Hi @johnebaker,

Thank you for the information.
The .318 patch seems to have fixed the basic stuttering issue with Nvidia H.264 renderings.
(I also tested it briefly with this UHD clip: https://pixabay.com/videos/snow-winter-nature-river-wharf-329674/ )

The saga continues... Definitely something odd with the 3060 exports (2720x1530 and 3840x2160 at various bitrates and also tried the UHD 5994 preset) on my TV (LG "4K"/UHD smart). I've made up a 1min 42 sec video of some drone footage with a soundtrack and the video definitely runs slower than the audio. The timecode display indicates at the end and the audio finishes but the video is still playing. This happens both through the network (Serviio) or off a SSD plugged in to the TV.

HD 1920x1080 seem OK.

HEVC is fine.

All files play OK in VLC Player on the computer.

Encodes with the UHD770 are flawless.

Must be something my TV doesn't like but the fact that the UHD770 files play without issue makes me wonder about the "standard" or "quality" of the 3060 encodes.

Greetings Al,

Ever since the Nvidia 590 series driver debacle just before Christmas 2025 I've had problems with my 4060 - possible slightly different to your because I'm using MS2025 which hasn't had the updates.

I rolled the driver back to 581.80 and I thought that all was OK but I had the audio sync problem and the quality of the encodes were, to my eye anyway, slighlty inferior to what they were before I loaded in the 590 series driver I can only assume that the "new driver" put something in the bowels of Windows that cannot be removed by uninstalling.

However I have been using the Intel 770 for encoding without a problem - as you've found.

While searching for something else on t'internet I came across a gaming forum that was discussing the Nvidia 590 driver issue and there was lots of talk about 1% Lows, which I have since read up on and don't understand a word of it.

Setting my ignorance aside, there was a section on benchmark testing for the 1% Lows using various drivers from 570, 580 and 590 series. The best of all by a large margin was a driver from the 570 series, apparently the higher the number the better a game plays

Now I'm no gamer so I wasn't that bothered until I found another forum where I read "1% lows in video editing refer to the average frame rate of the slowest 1% of frames, which helps measure the consistency of playback and can indicate stuttering or lag during editing. Monitoring these values can help improve the editing experience by identifying performance issues"

That also went right over my head but I thought I try that driver out anyway. I managed to fint it after a short internet search as Nvidia don't seem to have it on their site. It's "577.00-desktop-win10-win11-64bit-international-nsd-dch-whql" dated August 2025 and I installed it even though it's a Studio Driver which I don't usually use.

Whether it's wishful thinking on my part I don't really know but encoding with my 4060 seems slightly faster and the end qualty seems better using a couple of recent projects in a before and after scenario.

Third Party video players also seem to not have a flicker anymore and Shutter Encoder is now much faster for some things because Vulkan now actually works - Vulkan, something else I don't understand.

ps Apologies for the ramble but I thought you may be interested - unless you're a gamer of course😆

@me_again @AAProds @johnebaker @vdl-user-v19

I'm not sure if my contribution is relevant or not as I'm still using MMS 2024 and VPX 14 but I'm not having any quality issues with hardware encoding at 4K or HD at any frame rate from 60 down to 25fps using an nvidia 3060 12GB on my system still running Win 10. I went back to the 576.52 Studio driver and haven't bothered to update since. But that was initially to do with export problems I had with a photo editing app crashing / freezing that had added new AI masking tools as at that point I was only editing photos for a long time.

Hi Al

. . . . I've made up a 1min 42 sec video of some drone footage with a soundtrack and the video definitely runs slower than the audio . . . .

Is the sound track that of the drone or a music / other audio track?

. . . . The timecode display indicates at the end and the audio finishes but the video is still playing . . . .

I tested MP3 vs WAV in a 10 min, NTSC source video format project. On playback of the exported videos gave me the following:

• WAV audio ended on time.
   
• MP3 audio ended 6 secs before the video.

This agrees with what you are seeing.

I only use WAV files for importing into VPX?VDL following finding this problem and another random issue with MP3 files and transitions, what I call the Brrrr (say it fast rolling the r's) effect.

John, You nailed it. I exported the song (an MP4 H264 and AAC) to WAV (ironically using VDL) then used that WAV with my footage and it came out perfectly with the 3060. It would appear that Magix is having trouble combining high-res video (at least this sort of video) with audio other than WAVs on the NVidia.

Thanks Andy, for an old fella, you're quite the investigator! I'll consider rolling back to that 577 driver.

Cheers Ray.

We are moving into the Brrrr season down here.
