  1. Not really sure what those 2 videos are supposed to demonstrate.

    In the case of Crowder he conflates a different issue (the potential effect of price caps on a small ISP) with net neutrality.

    Both videos use whataboutism to deflect away from the issue.

     

    I don't think either video will educate anyone on anything.

    Ive attached a little clip of what I mean of a shot from last night, one clip is graded slightly, then the other ungraded and you can see as there is light on his body, its no noise, the moment the light goes away it ripples with noise all over? Any reason why?

    You're seeing exactly what you should be seeing.  It's just that with ungraded log material it will be more obvious.  Parts of the image with plenty of light will not suffer from noise.  Other parts of the image that are low light will show noise unless noise reduction is applied in camera.  This is just the physics of the situation.

    To see less noise without using noise reduction, you have to increase exposure (more photons hitting the sensor).

    I think if it were wide gamut and colour management they'd see less saturation not more.

    Maybe it is just taste. Bad taste. Liking stuff to look flat and grey. Who knows. That is in fashion at the moment after all.

    If you view a sRGB gamut image on an 100% AbobeRGB gamut display without colour management, the saturation will be higher than expected.

    If you view an AbobeRGB image on a 100% sRGB gamut display without colour management, the saturation will be lower than expected.

    Does anyone know how you change Kelvin settings with the D5500? A lot of articles state that you can, but I don't see anything in the WB menu for it. 

    The info out there is a bit contradictory, but I've not found a way to directly enter a Kelvin value on my D5300.  The cool white fluorescent WB setting should be a Kelvin value of about 4200 and that can be fine tuned either way.

  5. There are tools that that can demultiplex the streams out of media files then remultiplex back into a single file container.  When you do that you can specify the frame rate of the output file.  Any audio stream will then be the wrong length in the new file unless edited.

    Videohelp.com is a good repository for these type of tools (MP4Box GUI is an example that outputs mp4 files without re-encoding).

    Some of you saw my skin tone comparison with the GX85 and GH4 that I uploaded last week and most people seem to prefer the ungraded image from the GX85 . That's fine with me as both grades were a little off. But I obviously had to take a closer look to see if I agreed. I suspected that youtube is doing something with the colors when I upload in 4K and it seems I was right. I uploaded a 1080p version and made a side by side comparison. For some reason youtube seems to add magenta when uploading in 4K. The result is that the ungraded footage of GX85 looks better and the graded image (which was a little too much in the first place) looks a lot worse. 

    Has anyone else noticed this and is there a way to avoid it? 

    4K is on the left and 1080p on the right. 

    If I was to hazard a guess, I'd think you've got a colour space conflict.  Youtube might be expecting that 4K uploads are in Rec.2020, but I don't know.  I couldn't find any recommendations about that.
