TVHello people,
i bought this tv on black friday so it's new.
But when i was trying to watch Witcher 4K HDR from a usb 3.0 external hdd (i had to download because my internet connection is 6mbps, otherwise i have netflix account. ) i had playback problems such as stutter/freeze/image corruption etc.
The images was getting corrupted/blocky and A/V was stuttering and freezing. I thought maybe TV was just not powerful enough to play this but for a new TV it was unlikely.
Then i realized stutters were happening when there was talking, and i saw there was more than 25 subtitles in the movie file including weird ones (chinese etc.)
Even though i disable subtitles or choose a subtitle from the enormous subtitle list, the playback stutters when movie encounters a subtitle.
So i removed the subtitles except English and Turkish from the file to try it out and now movie playbacks nicely. When you have a small list of subtitles there is no problems.
I'm not sure if the number of subtitles or weird subtitles creates this problem, even tough disabling subtitles doesn't resolve the problem unless you remove the subs from the file itself. (MKV container)
Samsung engineers might pinpoint to problem and fix.
Thanks for reading.

TVI have similar problems with a 4 year old TV UE49KS7000 (2016) ever since I started making 4K videos. I play them from an external HDD (WD Elements). An HDD without its own power source. I have tried converting my videos to different codecs (H2.64, H2.65) file formats (.mov and mp4) and bitrates, but nothing helps. It is difficult to say what kind of scenes are more likely to stutter. Usually these are scenes with quite some movement. Footage is shot with different cameras (Sony A6300, FDR A53, Gopro Hero 5, computer generated animations). I have also tried to play back from a Samsung T5 SSD drive. Same result. It is not like the whole video stutters, but it happens at a few specific scenes in a 50 minute video for 10 to 20 seconds or so. When I play back on my iMac the video runs smoothly. No problems with 1080p videos either. But that is not what I bought the S-UHD TV for! What is critical here?

TVthe problem i explained is about subtitles. if there are quite a lot subtitle files (or different languages like chinese/greek) in the media stream even if you don't choose a subtitle to show on screen the video playback stutters when a subtitle string is encountered in the background.
but our moderator here doesn't think it's an issue worthy to be forwarded to the qa/dev team. so.
and for your problem it might be about image processing, try to disable all the smoothing etc. because smoothing makes the action sequences look stuttery, it only works in basic shots.

TVHi. I am facing the same problem on my 7series Qled tv from 2018. How do you remove the extra subtitles and can you give step by step guide?

TVi don't remember all the steps but basically i have downloaded an open source tool called mkvtoolnix, dragged my movie file into sources window and then it will show all the streams in that file (video, audio, subtitles)
remove the subtitles you don't want and save a new target file and start the process, it can take some time if the media file is big

TVAfter months of trying to figure this out, you finally helped me solve an issue that had me practically pulling my hair out!!! This makes everything work perfectly! Samsung really needs to fix this issue, but it is nice you were able to find a workaround.

TVThanks Muratbalci - this worked for one of my Samsung TVs - removed all but English subtitles: stutters gone!
Samsung really need to fix this - theyve added so much ***** we don't want and the simple things we do, like these - have issues 😞
