  23. # * Support --width and --height, resolving the other part from input
  24. # or forced aspect ratio.
  25. # * Drop $melt_recent flag when melt 0.9.2 is stable.
  26. # * Check and fail if all needed tools are not available.
  27. # * Test if beneficial to apply real_time=-2.
  28. # * Normalize each infile separately when xml fed as infile keeps sync.
  29. # Maybe as workaround re-feed audio separately from xml, as done at
  30. # <http://bernaerts.dyndns.org/linux/74-ubuntu/214-ubuntu-stabilize-video-melt>.
  31. # * Resolve flash player to use.

  38. Usage: $PRG [OPTION...] [--] [ARG=VALUE...] INPUTFILE... [ARG=VALUE...]
  39. Encode video file in multiple web-optimized formats, and provide sample
  40. html favoring open formats with optional non-JavaScript Flash fallback.
  41. --video Video style:
  42. ref-bpp
  43. talkinghead 0.1
  44. action 0.15
  45. (default: none)
  46. -p, --profile Video frame size and optional rate, delimited by @
  47. except "p" labels: e.g. 848x480@25 480p25 wvga@25
  48. -s, --size Set video frame size:
  49. [modulus 16]
  50. 320x240 qvga
  51. 640x480 vga 480p 848x480 wvga
  52. 576p 1024x576 wsvga
  53. 1024x768 xga hd 720p 1280x720 wxga
  54. [modulus 8]
  55. 240p 424x240 wqvga
  56. 480x360 hvga nhd 360p 640x360
  57. 800x600 svga
  58. (default: use input size)
  59. -a, --aspect Display Aspect Ratio in melt format: e.g. @16/9
  60. (default: no aspect hinting)
  61. -r, --rate Video framerate: e.g. 25 1001/30000
  62. (default: use input framerate)
  63. --refbpp Bitrate reference: Bits-per-pixel for 360p30 H.264
  64. (default: 0.12)
  65. --formats Containers and codecs to use, comma-separated:
  66. [container] [video codec] [audio codec]
  67. theora ogg Ogg Theora Vorbis
  68. vp8 webm WebM VP8 Vorbis
  69. vp9 WebM VP9 Opus
  70. h264 mp4 MPEG-4 H.264 AAC
  71. (default: webm,vp9,mp4)
  72. --audio Audio style:
  73. [channels] [limit] [Vorbis] [Opus] [AAC]
  74. music max 2 64k 64k audio 96k
  75. hqspeech 1 48k 32k voip 64k
  76. speech 1 X 48k 32k voip 64k
  77. silence 0
  78. (default: none - use channel count of first input)
  79. --audioprefilter Add audio filter before loudness
  80. --loudness Add EBU R128 loudness filter
  81. --loudness-data Add loudness filter, with precomputed results
  82. (default: none - compute results on-the-fly)
  83. --filter Add filter
  84. --stem Stem of output filenames, optionally with path
  85. (default: basename of first input)
  86. -t, --title Title used in html fallback graphics
  87. (default: stem)
  88. --sample Create only a 150 frames long sample
  89. --sample-start Create sample, starting at a specific frame
  90. (default: start at first frame)
  91. --sample-length Create sample of specified length, in frames
  92. (default: 150 frames i.e. approx. 5s)
  93. --compression Optimize for quality or speed: normal dirty hq
  94. (default: normal)
  95. -h, --help This help text
  96. Examples:
  97. $PRG -s qvga -t "Funny guy" intro.dv myvideo.dv
  98. $PRG -p 480p15 --filter "grain noise=20" myvideo.dv
  99. Recommendations for best results:
  100. * Use square pixels, modulus 16, max. 480 width (qvga vga 480p 720p).
  101. * Try lower --ref-bpp while visually acceptable, or raise to max. 0.2.
  102. * Expand and compress noisy speech with ladspa.1075 and ladspa.1916.
