NAME

       pfsretime - Retime an animation stream from one frame-rate to another

SYNOPSIS

       pfsretime [--in-fps <fps> | --out-fps <fps>] [--speedup <factor>]

DESCRIPTION

       Changes  the  frame-rate  of  the animation stream from the input-frame rate to the output
       frame-rate. Currently this is done by skipping or replicating frames. The command  can  be
       useful for creating time-lapse animations with temporal tone-mapping operators.

OPTIONS

       --in-fps <fps>, -i <fps>
              The  frame-rate  of  the  input  animation  stream in frames per second. Fractional
              numbers are supported. By default, the FPS tag in the stream is used.  If  the  tag
              cannot be found, 30 frames per second is assumed.

       --out-fps <fps>, -o <fps>
              The  frame-rate  of  the  output  animation stream in frames per second. Fractional
              numbers are supported. The default value is 30 frames per second.

       --speedup <factor>, -s <factor>
              How much faster (factor > 1) or slower (factor < 1) the output animation should run
              as compared with the input animation. The output frame-rate is kept the same as the
              input frame-rate.

EXAMPLES

       pfsin  frame%04d.hdr  |  pfsretime  -v  -i  1  -o   30   |   pfstmo_mantiuk08   |   pfsout
       res/frame%04d.jpg

              Read the sequence of animation frames at 1 frame per second and output the sequence
              at 30 frames per second. This will replicate each input frame 30 times. The  frames
              are then tone-mapped and stored in the res folder.
