EffectFireworks1 AviSynth Plugin

# EffectFireworks1

EffectFireWorks1 generates multi colored light beams in parabolic trajectories from given x and y coordinates.The height of initial rise over the initial x and y coordinates of origin of the parabolas, end x y coordinates, percentage zoom and the floor y value below which the parabolas are not seen can be specified. (In EffectFlowerPot continuity from frame to frame is maintained, while here it is not.). Zoom if more than 100 creates impression of approaching or if less than 100, receding from the fireworks initial position. RGB32, RGB24 YUY2 and YV12 only are supported at this time.

Details of parameters
Description | Name | Type | Limits | Default
clip |  | clip |  | none
Effect start frame number | sf | Integer | within clip | first frame
Effect end frame number | ef | Integer | within clip | last frame
initial x coordinate of source | initx | integer | to ensure visibilty of fireworks | mid frame width
Initial y coordinate of source | inity | integer | ensure visibility | frame height
Maximum rise of fire | rise | integer | reasonable value | frame height
Floor Y coordinate below which embers will not fall | yfloor | integer | always more than y - rise | inity
end x coordinate of source | endx | integer | to ensure visibilty of fireworks | initx
end y coordinate of source | endy | integer | ensure visibility | inity
zoom %age at end. (initial is 100) | zoom | integer | 10 to 400 | 100

#Usage examples:-

    EffectFireworks1(last,51,190, 0,300,300,400,400,200,50)
    EffectFireworks1(last,51,190,300,yfloor=300)
    EffectFireworks1(last,51,190,100,200, rise=80, zoom=300)
    EffectFireworks1(last,51,190)
    EffectFireworks1(last,2,240, initx=80,endx=400, inity=580, endy=30)
