Kaleidoscope to Krystal Effect Translator
■ If you want to use an external key as mask and not a key, you will need
to route the key signal to the external mask and modify keyframes.
This application works well when Krystal is integrated with our digital
production switchers.
■
Kaleidoscope user crops convert to box crops in Krystal when wipes
are not used to mask. If you want both, you will need to turn on the
mask mix, check the box mask values and adjust the mix.
■
Krystal has two separate pattern generators: pattern crop and pattern
mask. The crops and masks are affected whenever a Kaleidoscope
effect uses wipes for masking instead of keying.
■ The following rules are used when converting wipe crops:
a. If masking is used, Kaleidoscope wipe crops will convert to pattern
masks on Krystal.
b. If masking is not used, Kaleidoscope wipe crops will convert to
pattern crops on Krystal.
■ After a conversion that used the wipe system, both pattern crops and
pattern masks will share values keyframe for keyframe. Mask crop will
be turned on and pattern crop will be turned off.
Keying
■
Krystal has two separate key generators: keyer and external mask. The
keyer and external masks are affected whenever a Kaleidoscope effect
uses keying for masking instead of keying.
■
The following rules are used when converting keyers:
a. If masking is used, Kaleidoscope keys will convert to external
masks on Krystal.
b. If masking is not used, Kaleidoscope keys will convert to keyer on
Krystal.
■
After a conversion that used the keyer, both keyer and external masks
will share values keyframe for keyframe. Keyer will be turned on and
external mask will be turned off.
Pseudo Color
■
All pseudo colors effects except contrast are converted completely. If a
Kaleidoscope effect uses contrast, COLOR COR will be enabled on
Krystal and its values set at unity. You can then modify the keyframes
to the desired settings.
