Video image area options

The image area for videos can be selected using [Image area] > [Choose image area] in the video recording menu. The crop used for filming video varies with the option selected. Regardless of the option selected, the aspect ratio is 16 : 9.

• Select [FX] to shoot videos in what is referred to as “FX-based video format”, [DX] to shoot in “DX-based video format”.
• The image area changes according to [Frame size/frame rate] settings when [N-RAW 12-bit (NEV)], [R3D NE 12-bit (R3D)], or [ProRes RAW HQ 12-bit (MOV)] is selected for [Video file type] in the video recording menu. The option selected for [Image area] > [Choose image area] in the video recording menu does not apply.
• When 5376 × 3024 is selected for frame size, image area is fixed at [FX]. In such a case, the frame size changes to 3840 × 2160 if a DX lens is attached.
• When [3840×2160; 119.88p] or [3840×2160; 100p] is selected for [Frame size/frame rate], image area is fixed at [DX].
• When [1920×1080; 239.76p] or [1920×1080; 200p] is selected for [Frame size/frame rate], the angle of view is equivalent to approximately 95% of the focal length of the FX format. The frame rate changes to 119.88p or 100p when a DX lens is attached.
• The option currently selected is shown by an icon in the display. If [ON] is chosen for [Image area] > [DX crop alert] in the video recording menu, an image-area icon will flash in the shooting display when the DX crop is selected.
