While making Joe's Filters, I needed
something to help me see what was happening inside the scripts. Often
values didn't seem to work right, even though everything seemed correct.
At first I added a text string line to a few filters, to show the important
values onscreen, then those grew into standalone filters which reported
all kinds of values and other information.
Unlocked versions of Joe's Debugging and Exploration Filters are included
for free with the trial and paid versions of Joe's
Filters in the hope that they will help other people make filters
with FXScript.
This allows for simple experimentation with values
in a 3x3 Convolve Matrix. One of these is included with the Quicktime
effects, but I built this one to be sure of where the values were
going. Convolution Matrixes can be used for several common digital
effects such as sharpening, finding edges and embossing.
This is another 3x3 matrix filter which simply shows
values onscreen, helping to visually relate them to their position
in the matrix. 3x3 Matrix functions are a foundation of digital imaging
and can be used for color and pixel adjustments.
This filter demonstrates the how a 3x3 filter can be
used to remap channel values. Color transformations based on 3x3 Matrixes
can be used for several common color adjustments such as saturation,
desaturation, hue rotation or colorizing an image.
I wrote this filter to check the values of the LinearRamp
constant. It shows that the description in the Final Cut Manual is
incorrect. LinearRamp contains 256 values between 0 and 1, not a ramp
of values from 0 - 255.
This is a catch-all filter which I created to see the
values of many FXScript Constants. This helped me understand quite
a lot about how FXScript works. Included values: Ratio, Duration,
Frame, Fps, Pixel Format, Aspect Ratio, RenderRes, ZoomFactor, "Corrected
Duration, Width and Height.
Changing pixel formats in YUV Aware documents was very
confusing, this filter helped me figure out which formats produced
which results and when to convert and when to reassign pixel formats.
This filter shows the effect of various conversions, assignments and
sets of conversions between RGB and YUV pixel formats.
This filter helps to understand the working of point
coordinates and how to manipulate and use point data. Shows how to
get a color from a point, interpolate the position of points and find
the angle between points.
This is the little watermark script I stuck onto my shareware
filters to add the shareware reminder to the last second of filtered
clips longer than three seconds.
