    In fact, is there a special advantage in 3-sensor cameras? Considering that with the advancement of sensors, the difference has become imperceptible.
    All single sensor CMOS cameras need their images to be Demosaiced. Three sensor cameras don't as they have a full complement of R, G & B pixels on each sensor. Most single sensors have 50% green photosites, and 25% red and blue, respectively. In the process of Debayering the missing 50% of green and the missing 75% from the red and blue channels has to be reconstructed from an algorithm. Depending on the algorithm, it is generally accepted by sensor designers that this process involves around about a 20%-25% loss in resolution. Example, most 4K photosite cameras really only have a resolution of 3K plus, not 4K. One of the exceptions to this rule of thumb was the sensor in the Sony F65. A 4K camera but with an 8K sesor. Good sensor info found at the last link below.


    Sigma have tried for years to develop their three layer RGB Foveon sensor to a degree where it can compete favorably with single sensor Bayor sensors. So far not too much luck. Three sensor cameras are inherently more sensitive, given that you are comparing sensors of the same size. See links below.

    Hello Mr Young;

    You mentioned - debayer- in one of your posts, (of course it's from years ago) do you think this method have compatible enough with 3_chip processing?
    In fact, is there a special advantage in 3-sensor cameras? Considering that with the advancement of sensors, the difference has become imperceptible.

    And another question about the first generation bmpcc small camera (with a one-inch sensor), do you think this camera used a bayer filter, or a three-layer filter technology? I will be very happy to hear your opinions in any case

    I also invite you, if possible, to join our post, comparing two Sony cameras.

    Thank you

    Hey Doug. Only just seen your reply. Actually, I did find it and used it. Many thanks... half a year late!

    found this video for low light XF705 vs Z280. You see clearly the canon needs lots of gain to match the brightness of the sony. That's my conclusion

    Hey Chris, good news.
    This morning I got to wondering if Story Blocks kept a record in my account history of what I have downloaded. So I looked around, and there is it was. I had no idea. Anyway, I knew for sure what month that Z280 video was edited so it was easy enough to zero in on the track with a few clicks. Its called "Miles Above". I hope it works for your project.

    Thanks for the heads up DJ. I'll try Audio Blocks. Not critical but is sounded like a piece that would suit a job in hand.

    Hi Chris, I edited that video more than a year ago and I can't recall where the music came from. Hell, let's be honest, even if I edited it last week I probably couldn't remember. I'd say there is a 80% chance it came from Audio Blocks, but I couldn't say for sure or what the song is called. I'd call up the Premiere file and have a look but I'm on a two-month road trip and that computer and drives are all back at my studio. Ask me again in mid-October and I'll be happy to look it up and tell you exactly what it is and where it came from.

    Well, you can't go wrong with an FX9, but it is kind of funny that you were looking at the Z280 and then ended buying a FX9. It's kind of like looking at a wrench and then deciding to buy a screwdriver. Totally different cameras.

I wanted to upload an entire XDROOT older intact so you'd have all the support files and could read the metadata etc., but Drop Box won't let me send nested folders so you're only going to get the .MXF files. I hope it works for you. It really goes against my grain to pull the video files out of the nested Sony structure.
    Thanks you sir! Much appreciated.

    Really nice exposures, compositions and operation in that Myakka video above. Looks like a fruitful weekend! Sometimes the greens are very rich, but I imagine that was true in reality?

    Fhammond - as for H.265 aversion, why not employ a proxy workflow? I switched back from Adobe to FCPX last year because I had issues with Premiere's reliability, and I love the straightforward proxy workflow in FCPX. I no longer give a thought to my capture codec.
