Audio Details

The camera is equipped with two integrated microphones suitable for scratch-track audio, and it is equipped with one 3.5 mm stereo microphone input.

You can link the gain for the two channels together. This allows you to adjust the two internal (or external) channels together as one.

You can record audio from the internal microphones, from the external audio connector (2-channel recording), or from internal and external sources combined as 24-bit 48 kHz uncompressed audio tracks.

For external audio, you can only use a microphone level signal (not line level) and adjust it by using the appropriate camera gain-settings (-52.5 dB to 36.0 dB). The default camera gain setting is 0 dB.

The camera's audio data is synchronized with video and timecode, and it is embedded in the R3D file. You can export the audio data as separate audio files by using REDCINE-X PRO, if needed. The camera also embeds the audio in the SDI output.

You can monitor the audio during recording and playback by using the equipped 3.5 mm stereo headphone port.

Varispeed Audio

Firmware versions 1.5 and higher support recording audio when the camera's Recording Frame Rate is set to a higher speed than the Project Time Base setting (Varispeed mode).

NOTE: The camera records the audio as a separate WAV file and stores it in the clip's RDC folder on the media drive.

Timecode Details

Timecode provides a mechanism to reference frames from the camera's recorded clips to external devices such as, other cameras or audio recorders. Some devices can also gather additional data such as, lens metadata, or camera orientation, which Timecode can later use for merging the data back together in post-processing.

The camera provides two separate Timecode formats:

  • Time Of Day (TOD) - The camera records the time of day as the Timecode for each clip
  • Edgecode - The camera records elapsed time as the Timecode for each clip. The time is reset to 01:00:00 when a new media card is inserted in the camera. All of the clips on the media will have a continuous Timecode track. However, each new media card will default to a Timecode track starting at 01:00:00. You can change the Edgecode to begin at any desired time by using the Media Format menu (refer to Edgecode).

The camera synchronizes (jams) the TOD Timecode to an external Timecode generator (when one is connected to the Extension Port) or it jams the Timecode to its internal real-time clock.

The camera stores TOD and Edge Timecode in the R3D file. You can select which one you want to display on the LCD Touchscreen.
