1. comparing AE & NUKE

• project setting
  • ae ; control n ; for compositing setting
  • nuke; s ; project setting
• bringing footage
  • ae ; file > import > file ; ctrl i ; opening up sequence
  • nuke ;
    • r ; automatically changed into sequence / unclick and also bring each frame
      • from read ; you can set frame range / frame / and all others.
        • which is a advantage compared to ae
• color
  • nuke ; defaulted to float ; which is a “linear color space”
  • ae ; 8 bits ; 8bpc ;
    
    • at the project setting ; color settings ; depth : 8bits per channel
      • we have to change this to 32 bits per channel to match

• timeline
  • ae ; default to tc which is opposite to nuke
  • nuke ;
    • can move frame by frame
    • tc ; time code
    • tf ; global ; default mode
• import ; nuke is way flexible
  • ae ; a bit tricky
    • if you drag multiple you only get one sequence
    • but if you check multiple sequences
      • you will bring all frame.
    • use layer to make front ; back
  • nuke ; if you drag bunch of sequences you can just put 1,2,3 - to see.
    • main pass has alpha channel
    • that’s the main render from redshift now
    • use merge node (over) a ; foreground / b; background
• color
  • nuke ; grade /
  • grade ; contrast / black point / white point / multiply
  +t ; the explanation was about nuke is easier to make different version and compare.
• light
  • ae ; use blending mode to add light ; normal to add
  • nuke ;
    • merge more layers
    • + merge three different light
      • but switch merge blending mode ; over to “plus”
• ae / nuke image difference
  • reason ;
    • calculation of linear colour space in nuke the mathematical calculation is slightly different from ae
    • fix ; ae ;
      • project setting ; color settings ;check ; blend colors using 1.0 gamma
      • 
      • blending will be matched to the nuke
      • if you don’t this you cannot see the dynamic range.
      • in 8 bit(full clamped) it lost
      • in this way 8 bit to 16 or 42 (alter dynamic range) like in nuke
• playback
  • ae was slower than nuke bc it’s not optimized to float
  • that’s why nuke is used in production so much more in visual effects for art or visual effect.
• comp
  • ae ; comp ; render cue ; ok to render
  • nuke ; w ; write node ; double click ; name ; pick mov options ; render
