Why can't I see an orange area when setting the dead pixel position?

If the clip that you are applying DH_Reincarnation to is not set to 100% scale in the Motion tab, then this will affect the setting of the dead pixel area in the Canvas. To work around this, do the following:

1. Select the Motion tab on the clip and note the scale value.
2. Change the Scale to 100%.
3. Set the dead pixel area in DH_Reincarnation.
4. Set the Scale back to the original value.
