BMPCC and ZOOM H6 in sync

Good morning

This is the first I post here and my englis is not very good but I try.

I have built a remote that can start and stop the camera and the ZOOMH6 in sync.

I have take something like 10 shot and I have 3 frames off , everytime.

I use the remote from the H6 and I manage to put Inside the H6, a lanc controler that I built from a Teensy module, similar to the arduino, but this thing is small enought so I was able to fit it Inside. It's working like magic.

Now I have 3 cable coming out of the H6 remote, 1 lanc for the camera, one cable for the switch and 1 for the H6. Yes, I have to control the camera and the h6 whit a external switch out the the remote of the H6

Well, I would like to put some photos but don't know how. I try later if someone is interested.

As long as you can adjust this all in post, I would not spend much time trying to trouble shoot this one.

Shure! 3 frames is really not a problem. And it seem to be constant. So I am very happy whit that.

More important than the "in sync" recording is that you can't accidently forget to start the H6 (or the cam)...

And whit fresh format in camera and h6, bot whit the same date, hrs, min, sec, all files will correspond when import. no more mess finding correspondance betwen audio and video

So ¿Does the ZOOM H6 has this sync problem after long shots of 8 to 10 minutes, like the H4 or the Tascam DR-100mkII?

This sounds really good - would love some more info/details

From my (limited) experience every combination of camera and audio-recorder will start drifting after a couple of minutes, unless they are sync-locked. And this is the cameras' fault as well as the audio recorders'. I've done a lot of low budget multicam gigs, mostly concerts and musical events where a number of cameras had to record unattended and uninterrupted, and it seems i never get even two cameras that won't drift several frames over an hour. God i love Pluraleyes...!

Nevers make shot that long, but I Am going to test This.

What kind of info are you looking for?

Here is a image of the remote

I have done a test this morning, and over 10 min 30sec, there is a différence of .06 millisecondes ( 1/5 of a frame ) between H6 and Bmpcc. This is quite acceptable for me.

I have done a test this morning, and over 10 min 30sec, there is a différence of 200 millisecondes ( 1/5 of a frame ) between H6 and Bmpcc. This is quite acceptable for me.

Thank you, I was wondering this for a while, as Mac Jaeger says there always will be audio drift, I definitely got to own Pluraleyes.

Actually i'm only using pluraleyes to auto-sync multicam recordings; when combining separate audio tracks to singular video recordings i usually timestretch the audio part manually.

200 milliseconds is a fifth of a second. That would be 5 or 6 frames. Clarify?

Rick, thank's to correct This

You are right, I should have say 320 units in première or maybe .066 millisecondes.

There is 1600 unit per frames. Anyway it's really 1/5 of a frame over 10 minutes, not 5.

Sorry about that

That makes more sense, i guess. 1/5 of a frame audio/video delay is hardly noticeable, i would only care about correcting it if i had to mix audio tracks.

Hello everybody,

I got a big question to your sync solution.

It is unclear to me how it work in detail? Only the posted picture does't show (me) how you solved the issue to send a LANC signal to the BMCC. I can only see the 2.5 plugin, but from where did you get the needed LANC electronic? (The remote of the H6 does not work with the Sony Lanc protocol.)

Did I oversaw anything?

Hope to get an answer ... Thank you very much in advance!

Alain,

meanwhile I saw what I overwrote. You you used a Teensy Lanc module for your sync solution.

But how did you connect the components (H6 zoom control, switch and Lanc module in detail?

The zoom remote and the Lanc module are working with different voltages. So it is possible to destroy electronic components!?

Did you use a single pole or an multi-pole switch? And how did you connect it in detail? Is the zoom remote control equipped with screws that it can be opened without any problem?

Thank you very much in advance!

Hi Juergen,
Yes I use a dual pole switch.
I have Somme photos here https://www.flickr.com/photos/13862965@N08/

The top of the h6(buttons) are glued, so whit care it's easily removable, under this, there is 4 screws.

Then you have to sculpt a bit in the plastic to be able to insert the teensy.
You will have to find where to solder the wires on the h6, as you can see on the photo.

Whit some care This not so complicated. Put some tape on the teensy so there is no short between both board when assembled.

Hope this help
Alain

Hello Alain,

thank you very much for reply. Especially the issue with the glued top is an essential information.

And wouw!!! What fantastic nature pics. !!! You have got an real "photografic eye" and ... much experience to make those kind of photos. I really do love nature too!

I will try my best to copy your sync solution.

Best regards

Tank's for your comment Juergen, and if you have any question don't esitate.

Alain

This sounds like something I would like to try on The new micro camera. Do you still have the pictures of tour solution? Old link seems to be broken. And also, do you think it would be possible to use the aputure lensregain remote as start stop for both h6 and bmmcc?
