## What is Motion Marker?

Draw directly on your videos and explain instantly. 
Compare two videos side by side for in-depth analysis. 

Motion Marker is a professional video analysis tool for 
sports coaches, dance instructors, and stage directors.

--- DRAW DIRECTLY ON SCREEN ---
Annotate any frame with lines, arrows, circles, and freehand 
drawings. Highlight movement paths, formation patterns, 
or key positions without switching to another app.

--- DUAL VIDEO PLAYBACK ---
Load two videos side by side and play them simultaneously. 
Compare a reference performance with a student's recording 
in real time -- instantly spot the differences that matter.

--- DRAW DIRECTLY ON SCREEN ---
Annotate any frame with lines, arrows, circles, and freehand 
drawings. Highlight movement paths, formation patterns, 
or key positions without switching to another app.

--- PRECISE ANGLE MEASUREMENT ---
Measure joint angles, limb positions, and formation geometry 
with accuracy. Communicate corrections with numbers, 
not just words -- "raise your arm to 90 degrees" 
instead of "a little higher."

--- FRAME-BY-FRAME CONTROL ---
Pause at any moment and step through footage one frame 
at a time. Never miss a critical detail in fast movements 
-- whether it's a soccer kick, a cheer jump, 
or a stage entrance.

--- BUILT FOR EVERY COACHING DISCIPLINE ---
* Sports Coaches -- Analyze formations, player positioning, 
  and technique in match or practice footage.
* Dance & Cheer Instructors -- Compare routines side by side, 
  measure arm angles, and track synchronization.
* Stage Directors & Choreographers -- Review blocking, 
  entrances, and movement flow with visual annotations.

Upgrade to Motion Marker Pro to unlock 
dual video playback, angle measurement, 
and unlimited annotation tools.
