SUPPLEMENTARY QUESTION:
Q: Why does latency seem higher for certain video formats (i.e. 24p, 25p, or 30p)?
A: TriCaster passes frames through the switcher at the appropriate frame rate. When the session
format calls for frames at 60Hz, displayed frames are refreshed much more often than (for
example) a 24p format. Consequently, apparent latency will also be less than half what it would
be at 24Hz. In general, the lower the frame-rate of the session video format, the higher latency
will seem to be.
A.8.2 WHY IS MY POWER SUPPLY BEEPING?
TriCaster 855 provides redundant, replaceable power supply units. When you i) disconnect or ii)
power down just one of the modules, or iii), if a PSU should fail, a beep is sounded to alert you. If
you wish, you can mute the alert by pressing the green button on the back of the unit.
SUPPLEMENTARY QUESTION:
Q: Where can I obtain replacement or spare Power Supply modules?
A: Contact NewTek Sales for purchase information for spare TriCaster components.
A.8.3 WHY DO SOME THUMBNAIL ICONS LOOK WRONG?
Some file formats (notably AVI) do not provide embedded aspect ratio information. As a result,
certain files (such as 1440x1080 files intended to be displayed as 16:9) the thumbnail image in
Media Player icons for may not be properly proportioned. Generally the problem does not
extend to playback (the DDR will ‘guess’ the aspect ratio correctly).
