VideoAnalyzer by Rein Haljand

User Instructions

1. Starting the Application

1. Double-click the VideoAnalyzer icon to launch the application.
2. Open the Main Menu (upper-left corner).
3. Select Open New Video File.
4. Choose the video file you want to analyze.

After opening a video file:

• The first video frame is displayed.
• Upper-left corner: timecode (00:00:00.00), frame number, FPS and video resolution.
• Upper-right corner: ClipInfo button (show / hide FPS and resolution).
• Top bar: video clip name.
• Bottom row and right column: function buttons.

Button colors:

• Light blue – active
• Light gray – inactive
• Dark blue – selected function

2. Activating Measurement Functions

Measurement functions (distance and speed) require scaling.

1. Press Set Scale (right side, bottom row).
2. After scaling is completed, measurement buttons become active (light blue).

Button behavior:

• Click once to activate a function.
• Click again to stop the function and save the result.
• Activating another function automatically stops and saves the previous one.
• Hovering over a button displays a tooltip describing its function.

3. Saving Your Work

To save all measurements, drawings, graphs, and text:

1. Open Main Menu
2. Select Save Analyzer File MJPEG2
3. Wait until saving is complete

Saved file types:

• Analyzer file (.mjpeg2): contains the video with all measurements; can be opened only with VideoAnalyzer by Rein Haljand.
• Analyzer picture (PNG): saves the current screen with drawings and data.
• Measurements file (CSV): can be opened in Numbers or Excel.

Saved analyzer video files can be reopened anytime using:
Main Menu → Open Analyzer File MJPEG2

4. Race Analysis Without Scaling

For Race Analysis, scaling is not required, because all data is based on time.

Predefined distances include:

• Start – 15 m
• Turn – 5 m in + 15 m out
• Laps – 5 m, 10 m, 25 m, etc.

5. Application Information and Exit

• Click VideoAnalyzer by Rein Haljand to view program properties, version information, license and copyright.
• Exit using the red window button.
• If the application does not close, use Force Quit.

6. Video Controls and Keyboard Shortcuts

Playback controls:

• Play / Pause
• Slow motion forward
• Frame-by-frame forward / backward
• 5-frame forward / backward

Keyboard shortcuts:

• Space – Play / Pause
• Q / W – 1 frame backward / forward
• A / S – 5 frames backward / forward
• Z / X – Jump to beginning / end
• R – Slow motion
• B – Show / hide scale targets
• P – Show / hide progress bar
• F – Show / hide all function buttons

Tip: Use your left hand for keyboard shortcuts and your right hand for the mouse.

7. Stroke Rate and Kick Rate

• Stroke Rate (SR): click SR or press K; mark the same arm position at the beginning and end of one stroke cycle.
• Kick Rate (KR): click KR or press L; mark the same leg position at the beginning and end of one kick cycle.

8. Time Control

• The clock displays minutes, seconds, and hundredths.
• TimeZero sets the selected frame to 00:00:00.
• Used mainly for race start signals.

9. Scaling Procedure (2.5 m)

Scaling is required for distance and speed measurements.

General rules:

• Scaling defines how many screen pixels equal 2.5 meters in real distance.
• Use a 2.5 m scaling stick, or a scaling rope with 2.5 m markers.

When scaling is needed:

• Fixed camera (start jump, side view)
• Moving underwater camera on trolley

When scaling is not needed:

• Front or rear views
• Pure race-time analysis

10. Scaling with Fixed Camera (Tripod)

1. Record a short scaling clip (2–3 seconds) without a swimmer.
2. Place a 2.5 m stick horizontally in the center.
3. Activate Scaling.
4. Left-click and drag between the two scale points.
5. Right-click to transfer the zero point.
6. Go to the last frame and right-click on the same reference point.

Important:

• Deactivate the scaling button.
• Save the analyzer file immediately (.mjpeg2).
• Do not touch scaling again.

11. Scaling with Moving Camera (Underwater Trolley)

• Place a marked scaling rope (~2 m deep) in the center of the lane.
• The swimmer must swim directly above the rope.

Procedure:

1. Begin scaling when the camera starts moving.
2. Measure the first 2.5 m using left-click.
3. Use right-click only to transfer zero points.
4. Transfer before each marker disappears.
5. During turns, continue transferring when camera direction changes.

After scaling:

• Rewind and verify accuracy in slow motion.
• If incorrect, quit and repeat scaling.

12. Analysis Functions

Drawing tools:

• Text (Tx)
• Arrow
• Rectangle / Ellipse
• Line
• Spline
• Angle
• Time Stamp
• t+ (multiple intervals and total time)

13. Measurement Functions (Scaling Required)

• Horizontal and vertical reference lines
• Stroke and kick pattern analysis (P1–P4, PP)
• Speed and distance measurements (V, S, VT, VS, VST)
• Accumulated measurements (V+, S+)

14. Bottom Menu Controls

• Mute created sound / background sound
• TimeZero
• Mirror view
• Undo last object
• Delete drawings (scaling preserved)
• Move and drag objects

15. Race Analysis Workflow

1. Open original file
2. Identify swimmer lane
3. Set TimeZero at start signal
4. Go to finish frame
5. Set Result Time
6. Measure reaction time, start, turns, laps, finish, stroke rate, kick rate

All data is synchronized with video playback and saved permanently.

16. Split Screen and Full Pool Analysis

• Use Split Screen to compare swimmers or races.
• Use Zoom and Drag for full-pool analysis.
• Lines remain fixed regardless of zoom.

Final Notes

• Scaling must be in the same plane as swimmer movement.
• The swimmer must swim in the center of the lane.
• Incorrect positioning produces incorrect results.
