Title: HFR movies- 10bit@48fps
Post by: 4Kready on December 23, 2015, 05:33:00 PM

Hi,

last night I tested H8 Octa with "The Hobbit An Unexpected Journey" (x264; 10bit; 48fps edition; BDRip-1080p; 29 GB file size) in mkv container ripped from HDMaNiAcS.
Movied played without stuttering and sound was synced but the colours were way off. They were like washed off and with a lot of noise, especially on darker backgrounds.
Did anybody else tried testing 10bit@48fps movies on H8 and will this HFR formats be supported in the future upgrades?

H8 doesn't support 10bit in hardware.

In what app did you play the movie?

Hi Futeko,

I have tried playing it in both Media Player and Kodi. Problem was the same in both players.

It seems that picture was fine in one moment and then it started to be more and more brighter (like you were increasing brightness on your tv) loosing the contrast and in the same time getting more artefacts, especially on darker scenes. After short period of time, when brightness was on its peak, picture would again be ok, resulting in natural colors and contrast. After a few seconds, brightness started slowly increasing again until its peak and again picture would go to normal. This was happening in the loop which lasted around 10 seconds or so.

Too bad if 10bit color depth is not supported in this chip because it seems that this hardware is more than capable of handling this bitrate. More so, like I already explained, it seems that H8 was struggling to retain color depth and succeeded in short period of time, so I was hoping that this would be solved in upcoming fw upgrades.
As a reminder, this movie was encoded in x264 in matroska container with framerate at 48 fps and bitrate was 20 Mbps.

Even I have played 10 bit video with H8 with the old firmware version.  But after updating with the latest firmware, H8 is no more playing 10 bit video.  The 1.1.3 firmware is having "Audio Dropout" issues as well.
