  1. "I think what he is saying is Panasonic actually finishes their low end products before pushing out newer high end products."

    --------------------------------------------------------------

    I always thought this place was for the artist? The guy who will jump through hoops to get a beautiful image? The guy who will use a $200 Nikon to get a taste for 4K/Raw/60p?

     

    Now, all of a sudden, a couple of firmware glitches (that I also want fixed, but don't live or die by) coupled with the news of them pushing on with a new camera and they are "turning their back on the indie community"?

     

    In a perfect world, my £650 cinema camera would show me how much SD card I have left, but I just work out my GB per minute and guesstimate, erring on the cautious.

     

    As long as BM keeping giving me huge bangs for bucks, they'll keep getting my bucks... A bit of firmware angst and some new cameras wont change that. They are still firmly the great shining light of the indie community.

     

    In a perfect world? How about in the REAL world. We are talking basic functionality. Stuff that can kill you on a shoot and end up losing you your job. If you have a mega expensive unrepeatable shot ready to roll and the camera just cuts in the middle because the card is full without warning, I'd love for you to come back on the EOSHD forum and sing the praises of your £650 cinema camera.

  2. spec wise it ticks all the boxes

    super 35mm size sensor 4k and global shutter in a usable body form like an Alexa -

    what more do you want

    Blackmagic have listened to all the feedback off their other 3 cameras

     

    indie film makers will jump all over this - superb!!

     

    I honestly don't see it this way mate.

     

    Trend is to go smaller and lighter.

     

    This goes in complete opposite direction.

     

    We already have the same 4K capabilities and likely even same sensor in the Production Camera. Rig a monitor up to that and you have Ursa without the bulk.

     

    Also those ProRes HQ 4K files are virtually unmanageable when it comes to archiving footage. Be prepared to delete and compress a lot of master files if working with those. I am already dreading it with the A7S... And will be begging all the recorder manufacturers to come out with some lighter codecs for it.

     

    The URSA doesn't suit me as a filmmaker but that's not to say I haven't considered the possibilities and who it WOULD suit.

     

    I just don't think it's well conceptualised or designed to be honest. A massive heavy screen on a little hinge? A 7.5kg camera body? No thank you.
     

    It smacks of greed to go after the production market before you have even satisfied the indie crowd... who are constantly asking for basic features and updates.

     

    I'm afraid I don't be shooting any Blackmagic in 2014. What a shame.

  3. recording

    Blackmagic are launching not none, not one but TWO new cameras at NAB 2014. One as you can see packs quite a punch with a quite revolutionary design. The aim of the URSA is to take all the accessories you'd normally rig onto a Blackmagic Cinema Camera and integrate them. That is a sensible idea. However the execution looks to have produced a 7.5KG monster. There's even an HDMI version of the URSA which has no sensor block or lens mount but a cradle on the front for any camera with HDMI output, such as the tiny Sony A7R. That would give you a full frame 4K URSA recording to CFast cards.

    However the URSA is aimed at a large crew, large scale productions and in doing so completely turns its back on Blackmagic's existing indie filmmaking user base.

    To make matters worse Blackmagic show no sign of any significant firmware update for the 3 existing cameras at NAB, which is what people REALLY wanted them to announce.

  4. I can guarantee that the internal XAVC-S 1080p from the A7S will not look as good as getting 1080p from the 4K output and doing your scaling in post with all that processing power available on your desktop.

     

    8bit 4K 4:2:0 = 10bit 1080p 4444 remember. If the maths have complications and gotchas, the image to my eyes does not. The GH4's 4K looks like 10bit when you grade it and when you look at it on a 2K display. Gradations are smooth. Colour is fantastic. Sampling shows no signs of pixilation or jaggedness at 2K. At 1:1 at 4K you do see some aliasing and jaggies from 4:2:0 sampling. They disappear when scaled correctly to 1080p or 2K.

  5. Raw or ProRes / Pocket Camera vs GH4 and A7S 4K is definitely a topic for a future blog post.

     

    My feeling so far (based on the GH4) is that this compressed 8bit 4K stuff makes for very nice 2K and 1080p indeed, which looks every bit as good colour and dynamic range wise as the Blackmagics or raw on 5D Mark III.

     

    Also GH4 in 4K has far less moire & aliasing than the Pocket Cinema Camera and BMCC, especially when downscaled to 2K.

  6. Spec sheet says 8-bit. It's quite easy to feed 8-bit acquisition into 10-bit ProRes, which is probably the case here.

     

    Den or the Sony spec sheet? Who is right?

     

    3840 × 2160(30p/24p) / 1920 × 1080(60p/24p) / 1920 × 1080(60i),YCbCr 4:2:2 8bit/ RGB 8bit

  7. I've seen some people tossing around the notion that lower total pixel count (and the implied greater pixel pitch) doesn't necessarily improve low light performance. Is this true, or potentially true (not necessarily for this camera, but in general)? 

     

    For video it definitely does.

     

    For stills, depends on print size. 36MP loses some low light performance but the oversampling makes up for it. Like going 4k to 1080p.

     

    Other thing that matters is the pixel design, micro lenses and gaps between pixels. For example Blackmagic Production Camera has only 8MP but tiny pixels because most of the space on the sensor is taken up by global shutter circuitry.
