NAME
ppm2raw − Convert a PPM pipe to a Raw DV stream
SYNOPSIS
ppm2raw [ options ]
DESCRIPTION
ppm2raw converts a PPM to a Raw DV stream.
OPTIONS
|
−n |
NTSC output required. | ||
|
−a |
Maintain aspect ratio when scaling images. | ||
|
−s |
Scale images to the full frame size, regardless of aspect ratio | ||
|
−w |
Wide screen output (default: off). |
−p number
Number of encoder passes (default is 3).
|
−q qno |
Encoder qno. |
−b colour
Use the colour triple for backgrounds - default is 000000. Format must be a hex string representing red, green, blue. For example, ffffff would be white.
|
−A wav |
Use the wav to dub the output. The wav file must contain stereo, 16 bit samples at a frequency of 32khz, 44.1khz or 48khz. | ||
|
−2 |
Two pass encoding (default: off). |
HELP OPTIONS
|
−−help |
Show help message. |
EXAMPLES
ppm2raw needs a PPM input provided on stdin. Fortunately, many tools generate PPM on stdout.
For example, to re-encode any ffmpeg compatible file or stream format to a PAL Raw DV stream which rescales the images according to the aspect ratio of the input using the following command:
ffmpeg -i
’some-file’ -f ppmpipe - |
ppm2raw -a > file.dv
For NTSC, you would add -n to the ppm2raw command.
