- 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.
