Weave 1.0 ⌐ 1995 by Neil Taneja
Introduction:
Weave combines 2 pictures (IFF format) for field rendering.
Field rendering gives you 60 fields per second instead of 30 frames.
This is done by taking all the odd lines from one file and all the
even lines from another and combining them into an output frame.
Why would you want field rendering when it cuts your resolution in
half? Because most of the time frame rate is better than resolution.
Quick panning across something in an anim would look jumpy at 30
frames per second but smooth when field rendered.
Weave is best used with some kind of hardware anim player like PAR
or VLAB. Field rendering needs constant playback which standard anim
players don't provide.
Installation:
Place Weave in your path somewhere. (Like C: or BIN:)
Place Weave.rexx with your other arexx programs. (Like REXX:)
Usage:
Weave itself just takes 2 input frames and combines them into an
output picture...
Weave OddFile EvenFile OutFile
Input pictures must be same size and depth. Weave supports any size
and any depth up to 24 bitplanes.
To proccess multiple frames use Weave.rexx.
rx Weave.rexx InBaseName [OutBaseName] [StartFrame]
The base name looks for the format Frame001 (name with 3 digits after).
OutBaseName and StartFrame are optional. Without OutBaseName output
frames will have an '╖' (Alt-8) added to the end of the output file
name. StartFrame must be even.
Weave.rexx will check every 10 seconds for an even frame then call
Weave after it finds one. After Weave finishes Weave.rexx will delete
the 2 converted frames and start waiting for the next even frame.
**IMPORTANT**
After all your frames are processed you need to tell Weave.rexx that
there are no more frames so hit Control-C. Weave.rexx will stop next
time it checks for a frame (less than 10 seconds).
Examples:
To convert all the frames in (or coming into) the current directory
assuming the names are in the foo001 format.
rx Weave.rexx foo
After all the frames have been converted hit Control-C.
Your render program outputs test001, test0002... to ram:. You want
output frames from Weave to go to your PAR.
You simply type...
rx Weave.rexx ram:test ddr:project/test
After all the frames have been converted hit Control-C.
If you stopped the render and want to start it again at frame 200...
rx Weave.rexx ram:test ddr:project/test 200
After all the frames have been converted hit Control-C.
