It's notable to mention that I tried emby for android tv, and emby normal, both stutters. Also, jelly and plex, play it well and normal.

Karaoke and specials subtitles likes signs are buggy.

I was playing an anime series called Your Lie in April Episode 01
The intro has karaoke style ass subtitles, and when this shows the video stutters and audio its crackling.

Hi.  Can you try searching for our standard android app (Just "Emby" on Amazon and "Emby for Android on Google) on the same device's app store and see how that compares?

Thanks.

I have the same exact issue with the standard android app

HI, we'll look at this and try to reproduce. Thanks.

This is usually caused by potato hardware. Jellyfin and Plex by default burn .ass subtitles in, Emby does not. If you want this to go away, burn the subtitles in. 

Yes I have a large anime library, and yes .ass subtitles are a reason why I do not use a stand alone box anymore as .ass subtitles take massive resources that boxes do not have.

Any boxes? Even nvidia shield?

Yes. Anime is very hard, specially stuff that is styled nicely. If you want to keep the custom fonts, fades and transitions, either burn them in, or use a PC.

A lot of my older fansubs are absolutely unplayable on any Android box because of the amount of effects used.

Heck even the crApple TV can't handle karaoke subs well and will stutter and slow down, and at times crawl on its knees and beg for mercy.

Use a PC, get an air mouse. Sorry, it's what you need to do if you do not want to burn subtitles in.

I have a mini pc that can't handle ASS subs either. I either extract them or find subs in my language. PGSSUB is slightly better but when there's 4 people at the same time watching a PGSSUB video I can make toast with my mini pc.

If you really want to handle more intense transcoding like this, you should make use of a video card and let that do the transcoding for you.
Their GPUs are much faster at this sort of task than CPUs.

For video stuttering, please try Emby for Android 3.5.25 and let us know how that compares:
