BIG URSA PROBLEMS: PINK NOISE ETC....

Jamie, your previous post mentions a VCT-14, but your video called it the VCT-U14. There is a difference.

Hi,
Steven, you are right on the record point, probably too much time in the sun yesterday and a bit of a mind blank, for those shoots yes I could run a test before hand then turn over for the entire shoot, just remember to have mains power.
Rick, yes it is a VCT-U14 and having googled it there are a couple of differences, having said that every Sony or Panasonic camera I have thrown at it didn't have a problem and the Ursa is documented as going onto an OEM plate, so maybe its doesn't like the VCT-U14? Ill check the DP's plate when I get chance and see if that is a VCT-U14.

Good stuff, Jamie. I believe the VCT-U14 should work, but I'll personally go with the Sony VCT-14 just to be sure.

Hi,
Still waiting back on a reply from the DP regarding the baseplate but the URSA went out yesterday on its second shoot. A very simple green screen shoot with PTC's. The camera behaved itself with no corruption and quick tests after each battery change gave me confidence that hopefully this workaround should halt the corruption issue, but the no battery warning is still a big worry. Surely this cannot be good for the camera to continually die of its own accord, especially mid take? I would happily run down my batteries until a warning would appear as you get the most out of the battery and also it extends the batteries life by running it right down before charging, but as soon as the battery indicator hits 20% I'm having to change over. Sometimes you don't get the opputunity to check the battery mid shot and it could just die, my worry is, is this a factor in the corruption issue, and if half way through a shot is the chance of a take being corrupt having cut through battery failure?
I know these questions have been asked previously but felt it was relevant as the topic was fresh, this also brings me to sound delay which was more prevalent yesterday when in such confined area.

Hopefully the new firmware will address these issues asap.

Does anyone know if BMD is attempting to implement a low battery warning as mentioned above? I could see this being hotly requested for the 4K/4.6K mini

You shouldn't take LiPo batteries down much past 20-10% anyway, they do not have the issues that NiCads did when not completely discharged.

I agree, but I still think a warning feature is required.

The Ursa mini 4k has it and it's coming for big brother in a firmware update.

Weird. But, I heard the VCT-U14 is not recommended for URSA. Says so in the manual.

As for the battery warning, I'm pretty sure Hook said that you'd be able to monitor your batteries in the viewfinder or monitor by percentage or voltage, depending on what you want to do or the limitations of the battery and camera talking to each other.

Hi Jamie

My URSA cameras sometimes produce pink noise error, but only if I use a CFAST 2.0 (approved) card.

If I use Samsung 840 EVO, 850 SSD (512, 1TB, normal mode, or dual card mode), the pink noise error never happened.

Stupid looks with two SSD, but it works without problems. (200+ hours dual mode RAW 80 fps recording)

Correct, it will work with the lighter Ursa Mini, which is closer In size and weight to the DSR300 series that the VCTU 14 plate was designed for. The big Ursa, needs the heavy duty VCT-14, designed for the larger 2/3rds ENG Betacam cameras.

Also, a low battery warning light or indicator is a good idea, somethings to grasp the camera ops attention, even a flashing monitor screen, or flashing Tally red line around the monitor image, steady red when recording, and flashing red when their is an error, or low battery situation.

What firmware are you using? This shouldn't happen if you're running the latest firmware.

Hi Captain

The 2.3 firmwares were problematic mainly. Indeed they not have done in the 2.7 firmware.
However, the 2.7 firmware is not used CFAST card, only a couple of times (there was not a problem at this time), primarily 2x1TB SSD necessary because of the long shots, mainly nature film RAW 3:1 80fps, to this use CFAST card yet very expensive

Sorry my bad english

Thanks:

So you're using something that's not recommend on the camera at all and think you have a problem yet you say you don't have the problem when you use what's recommended? Is it just me and I'm taking crazy pills here?

Or is that backwards and why are you using SSDs?

Excuse me, may be badly I composed.

There is no perfect camera. Yes, there were problems but I think it is caused by the rudimentary CFAST cards. I've never had problems by using SSDs, not even with the previus firmware versions. I use SSD, because the cost of 2TB SSD storage space equals the cost of 256 GB CFAST card storage space.

Ferenc, I think Vic was trying to say, it is your setup/adapter to use SSDs instead of the recommended CFast cards the camera was designed to use, that is causing your pink noise issue, not the camera itself.
How are you recording to SSDs, with an external SSD recorder like a Atomos Unit,more some type of adapter cable connected to the CFast card slot?

I use junk chinese CFAST DATA Breakout Cable connect to the URSA CFAST slot, and a little 12V to 5V DC/DC unit, connect to the D-Tap 12V output of V-mount Battery.

The Atomos Unit, for me is not an option as there is no RAW. I really like the URSA 3:1 RAW option.

Then your problem lies with the cheap Chinese Junk adapter! Get CFast cards, you will get rid of the "pink noise". Cheers.

Excuse me wrong my English, maybe badly I explained...

I saw the pink noise only a couple of times, but only I had a problem with CFAST card. (2.3 firmware+SanDisk CFAST 2.0 Card)
The SSD+(junk adapter) pink noise problem never came forward.

Sorry, I did misunderstand. Hope the problem does not show up again. Cheers

SanDisk cards are no longer supported as there were a number of issues with compatibility. (They've been pulled for quite a while now)
Try the updated firmware (2.7 as you have mentioned) with some supported cards from either Transcend, Lexar or Wise and see if the issue is still there with CFast cards rather than SSDs

Boom.

Knowledge and research are power!

Or blame the camera

Actually if you read back he was referring to firmwares working and not working so yes, that's part of the camera. Also I've seen countless threads on both forums about this exact same thing and dropped frames from people using the wrong card and blaming the camera. Same exact thing, same exact problem.
