EffectFlashes
EffectFlashes during the first Tsmoke seconds generates smoke filled
area (in a dark sky). Thereafter a series of light (reddish) flashes occur in the smoke
filled portion. This effect resembles Aireal flashing fire works. The duration
of flashes 'tflash', maximum radius of area 'radius' and its center 'x' and 'y'
coordinates may be specified. Reasonably long dark (or black blank) clip
will show the effect properly.
RGB32, RGB24, YUY2 and YV12 only are supported at this time.
