Short Documentation for the wf_scripts_1.lha
1. Load the file wf:sessions/TwirlAway.session inside the converter. The
process-file is loaded automaticly.
Here is the way the first example-script was created:
As Input there is black frames selected, beacause we load the pictures
inside the processor. We choose 30 frames for the input. As output we use
yafa-animation. As options we use Chunky frames (for better compression),
XPK-compression and timecodes.
We turn on the processor and the preview.
Now we go inside the processor.
(Turn folding to disabled to see the entries)
First of all we load the two images we want to fade.
`LOADIMAGE (out=TEMP1, seq='wf:Trash/face1HALVE', loop=1, shift=0)`
Output to buffer Temp1. This buffer will NOT be deleted while creating the
animation. So we tell the processor that this effect will only be executed
at the first frame of the animation.
`LOADIMAGE (out=TEMP2, seq='wf:Trash/face2HALVE', loop=1, shift=0)`
Output to buffer Temp2. This buffer will NOT be deleted while creating the
animation. So we tell the processor that this effect will only be executed
at the first frame of the animation.
Now we add a twirl-effect.
`TWIRL (in=TEMP1, out=TEMP3, centreX=80, centreY=64, fallOff=out, ...`
The picture inside the buffer 1 will be twirled and saved into buffer 3.
To get the centre of the picture we go inside the single-picture-process
and choose as input the picture wf:trash/face1HALVE and press Apply
Dimensions. As amount we will choose later on a variable called
`twirlamount`.
The background picture inside buffer 2 will be shifted and saved into
buffer 4. The variables will be created lateron. With the shift value we
select the amount the picture will be shifted into one direction. The
jitter-amount as the maximum shifting in random directions for every line.
This effect is used after the shifting.
`SHIFTLINES (in=TEMP2, out=TEMP4, shift=shift, jitter=normal, ...`
Now we compose the two pictures. We use buffer 4 as background and buffer 3
as foreground.
As variables we use:
Mix: The X-Value is the frame-Number, The Y-Value is the value at the
current frame. We start with 100 and end with 0. 100 means that you can`t
look through the foreground. 0 means that you dont see the foreground, only
the background...
Shift: This is the shift amount for SHIFTLINES effect. We start with a high
Value and end with 0. That means that the picture comes from the right side
and end with an offset of 0 pixels (means at the left side of the screen)
Jitter: This is the maximum amount for the jitter-shifting.
Jitterprob: This is the probability for the jitter-effect.
Twirlamount: This is the amount for the twirl-effect of the foreground
picture.
Aftre the creation of the variables/envelopes we select them inside the
effects.
Now we can start the converter.
Take a look at the other two scripts, too.
The wf_cube_fade.lha may only be executed if you have the Powerplug!
registration, as twmp3d buffers are used!
They will be loaded without Powerplugs!, too but the results does not look
like it should (see example animation on aminet.)
