22 TASCAM HD-P2 Owner's ManualContinued from the previous pageTimecode• 24.00 – This frame rate is used in both film andHDTV systems.• 25.00 – Used for PAL video.• 29.97DF – Standard frame rate for NTSC video withwall time matching the drop-frame video time.• 29.97ND – NTSC video with non-drop encodedframes.• 30.00DF – True 30 frame-per-second rate but withdrop-frame encoded LTC.• 30.00ND – 30 frames-per-second, non-drop encodedLTC.Rate Pull Up/DownNormally a synchronized audio clock is set to beprecisely 44,100 Hz, 48,000 Hz, and so on. There aresome cases where it is required to run the audio atpull-up or pull-down rates.The Rate Pull Up/Down options are:• Off – Normal use• 29.97 Up – If and only if the frame rate is 29.97 (DFor ND), then pull-up the audio clock rate.• 30.00 Down – If and only if the frame rate is 30.00 (DFor ND), then pull-down the audio clock rate.FreeWheelThe HD-P2 FreeWheel setting lets you adjust howmany bad, missing, or discontiguous timecode framesshould elapse before dropping out of a timecodeoperation (record or play). The options are from 1 to20 frames, or Infinite. After a timecode operation hasstarted when FreeWheel is set to Infinite the LTC canbe stopped or removed and it will still continue (Inthis case, you have to press the STOP key or run out ofmemory space or power to stop the timecode opera-tion).Jam SyncWhen timecode is set to Infinite freewheel, and a validtimecode source is connected, the internal timecodegenerator is started. While there is a signal, the HD-P2will continue to follow the external timecode. Shouldthe timecode stop, the internal timecode generatortakes over as the timecode reference until one of thefollowing occurs:• clock source is changed• freewheel setting taken off of Infinite• power cycleThis assumes that the internal clock, or somethingelse, does not stop when the LTC is unplugged. Youcan turn on/off the timecode (via keys) or disable/enable timecode, and the generator will continue torun.Trigger ModeWhen FreeWheel is not set to Infinite, a timecode opera-tion will stop if LTC is lost. If LTC restarts, perhaps ina different position, the HD-P2 will either start anothertimecode operation (Trigger Mode of Auto) or will waitto start another operation until the REC or PLAY keys arepressed (Trigger Mode of Single).Trigger on FrameOnce a timecode operation has been initiated (bypressing PLAY or REC with timecode on), the operationwill start either once any incoming timecode frame isrecognized (Trigger on Frame Off) or once a particulartimecode frame is recognized (Trigger on Frame On).Trigger-FrameIf Trigger Mode is set to Single, then you cam specifythe particular trigger frame in HH:MM:SS.FF format(Make sure you select Save and press the SELECT keyonce you have entered the frame number).Timecode OriginWhen a project is created with timecode enabled, ithas an initial timecode origin of 01:00:00.00. Thisdefines the beginning of a 24-hour “timecode day” forthe project. If an operation hits the end of the timecodeday (e.g. 00:59:59.29, in this case), it is stopped.Before recording audio into the project, the user canmodify the start/stop points of the timecode day tocorrespond with the range of external timecode thatis expected to be used with the project. For example,if the user is using 30 fps code, and sets the timecodeorigin to 02:00:00.00, the timecode day will rangefrom [02:00:00.00 to 23:59:59.29] and then from[00:00:00.00 to 01:59:59.29]. In this case, a recordingat 00:01:30.00 will be towards the end of the 24-hourtimecode day instead of near the beginning. Thismakes “recording over midnight” possible in time ofday applications.Timecode OffsetThe HD-P2 can offset incoming timecode up to +/-12hours during playback. This is useful when the userwants to line up playback with a timecode source thatuses a different timecode range than that used to origi-nally record the material into the project. An On/Offselection allows the user to activate and deactivatethe offset without having to reenter the numeric offseteach time. The word offset appears on the main displaywhen it is On letting the user know at a glance that atimecode offset is currently in effect.OffsetThis entry lets you specify the Timecode Offset inHH:MM:SS.FF format (Make sure you select Save andpress the SELECT key once you have entered the offset).
