A.6.2 PREPARE CLIPS WITH EMBEDDED ALPHA CHANNEL?

Probably the best format to use for files with embedded alpha channel for use in TriCaster are
those encoded using NewTek’s own SpeedHQ 4:2:2:4 codec. This represents a high quality,
moderately compressed format. (As a registered NewTek customer, you can download the
NewTek Multi-Codec Pack from your personal Downloads page on the NewTek website.)

Apple® computer users have several options available which support an alpha channel, including
the Animation and PNG Quicktime movie codecs (select “Millions of Colors +” in the codec
settings to include alpha in the file).

A.6.3 PREPARE CLIPS FOR TR ICASTER PLAYBACK USING APPLE® FINAL CUT

PRO?

For SD video files exported from Final Cut Studio™, choose either DV or DVCPro in .avi format.
(Alternatively, export a DVCPro .avi file from Quicktime Pro.)

A.6.4 EXPORT FILES FROM TRICASTER FOR USE IN APPLE® FINAL CUT PRO?

At the time of writing, importing MPEG-2 files recorded by TriCaster into Final Cut requires a few
extra steps, as described below:

1. Record your files with Use MPEG-2 Studio Profile switched off (for more information,

see Section 6.10.1).

2. Import the files into Final Cut. A red bar will indicate these clips need to be rendered

within the editor. After rendering, they should be available for editing like any other
clip.

A.6.5 IMPORT/EXPORT FILES LARGER THAN 4 GIGABYTES?

This question may arise if you are using external media, perhaps portable hard drives or USB
‘thumb’ drives. These are commonly prepared using the FAT32 file system, which does not
support files larger than 4GB. As video files will often exceed this size, FAT32 is not very suitable
for use in that context.
