    If you are reasonably sure you don't have a GPU issue, check your RAM (MemTest86 should do).

    All the other Canon cinema cameras use log raw. Very unlikely to change this now.

    Not really.
    4K ProRes 444 has significantly larger data rate than Canon's 1gbps raw. Around 40% more (assuming 30 fps). Once there is native support for the format in Resolve and other apps, there...

    Avid lost 3/4 of their market cap in the last 2 years (and managed to do it in a rising market). In the meantime, Adobe quadrupled in the last 5 years and are now worth 300 times more than Avid. It...

    With a good CPU (hexcore or better) and fast storage you can probably do fine by using low res timeline (i.e. 1080p) and a low res debayer in Resolve (i.e. half or quarter resolution debayer). You...

    slimRAW 1.8 is now up on the site. It adds 7:1 compression, which will yield data sizes around 25% smaller than 5:1.

    Mainly targeting resolutions beyond 4K (Mini 4.6K, DJI X5S; possibly the...

    Pretty sure Resolve doesn't debayer Arri material using the Arri SDK. Or at least it didn't in the past, been a while since I last played with it.

    Tokina 21mp C-mount machine vision lenses

    There is a fairly new series of 21 megapixel 1" machine vision C-mount lenses by Tokina. The set has 12mm, 16mm, 20mm, 25mm and 35mm.

    They are apparently very sharp (resolution up to 2.4 micron)....
  10. This is a bit optimistic in the sense that you...

    This is a bit optimistic in the sense that you actually almost never get data straight from the sensor. Maybe with the Bolex, but in general there is lots of processing before saving a "raw" file. In...

    It is not a "true" bitdepth in the sense that initial quantization has happened with lower precision. It certainly is more color information after downscale than the starting bitdepth can carry...

    Well, it is dead anyway. :)


    It can, see my edited post above.

    Here are a few clarifications:
    Chroma subsampling is a concept which does not apply to raw images. "4:4:4" 12-bit is a meaningless statement for raw.
    The Bolex can do 25 fps (not shutter angle...

    There is zero difference between uncompressed and losslessly compressed. "Zero difference" is not the same as "virtually no difference". Zero difference means no difference whatsoever after the...

    Weird, it is a standard PNG image, a format used all over the intermet. The default Windows picture viewer should open it fine (or any browser you have on your computer, for that matter). I've...

    Well, here is a Mini46 raw frame (courtesy of John Brawley) compressed at 8:1 (this is approx. the data size of a lossless Pocket frame). I've also included a 1080p .png frame exported from Resolve...

    Not sure why you can't be convinced, because there is no magic involved, neither rocket science, so there is no need to be mystical about this. If the files contain approximately the same amount of...

    You can compress 4.6K raw down to a size similar to the Pocket and it will look as good when delivered at 1080p. Actually it will look better, cause there will be much less aliasing.

    Thanks.
    Which camera are you using? If it is the Production4K (huge files? :) ), it also works very well with the higher compression levels. It has a really fat image, so lots of leeway for...

    You should be looking at Resolve for real time raw editing. Premiere works but is lacking in performance.
    Also, there are no 4K BM cameras recording raw on SD cards. Only Pocket and Micro record on...

    Evaluating raw DR using 4:1 is probably a mistake. He should have used lossless raw. The way BM does lossy raw compression shaves off a bit of DR.
