  1. Dear Sony, you can also do Hoshin planning to find a break through. Then Kaizen events can be used to brainstorm and find solutions for the next level break through. Please visit Toyota in Japan, they are the experts in LEAN.

  2. Yesterday filmed in 4K the korfball Play Off - Sports Event + 720p livestream to youtube with the "DEV" hacks to disable 30 mins limit and lens check.

    Camera NX1 proofs to be stable, even in stress conditions of the sports event! 

    • Camera: NX1
    • Lens: Canon Broadcast J17ex7.7B4
    • Record: 2160  25p on Komputerbay SD card
    • Video out: 1080P for Youtube livestream

    Great work and many thanks :-)

  3. Hi,

    One of the "issues" with the NX1 is time to convert HEVC. So using a LUT will speed up, thanks for helping the community with this. But I was thinking differently: can we get a setting out of the box, straight from camera and still have a cinematic look?

    Here are my settings:

    Settings:
    Gamma DR
    Saturation -2
    Sharpness -5
    Contrast +5     yes, it is really plus 5
    Hue 0
    Hand held

    HEVC convert with ffmpeg script:

    echo start > ff.log

    date >> ff.log

    for F in *.MP4

    do

      OUT=`echo $F | sed s/MP4/mov/ `

      ffmpeg -i $F -c:v prores_ks  -strict -2 $OUT

    done

     

    echo end >> ff.log

    date >> ff.log

    Straight from camera, no color grading, only stabilized in FCPx

    Cheers,

    Jorgen :-)

  4. Found some youtube video's showing issues with version 1.30, but I can not reproduce. My NX1 is stable so far. However I do not have any Samsung lenses, all are old MF lenses via adapter.

    Wish list:

    -Also clean HDMI out with 1080p while record in 4K internally. Now 1080p out is showing the "display". This would enable streaming to youtube in HD while record in 4K.

  5. Hi,

    If you open terminal, you can use ffmpeg for free. If you do not have a Samsung, but want to experiment with HVEC, you need to type something like this (encode to H.265):

    ffmpeg -i input.mov -c:v libx265 -preset medium -x265-params crf=28 -c:a aac -strict experimental -b:a 192k output.mp4

    More info:

    And if you have a Samsung 4K TV, it can play the H.265 files directly from USB or NAS, which is very nice.

  6. How will Canon 5D hold against 4K UltraHD Video?

    Camera: Canon 5D mk iii
    Lenses:
    •   Kowa 8z lens
    •   Canon 85mm lens
    Settings:
    • Anamorphic x2 settings: 1536x1290 24p
    • 3K cropped: 2880x1206 12p
    • 4K cropped: 3584x1320 12p
     
    The Komputerbay 64GB card does not go beyond 112 MB/s (debug mode), this is why in 4K and 3K framarate has to be lowered.
     
    Enjoy!
  7. Again, I'm confused. "85mm is what is needed" to avoid vignetting, then Vid atlantic say a 50mm lens gives 'a little' vignetting, while saying the Helios 58/2 is a good match for the 5D. So how can the Helios 58/2 be a good match for the 5D and also be the 'recommended' lens for anamorphic use with M43 format? I mean one has twice the crop factor of the other and people are recommending the same lens? I am missing something, and brains is only a small part of it.

    Hi

     

    Recently I upgraded from 50D to 5D. On a aps-c like 50D the kowa 8z works great with 50mm taking lens, no vignetting. But the same 50mm shows a lot vignetting on the 5D, because FF. So I go for 85mm on the 5D.

     

    Workflow: With ML 5D3 you can go 1600x1290 or 1536x1290 and do the processing in MLV Mystic or RawMagic. Then import DNG in Davinci resolve, set clip attributes to cinemascope in pixel aspect ratio and you're ready to go.

     

    Cheers,
