Tutorial 7: Roll
Drop 3 nodes with CTRL. these are NOT 3D world Nodes, they exist only in time.
0:00 0:02 0:04 0:06 0:08
1 cubic 0-------------------------------0------------------------------0
-roll O-------0-------0-------0
-focus
-cmd
2 cubic 0--------------------------------------------------------------0
Move the first node to 0:00. 2nd node at 0:04, third Node to 0:08

select the 2nd Roll node on the timeline (the node at 0:04)
the info box tells you what you can adjust.
hit '1'.
you can adjust the value here by moving the mouse up and down.
Notice the velocity graph. there is a line running through the center. positive number will make the graph go up. Look at the info box, under "VALUE".
Positive numbers = camera rotates Counter-clockwise.
Negative number = camera rotates Clockwise
Adjust the value to number like 5.
play this.
Now adjust the third node to a value of -15.
Play this.
Pretty cool, eh!?
Now, grab that second node and give it a value of 180. (Be careful with Super high values)
The velocity graph should look like a bell curve.
hit '3'
this adjusts the velocity around the node, but NOT the value. It’s just another little way to tweak the acceleration curve.
It's a little quirky. move the mouse up and down.
The best way to understand this is to just watch what happens to the roll value on the graph.
play it back to get an idea of what it is doing. This only seems to make sense by watching the Velocity Graph.
This is one of those things that just takes practice to fully understand.
NOTE: A Focus path would NEVER need a roll value!!
TRY THIS: Put any roll value to 180. (As in 180 degrees). The camera will turn completely upside down!!
save and take a break.
