Time code audio tracks in NLE?
Various places I've worked have found different solutions. Some record the LTC from a broadcast video tape to an unused track. Some will reuse a track from an earlier project. The first is slow (1:1), and both are inflexible. Hardware TC generators are flexible, but it's still real-time creation.

I offer a free 32-bit Windows utility that can generate an hour or more of SMPTE/EBU code as an audio track (WAV file) in a couple of seconds, at any common frame rate. No catch, it's free for any use, personal or pro. I only ask that you pass along This Link, and not copy/share the program directly. Enjoy, and please send comments or suggestions.
