Ihave recently upgraded my old Roku 3 to a Roku Ultra. I had no issues with Emby playback on the Roku 3 but am experiencing constant/permanent video stuttering with some movies on the Ultra. There is no issue with the audio. The movies are x265 .mp4 files (although as stated, some seem to play without an issue).
From reviewing the community posts I understand others have had this issue with Emby and one possible solution is to downgrade the quality settings to force transcode. I have tried downgrading to various quality settings (as low as 480p) and it does not fix the problem (the stats for nerds output shows DirectPlay even at the lower quality settings).
I really don't want to have to use Plex if I can avoid it (or reformat the files to .mkv using MKVToolNix which I understand may be another solution) so was wondering if there is anything else I can try?
Notes:
- Hardware acceleration is switched OFF in Emby server
- Allow HEVC at 60fps is switched OFF in Roku client (switching it on makes no difference)
- As stated above, reducing video quality does not fix the problem
- Switching subtitles off makes no difference.
Hi. Under the "cog" menu during playback, there is an option labeled "Playback Correction". Can you try choosing that and see if that solves the issue? You can choose it multiple times until the player finally gives up.
Thanks @ebr! I had also tried pressing Playback Correction originally with no luck (forgot to mention it my post - sorry for that), but pressing it multiple times fixed the problem and I can see in stats for nerds that the file is transcoding now. Thanks again for your help!
The issue is the MP4 you are attempting to play is not streaming friendly. The Roku cannot accurately judge the end of file with some headers on some media. You can tell if this is the case with your file if it cannot be resumed and always starts over at the beginning. Because the Roku must fully download the entire item because some part of the header is stored at the end of the file. A header should always be stored at the front but for some embeds there is no other way. Because the container does not support it. So they just put things inside an MP4 that do not belong there. There is extra data at the end of the file to make up for those extra things that could not be contained inside the header. That makes the file not streaming friendly because they used the wrong container.
To convert those problem files into MKV is very simple. Just drag the MP4 onto MKVToolNix GUI and tell it start remux. It will take a few seconds. Once this is done the file is streaming friendly and the Roku can read the entire header for the file and accurately judge the framerate, the end of the file, etc. In other words you can fix the mistakes the encoder made. It will not impact video/audio quality as all the streams are copied. You are just going to change container and rebuild a new header with accurate information based upon those streams inside.
The MKV container is much more tolerant of what can be embedded. Subtitles, codecs, etc are much more friendly within an MKV container on the Roku. When you encounter problem files like this try a quick remux with MKVToolNix GUI and immediately have proper playback without transcoding. This best solution isn't transcoding that file every time you want to watch it. The best solution is fixing the file so it plays correctly without glitching your Roku player requiring you to transcode.
Thanks for further info @speechles, I understand converting to mkv using MKVToolNix is a solution and the program itself is easy to use but at this time I'd strongly prefer to avoid that. Fortunately the Roku has no issue pausing/resuming playback on the affected files, it is simply the stuttering issue. Solving it with two clicks on the fly is a better outcome for me right now although I'll definitely keep the mkv convert in mind as a longer term solution.
Ultrawide monitors have been on the go for years, but the idea of a screen with a 21:9 aspect ratio in the TV space has never really taken off. Other than Philips releasing its legendary (among people like me) Cinema 21:9 LCD TV over a decade ago, the modern television market has never really had a place for non-16:9 displays.
Most movies are now filmed in Widescreen Cinemascope format, which equates to a 2.35:1 aspect ratio. With the 21:9 format measuring in at 2.370:1, ultrawide screens are pretty much perfectly placed to show movies in the manner directors intended.
This has a little too much production value and motivational music for my tastes, but still a good film about a cool race I knew very little about until a few years ago. The 2020 field included Jim Walmsley, Stian Angermund, Maude Mathys, Tove Alexandersson, and many other great runners.
Nike runners David Laney, Tim Tollefson and Zach Miller showed that Americans can compete in the classic of series of European ultra running. Billy Yang covers their efforts in classic, highly personal form with characteristically gorgeous cinematography.
This short is wonderfully silly mountain race between mountain running legend Kilian Jornet and base jumper Tom Erik Heimen (who gets to fly down). Who makes the roundtrip faster? Who thought this up? How did they not die? Welcome to the Romsdalshorn Challenge.
Okay, this movie has nothing to do with running, but to me this is the defining movie about endurance, grit and just keeping moving no matter what (aka the Dori principle). Come for the crazy story. Stay for the crazy story.
Armed with the new Bose QuietComfort Ultra Headphones with Immersive Audio enabled and paired to my Apple TV 4K upped the fear factor thrills while engrossed in my favorite horror movies. Read on to find about my horrifying spatial audio experiences that changed watching my favorite Halloween movies forever.
The setting in a horror movie is important. It not only adds to the atmosphere, but also primes scares and a sense of dread. Spatial audio did a fantastic job of immersing me within these environments.
If the nurse station scene in The Exorcist III gave you night terrors upon first watch, then experiencing it in 360-degree sound might keep you awake until the morning. The scene is filmed perfectly, highlighted by a one-shot frame focused on an extended hospital corridor that sets up a fake-out scare followed by the real thing. To say I was incredibly startled once the close-in visual and loud music sting hit simultaneously would be an understatement.
Previously, the excellent Yamaha YH-L700A filled my spatial audio needs for all media content, delivering impressive 3D audio with video content modes (Background Music, Drama, Music Video) that complemented intended media.

It was released on August 21, 2015, by Lionsgate. The film received mixed reviews from critics, with praise for the premise and cast, but criticism that it "fails to live up to its potential".[6]The film underperformed at the box office, earning a worldwide total of $30.3 million against a production budget of $28 million.
Mike Howell is a stoner who lives in the sleepy town of Liman, West Virginia, where he works as a convenience store clerk. He is planning to propose to his longtime girlfriend, Phoebe Larson, on a trip to Hawaii. He is unable to board the plane, as he suffers from intense panic attacks anytime he tries to leave town. He does not understand why Phoebe puts up with him.
In Langley, Virginia, CIA Agent Victoria Lasseter receives a coded warning that Mike, the sole survivor of her "Wiseman" Ultra program, is to be eliminated by her rival, Adrian Yates, and his similar "Toughguy" agents. Feeling a duty to protect Mike, Lasseter travels to Liman and "activates" Mike through a series of code words. Mike fails to understand their significance, and she leaves in resigned frustration.
Mike finds two Toughguys interfering with his car and is attacked, but his training activates and he kills them using a spoon. He calls Phoebe, who reaches him just as Sheriff Watts arrives. Yates sends two Toughguy operatives, Laugher and Crane, to kill Mike and Phoebe at the sheriff station, but they evade Laugher and kill Crane before escaping to the home of Mike's drug dealer Rose. Mike becomes unnerved by an array of facts he suddenly knows regarding military strategy. He also realizes he has very little memory prior to living in the town with Phoebe, wondering aloud why he never questioned this before.
Yates quarantines the town, and puts Lasseter and Mike's pictures on the local news. Lasseter convinces her former assistant, Petey Douglas, to air drop her a weapon using a drone. Yates finds out and threatens to charge Petey with treason. Yates then attacks Rose's house with two Toughguys using a lethal gas. The agents kill Rose and his two guards, Big Harold and Quinzin, before Mike and Phoebe kill the attackers and she rescues Mike from the gas, which she is familiar with. When pressed for answers on her knowledge of the gas, Phoebe reluctantly reveals she was a CIA agent assigned to be Mike's handler, leaving him heartbroken.
Laugher ambushes the duo and captures Phoebe. Mike is rescued by Lasseter and insists on returning to his house. She tells him that he volunteered for Wiseman due to his criminal record and subsequently had his memories erased. He also learns that Phoebe was to get him settled in Liman and then leave, but chose to stay because she genuinely fell in love. Lasseter explains that his panic attacks, including his fear of leaving town, were implanted to keep him safe.
