The record menu allows you to apply pulldown removal if recording from a source that applies pulldown to the output signal. Tap Pulldown Format to cycle between the options.
For 3:2 Pulldown removal, movement in the frame may be required to accurately lock signal, simply wave your hand in front of the camera to achieve lock.
What is Pulldown?
Many professional and consumer cameras available today do not send true 1080p24, 1080p23.98, 1080p25, 1080p29.97 or 1080p30 signals to their HDMI outputs. Instead they send 1080i59.94 in NTSC regions (e.g. USA, Japan), and 1080i50 in PAL regions (e.g. 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.
SHOGUN CONNECT Receives
You will of course want the SHOGUN CONNECT 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 CONNECT to detect when pulldown has been applied to the video, so you will have to set the correct mode of removal on the SHOGUN CONNECT to match the setup of your camera.
With some cameras, the SHOGUN CONNECT can detect and remove the pulldown automatically, in which case the mode you expect (e.g. 1080p23.98) will display on the SHOGUN CONNECT 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.
ATOMOS is adding auto-detection support for more cameras, please check for firmware updates regularly at www.atomos.com
1080p23.98 or 1080p24
If you have set 1080p23.98 or 1080p24 in your camera and your SHOGUN CONNECT 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 CONNECT needs to analyze 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 CONNECT 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 difficult, it is 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 CONNECT.
Some cameras use a variant of pulldown removal, for example Panasonic Advanced pulldown. The SHOGUN CONNECT 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.
Pulldown is only applicable to interlaced HD signals, not 4K
