Grzegorz Kwiatkowskiworking with SMPTE timecode
by on Nov 11, 2011 at 7:47:55 am

Hello,

recently I finished shooting program series for tv. Times are hard for small thematic channels and the budgets are low so I decided to shoot on two Canons 5D and Zoom H4N recorder. I edit everything with Vegas. All looks really good but syncing is a horror now and editing takes twice as much time.

Next time I want to use cameras and audio recorder which have the timecode SMPTE feature. Has anybody worked with multicam production (for example Sony EX) that had cameras (and audio) synced with timecode SMPTE? How does it work in Vegas? What is the whole pipeline?


thanks for professional help

If you mean syncing the audio to the video, do what everyone else is doing and use PluralEyes.
BTW, when I say "everyone", I do mean everyone.
I read about this software on several Vegas forums as well as pro audio forums and no one has had anything bad to say about it.

Mike,

I bought Plural Eyes and it's not perfect. For example when you film from the distance and there is big noise near the camera (or the camera doesn't "hear" the actor because it's behind the glass), Plural Eyes is useless. SMPTE is the solution.

Plural Eyes is efficient if you produce in a quiet studio in one room.

I agree, and no, NOT everyone is using Plural eyes!

SMPTE is nice if you got cams with a TC in function, but can be used with any device if you have an audio channel to spare.

A very cheap TC generator is Jumpstart, available for Iphone/pad.
But any device that can play back sound will do. (SMPTE / LTC is an audio signal)

Some nice info is here:

And yes, i'm biased, as i'm the creator of the software mentioned...

Nice.. Do I need timecode generators connected all the time to each camera (Canon 5D) that will send TC signals to the audio tracks?

Yes, you need TC connected all the time as the internal clock of the 5D drifts horribly.
(You know they get hot, probably causes that...)

But you only need the first few seconds of each clip to have audio timecode, so you could start record and disconnect.

But since it is a very simple audio signal, any half decent AM/FM transmitter / receiver will do to distribute the signal wireless.
So you could use Jumpstart with a transmitter / multiple receivers and there will be no need for Lockit boxes.

And you can of course use cables.

It highly depends on the kind of shooting you do to decide what's best.
Do toy with it, i can send you some audio timecode if you like.
(Do specify the framerate though...)

Bouke, I would appreciate if you sent me the video file with the timecode recorded in audio stream.


thanks!

Maciej

no problems. I assume you want 25 FPS?

Watch out for the correct channel the LTC lives on, these are some random clips.

there is also 1 hour of LTC in a Wave file, so you can run your own tests.
(play back from any player and record the LTC both on your cam and your Zoom. There is also a WaveToBWF application that can convert the waves to BWF based on the audio tc)

hth,

Bouke
