Sick Node Tricks - or, how to reproduce common effects using the node editor.

Node Tricks (Olive 0.2.x).md

General Tips and Tricks

• Think of clip nodes as containers!
  • You can plug in an arbitrary composite node and make them "instances" of said node

Common Node Configurations

Drop shadow (TinglesMagicWords)

A simple drop shadow effect, assuming you have a solid color and transparent clip such as text.

Picture-in-Picture

here's how a track-based PnP would work in 0.2
The Math nodes here are both set to Multiply
The Ortho nodes are just how the Transform effect works for now, you multiply it with a footage
Now that I think about it, the track layout in the timeline doesn't really matter that much, as in: that one track above another doesn't imply that the upper track will be on top of the lower track
I could just change up the merging order in the node editor

Wiping effect

To get back on topic

Here's a simple wipe effect setup in 0.2.x
"Wipe vid." is a Video Input with the wipe "mask" video (not present in the timeline)
"Wipe *" is a Math effect that puts the video inside of the "mask" video by multiplying them together
Transform is a Math effect that multiplies both the video input and the Ortho node to apply the transformation

Sick Node Tricks

Use an LFO to control the volume of a track

1. Create a low frequency sine wave audio file using something like Audacity. Make it as long as you need. This will be your lfo.wav.

2. Multiply the lfo.wav and your audio file together.
