Time code slate

I'm just entering the wonderful world of syncing camera and external sound recorder with time code.. (I now have a Sound Devices 664) My question is...why use a time code slate if the camera and audio recorder are recording at the same frame rate and the time code is jammed? Once the files get to post they should be "easily" ( I know, nothing is easy) matched as the frame rates are equal and there is time code stamped on each take? What am I missing?

Your missing time code drift between the recorder and the camera depending on the accuracy of the internal clocks. You can use a dumb slate with no TC and use the clap and sticks closing to align the audio & picture. Works very well. Feature films still use the dumb slate today.

I'd add that if you're recording long programs, the just timecode won't sync audio & video for long. The sync will drift. What's usually used is a master clock that generates both word sync (which the SD can use) and video reference (for the camera). However, none of the Blackmagic cameras have a genlock input, so that's not possible. If you're shooting short scenes, then no problem. Otherwise, you'll have to adjust sync in post by cutting the audio when you lose sync and slipping it back into sync.
