I know that there are some very action packed scenes in the movie but does it stutter even in the scene in the sample for you ?

@k2u3 - Yes. It stutters in the sample. Didn’t stutter on yours?

cant test right now

If it helps, that sample stutters on Vero 4K+ for me. However it worked fine with no stutter on my TV’s built in player (LG B8) and with Plex app (direct play) on the TV.

@Zooicidal thank you for testing. This confirms I’m not insane haha

Are you playing from local or network storage?

Sam

Difficult to say - the clip is so short it scarcely gets started before it’s finished on Vero. On my PC (Phenom II x4 955, s/w decode by Kodi) it stutters like heck.

local

Sorry. I was trying to keep it as small as possible. I’ll reupload a longer sample.

@grahamh sample video should be longer now. I’ve changed the link on the first post. I’ll add it here too sample file

I haven’t tried the video on the Vero’s beta yet. Maybe it’s already fixed there?

No. Still stutters as they are going down the steps.

Thanks for trying @grahamh. Yes, that’s the part where it stutters.

Maybe it’s just a bad rip? Although it plays without stuttering on my TV’s player it has a visual glitch at the exact point where it stutters on the Vero instead. You can see it here Imgur: The magic of the Internet

It’s on the list.

I happen to have exactly the same file, look at Unique ID in media info log to confirm and mine dosen’t seem to stutter while OPs sample did stutter

Here is a sample of my file: watersample
rar pw is osmc.

Can someone confirm ?

If the file plays fine for other people I guess it could be that the file was somehow corrupted when OP created it on his HDD or SSD I had that problem with files corrupting because of a drive that was on its last lags before. SSD also can start corrupting files is its too full ( and not new anymore) in my experience

Yup. Looks like a poor rip

Can you check my sample as well please ?

Checked this. The file is dodgy.
This can probably be fixed by resetting the decoder and jumping to next IDR.
