Recording with PTLE locked to SMPTE

[Jeff16years]

i do this with an oo2rack

my opinion is:
you need the MOTU digital timepiece, this works better than the current model called something like timepiece AV.
You need the DV Toolkit 2
and you need an external clock source.

Why does the MOTU Digital Timepiece work better than MIDI Timepiece AV?

What about a MOTU MIDI Express XT or micro express?

Why do you need an external clock source?



I have only done SMPTE sync in Pro Tools HD, so I appreciate the help.


more posts, please Thought? Comments?

sorry, i realize i was a little vague.
What are you trying to do sync to video?

A band or singer/songwriter will be setup onstage. There will be 2 or 3 video cameras and I will be recording audio (and more then likely mixing and mastering it later on). The owner of this place where I will be recording wants to record using PT LE.

I am just looking into all of my options. I prefer DP to PT LE, but a gig is gig.

I don't know at this point. I haven't met the video guys. I would hope for video black burst. (I hope I'm not the only professional on the gig. )

Thanks for the DUC link. Is that how you are doing it?

yes, this is how i'm doing it. It works GREAT.
Here are the specific instructions that I received from someone a lot smarter than I...

You'll need to convert the SMPTE BNC to a 1/4 inch to feed to the DTP SMPTE Input.

The BNC with video will plug into the DTP Video In BNC connector.

The Word 1x BNC on the DTP will feed with a 75 ohm BNC to BNC cable to your Presonus Word Clock input.

The S/PDIF out of the DTP will feed to the S/PDIF in of the 002/R with a 75 Ohm RCA to RCA S/PDIF cable. (optional since the Presonus will have the DTP clock too)

The MIDI 1 Out of the DTP will feed to the MIDI In of the 002/R with a MIDI cable.

In Pro Tools 7 in the Setup menu -> Peripherals... On the Synchronization page select Generic MTC reader and set it to the MIDI In port of the 002/R.

In the Pro Tools Session Setup Window set the clock source to S/PDIF or ADAT. (You can use either since the clock source is ultimately the DTP if you've hooked up the S/PDIF as above).

Make sure the session start time is earlier than the code they're sending you.

On the DTP set the source to Video and SMPTE. Set the rate to the correct setting (48kHz I would imagine). The format to 29.97 (or whatever you require).

In the Pro Tools Session Setup Window match the frame rate setting.

Put the Presonus on external word clock

Put Pro Tools online (Option+spacebar or Command+J)

If you have incoming LTC/SMPTE Pro Tools should start chasing it in synch.

I just want to chime in that I've had my Digital Timepiece for almost ten years and to this day, it is one of the most useful tools I have for interfacing practically anything to anything. Whether you're working with synchronizing gear made 30 years ago or last week. Video-audio-midi....anything. The thing just never fails on any combination of sync I throw at it.

It always amazes me that the DTP is so unknown to so many people.

i was on a tv show where the A1 was trying to use the newer Midi timepiece A/v and it would work for about 5-10 seconds. Then someone told me that the DTP was a more stable unit (at least for doing what we were trying to do)
then about 1 year later i was on a different show, i got the DTP (for a mere $100 on ebay) and it worked perfectly. Now, i'm not saying that there wasn't any other factors when I saw the other unit not work, but I took the advise I received and it works great.
