Transition Commands
Fade to Black / Fade from Black 0
These commands cause the total output from the selected keyer layer to be
faded to or from black. Repeated commands of the same sort have no effect.
If the command is not finished when a reverse instruction is received, the
fade will reverse direction and continue at the same rate. The transition
duration of the fade to/from black can be set using the B command or by
using the optional third parameter for Imagestore 300[+], Imagestore HD-
TV, Imagestore 750, LGK-3901 and DSK-3901. The value provided sets the
number of fields to complete the action. This value may range from 0 to 999
decimal, but is encoded in the command as hexadecimal.
CMD Param_1 Param_2 Param_3 (optional)
0 Layer No. 0=To black, 1=From black
2=Fade to/from black
Rate in fields
(1-999)
Example:
void FadeToBlack(int Layer, bool Black)
{
remote_send("0%x %d", Layer, Black ? 0:1);
}
Fade Keyer Up / Fade Keyer Down 1
These commands cause the keyer layer to be faded up or down. When the
keyer is faded down, the background is passed unchanged. Repeated
commands of the same sort have no effect. If the command is not finished
when a reverse instruction is received, the fade will reverse direction and
continue at the same rate. The transition duration of the fade keyer up/down
can be set using the B command or by using the optional third parameter for
Imagestore 300[+], Imagestore HD-TV, Imagestore 750, LGK-3901 and
DSK-3901. The value provided sets the number of fields to complete the
action. This value may range from 0 to 999 decimal, but is encoded in the
command as hexadecimal.
