Using the 4:3 Mask in 16:9 mode
Sometimes when viewing 16:9 footage you may want to know what part of the video will be seen on
4:3 monitors for both picture composition and titles. The 4:3 Mask function of the TLM-170H allows
you to do this easily by pressing one button during normal 16:9 viewing.
This 4:3 mask can be set as transparent or overlay within the
Special Function
I
menu. The
Transparent setting allows the 16:9 video to be seen through the mask. The Overlay setting does
not allow video to be seen outside of the central 4:3 area.
To toggle the mask overlay on or off press the UP button during normal 16:9 viewing.
Displaying the 80 / 90 % area frame overlay
Television standards do not currently define the official size for overscan or underscan areas of video
displayed on televisions and monitors. Different makes and models of monitors can show less or
more of the video area that was actually captured by the camera. To ensure any overlaid titles are not
cropped off the displayed video area of any monitor safe areas of 80% and 90% were devised by
production companies.
The
Special Function I menu allows a choice of off, 80% or 90% for Frame Ratio. By pressing the
down button during normal viewing the 80% or 90% Frame overlay will be displayed or turned off.
