    alanbraken reacted to maxotics in RAW Video of What Sensor Sees   
    Half the things I try with RAW end up no-where--just can't figure it out.  Then one day it clicks.  Last night I was finally able to create a video that shows the bayer pattern recorded in RAW, before debayering.  I hope to do more in the future. 
     
    I wish I had seen a video like this early on, so I would have visually grasped the importance of what de-bayering algorithm is used.  Also, would see why one dead sensor pixel is insignificant.

    First shot with Lomo fisheye for mtf. Did someone else buy this kit? What do you think? Rip off or awesome toy?

    alanbraken reacted to Andrew Reid in On Test - First Impressions - Sony Rx10 And A7R   
    More than any camera that came before it even from Sony themselves, the A7R marks the end of the DSLR era and a transition to a future. Next to this camera the Canon 5D Mark III looks, feels and performs like the dinosaur it is.

    However it's the Sony RX10 that is arguably the most capable from a video perspective.

    Above - the compressed 2.4k version of 4K raw from the Nikon V1 by Javier Sobremazas

    There's a dark horse in our midst which very few know about, a camera which can shoot 4K raw at 60fps for $200.

    Not a huge amount of discussion on gear/techniques used to record audio on this forum, though its not totally neglected.
     
    I have a background in classical music recording, and am used to a laptop audio interface rig with great preamps and nice mics. Needless to say, I'm not happy with the preamp on the H4N and the rode videomic type shotguns. 
     
    Anyone have any experience with the Roland R26? I've heard good things, but is the noise floor really lower than something like a zoom? If so I'd be interested in picking one up. If not, I feel like I'm going to need to invest in something like a sound devices mix pre to feed my NTG2 and NT4

    I guys i been going through my huge collection of videos that i keep for inspiration came across this video shoot on 60d and 35mm and 100mm lens that always inspire me to be better. I know raw is cool right now but i believe no about of raw and cc can replace bad story line or video that was shoot bad you know cam movement and framing. I have my black magic 2.5k still in he box not open, wont open it until i do few more project with 60d,

    alanbraken reacted to Julian in Blackmagic Pocket Cinema Camera c-mount lens compatibility list   
    Eagerly awaiting your Pocket Cinema Camera? You already have a micro for thirds camera and some C-mount lenses? Want to know if they will cover the sensor of the Pocket? Lets find out! I hope you will add your results, so we can make this list growing.
     
    I will only add lenses to the lists when you have proof, in other words: images.
     
    How?

    Because we know the active sensor area of the BMPCC measures 12,48 x 7,02 mm, it is fairly easy to check if our C-mount lenses will cover the full sensor. Calculate this by taking a picture with a lens on your micro four thirds camera, and crop out the image area of theBMPCC.
     


    In Photoshop:
    Open the image. Go to Edit > Image Size, uncheck resample image. Change Image width to 19 centimeters, press ok Go to Image > Canvas Size, change dimensions to 12,48 x 7,02cm, press OK to crop the image to BMPCC size. Resize to 1920x1080 pixels Post your results! Note: If you shoot on the GH3 or other MFT camera's, the sensor size is 17 x 13mm, so change the width in step 3 to 17 cm!

    To lazy to do it yourself or you can't work it out? Upload the full resolution files and I'll do it.

    List terms explained:

    Yes = covers the full sensor of the Blackmagic Pocket Cinema Camera
    No = doesn't cover the sensor
    Needs modification = Doesn't fit on C-mount to M43-adapter without modifications
    Equivalent = The focal length and depth equivalent on a fullframe camera (5D Mark III for example)
