Doug- Define Broadcast quality.
The signal quality from the Magni is certainly acceptable for broadcast
purposes. In fact, in a pinch, I've used the Magni to produce house sync for on
line production of a TV commercial.
Although 8 bit color and non frame accuracy animation has its technical
problems for broadcast, this has nothing to do with the Magni signal output.
What specific test methods have you performed to evaluate the signal purity
from the Magni and what were those results? I'm sure that Magni engineers
would be most curious about your conclusions. I had reported a slight chroma
burst rise distortion in one of their earlier cards and they promptly RMA
repaired it.
Remember the GIGO rule "Garbage In -Garbage Out" If you feed a FLC file to the
Magni its output will not meet RS-170(A) standards. However, feed it a still
640X480 8 bit signal and the video output will pass for broadcast at most TV
stations. I've never had a complaint with my stuff.
My definition of Broadcast Quality is minimum to be FCC legal. But then my
discipline is broadcast engineering not advertising and marketing where buzz
words are used to impress others.
I know you were specifically refering to animation, and with that I agree the
Magni can not output an FCC legal video signal but you made it sound like the
Magni has too low of a signal quality to be used in broadcast which is just not
true!
