Every UHD movie I try to compress to BD50 is pixelated

Diaboyos

I just got a new GTX 1060 6GB SSC and so far I've compressed about 10 UHD movies for backup to BD50. The problem is that every compressed file has pixelation in it. Not the usual pixelation that you think of but large squares. Like pixelation zoomed in 200x. It's not constant but often enough to make the file unusable.

I've run multiple different types of benchmarks that came with the card to test the card and it passed them all easily. Additionally, I ran Heaven Benchmark for 4 hours on Ultra and it didn't produce any errors. I can still compress BD50 to BD25 with no pixelation. This is only happening when I compress BD100 to BD50.

What doesn't work when compressing to BD50:
- Full Copy
- Main Movie
- Rip to MKV

What does work:
- Rip to MKV Passthrough (because there's no compression)

I've included some screens that show the original vs after compression to BD50 (). I've also included the log to the title used in the screens if anyone notices anything that may indicate what the problem is. Logan.txt

Does anyone have any idea what's causing this? Could it be a problem with the card even though it does everything else with no issues? Or is compression from BD100 to BD50 still not perfected? I need to know if it may be the card while I can still return it.

Anyone have any ideas on this? It's not the card. The only reason I thought it might be was because the fans on it didn't spin up when I first installed it. But I later learned that's how it's supposed to work unless you have Precision or Afterburner or some other program running to control the fans that they won't kick in until around 60 degrees or so. I have Precision installed now. I've run several more benchmarks. The card comes back good every time. But everything I compress to BD50 is pixelated. BD50 to BD25 still works with no problems.

Tried compressing to BD50 with the new 10.0.79 last night with a few movies. Tried Full Disc and Main Movie and every one still has pixelation.

Please post the fabcheck_internal.log file as well.

I'll have to clear the log and compress the movie again tonight and then post it. That log is all jumbled together going back forever and I can't find this particular movie.

Diaboyos... I am experiencing the exact same thing. I have tried several profiles but I always get large block pixelation. I am using a GTX 1050 Ti 4GB.

OK I tried to compress the movie again last night, Full Disc to BD50. It's still pixelated as before. Here are the two logs. [ATTACH]n348703[/ATTACH] [ATTACH]n348704[/ATTACH]

Hi Diaboyos,
From our dev.
This is nvidia bug in decoding hevc 10bit video, they fix this until driver 387.
Please update latest nvidia dirver from offical site.
Then give a try.

Thanks.

Many thanks - that fixed my issue.

Diaboyos

Thx I see they released a new driver just two days ago. I'll install it and try again tonight.

Diaboyos

Thx the driver released on 1-29-18 fixed the pixelation problem for me.
