Note: TriCaster’s High Profile MPEG-2 files meet the “High Profile” MPEG-2 definition established by the Moving
Pictures Expert Group (MPEG). Please see http://en.wikipedia.org/wiki/Mpeg2 for more detailed information on
High Profile MPEG-2 encoding.
AVI (S PEED HQ)
Selecting AVI (.avi) encoding tells TriCaster to capture the designated source using NewTek’s native AVI
format, called SpeedHQ. This is a high quality, 4:2:2 file format suitable for both SD and HD applications. (See
the hint under Encoding above regarding NewTek codec packs to use this option with your favorite
applications.)
H.264
Another important encoding type is H.264. TriCaster supports two different bitrates, designated High Quality
and Web Quality. The former uses 8 Mbit/sec CBR encoding and session format, while the latter option uses
a 2 Mbit/sec bitrate. (You should be aware that, to maintain good image quality at such low bitrates, Web
Quality always records in standard definition format.)
Note: H.264 encoding is processor intensive. To avoid dropped frames, this format should only be used to encode
one video stream at any time. Also, be aware that if an unexpected condition (such as a power outage) should
interrupt recording, incomplete H.264 files cannot be repaired. For this reason, we recommend Quicktime or
MPEG2 formats for critical mission capture, with H.264 used only for redundant recordings.
20.1.3 REPLAY TAB
In TriCaster Advanced Edition, features related to instant replay have been gathered into the Replay tab.
