You could use the lerp command.  which you can dissolve between 2
parameters.
check out the example below


set cut_paste_input [stack 0]
version 9.0 v8
BackdropNode {
 inputs 0
 name BackdropNode1
 tile_color 0xbc632cff
 label "blending between \n2 cameras"
 note_font_size 42
 selected true
 xpos -480
 ypos -144
 bdwidth 378
 bdheight 290
}
push $cut_paste_input
Camera2 {
 translate {1.68443 0 0}
 rotate {0 13 0}
 name CameraB
 selected true
 xpos -284
 ypos -13
}
Camera2 {
 inputs 0
 translate {-1.208439112 0 1.349363685}
 rotate {0 15 0}
 name CameraA
 selected true
 xpos -439
 ypos 1
}
Camera2 {
 inputs 0
 translate {{lerp(CameraA.translate,CameraB.translate,slider)}
{lerp(CameraA.translate,CameraB.translate,slider)}
{lerp(CameraA.translate,CameraB.translate,slider)}}
 rotate {{lerp(CameraA.rotate,CameraB.rotate,slider)}
{lerp(CameraA.rotate,CameraB.rotate,slider)}
{lerp(CameraA.rotate,CameraB.rotate,slider)}}
 scaling {{lerp(CameraA.scaling,CameraB.scaling,slider)}
{lerp(CameraA.scaling,CameraB.scaling,slider)}
{lerp(CameraA.scaling,CameraB.scaling,slider)}}
 name Camera_dissolved
 selected true
 xpos -360
 ypos 76
 addUserKnob {20 User}

Re: [Nuke-users] Mixing two cameras animation using local matrix

2016-09-20 Thread Michael Habenicht

If you have a knob called mix which contains the amount of one of the cameras 
the expression should be this: 
Camera4.world_matrix*mix+Camera5.world_matrix*(1-mix)
With this you should be able to mix between the two cmaera paths.

Best regards,
Michael
