AVI

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.

* Note that, to maintain good image quality at low bitrates suitable for online

use, Web Quality recording is always 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.

Sources
pane of the Record Configuration panel. A Switch next to the Secondary
