Particle Emitter

This section holds all controls of the particle emitter. The particles will be emitted from a single emitter that can be moved around by using keyframes and it can emit the particles into any direction. The emitting area exists as a single point as well as a resizeable adjustable area that can cover even the whole screen. This makes it possible to emit particles from virtually everywhere at the same time.
An emitted particle receives it parameters for it's life only at the exact moment when it is emitted. The parameters of an emitted particle do not change over the life of the particle even if the emitter changes it's parameters constantly.
Emitting Rate
Here you can define the rate how many particles will be emitted. A setting of 100 will emit one particle every frame. A setting of 1 emits an average of one particle every 100 frames. The rate is randomized for settings below 100. You can change the emitting rate freely by keyframing this slider. This makes it possible to emit some particles within a certain timeframe and more or less right after it without manipulating already emitted particles.
Life Min. (frames)
Life Max. (frames)
These two sliders define the minimum and the maximum lifetime of a particle. The lifetime is calculated in frames. A lifetime of 300 will create a particle of that lives exactly 10 seconds if your sequence settings are set to NTSC with 30 frames/second.
Origin
Point (white)
Spread (range)
Origin is the place where the particles emit from. Usually the emitter is a just a point, but with Spread you can define a wider area around the emitter, where the particles emit randomly from. The area will be shown in the canvas as a white rectangle.

Direction
Spread (angle)
Direction tells the particles where they have to head. Spread spreads out the particle in an angle. If Spread is set to 0 the particles will all go into the same direction; set to 360 means that the particles head to any direction.

Speed

Randomize (Slower<>Faster)
Acceleration
Speed, as the name says, defines the speed of the particle when it leaves the emitter. If Speed is set to 0 the particles will emerge and will only gain any speed if gravitation, wind or the magnets affect it.
Randomize simply randomizes the starting speed. If this is set to 0 all particles will begin their life with exactly the same speed.
Acceleration speeds up or slows down a particle over it's life. This behavior starts with the very first frame and ends with the end of the life of the particle. If for example a particle is set to slow down, it will always behave as if it has a foot on the breaks all the time, even if it gets attracted by all the other effects (gravitation, wind, magnets). Of course the additional effects (gravitation, wind and the magnets) will still have an effect on the particle with the foot on its breaks.

Gravitation
Gravitation performs a pull downwards to the ground (lower part of the screen) to the particles.
Single Particle
This option adds the gravitation effect to the single particles as they are emitted. The gravitation will still keep it's effect for the "living" particles even when this option is turned down to 0 using keyframes.
Global
The global gravitation affects all currently existing particles. If this effect changes it's value to 0, the gravitation will stop affecting the particles and they will proceed in the direction where they are just heading to right before the global gravitation stopped.
Wind
Windspeed (left<>right)
Wind blows the particles to the left or the right. This parameter will not be added to the single particles, instead it will affect all particles simultaneously.
