====== Panels ====== 

===== Color color =====

  * control key sample -> give a average value

====== Special nodes ====== 
===== Quick Paint node =====

  * Tools
    * clone tool
    * control key to resize brush
    * shift to move brush

===== Roto Shape =====

  * use with switch matte node
  * Switch Matte (input, Roto)

===== Tracker [can be as many as you like] =====

  * gather data, 
    * it only gather the data
    * to use the data, load the track data into other node

===== Stabilizer [max 4 points] =====

  * gather data, apply data to itself
    * Limit Processing {speed up track hi-res}
    * reference frame: start frame / every frame
    * %%------------%%
    * Tips: target should just x,y axis move
    * if the data applies to Itself, choose Stabilize
    * if the data applies to others, choose Match
    * %%------------%%
    * tools
      * offset search region : use it when original region out of screen

===== MatchMove [max 4 points] =====

  * gather data, apply data 
    * it has built-in fore-bg composition function
    * same as stabilizer's Match
