 +==== Progressive mode
 +
 +so we don't need to deinterlace manually using 1080 with HD-SDI
 +
 +{{:hardware:ag-ac160a_operatinginstructions_advanced.pdf|Camera Manual Part 2}}, Page 23:
 +
 +You can shoot in progressive mode when you select 25P for 1080 mode in AVCHD mode or 25P for 576 mode in DV mode in the //REC FORMAT// item on the setup menu //RECORDING SETUP// screen. [...]
 +
 +**25P mode:**
 +Shoots 25 frames/second in the progressive mode.
 +For output and recording of video signal, the 25 frames/second image is converted to 50-field-per-second interlace signal [for SDI output]. This mode gives high quality video.

 +
 + Limiter
 +
 +The limiter is a compressor with a threshold off 0db or a little below 0 an 0ms attack and 1:∞ compression.
 +The limiter is disabled when the the pegel switch is set to "AUTO"
 +
 +
 +==== Power Supply ====
 +
 +The camera can be powered by DC using a dummy battery-pack.
 +According to the data sheet, it wants to have 7.3 V but since the Li-Ion battery will output 8.4 V when fully charged, using a 7.5 V off-the-shelf power supply is fine.
 +
 +The battery dummy does not contain any (active) components besides a ferrite core.
 +
 +A Mean Well GST18A07 has enough power, but GST25A07 is also fine if easier to obtain.
 +Just solder the cable of the dummy battery to the DC output of the power supply.
