    GXAlan got a reaction from CMCFirm in Samsung NX Speed Booster   
    I am going to be exiting out of the NX system and was Backer #1 for the Nxl.  If anyone is interested, let me know before I start posting it on the usual for sale forums.  I am based in the USA.

    GXAlan got a reaction from Marco Tecno in Samsung NX1 Firmware 1.20 Coming Soon   
    Wow!   There are a few other things which would be really cool.
    1) Allow peaking to be "ON/OFF/Always" so that we get peaking without zooming in (Sony style)
    2) For the intervalometer, allow extended exposures beyond 30 sec for astrophotography.  Arbitrary is best.  But 60 / 90 / 120 / 180 / 240 / 300 sec would be golden

    GXAlan got a reaction from Flynn in Samsung NX1 vs Canon C300   

    It's not just Premiere.  Transcoding into ProRes can cause that problem too.  #1 challenge with the NX1 is workflow.  The price/performance makes it a worthwhile effort.  TBH, the NX500 is going to be the better deal for 4K/UHD 24p

    Ok, exporting the HEVC to TIFF directly, skipping the ProRes. 
    1) All channels DO show 0-65535 range.  So ProRes is making it worse.
    2) The flicker is visible on source HEVC as well.  Here are the median values L/R/G/B (i'm skipping the standard deviation)
     
    TIFF   A 48059 / 44461 / 46260 / 47545
    ProRz A 48059 / 44718 / 46517 / 47545  
    TIFF   B 48059 / 44461 / 46260 / 47545
    ProRz B 48059 / 44718 / 46517 / 47545
    (overall brightness is the same, but it is slightly higher on ProRes.  Would be one tick in 8-bit 0-255 scale)
     
    TIFF   C 47288 / 43690 / 45489 / 46774 
    ProRz C 47288 / 43497 / 45746 / 47031
    TIFF   D 47288 / 43690 / 45489 / 46744
    ProRz D 47288 / 43974 / 45746 / 47031
    So compared to ProRes, the overall brightness drops the same 1.18%.  However compared the ProRes is a bit brighter in green/blue and darker in red.
    I compared the frames and then did an stretched the histogram.
     
    So there you go.
