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

- -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.

- 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.
