NAME

6       pfsretime - Retime an animation stream from one frame-rate to another
7

SYNOPSIS

9       pfsretime [--in-fps <fps> | --out-fps <fps>] [--speedup <factor>]
10

DESCRIPTION

12       Changes  the  frame-rate  of  the animation stream from the input-frame
13       rate to the output frame-rate. Currently this is done  by  skipping  or
14       replicating  frames.  The command can be useful for creating time-lapse
15       animations with temporal tone-mapping operators.
16

OPTIONS

18       --in-fps <fps>, -i <fps>
19              The frame-rate of the input animation stream in frames per  sec‐
20              ond.  Fractional  numbers are supported. By default, the FPS tag
21              in the stream is used. If the tag cannot be found, 30 frames per
22              second is assumed.
23
24       --out-fps <fps>, -o <fps>
25              The frame-rate of the output animation stream in frames per sec‐
26              ond. Fractional numbers are supported. The default value  is  30
27              frames per second.
28
29       --speedup <factor>, -s <factor>
30              How  much  faster (factor > 1) or slower (factor < 1) the output
31              animation should run as compared with the input  animation.  The
32              output frame-rate is kept the same as the input frame-rate.
33

EXAMPLES

35       pfsin  frame%04d.hdr  |  pfsretime  -v  -i 1 -o 30 | pfstmo_mantiuk08 |
36       pfsout res/frame%04d.jpg
37
38              Read the sequence of animation frames at 1 frame per second  and
39              output the sequence at 30 frames per second. This will replicate
40              each input frame 30 times. The frames are then  tone-mapped  and
41              stored in the res folder.
