pmblur2 - apply motion blur to a frame from an animation
pmblur2 f0,f1/n HDRspec ZBFspec MVOspec
Pmblur2 Computes a square-shutter blur from frame position f0 to frame position f1 using the given picture, depth buffer, and motion vector offset files produced by ranimove(1). These arguments should be set similarly to the BASENAME, ZNAME, and MNAME variables in the ranimove input file, but should include the suffixes as well.
The starting and ending frame number are usually given as floating-point values. For example, the range "10.75,11.25" would simulate a 180-degree shutter around frame 11. An optional time slice count may be given to override the one that is computed by default. The range "5,15/30" would blur all the frames from 5 to 15 continuously using 30 time slices. The blurred image is always sent to stdout.
To blur and downsample frame 95 with a 360-degree shutter:
