QUICKTIME™

At the time of writing, a 64bit version of Quicktime™ for Microsoft Windows™ is not available.
TriCaster provides internal support for many QuickTime file formats, but not all of them. If a
QuickTime file fails to play smoothly (or at all) in the DDR, we recommend converting it to a
friendlier format.

Final Cut™ users might consider M-JPEG, MPEG2, DVCPRO HD, or the DV Quicktime codec (for SD
clips only, of course) as intermediate formats. In some cases you might be successful using
SpeedEDIT to convert QuickTime files that fail in the DDR (SpeedEDIT’s Quicktime codec support
is more extensive).

AVI

AVI codecs are plentiful. Most are suitable for DDR playback, but a few are not. For a given clip
to play in the DDR, a corresponding 64bit codec needs to be available. However, we strongly
discourage installing ‘foreign’ codecs, codec packs and the like downloaded from internet sites,
etc.

For the sake of stability, if an AVI clip does not play well in the DDR, please consider converting it
to a ‘friendlier’ format. We can recommend NewTek’s own SpeedHQ, or perhaps DV (for
Standard Definition clips), M2T or MPG – please continue reading for more information on file
conversion.

REMUXING CLIPS

Even when a specific AVI exists and can generally be considered ‘friendly’, the manner in which
audio and video data is multiplexed (or ‘muxed’, in the jargon) by some few applications can
cause playback issues that are only evident under stress. That is, a clip that plays back
adequately in a typical player or NLE application may not do as well when played in a DDR at
times when many other concurrent operations are occurring simultaneously.

In general, remuxing such files is all that is needed to obtain good performance. One approach is
to use any of a number of freely obtainable remuxing utilities. A quick internet search for
“remux avi” turns up several applications you could use, some free. Installed on an external
system, these will remux AVI files losslessly, resolving the issue.
