There is the potential to learn from errors.
- No 10 step greyscale was done, because ("how many more hours would we like to remain here.."). Greyscale tracking on the Minolta was ok, on the i1pro not so much so.
- Their understanding of Gamma is somewhat flawed - which is understandable, since the video was shot before the whole bt1886 debacle the industry used to cover their tracks - but I actually found it useful to hear what they used in their "internal decision making", which they voiced. ("I like that better".)
- None of them actually was sure about which device would be "more accurate" on OLEDs, with the benefit of the doubt going to Heron, because, Scott W. loves those numbers, once they pop up. VERY educational.
- The TV was characterized as "perfect" multiple times, mostly by Scott W, although its saturation tracking was abysmal.
- Now "lets watch some movies!"
- Brightness was corrected "by eye" after setting it with test patterns
- Scott W didnt know if Samsung used black frame insertion in Motion flow options...
- The off contact calibration was done with room light present, thanks to Scott W.
- The on screen menus brighten up the picture of an OLED which doesnt have a backlight?
That said I very much liked the video on a process level - because one of the guys, just forgot all ramifications and wanted to use his 1000 USD Meter and his 1000 USD software and his 1000 USD pattern generator to look at numbers, while the measurement run with the i1pro showed an entirely different greyscale and massive problems in saturation tracking. Which, from the look of it Calibrators before Calman 5 didnt even bother to notice. Those must have been simpler times - where youve got your calibration paycheck for looking at three colors that youd probably never see in any material.
Also, the steps must have been right and all in the right order, because Scott W definitely is all in favor of "stop thinking entirely and just follow the steps in the great 1000 USD software which prints a report in the end".
If there is something that anyone might take away from this by proxy - is to be very critical of the process as much as possible, even while learning, and by showing two different calibrations of one device - this video serves to underline this.
In the end the calibrations (steps) were done somewhat correctly - so you might learn something on the basic level as well.
Comparing this to the other "free" videos that are floating out there - I'd still recommend this, flawed as it might be...
