Larger sensor is going to have more problem with rolling shutter. The solution should be develop sensors with global shutter.  Sacrifice some of the sensitivity in exchange for solving this problem.  

 

I don't think it's so much the physical sensor size as the amount of data to read off it. 4K is a lot of pixels. 2160 lines is double the number to scan than 1080. It takes twice as long, so to compensate you have to speed up the rolling shutter. Sony have not done this enough.

Thanks for the post, I have promoted it to the front page and given it it's own thread '?do=embed' frameborder='0' data-embedContent>>

That's not rolling, that's twisting.  They outta see if Chubby Checker music is available for the tv commercials. 

 

If Chubby isn't available about Den Lennie? :)

Oh dear. :D At least it can see in the dark.

 

There goes my dreams of ghost hunting with this camera. Going to be a lot of leaning Slimers in the frame.

 

>Here's a test from the EOSHD forum which shows me what I was a bit afraid of. The A7S looks to have similarly extreme rolling shutter to the AX100, at least in the early pre-production firmware stages.

Yes raw. How about we do some more experiments then?

 

It is worth figuring out the best way to manage our SSDs.

 

Although thankfully I won't have this headache any more with compressed 4K on the GH4.

I think it depends on consumer expectations. Maybe people are used to firmware updates now and expect a constant stream of upgrades for free.

 

With Blackmagic that should have happened, no doubt about it, because for one thing it has been promised and for another, the cameras lacked basic features.

 

The GH3 has a ton of features and Panasonic haven't promised anything.

 

My firm advise is to upgrade! I don't say this out of any interest of Panasonic getting more sales off the back of my free publicity. I say this as one filmmaker to another. Do it.

Sony A7 what again? :)

I just got banned from BMCUser, so can't defend myself against what people are saying on this thread -

In light of the email and what I have explained, would any EOSHD supporter be brave enough to step in here and tell the truth?

 

I'd be eternally grateful for it!

Also the highly anticipated Sigma 50mm F1.4 DG HSM ART now has a price - this will be an exceptional piece of glass to use on the GH4 with Speed Booster pre-order the Nikon mount version at B&H for $995 or the Canon mount version

This shot by EOSHD forum member Julian confirms that Panasonic have now completed the final production firmware for the GH4 (version 1.0). The unit pictured above was loaned to Julian but it is a good sign the camera will be shipping on time from stores - possibly by the end of this month in less than 2 weeks.

Version 1.0? Very nice.

Bit cheeky if you ask me.  Grab the early adopters kit, take away the two most important components of the setup (the diopters), add a huge markup, stir it up and you have a fine anamorphic mess.

 

I agree with Rich here.

 

But it takes two to drive up prices... a buyer and a seller.

 

How about buyers exercise a bit more restraint as well...

 

To avoid further arguing I'm locking the thread.

Amazing - like turning night into day - unfortunately the day part just looks like a normal cloudy day with bad light :)

 

Anyone else think this is an absurd way of presenting a test anyway?

 

It's so compressed that ISO 1600 looks noisier and blockier than ISO 25600.

 

Cannot get a proper impression of anything from YouTube.

 

This is why I put my camera tests on Vimeo instead.

 

Get the original file up somewhere!

I don't feel abandoned by a new release but I do think the panasonic GH3 has still a few bugs which they should repair. I'm just afraid they won't concentrate anymore on solving these because of the early release of the GH4. Bye the way I turned off my eye sensor and still the monitor tends to shut off in a certain angle.

 

The monitor issue sounds like a hardware problem and perhaps you should return the unit to the store.

 

As for firmware some of the features like peaking aren't supported by the hardware so cannot be implemented.

 

Panasonic still have an incentive to support the GH3 and they don't stop updating firmware just because the new one has been released.

 

My advice is even if you don't need 4K resolution, 4K makes for much better 1080p so maybe time to upgrade if you are a GH3 user. For the price the GH4 gives you much more bang for buck.

No, I mean that it's a design oversight. I understand that as they had the cameras working before release, the ability to format/delete media might have caused fragmentation. But to then just say, "okay, forget it!"? That's pretty crazy.

 

I don't understand it either, I very rarely format my SSDs and usually delete the clips, sometimes individual ones, before putting the media back in the Blackmagic and it records just fine. Yes fragmentation does hit performance but does it really hit it to such a degree to impact a shoot? I've not see that. Are write speeds really so close to the limits of the drive for this even to be an issue? You just have to take Blackmagic's word for it that this is the case. I am sure on faster media with write speeds in excess of 550Mb/s even with a fragmented file system a continuous chunk of data should still be able to written at fast enough speeds to support 2K raw. Also on SDs and CFs with the Pocket camera and 5D Mark III in raw I have not had fragmentation impact any of my recordings yet.

Thanks for the clarification Andrew. As i said it did seem pretty suspect to present the article in such a way.

 

Why don't you trust me after 3 years of giving you solid info and news for free?

GH3 firmware discussion is completely off topic. Deleted. If you want to discuss that then feel free to open a new thread.

Yes, i'm talking about the Cinema Camera not the Pocket, because the last year they announced a Active M4/3 mount on the Cinema Camera but this has been banished on the time; to me was the perfect version for this camera i never understand why they release this camera with a passive mount and few moths later release the Pocket with the Active one.

 

It is likely that the unified firmware is needed first before that can happen. No point modding the hardware when the firmware to support active mount on the 2.5K isn't ready yet.

Here is the proof.

 

 

Maybe I should not be so vocal about defending the interests of people who, in fact, absolutely hate my guts like a small minority of Blackmagic forum users.

Dude as 2 posters have pointed out.. This news was already posted to the official forums long before. By Kristian himself. Why are you literally copy and pasting his words and representing it as an interview you did? Did you actually interview him? Seems extremely suspect. Im hoping for your sake you did actually interview him.

 

Seems I need to clear up some bullshit with a big broom... yet again after leaping to the defence of Blackmagic.

 

I wonder why I am not on a beach somewhere and instead bothering to provide a free source of info about their cameras.

 

First off.... Kristian posted the update yesterday not 2-3 days ago as Olly P suggested.

 

http://forum.blackmagicdesign.com/viewtopic.php?f=2&t=21179

 

Look at the date and time stamp.

 

I believe Olly has in mind the very first update about the 4 fixes in the firmware, none of the other details were in that first update last week.

 

I did not report on that first update like nofilmschool - instead I pushed Blackmagic for more details by email all during NAB because I wasn't satisfied that the original update had enough info in it.

 

This discussion by email with Blackmagic started a few hours after the new camera announcements at NAB. Yesterday the reply this article was based on came to me as a personal reply from Patrick at Blackmagic directly, fitting like a glove to all the points I'd raised.

 

I am not trying to take credit for anything I didn't initiate... that's the way it happened and there were other emails following up to it. I am putting the info I had in the email out there. I'm not cutting and pasting it from their forum. To hear some people speak about me with minimal respect is very saddening. To hear them you'd think I was a PR hungry prick grandstanding like Tony Abbott tweeting pictures of himself on the phone to air force commanders or something.

 

I had not seen that they'd also posted it on their forum. I don't follow nofilmschool either. I really don't care who should take the credit for the update or whether Patrick was emailing me a cut and paste job.

 

Important thing is I got put the info in your hands and it came to me direct from the source.

"The admin" haha as if like there's anybody else here. Amusing. I'll call the guys behind EOSHD and ask them if they can change my title from admin to filmmaker.

If the blackmagic production camera does get all the things they said it would, how would you compare it to the gh4. The gh4 has a more complete package but if they actually update them how far closer would it close the gap?

 

I loved the image from the Production Camera, though it was limiting to have ISO 400 native and the fixed pattern noise above that when the image is lifted.

 

For my kind of work, the form factor of the Production Camera isn't as suitable as the GH4, because it's just a sensor in a box. It really needed a lot of extra bits adding, which is why Blackmagic noticed everyone rigging their Pocket and Cinema cameras up, and responded by bringing out the URSA.

 

I don't need to rig up the GH4. It already has everything I need built in. I really cannot be bothered with rigging stuff up crazily. Gets in the way.

 

I also prefer the lens mount to the EF mount on the Production Camera. More versatile. The smaller sensor doesn't bother me because when I want the Super 35mm look, I get it out of my bag and attach it. Speed Booster.

The a7s looks more cinematic to my eye and the gh4 more video camera, either byproduct of m43 or panasonic codec.  What is everyone's thoughts on that?

 

Though a bit of a sidestep...how do you all feel about the 4k footage in these cameras compared to 5d3 Raw?

 

Tell us why you think the A7S looks more cinematic then we'll address the specifics, A7S vs GH4 ok?

We are a sensible bunch here, I don't think we need patronising with warnings not to 'get caught up in hype' and I certainly don't think you should be calling my positive evaluations of a camera 'hype' either!

By studio camera do you actually mean Cinema Camera (2.5K)?
