The camera can record using a progressive frame rate (shooting frame rate) that is different from the playback frame rate. Recording a clip with a shooting frame rate higher than the [Frame Rate] setting will result in a slow motion effect during playback. Conversely, a lower shooting frame rate will result in a fast motion effect. Sound is not recorded with the clip, but it can be recorded separately as a WAV file. The maximum recording time of a single clip is the equivalent of approximately 6 hours of playback time. You can record proxy clips simultaneously with slow & fast motion clips. XF-AVC proxy clips will have the same shooting and playback frame rates as the primary RAW clips.

1. To record audio, insert an SD card into the card slot where video is not being recorded.
2. Select MENU > [Recording/Media Setup] > [Recording Mode] > [Slow & Fast Motion] or [S&F Clip/Audio (WAV)].

3. Select MENU > [Recording/Media Setup] > [Slow & Fast Frame Rate] > Desired frame rate.
   • You can also choose a preset value (half, same or double the playback frame rate).
4. Press the REC button to begin recording.
   • The tally lamp changes from green (power indicator) to red.
   • [S&F STBY] changes to [S&F REC] while recording.
5. Press the REC button again to stop recording.
   • The clip is recorded on the selected card.
   • When [S&F Clip/Audio (WAV)] is selected, a WAV file will be recorded on the card where video is not being recorded.
   • The tally lamp changes from red to green (power indicator) and the onscreen display changes back to [S&F STBY].
6. Select MENU > [Recording/Media Setup] > [Recording Mode] > [Normal Recording] to turn off slow & fast motion recording

NOTES

• ​The shooting frame rate cannot be changed while recording.
• If you change the system frequency, slow & fast motion recording will be canceled and the shooting frame rate will be reset to its default value.
• About the time code when slow & fast motion recording is activated:
  • The time code mode can be set to [Regen.], or to [Preset] with [Rec Run] running mode.
  • If the time code running mode was set to [Free Run], the time code running mode will be changed automatically to [Rec Run] when slow & fast motion recording is activated.
  • When the special recording mode is turned off, the time code running mode will return to its previous setting.
  • The time code signal will not be output from any terminal.
• Recording WAV Files
  • Audio is recorded with the following settings: 48 kHz, 24 bit, 4 channels.
  • If video cannot be recorded due to a card problem, audio will also not be recorded.
  • However, video will be recorded even if audio cannot be recorded due to a card problem.
  • Audio will not be recorded if there is an existing WAV file with the same file name.
  • Audio recording will stop automatically after reaching 60 minutes (video recording will continue).
  • A maximum of 999 WAV files can be recorded.
