To record N-Log footage, connect the camera to a digital recorder that supports 10-bit video. Use a Type C HDMI cable (available from third-party suppliers) and be sure the camera is off before connecting or disconnecting the cable.
To film N-Log footage:
1 Select 10 bit for Output data depth.
N-Log footage can only be recorded at a bit depth of 10 bits. In the setup menu, select 10 bit for HDMI > Advanced > Output data depth.
2 Enable N-Log recording.
Return to HDMI > Advanced in the setup menu and select On (cannot record to card) for N-Log setting.
3 Configure the recorder for HDMI input.
For details, see the documentation supplied with the device.
4 Start filming.
If On is selected for HDMI > Advanced > External recording control in the camera setup menu and the recorder supports the Atomos Open Protocol, you can start and stop recording using the camera movie-record button (see this section); otherwise, you will need to enable recording on the external device. Note that although N-Log footage is recorded only to the external device, not to the camera memory card, contrast can be enhanced for display on the camera during recording (see this section).
When the camera standby timer expires, the monitor will turn off and HDMI output will end. We recommend that you choose No limit or a time longer than the anticipated recording time for Custom Setting c3 (Power off delay) > Standby timer.
If On is selected for HDMI > Advanced > External recording control in the camera setup menu and the recorder supports the Atomos Open Protocol, you can start and stop recording using the camera movie-record button(for information on whether your recorder supports the Atomos Open Protocol, contact the manufacturer). The camera displays in movie live view and during movie recording. During recording, check the recorder and recorder display to ensure that footage is being saved to the device.
Although it increases the range of tones recorded, N-Log reduces the contrast between colors. If desired, the display of colors in the camera monitor can be simplified to enhance contrast for ease of viewing by selecting On for HDMI > Advanced > View assist in the camera setup menu.
If your recorder features a waveform display, you can film an 18% gray color chart and adjust exposure for a video signal level (IRE) of 35%, equivalent to a 10-bit code value of around 372.
