NAME

6       pfsoutyuv - Write frames to .yuv file used by many video codecs
7

SYNOPSIS

9       pfsoutyuv [--verbose] [--quiet] [--bitdepth] [--colorspace] [--downsam‐
10       ple-filter] [--chroma-format] <file> [<file>...]

DESCRIPTION

14       Use this command to write the pfsstream to an uncompressed .yuv file.
15
16       If the output color space is LDR (bt709), the input pfs  stream  should
17       be  in  the gamma corrected sRGB color space. If the output color space
18       is HDR (pq2020 or hgl2020), the input pfs stream should  be  in  linear
19       RGB color space.

OPTIONS

22       --bitdepth, -b
23              bit-depth of the integer values stored in the yuv file. a single
24              color component is stored as a byte if bit-depth is 8, or as two
25              bytes otherwise. default: 10 [bits]
26
27       --colorspace, -c
28              Currently it can be either:
29
30              pq2020  for  HDR  images with BT.2020 colorspace and PQ transfer
31              function, or
32
33              hlg2020 for HDR images with BT.2020 colorspace and HLG  transfer
34              function, or
35
36              bt709  for LDR images in BT.709 (rec.709) colorspace without any
37              transfer function.
38
39       If no option is specified, colorspace is inferred  from  the  LUMINANCE
40       tag  in  the  pfsstream:  pq2020  if LUMINANCE is ABSOLUTE or RELATIVE,
41       bt709 if LUMINANCE is DISPLAY.
42
43       --chroma-format, -f
44              The sampling format for the chroma channels. Can be one of:
45
46              444 The standard 4:4:4 format with no chroma downsampling.
47
48              420 The 4:2:0 format with both colour channels being downsampled
49              by half.
50
51              default: 420
52
53       --downsample-filter, -f
54              The  filter  weights  used  when  downsampling  to 4:2:0. Can be
55              either
56
57              f0 Weighting = [1/8, 3/4, 1/8]
58
59              f1 Weighting = [1/4, 1/2, 1/4]
60
61              default: f0
62
63       --srgb-input -s
64              Set if the  input  is  gamma  corrected,  though  this  will  be
65              inferred otherwise from the LUMINANCE tag in the pfs stream
66
67       --linear-input -l
68              As above, set if the input contains linear luminance values
69
70       --verbose, -v
71              Print extra information to stderr.
72
73       --quiet, -q
74              Disable  warning  message  about the change in handling absolute
75              values in RGBE files. See IMPORTANT NOTE below.

EXAMPLES

79        pfsin frame%04d.exr | pfsoutyuv video%s.yuv
80              Converts a sequence of frames frame0000.exr, frame0001.exr,  ...
81              to a yuv file.
