I ripped Batman v Superman the other night (full BD rip in MKV container using MakeMKV with no alterations, keeping only forced English subtitles and the Dolby TrueHD 7.1 w/5.1 DD core) and when I play it on my Shield or in a web client, the audio has to be transcoded due to the TrueHD track. The issue I have is that during any high movement scene or explosions, the entire screen fills with horizontal colored bars. If I drop down to 12MB then the problem stops. The movie plays perfectly in PMP.
This is the only title I have that has this problem. Any ideas why this is happening? I’ve attached the XML, and tonight I can grab a chapter and upload it for review. I’ll take a small video of the anomaly tonight and add it here.
I can tonight. A bad rip doesn’t seem like the issue for me, since it plays perfectly fine unless at max bitrate video and transcode audio. I can definitely rip it again to make sure.
HDCP / DRM issues would not show it self in this maner to my knowledge, but since you say it only only appears on high bit rate scene it would indicate a ripping issue, or some other from. How is it if you play the media out side of plex? like VLC or MPC-HT

Definitely not DRM. It only shows up when the audio is being transcoded - if direct play is available (like on PMP) then the video is flawless. It is also flawless if I select 12MB for the bitrate instead of original. I haven’t played it using VLC yet, that is on my to-do list for tonight. I have put it on a different Plex Server and the same tearing issue happened.
While I’m testing the MKV and making a small test file I’m going to rip it again to verify that is/isn’t the problem.
Well, I re-ripped it and it still has the horizontal colored bars when I have audio transcoded and the video at the original bitrate. I’ll cut out a piece where it seems to happen repeatedly.
I’ve used two different machines to rip this and it still ends up the same. To get this to happen, I play the file with the 7.1 track in original bitrate.
VLC will play it without issue. Audio cuts in and out with 7.1, switching to 5.1 fixes the audio.
Windows 10 default movie player shows the color bars/tearing.
Sounds like the reference frame issue they are having across multiple platforms and movie studios. If you read up on it, they say it is predominantly Sony produced movies, but I am pretty certain I have seen it on a WB disc before. Check you media info, if you have a ReFrames of 2, but that is it.
FYI I have reported this month’s ago and no improvement or development from the team thus far. Just a workaround to transcode these videos.
@hatflix, thanks for the good info. I’ll look at my xml and verify. Must be an issue for Windows as well, since it happens with the default Windows 10 video player.
Curious if you’d get different results on a non-windows server, now that PMS relies on the OS for it’s codecs, and I know the WMF stuff has some wonky limitations (as you are seeing in the default video player as well). Do you have access to a Linux or Mac PMS setup you could test it on?
Also, as an aside…why is it always Sony discs that break everything? With DVDs it was their horrid DRM that wrecked the playback order, and now this.
@jkalland, I doubt it, since the file has the same problems when using the Windows 10 video player. I also loaded a much older beta release of PMS and it still happened.

Ah, OK. If an older PMS did it, that likely rules it out, as the older ones didn’t rely on the OS for codecs quite the same as the new builds (I forget when that was split off, but I think it was one of the last few 0.x releases). I was actually curious BECAUSE it had the same issue on the Win10 video player. As I understand it, new PMS builds rely on the WMF codecs on Windows, which would be identical to the native video player.
I believe this is the same issue I was able to replicate when using the NVIDIA Shield as a client and Interstellar. I saw the colored patterns were consistent in look and time during playback when Direct Play was set to Auto, transcoding at Original (due to audio). The same file played back on the Apple TV produced skips in the exact same spots, but no colored patterns. The colored patterns or skipping were not visible when transcoding at less than Original. This appears to have something to due with H.264 playback via HLS or ref frames. We have an issue ticket filed (guess by who…) and I have added a reference to this thread. It would be helpful if client logs were posted to help investigate. I have also pinged a transcoding dev to make sure they get eyes on this.
Hey sorry I’ve been away a few days, I have checked your sample, and same issues is apparent on my system with that sample?
Windows Media Player : Plays with errors
MPC-HC: Works just fine
Plex: Looks about right. Tested in Chrome webapp and Plex Media Player.
What are the settings you are using in makemkv?
My rip of this very same movie does not display this behavior.
@Night, makemkv has no settings. You just rip the file. This is a full rip with original bitrate, there is no transcoding. Where did you get your BD? I have the 4K + BD Amazon version, and this is from the BD disc. Also, verify when you play your rip that it’s set to original bitrate - because if it’s doing any transcoding at all you will not see this problem.

Bought the BD from a local shop here where i live. (none 4k version). I did check wather or not transcoding was in affect. All tests were in direct play.
