9 – Operations related to timecode–Selecting the frame rate62 TASCAM DA-98HRtimecode previously recorded on the timecodetrack will be erased!).9.3.8 Checking external timecodeExternal timecode can also be checked in anotherway, as described below. This method is useful forchecking the frame rate of incoming timecode, if youare not sure what frame rate has been recorded or isbeing generated by the timecode source.1 Go to menu group E, and move the cursor toExt TC:2 Incoming timecode is displayed on the bottomline, together with the frame rate of thetimecode. If no incoming timecode is currentlybeing received, the screen shows dashes(--:--:--:--).9.4 Selecting the frame rateThe DA-98HR can use the following standards whenrecording and using timecode (including timecodesynthesized from ABS): 30 non-drop, 30 drop, 29.97non-drop, 29.97 drop, 25, and 24 frames per second(fps).When using the DA-98HR to chase to a timecodemaster, the system frame rate on the DA-98HR mustmatch the frame rate of the timecode master, other-wise chase operations are not possible.The frame rate is automatically set when a tapewhich has been striped with timecode is inserted, orif power is switched on with a striped tape alreadyinserted in the unit. The frame rate recorded on thetape is then used as the system frame rate.To change the frame rate in other cases, follow theprocedure below:1 Go to menu group 5, move the cursor to TCFrame, and press ENTER:2 Use the § and ¶ keys to change the systemframe rate for your project.3 The TC Track field shows the currenttape stripe frame rate and cannot be changed.9.4.1 Pull up and pull down (Fs shift)When working in film post-production with NTSCtelecine equipment, the frame rate of film (24 fps)and the NTSC color frame rate (29.97) do not form asimple mathematical ratio, and the sampling frequen-cies of either 44.1kHz and 48kHz are thereforeaffected on transfer back to film.To avoid this, pull up and pull down functions areprovided to adjust sampling frequencies to drop-frame rates, etc.1 Go to menu group 8, move the cursor to FsShift, and press ENTER:2 Use the § and ¶ keys to select betweenPull Down 30NDF, Pull UP29.97 NDF, Pull UP 29.97DF, Pull Down 30DF and Off.The triangular PULL UP and PULL DOWNindicators by the tape counter light if the set-ting is anything other than Off.NOTESThis setting is not memorized in the backup memory–youmust reset it every time the DA-98HR is turned off and onagain.The clock source must be set to INT when using the Fsshift function to pull up, and to VIDEO when using thisfunction to pull down.If vari speed is enabled (7.5, “Vari speed (pitch control)”), itis not possible to use the Fs shift function.When the Fs shift mode is operational, you cannot changethe timecode frame rate (see 9.4, “Selecting the framerate”).9.5 Timecode input and outputOnly timecode (not ABS timing) can be received viathe TIME CODE IN jack.The DA-98HR can, however, send both timecoderecorded on tape, as well as ABS timings as time-code, in addition to using this time reference for mul-tiple DTRS unit synchronization (9.5.2, “Timecodeoutput”).˘ E x t T C A b s D i f fT a p e T C R e l D i f fG e n T C A B S T i m e0 1 : 0 2 : 4 8 : 1 7 3 0 D FT C F r a m e M o d eT C T r a c k S y s t e m T Cn o n e 3 0 N D FF s S h i f t M o d eo f f
