GH4 video judder/strobing - a solution

I have ripped and watched a ton of 24p video over the years on my 60hz monitor with no motion issues or judder apart from when the camera pans too fast - which will cause judder anywhere, even on cinema screens.

Take the Planet Earth blu-ray for example. I own that and ripped it to 24p. Plays silky smooth on my computer, even when the camera glides over mountains, there's no judder. My own 24p video camera footage is also smooth and judder free - except when I pan too fast.

The answer is software. You don't need a new monitor with 48hz refresh rate, you just need a software player and codecs capable of handling 24p. There is likely some clever interpolation happening to achieve these results, but with today's software players taking advantage of graphics hardware acceleration, the task is effortless for your computer.

I use PotPlayer on my Windows PC, and it is hands down the best video player. VLC was good for many years, but when I moved to PotPlayer it was a step up. If you're on Mac, there are no doubt software video players that can play 24p without judder, although I wouldn't know for sure since I don't own a Mac.

Just thought I'd add this, because your suggestion of plugging in an external display with 48hz refresh capability is an extreme length to go to for smooth playback. Just get a decent software video player.

BTW, there's lots of 24p videos on youtube that users have uploaded, including GH4 24p video. Youtube supports 24p, just right click and choose stats to confirm it's 24p, then you can at least see whether your browser can handle 24p video. Some can't. 24p video in my Firefox browser is not pretty, lots of judder. The same video file when played in PotPlayer is smooth.
