Thanks.
For some bizzarre reason known only to Adobe, Premiere still doesn't recognize a BWF file's timestamp. But Audition does ... you load the video clip into a multitrack session in Audition, align it properly on the timeline by setting the timeline offset, add the sound clip with the option "Use BWF Time Reference As Insert Start Time" to sync it, and export the result as an AVI file with both video and sound tracks. Audition even has a workspace preset of "Video + Audio Session" predefined out of the box.

Yep, and my comments were assuming it was to be a film-style double system workflow of recording to a completely separate audio recorder without also recording an in-camera scratch track to use later for sync. Recording both would be a different matter but I still think a tone extending over time such as you'd get from recording the alignment tone would be harder to sync to accurately than would a single impulse sound.

Steve,
You may want to look at a "Bloop Slate" also called a Bloop Box. I haven't used one in years but there seems to be a use for them again. Used with a nagra, the bloop box would put a tone on to the tape while displaying a sync light for the camera or cameras. The topic has been covered over at jwsound. I believe there is even a schematic.
Cheers
Jon

There are also iPhone and iPad apps for slating with a sync tone and visual flash, as well as all pertinent project/camera info.

As Mr. Goodman observes, "bloop slate" was the standard for many years for lots of 16mm budget production, especially local TV news, etc. And if one prefers an "impulse sound" key the slate mic on and snap your fingers. :-)

Thanks Jon. I've read about these but haven't yet found out where to get one (if it's still even possible).

Ugh. Seems like it would be easier to just use a dumb slate!

They haven't been made in decades.
Dunno why anyone would need one?

* Press tone button for audible sync signal. No Cost.
* Hold notepad in front of camera for scene/take numbers. No Cost.
* Sync and Slate. Done. Priceless.

(With apologies to MasterCard)

I have had an idea kicking around the brain for a while for a simple sync setup... a couple of hours in the workshop and came up with this......

It's not expensive and is a very valuable tool, much more capable than Soundbooth
