Timecode / Logging networks (ACN and TCB)

Something which seems to have been gradually appearing is how all the data about what we’re shooting is now able to be logged and centralised much more easily. You can now run a computer network on set where script supervisor, camera and sound’s notes can be compiled together and matched to all the individual files.

Two different systems have started to emerge (very recently), Ambient’s Clockit Network (ACN) and Timecode Buddy (TCB) and related products. There’s also the Cameron-Pace metastrobe system, but I haven’t seen any documentation on it (and imagine it’s very expensive to hire).
ACN has been in development for some time and started appearing on Ambient’s newest series of lockit boxes (ACL204). They’ve had this video up since it began:

Ambient have also teamed up with a company called Easyscott to deal with their logging and metadata distribution. It seems to be a powerful system, although it requires having a server on set which someone’s got to look after (they suggest the 2nd AC). Logging currently works on iOS devices but they’re planning compatibility with other tablets in future. The server’s also able to deal process a video feed, so playback can be done over the network, rather than the camera, which may save some time on set.

Something else Ambient have been talking about with ACN is actually being able to read/write metadata directly off machines via RS232/RS422. They had a demo of this working with a 3D camera rig at last year’s IBC (http://youtu.be/YNNUnBpo_NI?t=4m17s), where metadata was updated on a tablet but I’m yet to see it implemented in any audio recorders. I’d expect the manufacturers who have implemented ambient TC units in their products to be those working with this, however not all have an RS232/RS422 port on them (Sound Devices 7 series do, though). Ambient have also just announced new slate/TC display which works on ACN.

Timecode Buddy are the new kids on the block as far as timecode systems are concerned, their system works in a similar way to ACN (where timecode data is transmitted over wifi), but they also have a UHF range transmitter for transmitting TC between units.

They’ve teamed up with MovieSlate, who make a slate and logging app, which has developed into quite a powerful logging tool which will talk to TCB and receive timecode. I use it for sound reports, but with all the multicam plugins etc multiple iOS devices can share info across the network and receive matched timecode. Buying the app does add up though- it’s £17.50 for the app (on each device), but then another £35 each for the timecode, multicam and sound dept add-ons (making £122.50 per device). I don’t think there are any plans on moving movieslate to any other platforms and TCB have said they can only get the devices to display accurate timecode on devices where they know the hardware delays etc, so if making something for android they’d have to know every model of phone/tablet that would be compatible.

Denecke have also got onboard and are developing a slate which will receive TCB network information: http://www.youtube.com/watch?v=tl8jf_8gIOg

Finally, Movieslate are also working on adding a video feed from a Teredek Cube to the logging screen- so a live picture (or pictures) can be seen from the iOS device.  TCB are also working with Adobe in order to add timecode to their prelude live logger.

Both systems look very capable, ACN/EasyScott looks like it’ll be able to do a bit more in future- but involves a more complex setup, while TCB/MovieSlate seems to be a bit more portable, as you don’t need to move a server around with you (and find power for it).

Time will tell whether one will be VHS and the other Betamax…
Zaxcom’s zaxnet system already sends audio and timecode around set, maybe metadata will be added to this?
