Power ZOOM Lenses on the ATEM with a Pocket Cinema Camera

Photo Moment - June 10, 2021

If you have a powered zoom lens and a Blackmagic Pocket Cinema Camera (BMPCC), you can probably control it from the ATEM Software Control when connected to any ATEM — here's how!

Need an ATEM Mini?

What this tip is about…

In the previous ATEM (mini) Tip 11 I showed you how to control a Blackmagic Pocket Cinema Camera (BMPCC) through the ATEM Software, and in the case of the ATEM Mini Extreme or ATEM Mini Extreme ISO, even from the hardware. However there was one thing I left out — zoom control. That's because to control zoom on a lens, you have to have a powered zoom lens. After all, without a motorized zoom, how could the camera possibly zoom the lens for you! I recently had a Canon CN-E 18-80mm T4.4 COMPACT-SERVO Cinema Zoom Lens in the studio for a project, and quickly shot this video while I had it. I even figured out something interesting about zoom control and ATEM macros that I had never seen before. Check it out!

This video is by request! Lots of people wanted to see how the power zoom works, so here you go 😁 What else do you want to know? Also, please subscribe!!
Awesome, thank you for watching!
@Band Of Heroes Second that! Very nicely done, @PhotoJoseph!
Thanks again, PhotoJoseph. Really appreciate the time invested, super helpful!! My next new question regarding the BMPCC 4k: How do the recordings settings in camera affect the HDMI output. When using the BMPCC on the ATEM Mini via HDMI I have noticed that it seems to make a difference what codec and/or resolution has been chosen on the camera's menu. Sometimes the format of the image via HDMI seems to change slightly (adding black bars on top an bottom) etc. Any idea what might be the cause?
That’s because a format of C4K has been selected, which is a 16:9 aspect ratio. Codec will make no difference (codec refers to internal recording only), but aspect ratio, size and framerate all are reflected on the HDMI output.
@PhotoJoseph thanks! Next time I have a BMPCC around I'll try and go through all possible combinations of that and see what happens..
I love your training segments . . . this one was very informative . . .
Thank you kindly!
one thing I have noticed using the ATEM with BMPCC, with the SEETEC ATEM 4 input monitor. It doesnt pass the camera controls through the HDMI ports. Shame.
That's interesting. They must no be passing the full HDMI protocol through their ports. Bummer.
Just an idea:
Stop zooming with hitting a additional macro with "0".

Can't verify myself as I do not have a BMCC.
Can you toggle the macro run button to suspend the zoom?
No, that would just start it again. But someone suggested sending a command of “0” which appears to be “no movement” and maybe that’d stop it.
Cool discovery, thank you!.
Has anybody a tip for a good mft Power-Zoom lens?
To stop the zoom where you want just create a macro with the zero value again! With the macros you've created it continues to press the button for infinite time. More exactly, Even when the lens reaches the max/min zoom it continues the effort like you are still pushing the button. So giving the value of zero again it stops! Even in the middle!? (I suppose!)
@PhotoJoseph i'm assuming! It seems logical to me even though i don't have any expert programming skills. If you give it a try, please tell me the results :)
I was struck by the same thought. When you recorded the macro the first time you had released the zoom control and it had returned to the center position (no motion). You then discovered that changing that value caused the lens to move in a specific direction and speed which were dependent on the sign and value, 1.0 being the fastest movement. Since this number defines speed and direction a 0 would logically be don’t move (stop). Would be great is someone could confirm or disprove this.
Another assumption would be that for those who use Companion and StreamDeck to run macros, the not-zero values on Press Button, and zero value on Release Button would create a satisfying zoom function.
@Volleykanalen that it would. Ok I gotta test this!
@PhotoJoseph Would be awesome to hear if it did work or not :)
This is fun. But for the price of this lens... I'd rather just see a 4k capable Atem Mini Extreme come out one day and then just crop in with the switcher or in post (being happy with an HD quality frame).
That's not the only lens of course… there are other motorized lenses. For me the biggest problem with them though is the cheap ones are usually variable aperture.
I have used the bigger Black Majic mixer with the remote that allows you to do everything with these cameras. I find it funny seeing all these high end camera being used on ATEM which only handles HD.
haha totally. I use a 2 M/E in my daily production, and it's constantly back and forth between UHD for internal production and HD for streaming.
