I’ve tried it.

I tried a portra brace sound bag harness too.

The problem is that they usually can’t go high enough !

I think BMD should make an all aluminum version of the ursas. A hollywood version. Im sure it will still be cheaper than anything else.

Cause "Hollywood" doesn't like magnesium alloy bodies?
What's the point of making it heavier with aluminum?

To give ease of mind to the producers and dps. I'm just saying a version of the camera.

My question would be whether or not the Ursa 12K is being included in the testing phase for the image it's producing (character of the sensor) regardless of the build quality in these other productions.

I'm more interested to know why it specifically works for "Lakewood" for instance subjectively for the image and if these other productions are simply defaulting to Alexa Mini because of its utility and not doing any testing with the subject material.

I felt like after watching the camera and lens from "The Great" that the final decision was a good one if not the 'right' one.

This is not the reason the camera isn't chosen more often on the kinds of projects that you think mean validation.

Every story has specific requirements.

As a DP, my role is to tell those stories with images and to determine what best services that story with the resources I'm allowed to have or able to get. It's not a simple as Arri = good image, safe choice, what producers feel good about.

And frankly, for any good cinematographer, the camera choice is a TINY small choice amongst many many other more important choices we make to arrive at a visual approach.

Just one example. Crew.

CREW makes a bigger difference. The people you choose to work with makes far greater difference to the end result than the bit of gear you shoot with. People that obsess over equipment for progressing their careers are missing the woods for the trees.

For Lakewood, we have a real time story that involves the central character running for most of the movie. She makes a series of phone calls and has to interact with her phone with maps and FaceTime etc. We never leave her side of this story. We only hear the conversations.

She starts running in urban areas, but eventually she's on dirt roads and then small tracks and then just in the woods off the track. The film plays in real time (almost).

Think about what it means logistically to film an actors performance as they run. Think about how you would do that. How do you keep the camera stable. How do you make sure what you're using to keep it stable doesn't make noise. How does it travel down a single lane winding and bumpy dirt track with branches all over the place? How do you operate that camera so the (genuine A list) actor always is in the frame... How do you make it so that the director (a living legend well into his 60's with knee problems) can watch the image when you're doing 15 min takes and the fact you're running means your "set" is a mile long... What video transmission system can you use that works over that area? How does the focus puller stay close enough to the camera to be able to make sure that everything is not only in focus but actually working and functional.

How do you even read good performance when an actor is running... How do you make is so the actor can tell the story they need to tell while exerting themselves...

How do you light and protect your one and only actor that's always running...

How do you make your visual approach so robust you never ever waste a take for technical reasons because she can only run at most, 8 miles a day. You can't make her run for 10 hours, so how do you make your system flexible enough to be able to run a second unit where you can use picture doubles?

Literally the tip of the iceberg. On one movie. Camera choice is a teeny tiny part of those problems.

*also, a very low budget film. About the same as "Festen" mentioned elsewhere here.

All camera operating is bad for your back.

It's easier than using your arms, smoother, and most of the weight is felt in your upper back and shoulders.

Blackmagic cameras are being used to make films, you just need to look around the indie scene.

Red River Road screened at Grimmfest in the UK at Easter. I asked the director what camera he shot on during the Q&A afterwards (as I thought I recognised the look) and he confirmed it was mostly shot on a P4K (with some iPhone shots).

Yeah, it's not like content shot on BM cameras doesn't do good - in fact pretty much every film I shot since 2013 (ish), that got an award, was shot on BM, except one that I shot on Red.

Listen, the only movies we should care about are the ones shot on 15-Perf 70mm IMAX Film. Just ask Christopher Nolan. And, you shouldn't be seeing them projected digitally. Go film projection or go home.

Yes I agree, but we are both wrong, as people do care and it affects the sales.

Agreed. Nothing would have a larger impact on Blackmagic camera sales (particularly in the film industry) if they were used, say on a massive Netflix $200M Matt Damon extravaganza or on next year's Oscar Winning film.

If that were to happen, it would be the talk of this forum for weeks and we all know it!

Very interesting discussion.
No way Cannes snubbed Blackmagic. The cinematographers did that.
But why?
Having worked with several cameras including Blackmagic, Red, Sony and Canon (also DSLRs and mirrorless), I have nothing against Blackmagic regarding image and post-production workflow. Blackmagic is very similar, if not better.
The only problem is reliability. You never know when your SDI or HDMI connection will conk off, when your card will stop recording, which card can shoot 3:1, which cannot, when you'll burn your motherboard because you have used the same V-mount battery to power your camera as well as your on-board monitor.
To use a Blackmagic camera the DP needs to be a geek, needs to follow each and every post in this forum, otherwise you never know...

That's too much of a trouble for any DP. That's why they pickup other cameras and shoot merrily.

I had Alexas not recording, and an SDI fried on RED - it can happen to every camera out there.

Having said that - I own 6 BM cameras, using them everywhere from the desserts of Egypt to freezing cold Canadian ice storms, and in the damp jungles of Vietnam - and nothing of all that ever happened to me. At least the BMs I own, are super reliable since years.

That’s funny. Because that has always been my impression of RED cameras and the reason why I left the RED universe. You had to wade through a massive amount of worshipping posts to get to the important information about all those little quirks, problems and hidden functions…
A friend of mine earns his livelihood as a RED troubleshooter on big sets.

While when people rent BMD cameras from me, it takes less than 15 minutes to explain everything necessary and they can work the camera. It’s not rocket science to understand why 3:1 can’t be recorded to every card there’s.

But all in all cameras and film equipment in general are still complex devices and you should bring at least some technical understanding and know-how with you.
Saying "Thx for help!" is not a crime.

These are misconceptions from folks who never owned or used a BMD camera and made assumptions from just reading the forums. Yes, there have been issues with but that's old tale and issues have happened many time on Arri and Red cameras. I've had problems even with the Helium having issues with cards - but I will say that just go with knowing first what works with the camera. A lot of the issues I know are hands down operator induced, meaning DP and Camera Operator who do not understand the technicality of the device and just treat it without care. DP and cam ops needs to be a bit of a geek... this are electronic devices folks.

Krishna Pada wrote:That's too much of a trouble for any DP. That's why they pickup other cameras and shoot merrily.

I disagree. They pickup the cameras that they are already familiar with that is why it's no longer of a trouble for them. That's a shame because as you said, Blackmagic is very similar, if not better. Only if they learn more about it and try using one.

Last time I shot on a RED, it was a music video, and when we got back to the office one of the RedCarts or whatever the SSD drives are called simply wouldn't read. This was half a Tb of data gone. Thankfully we were able to retrieve it through some command-line sorcery, but it was a sweaty couple of days trying to figure out if we were going to need to reschedule a new shoot day.

Good friend of mine shooting on the Panasonic Varicam told me that half of their footage was corrupted. This was confirmed by both the rental house and the Panasonic tech here in town...nothing they could do about it except scrap those shots or cut around the corrupted frames.

The point is that there are nightmare stories for all cameras out there. Fundamentally all modern cameras are portable computers, and every computer is susceptible to bugs and malfunctions.

On the other hand, back in the film days I heard so many instances of fogged negatives which had been accidentally exposed.

As I already posted in this thread.

viewtopic.php?f=2&t=144498#p775354

Last week I had an Alexa mini totally crap out while rolling with the screen shot posted. I lost an entire very expensive half days work shooting car to car with a stabilised car rig, police escorts, picture cars. Can't be recovered. The whole card is cactus. BMD have never done that to me.

And ha. So funny to see people's perspective on HDMI and SDI burnouts. This is happening to all cameras. In fact, if you read the outrage on REDUSER over Komodo's SDI problems, a lot of users perceive BMD has being MORE reliable and made their port's LESS likely to fry.

Yeah, and we had a SDI burnout on a brand new Canon C300iii last December. My OG URSA Mini and URSA Mini Pro G2 never had any issues with reliability. There's a misconception that any camera is more reliable than another. All cameras a prone to faults and issues. Like the old saying states: "**** happens."

Just watch next year Blackmagic Cameras make it on the list of cameras used on movies in next year's Cannes films. And, for the most part the Cannes audience won't care. All they care about is the story.

Also, remember it's the actors that make the movie.

It is so common problem that why do they not fix it on design table. How often do you hear USB C or Ethernet ports burning? There is protective circuitry available even for high speeds. Maybe it would be time for the industry to move to optical fibre...

but this gets quite far from what they are interested in Cannes Film Festivals :)

BTW, just ordered this one, cameras used to be build to last for ever and have understandable user interface.

BTW2, I had just a dead SDI on Micro studio camera, and did an open surgery for it to see if I could find something burned etc. but nothing, everything looks fine. It was not super easy camera to get into, but it looks like very well designed camera internal connectors minimised, circuitboards protected etc. good things for a reliable camera, but apparently no protection for SDI, and I have no idea what burned it. Maybe because it was wall powered during a small thunderstorm on country side, where the power lines are unprotected, open air wires for 10 km.

There is a LOT of truth to that -- one producer who hired me to shoot an indie short when she was new to producing didn't realize that Red was a brand, so she was expecting, quite literally, a camera that was red in color.

Thing is that she didn't actually care, because what she paid attention to was how other films I'd shot looked, so her only real concerns for me regarding the camera were making sure that we needed to make the camera function and to back up the footage.

And the reason that I was shooting that film with a Red is that it's what I owned; no other reason. Industry newbie in a place with no industry syndrome. :)

Ursa Mini Pro G2 has become a camera of choice for Omaze UK house raffle adverts. I'm not posting their link but you can check them out on youtube. I think it holds up very well. So Blackmagic is finding success in commercial production.

Thank you for sharing this chart. I think Blackmagic deserves a fair share in narrative production (and of course in documentary), especially in the indie space.

Don't you think Arri, RED, BMD haven't thought to do so ?

It's because WE the users want 60FPS 4K over SDI. And to make that happen it needs to be a 12G connection. And to make that happen you can't protect the circuit in the same way. A connector that has to withstand many many DAILY duty cycles (USB doesn't typically) and be used in bad weather, out doors, have the cables yanked.

Now that I think about it, 99=0% of the SSD problem threads are fixed with a new cable....

Not too difficult to comprehend....

By the way, you don know that BMD already do fiber for their cameras ?

Fiber seems a good solution, but it's got it's own baggage.

Something like this should work pretty well, actually it would probably be good idea to use that, but why not build that inside the camera. (these separately sold isolators are actually pretty expensive, but the actual isolating components likely not so)

Gee...and yet they aren't used by anyone making cameras or 12G SDI devices....

It's been discussed many times to use this type of device and my understanding is they aren't fool proof. That's why they're not implemented.

Some fun facts.

BMCC 1.5G
BMPCC 1.5G
BMPC 6G
Micro Cinema 3G
Micro Studio 6G
P4K 3G
P6K 3G
UMP front port 3G
UMP rear port 12G

The 12G driver theory does little to explain BM’s issues as only 1 output from their lineup is actually 12G.

Good Luck

The higher the speed (g) the harder it is to protect the line from ESD.

Arri aren’t 12g but have similar issues.

Yes, that is exactly what I wonder, why not. They should remove the ground loop problem as they isolate the ground.

I am not sure how this device work, but pretty sure just the same as used on Ethernet, a simple transformer. Such is not easy to burn, and if it is burned, it is "easy" to replace, also they protect somewhat the circuitry after the transformer.

Anyway this seems to be common problem on the SDI devices.

From arris paper above.

“ This is especially critical for cameras with SDI connections capable of SDI 6G or higher (even if set to work at lower bit rates like SDI 1.5G). Cameras with SDI connections capable of SDI 1.5G or SDI 3G can be protected more efficiently without decreasing the SDI signal quality.”

Common on “cinema” cameras perhaps, for the broadcast world it’s a non issue.

Which aren’t 6g/12g usually or use Fiber.

Since this has slipped into a cine saddle discussion, I just wanted to mention that in over 25 years of owning one, I never once thought to wear it. It’s been in my lap lots of times though. I’ve also never dared to tie it to a car as I’m not that great at knots. Yes it seems expensive for a canvas pillow, but it is a lifetime piece of kit.

sdi was simply a kind or RF/transmission line with usual electronics laws.

- ESD : like near all chips today, there is esd protection inside even for ancestral GS12081
datasheet : https://semtech.my.salesforce.com/sfc/p/E0000000JelG/a/440000001M10/YzgCUZ9FYZSM4bLey_Mp2hd7hkCTqI3v2bOjq9Va6ag

reliability : https://semtech.my.salesforce.com/sfc/p ... zSk27VvCnA

- Open lines, short-circuits : lines drivers are usually protected. Burning may occurs only with permanent sc.

- bad conception : RF/high speed circuits may oscillate on bad conditions (open lines, reflecting cable...). You will heard many angry consumers !

As I plan to use BMD products in a van, I just take care of some points :
- Bad earth : will use 2 isolation transformers with shield to filter noise on each provider line (10KV).
- Electrical power : replace any switching two pins power-supplies with ones having earth or with galvanic transformers.
- For stage : fiber.
