Got my Raspberri Pi 2 set-up to play with. First time with a Pi; it's an impressive, snappy little gadget for $70 (board + mSD card + power + case).

The only two things Q5 4K can't quite match Chromebox on are: (1) Proper 23.976 support, and (2) speed. But, when I was watching those two movies, I didn't notice any microstutters. And, while speed can't match Chromebox's, it's snappy enough. Nice to have just one (Kodi) box in my home theater now . Unplugged my Mede8er 600X3D as well after 2 years as my 2D & especially 3D rips workhorse.

One of the movies I watched from start to finish this weekend was 'Foxcatcher'. It has many facial close-ups & I could make out all the details (pores, hair, etc.). Also, on my Q5, as I have all digital processing disabled, the PQ was film-like (you know, that just-enough amount of grain, details in the picture).

You should see a duplicated frame every ~42 seconds.

On the Chinese version of the same box (slightly different hardware, firmware), I did notice the microstutters.Then why do you say it doesn't do proper 24/1.001 playback? If it doesn't have a repeated frame every 1000 frames then it might just have proper playback.

Quote:23.987 still not supported. We pushed many times on HiSilicon company. But they still not give us exact date

Some users may be more susceptible.23.976 is a rounded off representation of 24/1.001. The true framerate is 24/1.001. If you play 24/1.001 (23.976) content at 24Hz you will either get a duplicated frame every 1000 frames or you have to play it back slightly sped up which will cause audio sync problems if you're bitstreaming. If you decode the audio to LPCM you can keep the audio perfectly in sync with 24Hz playback of 24/1.001 (23.976) content. The problem with this has been the lack of an open source decoder for DTS-HD (MA). One now exists and is in the process of finding its way into various projects.

Q5 don't have official support for 23,976 ,from HiMedia:
But with motion bar test file i can NOT see any shutter, with film 1-4 shutter not always.
The same test file with amlogic s802 i see a shutter every 41 second (SPMC/dvdplayer).
