Choppy playback in macOS Monterey on M1 Max

Hello there,

It seems like Infuse is skipping one or two frames every second given a MKV HEVC 4K HDR file. Device is an MacBook Pro 16" M1 Pro base model. Please let me know how I can extract more information from this file for diagnosis.

At first I assumed it was the file’s (torrent’s) fault, so I went and bought the movie on Apple TV. Recently I went back to it and decided to open the file in VLC. Surprisingly, there was no stutter at all. This is most apparent in panning shots where playback would skip a frame.

Could it be a network issue? I.e. Could Infuse be fetching/scanning files in the background causing more load on the network? Again this stutter does not happen while using VLC.

@james Would like to report I am hitting pretty severe judder on 7.3.8 on my 14" M1 Max, but only in full screen. Windowed mode no issue. Can provide files if needed. I’m just watching an SDR 1080p HEVC file.

I am really surprised that there is no fix for this.
I have 3 workarounds though, since almosteverything I watch in Infuse is in 23.976p:

  • manually switching display to 47.95Hz when using Infuse (and not forgetting to set it back to Promoion afterwards)
  • using ffmpeg (FF-works) to remux everything to .mov and use QuickTime Player,
  • if you have SwitchResX (I have been using it for years) set up an app rule that switches the display o 47.96Hz whenever Infuse is running and back to its original settings when Infuse stops running. Other display utilities might offer similar features.

My favorite solution would be Infuse to actually work when ProMotion is enabled but I am no longer holding my breath.

Still hitting this on 7.3.10. Only in full screen. 14" M1 Max.

The frame cadence almost looks to me like there’s a consistent interval where frames are not delivered.

Given how long this has been ongoing without resolution it would probably be prudent for the Infuse engineering team to schedule time in the upcoming WWDC labs to get advice on this issue.

I am also experiencing the full screen stutter on my 2021 16” MacBook. Bookmarked.

Same problem. MacBook Pro 14. Amazed there’s still no fix. Come on, you’re better than that.

I’ve been experiencing this for awhile on a 14" M1 Max. Today I upgraded to Pro (lifetime) and suddenly everything is buttery smooth in full screen with ProMotion enabled. Seems like a red herring but figured I’d pass it along if it helps the devs. Running 7.3.10 (7.3.4085)
