4. Use the Import Media module that opens to create a list of files you wish to import into

the current session, and click the Import button.

Selected files are automatically copied to the appropriate folder (Clips, Stills, etc.) according to
their file type (see Import Media, in Section 5.3).

Hint: You may know that external files can be used in a session without being imported, by adding
them to Media Player playlists using the “Add Media Location” feature. However, such external
files used in a session will not be included in session backups (unless they are deliberately
imported during the backup process), nor are they deleted when sessions are deleted.

Also, the transfer speed of many external devices is too slow for reliable playback of media
content, making it wise to use Import instead whenever possible.

A.4.4 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 format can serve for either SD
or HD clips, and represents a high quality, moderately compressed alternative. (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).
