MakeMPEG 1.01
-------------
This program is Public Domain, and is provided 'as is'. The authors cannot
accept any liability for any damage or loss of any kind as a result of the
use of this program.
You are allowed to copy, distribute and use this program for any
non-commercial purposes, as long as this file is included unaltered.
MakeMPEG is a frontend for version 1.01 or later of our MPEG encoder.
Install
-------
The program should be installed together with the other MPEG tools in a
non-write-protected directory.
In use
------
When run, the program installs an icon on the iconbar. Click on this to
open the encoder options window.
This allows you to specify:
- MPEG-1/MPEG-2.
- Playback bitrate or compression ratio (in %).
- Number of frames in a GOP.
- Film title.
The encoding process can run multitasking if you want.
Frames
------
The encoder takes either an ARMovie or a nested directory-structure holding
PPM files as input. The ARMovie can be in any format and will be decompressed
and saved as PPM files in a nested directory.
If you want to use PPM files as input, these should be numbered from 0 and
up and they should be stored in a nested directory structure, like this:
ADFS::IDE4.$.MPEG.Frames.<nn0).<nn1>.<nn2>
<nn0> is <frame number> DIV 4096.
<nn1> is (<frame number> DIV 64) MOD 64.
<nn2> is <frame number> MOD 64.
So frame number 93 is stored as ADFS::IDE4.MPEG.Frames.0.1.29.
To specify the frames directory (ADFS::IDE4.MPEG.Frames in the example above)
you drag the directory to the icon at the top of the encoder options window.
To specify the ARMovie, drag it to the icon at the top of the encoder
options window.
Output
------
The MPEG film will be stored in the frames directory as 'MPEGfile',
If you're using an ARMovie as input, the MPEG film will be stored in the
same directory as the ARMovie, and will be called 'MPEGfile'. The PPM frames
will be stored in a temporary directory inside either !Scrap, !ARWork or
!MakeMPEG.
Encoding is VERY slow - typically 1000 pixels/second on a Risc PC 600.
