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.
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.
FLASH (F4V)
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 aggregates the information from all the moof atoms into a
single moov atom and outputs a new file”
