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.
