9. Technical information
4. Exploded movie format
As described in 7. RCompress, the first stage of the Acorn compres-
sion routines generates several files in a special directory. These files
form the exploded movie.
The exploded movie directory contains these files:
Header
Contains 14 lines of text that form the Acorn Replay movie
header: You can edit the second, third and fourth lines (title,
copyright/date, and author). Do not edit any other line and
do not add extra lines.
Images
(optional)
Frames are stored as a series of sub-directories called
Images°, Images1, and so on. Each sub-directory contains
up to 74 frames.
If these files are absent, Join produces a soundtrack-only
movie.
Info
A text file used by !RCompress to record the origin of the
uncompressed movie.
Key
(optional)
Similar to Images, this contains Key frames.
Log
This lists information on the compression of each frame in
the exploded movie.
Sound/Samples/ADPCM
(multiple files – optional) The base
name is Sound1 (for 8-hit logarithmic data); Samples1 (for 16-
bit linear data), or ADPCM1 (for adpcm compressed data). (
ADPCM files may be produced by other applications – it is not
an option for Eagle movie grabs.)
!RCompress does not create these files. Instead, when it
joins the movie, it reads the soundtrack from the original,
uncompressed file.
If you add or delete soundtrack files, you may need to edit
