PYXIS 12K Initial Issues

So I have had the Pyxis 12K for L-mount for about a week now and have noticed a few issues that I hope can be fixed via firmware. Has anyone else experienced these issues?

1. For some reason, stabilizing footage using gyro data has given me poor results. It will either zoom in a ridiculous amount/warp image or won't help the micro jitters. I am using the same lens that I have on a BMCC 6K and it's not even close. I have calibrated the motion sensor multiple times and made sure the lens data is correct. The best way to stabilize my footage right now is by using Perspective but would love to use gyro data.

2. Screen will blackout sometimes when switching resolutions (have to reboot camera).

3. Pyxis monitor touch functionality won't work occasionally when switching resolutions (have to reboot camera).

Hi,

They definitely sound like issues that can be fixed in firmware if we are able to reproduce it.

1. What lens are you using?

2. So just going into MENU > RECORD and then selecting between 12K, 9K, 8K and 4K etc? Do you have to press the or exit the menu such that the camera actually switches resolution in order for the issue to show up on your camera?

1. Sigma 28-70mm DG DN Contemporary (L Mount)

2. Yes, for instance changing from 12k to 8k to 4k. It would occasionally black screen if I changed resolutions too quickly. I would just turn the camera off and on to reset it. I haven't tried another solution.

Just a note to say that I've had all three of these issues on mine. I've also had the Pyxis monitor just be completely unresponsive (while showing the image), and in that case I've had to start recording with the physical button on the side of the camera or reboot the camera. I think I'm going to send mine back but it does seem like firmware could eventually fix all of these.

Is the PYXIS Monitor on software v1.6? Plug it directly into your computer with the Camera Setup software and you should be able to tell, and upgrade if it is not.

I just tried the gyro stabilization on a handheld walking shot and the in camera gyro did much better than the perspective, which gave micro jitters, etc.

Other times I've found the perspective did better than the gyro for slightly shakey shots.

I have been having issues with the 12k Pyxis L mount camera blacking out randomly.
The camera screen goes black and the camera buttons are unresponsive.
When I had an external monitor on the picture kept displaying despite the seemingly dead camera. The monitor is connected to the SDI port.
I have tried different batteries and the power supply to no avail.

Any solutions would be appreciated.

With the red shift on my Pyxis monitor I tolds BMD Support the firmware on my monitor I updated to version 1.6 but BMD support still ask me to update with camera firmware version 9.9

Can you just RMA the monitor? Doesn't sound right?

1. Are you using the PYXIS Monitor? If so, were you connected to the front or rear USB port?

2. What were you doing just before it crashes?

I am not using a Blackmagic monitor and was connected to the SDI port.
It crashes after about 10 seconds of being turned on.
Last time it blacked out 3 times and then ran fine after that.
I have turned the camera on today with both power supply and battery and have not been able recreate the problem.
Sometimes it blacks out during playback if I select a clip and push play. Not doing that at the moment.
I shall persist in trying to isolate the problem?

Thanks for your determination to reproduce the camera black screen. Interesting that the external SDI monitor is fine. So that helps marrow down where the problem lies. Perhaps it’s the handoff to /from the playback.

The Pyxis 12k blackout is caused by having two Angelbird AV PRO SE MK2 CFexpress 4.0 Type B 2TB installed at the same time. If I take either one out it doesn't crash. When I put both in it will crash a few seconds after startup or when I try to play back clips. The external SSD doesn't effect the situation.

Is this fixable with an update? Or a hardware fault in the camera? Or something different?

Ok that's interesting and we'll check it out here. Initial thoughts - probably a firmware / software fix.

Is it possible for you to send us a diagnostic log if you can reproduce this again? So connect via USB to your host computer and in the Camera Utility, you should have a "Save Diagnostic Log" button in the setup section right at the top.

I was advised by BM Australia tech to format cards.
I formatted to Mac (they were exfat) with no improvement.
I then reformatted to exfat and so far all is working just fine.
If it happens again I will definitely send a diagnostic log.

Unfortunately it didn't stay fixed for long. I'll get on to the diagnostic log done.

Good advice but I don't have an Angelbird card reader so I cannot upgrade.

How do I enter info into Camera Setup. It is whited out and I cannot activate the Save Diagnostic Log.

Angelbird does not have any CFExpress B cards that the recommend for the Pyxis 12K or the URSA Cine 12K. The 2TB is not on the Blackmagic recommended list, although the CFExpress 4.0 B 512GB and the 1TB is.

The 4.0 cards are dual lane PCIExpress 4 that have to change to single lane mode to work in cameras. No camera is made that has a PCIExpress 4 interface.

RED’s V-Raptor had to go though 7 firmware revisions to support the Angelbird AV PRO SE CFexpress v4 Type B cards vs. the AV PRO CFexpress MK2 Type B and AV PRO CFexpress MK2 XT Type B cards. They still don’t support the v4 Lexars, just the older 1TB and 2TB Gold series.

The card works perfectly but not with 2 in the camera.

You're right, according to the recommended list dated October 28. I was looking at the earlier list from September 25 athat only listed 14 cards, not the current 35 cards. I also was referring to the URSA Cine 12K list from January, not the October 14 list that includes the v4 cards.

That's a shame that you can't record to 2 cards simultaneously to access the higher record speeds.

Since those CFExpress 4.0 cards are listed as having a sustained write speed of 3,150 MB/s with both lanes, does that mean that a single card can deliver 1.5 GB/s on a Pyxis 12K, at 9K 2.4:1 80 fps constant bitrate 3.1 1.5 GB/s 22.9min/2TB?

Deleted.

Aren’t the cfast bus and the usbc bus independent? What leads you to believe there is a correlation?

Good Luck

Howard, that wild and crazy post of mine is now deleted! Thanks.

I'm not sure about in camera speeds. I haven't been able to get the Pyxis 12k to drop frames at constant quality Q0 12288 x 8040 @ 40fps. The Pyxis cannot record to 2 cards at once unlike the Ursa Mini 12k. Unfortunately the Ursa mini dropped frames all the time even with 2 cards.

The Pyxis 12k is an amazing camera. Brilliant images and very versatile in the way in can be rigged for different tasks. Very happy with the purchase. Just wish the EVF was cheaper.
