TriCaster’s ‘double-rate’ MPEG-2 format for records is comprised entirely of ‘I-frames’, resulting
in excellent image quality. Two variants are provided; your choice principally affects color
sampling applied to captured clips:

MPEG-2 Compatibility encoding invokes 4:2:0 color sampling (similar to that of the
popular ‘DV’ and ‘HDV’ formats).

MPEG-2 High Profile encoding raises color sampling to 4:2:2. These files retain more
color information than standard DV/HDV files as well as many other file formats. The
increased color fidelity is especially valuable for chromakeying purposes. (Please see
the notes which follow regarding file compatibility.)
COMPATIBILITY CONSIDERATIONS
The 4:2:2 sampling and high fidelity of the MPEG-2 High Profile format make it especially suitable
for chromakeying applications. Support for High Profile MPEG-2 files by various applications is
not universal, however. It would be prudent to test file compatibility with your favorite third-
party programs before making extensive use of this option.
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.
