Page 5: Ltc Input Mode
3. LTC input mode LTC is longitudinal timecode according SMPTE 12M, there are 80 bits containing time, userdata and a syncword. The unit detects the incoming LTC frame format automatically. The FPS LEDs 24, 25, 30 and DF indicate the detected format. 24 FPS timecode is used for movie productions. -
Page 6: Mtc And Usb Input Modes
Digital Audio Workstations as well as lighting and show control software use MTC midi timecode for synchronisation. mif 4 reads MTC to regenerate synchronised, stable LTC and MTC timecode. MTC timecode can be quite unstable and jittery caused by the latency of computer operating systems. -
Page 7: Gen Generator Mode
In MTC or USB input modes the LOCKED threshold is < 5ms, in LTC mode < 100µS. If the incoming midi timecode is jumping or drifting away so that mif 4 is unable to follow the source it will display ERROR 01 in MTC mode or ERROR 02 in USB mode. - Page 8 Example: DAW software sends MMC comands to control the mif 4 timecode generator genlocked to video syncs and then slaves itself to the returned MTC midi timecode generated from the mif 4 to achieve video genlocked playback start (locked to a virtual machine).
