nvenc h264 exports result in glitches and image errors

[noafilm]

It just keeps on coming, nvenc mp4 exports now result in glitches and pixelation errors in the image, does not happen when I use the tmpgenc avc plugin for mp4 exports or just the edius own exporter without nvenc but then the graphics card is not being used. It can't be the graphics card or drivers (latest installed) as resolve studio 17 leans 100% on the gpu for export and I don't have a issue there.


pcspecs: amd5950x, rtx3060ti, win10pro, edius x pro 10.31.8487

Which version of Edius are you using? What is the resolution and frame rate of the project? What codec/format are the clips on the timeline?

Does render and add to timeline help before exporting to MP4 using the NVENC?

[noafilm]

Edius version is mentioned in my post, I already went back to an older image/edius version so can't do any testing, don't think it matters what resolution or codec I used as it just is not supposed to happen, the errors I saw looked like pixelation appearing randomly in the image, it actually is the second time I have noticed it, this time it appeared on videofiles from my panasonic cameras and last time on images from a phone, last time however I thought it might have to do with the variable framerate phones have as it only appeared once but since my panasonic mov and mp4 videofiles where affected too it has to be some edius/gpu related issue.
Currently my nvenc exports work as expected and hope they continue to do as it's quite a timesaver when the GPU is assisting.

Hi

I made a little drama with my video club during COVID, in 2021, and I filmed my self against green screen (I played an unscrupulous music producer who had run off with all a music band's royalties) so everybody sent me clips to use (the band members). It was a challenging video as the interviewer did the links for the other band members in Hawaii and against the same room backdrop, as one of the band members, and I had wanted him to use a green screen. So I had to use the mask tool track him and create appropriate backgrounds to match the room style for the other band members interviewed in the UK, so he looked like he wasn't in the apartment in Hawaii. Also he had left his shirt undone at stomach level so that had to be filled with a colour that matched the shirt, to cover up the bare skin.

Fix it in post! Yeah right! Grrr

There was one part of a clip that was iPhone 12 footage that came in from Hawaii. The actor, whose son was the interviewer who lived in Hawaii leaned forward to hand over some original song script handwritten papers to the interviewer as proof she had written the song, and at that moment it all fell apart and pixelated looking at the MP4 encode, however in my case I had to use the TMPGEnc plugin to get around it as the software encoder also got it wrong.

I tried render and add to timeline just for that clip as HQX and that didn't help.

The HQX render was perfect.

There do seem to be a set of circumstances that cause the problem.

I did report it to support but it was treated as an isolated incident.

The project was UHD 50p

The iPhone clip with that paper handover is here and you only need the first part.

I also have the avc TMPGEnc plugin which did not cause pixelation, I only keep having issues with Edius and I"m sure they are all related to the way Edius uses the GPU, not a single issue however with Resolve so it's not a hardware problem, it's a edius issue, same as with that black frame issue I had in the past, again, only edius with black frames on export, not resolve on the same pc.

try the following:

Under Nvidia Control panel:
- Change PhysX setting from autoselect to RTX3060Ti
- Under manage 3D settings set the power management mode to high performance.
- Under manage 3D settings, set open GL rendering GPU to RTX 3060Ti

Thx for the tips, time will tell if these have any effect on these glitches.

Seems like you’ve been having a number of issues recently. Just give GV time to get things right.

[createmedia]

I have tested my naughty clip and it is now working just fine in both the software and the hardware encoder.

I have Anton's settings selected.

However, Edius X latest is very happy to play (system 4) the software encoded clip (50p UHD HEVC) with full buffer but will not play the NVidia encoded clip in real time at any resolution. (No Quicksync)

What's the difference?

Ah I can only play CBR files without Quicksync and CBR is grayed out in the NVidia encoder.

Those were HEVC files

Tried with H264/AVC also now OK converted UHD to HD and checked playback full buffer no pixelation.

With the last update yes, before that things seemed to be running fine.

While everything seemed to be running fine again after I switched to an older version of edius I exported a finished edit today and watched it on a older Samsung HD tv, the film was full of pixelation errors...BUT when I watched the exported film on my pc monitor there where no errors!

It only happens if I choose Edius h264 Nvenc encoder, if I choose edius own exporter (without nvenc) it looks fine on tv but the quality of that encoder is poor, nvenc gives better results but now result in bad pixelation errors appearing randomly in the film but only on TV. I tried exporting a hqxavi in Resolve studio using the nvidia option and that looks fine. If I use the tmpgenc avc plugin in edius it also looks fine on tv.

So I decide to update to the latest version of edius again hoping that would solve the problem but again wishful thinking. Edius now also randomly crashes on startup, after that it starts up and functions normally.

To make matters worse, the black frame issue has returned!!! Only this time it's a all new pc, new OS, new hardware, all drivers up to date, all edius exclusions made in firewall and virusscan, NOTHING from my old pc that has been transferred and here it is again, the dreaded black frame. Since my old pc is out of the equation I can only conclude it is a EDIUS issue, nothing else, maybe Edius has a issue with my Panasonic camera videofiles, who knows.

I can export and deliver to my clients but it's again a large timeconsuming pain since I first have to export to a 4K hqxavi, locate black frames using a ffmpeg script, bring the file back into edius, replace black frames with native footage, export the hqxavi to hqxavi again and use that file in resolve studio to do the final HD and 4K mp4 exports, I tried handbrake but for a odd reason nvenc exports are very slow with HQXAVI footage, resolve studio however eats HQXAVI for breakfast, it flies through a nvidia mp4 export using my rtx3060ti card.

So, here I am again, after have wasted lots money and time to get edius up and running like it should to find out it's not working, for those who want to help troubleshoot, don't, also don't tell me you don't have any problems, I know you all mean well but I don't want to waste anyone's time knowing it doesn't help and I know, I tried for years, saying you don't have any issue doesn't help either and while at first one would expect it was my pc that is also not the case since the new pc is showing the same problems.

So today I decided to switch to Resolve Studio permanently which I have on my pc since version 16, I only scratched the surface of the capabilities of that program and used it only for a few small personal projects, I held back from switching because I enjoyed editing with Edius too much when things seemed to be working fine after my pc upgrade. But now I’m back to square one and I’m just sooo tired of trying to troubleshoot all these Edius issues I have been experiencing the past years.
I still need to use edius in the coming months using it's timeconsuming workaround to get my films to my clients as I have some busy months ahead and I'm not nearly as proficient in resolve as I am in Edius to just switch today. I need a longer transition period before I feel confident enough to drop Edius completely so probably am looking at the end of this year to make that happen.

I want to thank every user here that has made an effort to help out trying to solve issues, it was much appreciated and I wish every user a trouble free Edius experience. J

I did much the same but for different reasons. Still use EDIUS 9 but for interlaced stuff I need to do but most is now Resolve. Even got a Studio Max. My first Apple product !! Everything else in the house is Windows or Android.

Once you find your most used functions, Resolve does start making more sense. It may take more time than you’d prefer, getting as familiar with it as you are with Edius and editing as fast. It’s also less than perfect when you make a major change to your workflow, especially when your workflow is your job and income and “learning on the job” is also problematic.

However, consider this. How much downtime have you had with Edius? And regardless of your familiarity with it, it doesn’t make up for the lost time and money. At least with Resolve and in spite of the fact that it will take a bit of time to get fully up to speed. You’ll be putting all that time to better use and moving forward with a far better supported NLE and you’ll also start feeling a confidence in your workflow that you’ve not had for some time.

I know it’s all but impossible to migrate your unfinished Edius projects over to Resolve and any workaround to that end would probably be more hassle than it’s worth. But just keep an eye on that light at the end of the tunnel and remind yourself that once you’ve got your legacy projects finished, you’ll be in a much better position moving forward. Plus, you don’t need me to remind you that there’s a whole new world of post functions to look forward to in Resolve. Weather you need many of Resolves functions is one thing but just knowing that there’s a lot of extra functionality that no other NLE has, is a very comforting thought.

Anyway, I wish you a speedy transition and in a few months time you’ll feel a lot further away than a few months past the headaches you’ve had.

Lookslike your problem is not going away as where it was on starting i appericiate your efforts if i were on your place i had give up at very early stage.
