Who wants to shoot 422 10bit 1080 50p Green Screen footage with your Panasonic GH4 ?

Categories: Media 4 Comments


Just 2 days till we get our GH4/YAGH and already its apparent there is no way to produce 10bit 422 Full HD footage to an external recorder…its a joke. Thanks to Panasonic we only get 10bit 422 via the HDMI or the SDI output of the YAGH, this is a nonsense and has crippled the GH4 for recording green screen shots straight from the camera onto the internal SDXC card.

Your only option is an external recorder but sadly there is no suitably priced external recorder on the market that allows 1080 50p footage.


Atomos does not produce a 1080 50p external recorder till the end of 2014..the £1500+ Shogun which uses very expensive CFast media, even the SDI “BLADE” only produces 1080 25p footage. Reading further Atomos are looking to have the Shogun shipping during IBC in September but I hope their prediction of having CFast cards at consumer price levels is correct.


The Odyssey by Convergent design is promoted as a “monitor only” at £2000…Here is the info from CVP’s web site “Out-of-the-box, Odyssey7 & Odyssey7Q products are monitors only, without any recording or playback capabilities. Recording options must be purchased (or rented) separately from the Convergent Design website, available 24/7, via a secure credit-card transaction. A wide range of recording options will be available, including compressed, uncompressed and various flavors of RAW.”



This is the Sony option, to be fair you will always need to buy your SSD on top of your external recorder but a further $795 for the convenience of making the “MONITOR” into a “RECORDER”…I think this will all change when ATOMOS bring out the Shogun.


The AJA Ki Pro mini at £1600 is limited to 1080 25p


Lastly the Blackmagic Hyper Deck shuttle at an amazing price of £255 is once again handicapped by a 1080 25p HD Format.

It seems to me that you only get 1080 50p with 4K models rather than the companies producing a Full HD recorder that gives you 24, 25 and 50p.

If I have missed a reasonably priced external recorder that records 10bit 422 1080 50p please let me know.

    I’m not purchasing GH4 until this problem is resolved. I do lots of green screen work and 4.2.0 sucks.

    Kudos to Atomos for taken the first step in solving this problem. The establishment companies have no desire to give us a reasonable price solution.

    HDW : The Australians have become big players in the video industry upsetting some major players in the last couple of years.

    There is an argument floating around that internally recorded 4K 4.2.0 material on the GH4 has enough colour information to create (through a transcoding application)- 10 bit 1080p 4.4.4 or 1080p 4.2.2 files.
    This theory has apparently been proven -http://www.eoshd.com/content/12594/exclusive-first-app-resample-panasonic-gh4-4k-8bit-10bit-444

    Why oh why is anyone concerned with 4:2:2 10 bit at 50p???
    As long as you can record 4:2:2 10 bit at 25p you’re sorted!
    50p will give you almost zero quality difference and is really only ideally for fast moving action shots, which most greenscreen shooting is not!
    Do let us know what advantage (if any) there is shooting greenscreen at 50 as opposed to 25p?

    HDW : Firstly IT LOOKS BETTER secondly filming in 25p all your moving shots are staccato, sport/fast action looks terrible shot at 25p and filming at 50p looks far more natural and converts fine to 25p for the internet. Quality is my aim and 50p is double the amount of frames for a start and is far superior for graphics…my DVDs look far better filmed at 720 50p. Its also a cost issue, it takes far more card space to produce 50p than it does 25p which is why lower cost productions prefer 25p.
    It’s a look…some people like 25p for the “cinematic” blur, I don’t care for it…my “look” is 50p its a personal choice and my clients like it as well.

  4. The Atomos Shogun captures to standard 2.5 HDD or SSD disks. The CFast option is just an option.. not compulsory. The HDD or SSD are raided to get the performance required for 4K 10bit 422.
