time Jump > Left/Right arrow key (3 seconds for keyboard, 1 second for wheel)

This is 2nd Monitor.  Notice Potplayer on the left, and windows file explorer on the right.

Space bar: start/stop
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)


KINOVEA BEST PRACTICE


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.




Do not worry about NEXT IMAGE field
Do update NEXT VIDEO field:  Left-1 or Right 1 to start. (or Front - 1 or Back -1)
Left side delay  = 2 seconds  
Right side delay = 4 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 or not recording. 
Small Red dot means it's recording


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:

CARE RECORDER

Turn on the laptop
Click on CARE user (no password)
Run Kinovea

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.  If you pump up the resolution, you will bog down the laptop. 

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.  

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 should archive the old video files out of the laptop's C: drive.  Most videos are about 1gig in size.  100 matches a day = 100 gigs.  You can do the math on how quickly the C: drive will fill up.

Double click the video file to view.

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.


CARE PLAYER

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.

 (print this template 8 1/2 x 11)



CARE PLAYER CONTROLLER



DISCONTINUED: The multimedia wheel works on CARE potplayer only. It does not work on CARE recorder Kinovea. You can configure to work on CARE recorder, but I haven't found it useful on CARE recorder.

GEEKS ONLY

Hello fellow geeks with awesome moves and gadgets.  Please heed this rather blunt advice.  Please do not geek out with CARE laptop.  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.  Keep your expert opinion to yourself.  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 a tool to help make sure the right player gets the win.  It's not for our amusement.  Resist this temptation.   Thank you.
