PS5 stuttering (duplicating frames) every 7 min (4 months research already with no fix)
Usecase: Im playing (and recording) PS5 games with OBS preview, im pretty much okay with the latency, so i did not buy another monitor for this.
1. PS5 4k (no VRR no ALLM, sound PCM).
2. OBS latest, FPS 59,94.
3. Capture source: 4k, 59.94, nv12, buffering off, color mode: limited.
--------
4. PC: i7-9700k, RTX-4090.
5. Capture cards that i have tryed:
5.1. Elgato 4k60pro mk2,
5.2. Avermedia GC575 Live Gamer 4k 2.1 (new one), a
5.3. USB-C from avermedia Live Gamer Ultra 2.1.
3 capture cards - all with the same issue.
Tested on both PS5 Digital and PS5 Regular.
PC games runs smooth. Playing 120fps record at 59.94 super smooth. For PS5 there is no case to enable 120hz - it is choppy as hell. (On passthrough it is smooth btw)
The Issue:
I have microstutter (duplicating frames) every 4-7min which is persist on recording.
1. For elgato card it was every 4min.
2. For avermedia 4k 2.1 it is every 7min.
Tested with 720p resoulution for OBS and PS5 - no effect. With new empty scenes etc, tried everything except changing PC.
On passtrough there is no lag at all, it is only in OBS preview. (also in native apps from avermdeia and elgato the same stutter)
Camera (59.94) not lagging at all. it is only for PS5.
I have monitor Samsung CRG9 49" - i have even set custom RR for 119.88hz and 59.9400
Interesting thing that this lag persist even if im not recording, just playing through the OBS preview.
Also this stutter is a simple duplicating frames, and they are completely dissapear if im enabling DEINTERLACING MODE: DISCARD for the source, but the quality is bad with this.
Any suggestions thoughts?

Well that deinterlacing mode is dropping it to 30FPS so you’re just not seeing the stutter at that point lol
Eugene•34d ago
indeed, but video is super smooth as native 60
maybe u can guide me a bit where to dig? im still suffering from dat microstutter... every 8min or so it just spams double frames for 10-15 sec

If I had to guess I'd say you're just running into a quirk of using a relatively complex set of tools. It's a lot asking Windows, capture hardware, all the associated drivers, and OBS to play nice with each other perfectly. Knowing how bad just Windows' audio system is it shocks me capture devices even work let alone work well.
Obviously you could try troubleshooting more, maybe even spin up a Linux ISO to see if the issue persists there. You could also try ensuring your framerate is an even number across all devices and configurations. 59.94 is obvously the standard, but have you tried 60 on everything? You could be running into a drop frame encoding or rounding error somewhere in the process that MS/OBS/Elgato/Avermedia haven't or can't account for.
It's tough to know what the issue ever is. Heck, it could literally be some RGB control software refreshing in the background causing issues....
Also, if you're recording to MKV files and then remuxing them to MP4s, that can cause a rounding error issue since the containers use different formats for timescale
Technically Alex•33d ago
I use this bat file to remux 60FPS footage
Technically Alex•33d ago
it assigns the timescale and fixes the frame drops/stutters I've seen with MKV to MP4 remuxes that don't account for timescale
just change the -video_track_timescale XX value to whatever your recording framerate is for the file
so 59.94
Eugene•33d ago
thx, but im ok with mkv, no need to remux.
issue happens even without recording, its not obs related , cuz persist in every video capture tool, even ps5 recordings on itself have this weird lag if im playing not with the passtrough.
might be fps drops on ps5… but on a passthrough it is not visible…
on 60fps i had fps drops every 5 seconds or so. worse.
EposVox // Addie•33d ago
uhm
if it's affecting even the PS5 local recordings then it's just drops in the game
or something
nothing to troubleshoot lol
DiamondRyce•33d ago
^^^
sounds like you need to clean out your ps5 or change out the nvme drive thats in it.
Technically Alex•33d ago
Technically Alex•33d ago
just tbc, any time you go from MKV to MP4, like exporting from an NLE, encoding on YouTube, etc. you run the risk of causing the timescale conversion issue
You might be fine working with an MKV workflow and I'm not saying you shouldn't. I'm saying it's literally a concrete issue with switching containers that most people don't realize and will impact the quality of your footage if it happens.
Eugene•32d ago
could you give an example of timescale conversion? what is it - im not good at this.
MEE6•32d ago
GG @Eugene, you just advanced to level 1 !
Eugene•32d ago
understand, but when recording on PS5 trhough the TV (without capture card etc) it is smooth AF, im just sitting and pan the camera for days checking different setting.
The game is The Last of Us (both parts for ps5) and God Of War - testcase: just sitting at the same location and slowly pan the camera around...
this is driving me crazy. the lag itself have visually the same as if i select 60fps for 59.94 footage (lag happens every 10seconds), but if everything is on 59.94 this lag/stutter happens every 8min.
Maybe other ppl have it as well and very few ppl just bothering with it and suffer ))
EposVox // Addie•32d ago
A capture card cannot affect what the internal recording of the ps5 does
Eugene•32d ago
yeah, thx got it! But what can cause lags in case when im playing via Passtrhough and get no lag at all (no vrr, no g-sync, no allm), but in OBS preview it happens every 8 min ?
2 monitors: 1st passthrough (no lag), 2nd PC view for OBS preview with lag at the same time
DiamondRyce•32d ago
Have you tested with an hdmi switch or matrix instead? Maybe just not use the passthrough on the capture card
Eugene•32d ago
nah, i think any additional peripheral adding even more delays etc
EposVox // Addie•32d ago
The passthrough isn’t the problem, the capture is.
I just noticed you said you turned buffering off
Turn it back on
That’s probably the whole issue
Doesn’t explain the on-ps5 capture and I’m not about to troubleshoot that
But buffering should be left on
Eugene•32d ago
ill try out, thx! hope dat delay will not kick me
EposVox // Addie•32d ago
kick you?
Eugene•32d ago
i mean will not bother me, cuz i mostly playing on 1 monitor with projecting, i cant realy play well using PbP with my 49" monitor - somehow it goes laggy ... a lot of issues - but i cannot figure out even how to ask questions.
even diggin into PCIe lanes, though it is something slowing fown my capture cards.
EposVox // Addie•32d ago
well playing from the preview is gunna suck for most games
Eugene•32d ago
im casually playing offline games just for story mode
@//addie thank you anyway! if i will figure something out - will let you know here in comments. Mostly watching your YT for educational purposes - thank for that as well.
but still deinterlacing: discard for me was like a fix (but graphics is a bit corrupted, text TOO sharp etc, but it keeps looking as 60fps smooth with no lag at all. Though it will bring someone to ideas of pottential fix.
Thank yoU!
EposVox // Addie•32d ago
discard just literally throws away half of the frames and every other line
Eugene•32d ago
it throws away those duplicated frames for me as well somehow.
Ive just watch my lags in DaVinci frame by frame - thats why i know it is duplication...
MEE6•32d ago
GG @Eugene, you just advanced to level 2 !
DiamondRyce•32d ago
Then follow alex suggestion. You may be running into the timescale issue he mentioned
Eugene•32d ago
the lag is in obs preview, even if not recording - does not matter mkv/mp4/bitrate etc
