Black Magic Pocket - Audio/Timecode on 3.5mm Jack?

Recommended Posts

Hey Everyone,

I'll be on a shoot soon with a Black Magic Pocket Cinema Camera. Previously I'd been using a QRX100 (feeding the 3-pin mini xlr), however production will have two mixers on the coming shoot with only 1 QRX100, so I may have to use another option.

Hence I was wondering if I could send both audio and timecode from a Zaxcom ERX into the Black Magic's 3.5mm input jack.

 

In the manual it says that the Camera will accept timecode into the left channel of the 3.5mm, does that mean that I can use channel 2 audio on the 3.5mm?

 

Cheers!

I worked a short film a few years ago that was shot on the pocket cinema. If the manual says it will accept TC, it probably will. Do a test.

However, I would suggest foregoing all that and simply use a slate, if practical. This camera is too small for mounting anything on it.

I just did some shoots with the current version of this camera and it all worked fine.  I sent audio to the TA3F jack and TC in through the left chan of the mini, then worked the menus to have the signals end up on separate channels.  The camera picked up the TC right away and made it into metadata TC for the camera files.  We mounted a small wireless RX (G2) + a small TC box (Moze) to the threaded hole on the cam for one deal, for the other the shooter had a camera cage that was easy to mount to.  BM has come a long way in the clarity of its menus--other co.s (like RED) should take note.  A side note--I ended up making my own mini>TA3M cables for the audio dfeed to avoid having to run through XLRs, which are kind of out of scale for this rig.

Note that there are three different Pockets, double check which one you're working with:

OG BMPCC
BMPCC4K
BMPCC6K

The two current BM pockets use the same connectors and menus and both do the mini input LTC>metadata TC trick.   We never tried getting TC into the older version of the camera, I don't think it had the ability to convert LTC to metadata TC, ditto with the super-weird original BM4k camera (the one with the 1/4" input jacks).

I worked with the pocket 4k 3 days last week.  You jam it through the 8th in microphone Jack.  

 

I had a couple issues with timecode drifting so I would rename hourly and you will be fine for sure.  

 

I only jammed at battery swaps and at lunch and we had some drift on 3 out of 50 takes.
