Atomos SHOGUN 7 User Manual

Atomos Shogun 7 – User Manual Edition 1: November 2019 43
1080p23.98 or 1080p24
If you have set 1080p23.98 or 1080p24 in your camera and your Shogun
7 displays 1080i59.94 or 1080i60, then you can easily remove the
pulldown by following these steps:
• Select the Input Menu from the top Left and toggle the blue arrow
underneath Record repeatedly until you see 1080p23.98 (or 1080p24)
displayed. You may not get a green tick in this column immediately.
• Your Shogun 7 needs to analyse the video for about 1 second, in
order to detect the pulldown sequence and remove it.
• If it is not automatically detected after 1 second, wave your hand from
side to side in front of the lens, or wave the camera from side to side
for a few seconds. The Shogun 7 will detect the pulldown cadence
in the movement, and you will see a green tick along with the video
displayed on the screen.
3:2 pulldown detection is difcult, if not impossible to detect on
completely still video. This is why you should wave your hand in front
of the lens.
If you lose the input detection – for example you unplug the HDMI
cable or go to Playback mode, you will need to wave your hand or the
camera again, when the signal is restored to the Shogun 7.
Some cameras use a variant of pulldown removal, for example
Panasonic Advanced pulldown. The Shogun 7 does NOT support this
format, and it will not be detected.
Standard Panasonic pulldown is supported, ensure in the Panasonic
camera settings that pulldown is not set to Advanced.
1080p25, 1080p29.97 or 1080p30
For these modes, access the Record Menu tab and simply press the
Record Format options repeatedly until your 1080p desired format is
displayed. There is no need to wave your hand or the camera, as 2:2
pulldown removal does not require moving video.
What is Pulldown?
Many professional and consumer cameras available today do not send
true 1080p24, 1080p23.98, 1080p25, 1080p29.97 or 1080p30 signals
down their HDMI outputs.
Instead they send 1080i59.94 in NTSC regions (eg USA, Japan), and
1080i50 in PAL regions (eg Europe)
In order to convert the signal from the internal recording format to
1080i5994 or 1080i50, they use a process called 3:2 or 2:2 pulldown.
Pulldown is only applicable to interlaced HD signals, not 4K
Camera Setting Pulldown Shogun 7 Receives
1080p23.98 3:2 1080i59.94
1080p24 3:2 1080i60
1080p25 2:2 1080i50
1080p29.97 2:2 1080i59.94
1080p30 2:2 1080i60
You will of course want the Shogun 7 to record the actual frame rate such
as 1080p23.98, not the1080i59.94 to disk. In many cases, it is not
possible for the Shogun 7 to detect when pulldown has been applied to
the video, so you will have to set the correct mode of removal on the
Shogun 7 to match the setup of your camera.
With some cameras, the Shogun 7 can detect and remove the pulldown
automatically, in which case the mode you expect (eg 1080p23.98) will
display on the Shogun 7 and you will not have to do anything further.
If there is no input detected, then toggle the input by pressing the screen
until you see the input you wish to record.
