TV Format
Allows you to define the television format for time code burn-in:
PAL: The video format used in Europe. If you are working with video in SECAM Norm,
select PAL.
NTSC: The video format used in the USA and Canada.
You don’t just need this setting when writing and reading VITC. If you’re working with
LTC, and you want to generate a video picture a with burned-in SMPTE time, you also
need to set the correct format here.
VITC Line 1, VITC Line 2
VITC is written into two lines of the video picture, which are normally invisible. The lines
should not be adjacent, and are usually situated between 12 and 20.
If “Scan” is enabled, the VITC lines are automatically recognized. You should only enter
the lines manually if there are problems with “Scan” mode.
Visible Time Code Display
The parameters allow you to set the position, size, and color of the time code counter
window, which is burned-into the video picture.
Bar Ruler—Time Ruler
Positioning Bars to Frames
If you want a particular bar in the song to coincide with a specific SMPTE time, you
need to alter the tempo of the preceding passage.
The following procedure will save you from having to do this by trial and error:
1 Open the Tempo List (see “Tempo List Editor” on page 448).
2 Create a tempo event at the desired bar position.
3 Set the desired time position for this tempo event in the SMPTE-Position column. The
preceding tempo event is automatically adjusted to generate the correct bar and time
position for the inserted tempo event.
4 You can then delete the tempo event you inserted, if you want to keep the same
tempo for the following passage.
