6 pfsretime - Retime an animation stream from one frame-rate to another
7
9 pfsretime [--in-fps <fps> | --out-fps <fps>] [--speedup <factor>]
10
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
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.

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.
