As explained in Player Assignment to File Types, INTERACT uses different player engines when the Windows Player is selected.
But even the default INTERACT Player extracts some important information from this dialog:
▪Click General - Program - Settings
.
▪Switch to the File Extensions tab:
Known File Types
All extensions entered into the Video field, are considered to be known video types and will be listed in the file open dialog of INTERACT.
Those extensions are valid for both INTERACT on MacOS and Windows.
Add a new Extension
If you can play your multimedia file(s) in the Windows Media Player or the VLC Player, there is a very good chance INTERACT can handle that video*:
▪Enter a semicolon [;] and the extension you want to add into the Video text field (Like this *.nxt).
*For the Windows Player, you do also need a fitting DirectShow video Codec, to make things work.
Recalc Duration*
Especially MTS and M2TS videos do not provide reliable duration information in their properties, which results in unexpected, irregular behavior in INTERACT.
For video types listed in this field, duration is recalculated on open by the INTERACT Player, resulting in accurate controlling.
Note: Depending on your access rights, you might need to restart INTERACT before your changes are applied.
*) Only available for the Windows-based version of INTERACT
