Video performance
- When using the D7100 as a video capture mode, the camera will display audio meter overlays over the left edge of the LCD.

Advantages and disadvantages
The sensor of the D7100 uses Nikons DX format, resulting in a crop factor of 1.5x. Additionally the software enables an additional crop of 1.3x (resulting in approximately 1.95x compared to 35mm). Selecting this additional crop mode allows faster focusing in video mode and also enables interlaced video recording modes.
Compared to other Nikon Cameras the D7100's firmware has a bug still not resolved by today (February 2015) which affects photo playback over HDMI. When zooming into a photo there appear black bars on the left and the right of the screen which in fact crops the visible image and thus wastes screen space resp. not using the whole display width for HDMI photo playback (at 1080p output resolution).
