Source number

The source number of a non-active file can be changed to any other source number. This makes it
possible to create a file for future source numbers.

Clamp position

Clamping determines the black level of the signal. The clamp pulse can be related to the leading or
the trailing edge of the sync pulse. Use the ENTER key to toggle between [leading] and [trailing].

Clamp delay

The time between the leading edge of the clamp pulse and the locked edge of the sync pulse. Can be
any value between 0 and 255. Change the value by pushing the cursor key ↑ or ↓.

Field polarity

The field polarity function is used for interlaced images. Both rasters of the image could be shifted in a
wrong way (double lines are visible in the image). This can be corrected by forcing the field polarity to
[neg] or [pos]. Use the ENTER key to toggle between [pos] and [neg].

Field select

Default [both]

The field select is only used for interlaced images. One frame of an interlaced image contains two
fields, an even and an odd field. The choice exists to project [both] fields on the screen or only the
[even] or [odd] field. This can be useful for 3D projection. Use the ENTER key to toggle between
[both], [even] and [odd].
