Under the MODE option, you can set the timecode mode, and you can choose “OFF”, “AUTO”, “ONCE”, “FREE” and “REC”modes. OFF: timecode is off; AUTO: the default setting, which automatically recognizes the wired/wireless timecode for synchronization; ONCE: automatically synchronize the timecode information once and then lock it. After locking, the timecode will not be automatically synchronized again, and the lock will be released by switching modes; FREE: the time information set by the current device is timecode, which does not support restart timecode and does not accept external timecode signals. REC: the timecode follows the ‘start/stop’ of the recording function. In this mode, when recording is started, the timecode automatically starts running; when recording is stopped, the timecode automatically stops running.
Timecode frame rate setting The frame rate of timecode recording, you can set the frame rate as 23.98,24,25,29.97,29.97DF,30 as required. DF stands for dropped frame. The default frame rate of the system is 25, so it is suggested to set an appropriate frame rate in advance.
