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.

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.
You may prefer one of several simpler approaches that can be performed right on
your TriCaster. For example, if the clip will play properly in a DDR when the system
is not heavily loaded with other tasks, you could simply put the DDR on Program
output, click Record, play the clip, and stop recording. With a little trimming of the
recorded clip you'll have a very usable file.
Or, you can use SpeedEDIT – its Convert to SpeedHQ feature (found in the Filebin's
context menu) can easily convert a number of clips in a single operation.
F4V format files written by Adobe® Flash Media Encoder are incompatible with most
video playback applications (even those from Adobe). The developer has explained
the situation as follows:
"Adobe Flash Media Server version 3.5 and later and Adobe Flash Media Live
Encoder 3 can record content in MPEG-4 (F4V) format using an industry-standard
recording technology known as "fragments" or "moof atoms." Some MPEG-4
compatible tools and players do not support moof atoms, and therefore cannot
recognize files recorded by Flash Media Server. The F4V Post Processor tool
