    dxotic reacted to Sage in GH5 to Alexa Conversion   
    @tihon84 V1, especially Daylight, is not bad. V1 Day with VLog in Resolve is quite good. Notably, the Emotive Color component is quite different in exposure handling (which is apart from LogC accuracy). Emotion II is especially egregious, because it features pre-release GHa (pre-Blue and other updates), and the original 8bit PRE, with a hasty midnight grade. I knew (and noted then) that it was a poor technical showcase, but something that I wanted to make for some time
    That being said, V1 did have an important flaw (apart from the limitations of that process). That flaw was related to the fact that I did not own the Alexa, and had a single window to get the measurements right. I opted to use different lenses, which I thought would be sufficiently neutral. I didn't get a PL adapter for the GH5, and only realized that this would be a problem upon reviewing the results of the shoot. It turned out that Zeiss CP.2s are quite poor in color rendition, but my Sigma 18-35 was excellent. So, I neutralized the grayscale white balance... a kind of continuous white balance shift throughout the grayscale, to accommodate the difference
    Subsequently, I bought an Alexa (really), to make it perfect. This has proved vital, because I have redone the measurements countless times now, tweaking and tweaking again (same lenses all the way). V2 is approaching the theoretical 'perfect conversion' because of this, and because of the new process, which features 25 times the number of samples, and the code I wrote to handle that unwieldy sample count to a new standard of accuracy and smoothness (previously out of reach with the given degree of intricate transform)

    The path recommended for utmost fidelity is:
    VLog in Resolve
    Those using HLG in Premiere (for example) will not be at a major loss - the difference from that optimal condition is slightly less rolloff accuracy and slightly less smooth. 
    For 4k 60p Vlog in Resolve, no PRE will be needed (likewise 10 bit VLog, except ProRes). Subsequent paths in order of fidelity:
    VLog (10bit) in Premiere
    VLog (8bit) in Premiere
    HLG in Resolve
    *** in Resolve
    HLG in Premiere
    *** in Premiere
    In Premiere, avoid the Luma curve of Lumetri. Rather use the lift/gamma/gain wheels, or RGB curves (in Obsolete)

    Hey @Rikoshet
    You'll only need one instance of Lumetri - the 'Basic Correction' section can accept the [PRE] technical conversions, and the 'Creative' section can accept the GHa conversions. Then, in the Basic Correction section, any needed white balance adjustment may be made, which will stack inbetween the [PRE] and GHa conversions.
    You may then right click on Lumetri, and 'Save Preset' for use later (w/ a title like "8-bit Daylight (Soft)", etc.) This will save the step of having to load two separate files. A lumetri effect may be copied and pasted to multiple clips, and an 'Adjustment Layer' can be stretched over several clips in Premiere to apply a single instance of Lumetri to all underneath it for a one-light grade.
    I'm about to revisit the PDF. A lot is about to change.
    I've been revisiting the 8-bit Emotion II, updating it to the new color science:

    Hi Sage,
    Will you be offering the GH5s conversion as a free update? I have the GH5 but may sell it to get the GH5s as it would suit my needs more. But I want to get into shooting something as it looks great and also test it out.
    Will the color coded engine be an app that you input the Kelvin into to get the lut? 
    Sounds intriguing!

    dxotic reacted to hyalinejim in New log profile for Magic Lantern RAW   
    Danne (Magic Lantern superstar) and I have been working on a log DCP profile for Magic Lantern. At the moment, it's just for the 5D3. But if feedback is positive we will try to roll it out for all Magic Lantern cams.
    This profile is for use with an Adobe Camera Raw to After Effects workflow (although it may have other applications). Although other workflows may be faster - Resolve, for example - many people feel that the debayering, colour reproduction and noise control offered by ACR is unparalleled.
    The philosophy with this profile is to get the raw linear data into a log curve, so that blacks and whites aren't clipped and there is a relatively equal relationship between stops. Interestingly enough with this profile, and maybe it is unique in this regard, it has very accurate colour. Unlike Sony's S-Log or Panasonic's V-Log it's not necessary to correct for unusual colour reproduction. Just set a good white balance in ACR, apply a curve and colours are (almost!) bang on target.
    If you've never used a DCP profile before read more about it here:
    https://www.magiclantern.fm/forum/index.php?topic=20710.msg191757;topicseen#msg191757
    Here is a ZIP file with the DCP and with two kinds of curves, one clean one with a "filmic" colour cast. You get both as a LUT and as a curve file for your convenience.

    GH4 - In VFR (Variable Frame Rate) shooting mode, there were cases where the image stabilization did not operate when non-Panasonic interchangeable lens is used. This bug has been fixed.
    H-HS030 - Macro - Dual I.S.2 is available by this firmware update. (in case of the usage of Camera with this function)
    H-NS043 - Nocticron 42.5 - Dual I.S.2 is available by this firmware update. (in case of the usage of Camera with this function)
    GH5 -
    1. Compatibility with "LUMIX Tether" PC software
    This new firmware enables GH5 tethered shooting via USB, using “LUMIX Tether" PC software. Users can control the camera by connecting it to a PC via USB.
    Click here to the LUMIX Tether Download Program
     
    2. Improved auto focus performance
    - Auto focus performance for subjects with low contrast in photo shooting is improved.
    - Tracking auto focus performance in video recording is improved.
    - The customized AF area can be continuously displayed in [Multi AF] and [Custom Multi AF] during live-view.
    - The AF area in [Multi AF] can be moved to the other edge (side, top or bottom) when it reaches one edge.
    - The start point of AF lock can be set on the live view screen in advance in [AF Tracking].
    - The AF area can be moved while the shutter button is half-pressed or while recording in [Burst Mode], [6K PHOTO] and [4K PHOTO].
     
    3. Improved performance in [6K PHOTO] and [4K PHOTO]
    - The waiting time to start the next burst shooting sequence after [6K Burst] and [4K Burst] is shortened to less than half the time.

    - [Video Guide Line] is added to display the image in a variety of aspects, such as Cinescope, 16:9 and 1:1 while recording video. This can be used not only in Anamorphic mode but also in other video recording mode.
     
    7. Enhancement of Body I.S. (Image Stabilizer)
    - [I.S. Lock(video)] is added. This powerfully compensates for handshake when the viewing angle is fixed.
    - A new handshake correction mode is added, which provides optimum correction when using 2.0x and 1.33x Anamorphic lens.
    - In VFR (Variable Frame Rate) shooting mode, there were cases where the image stabilization did not operate when non-Panasonic interchangeable lens is used. This bug has been fixed.
     
    8. Correction of white balance setting
    - When the K (Kelvin) value was changed after adjusting the color temperature with 2-axis white balance compensation, the setting was reset. This bug has been fixed.
     
    9. Improved usability of Time Lapse Shot
    - The time to finish shooting and the number of recordable pictures are displayed on the stand-by screen.
     
    10. Improved usability of Power Save LVF

    dxotic reacted to Amazeballs in Manual focusing on fly-by-wire MFT lenses   
    I just bought a used Pana 25 1.4 and besides its stunning imagery, I was very surprised by its manual focus capabilities, which was unexpected to me. This lens was produced back in 2011, but its the best manual focus fly-by-wire native MFT lens that I've used so far and by a great margin. I own 14-140 zoom (3.5-5.6), 42.5 1.7 and 20 1.7. They all are PITA for manual focusing, especially 42.5 1.7 which I would consider otherwise a superb small and affordable lens, but its MF is just so wired - one second very slow, then suddenly blazing fast. Completely unreliable for video and I hate its unpredictable acceleration and speed. Who's genius idea was to setup modern MFT lens behaviour like that? The 25 1.4 has fast smooth MF with close to none acceleration so I can easily pull focus on any shot without any extra effort or shaking my camera. Its reliable and constant. But all other lenses I've tried are plain terrible at that!
    So I wounder, WHY PANASONIC MAKE THEIR CURRENT LENSES BEHAVE THIS WAY?!  
    And it would be so EASY to correct, just by adding some extra menu setting with a profile for every lens for a) acceleration control (starting from zero) and the lens speed itself. Only two freaking parameters and thats all. That would safe so many people from constant struggle with that MF flybywire bullshit. 
    And now try to explain my why its not done yet? And consider that Panasonic stronghold is video, they are perceived by many as video camera makers, they excel in video.. but, they did not offer any solution in that department for all this years. Unexplainable idiocy. 
    BTW, maybe some hero hacker can modify MFT lenses firmware to change those parameters? That would solve this too. 
    P.S. Well at least now I have one lens with which I can focus comfortably.
