do I need SMPTE generator?

Archived from groups: rec.audio.pro (More info?)

I want to make some instruction DVDs (blues piano, music theory, etc);
I intend to edit the video with Premier and create/edit music/sound
with Cubase, both running on a PC. Do I need a SMPTE generator (such
as I would get with an Emu 1820M), or will I be able to work with just
an audio interface (all sync being controllable within the
applications)?

Thanks for any help,
Gerard
