Render Not Using GPU

Phil-MJr. wrote on 1/27/2020, 2:12 AM

I have had trouble rendering with RTX-2070. Sometimes black frames are rendered between the footage. These problems are more likely to occur when rendering in Ultra HD or when an event has effects, such as Boris Effects applied. But if I specify the graphics card, it does attempt to render with it. After I select Render Aa, I select a GPU template or customize one. Should work.

While checking a few of the many nvenc variations to see which gave the highest quality (using ffmpeg for SSIM & PSNR) I made this small table. It also indicates the combination of settings that causes either a zero byte file or a file with no video stream, just two audio streams, marked as “fail”. Is it possible @alderny you are using one of the “fail” combinations?

Source & output testing was all done in UHD at 135/100 data rate.

Lower data rates might not cause the fail in UHD if less than data rate of 135/100.

I've highlighted the table in green to show the best quality, and the red box in templates indicates preset and RC mode for best quality.

@alderny
Which exact driver do you use for your Nvidia card?
And can you give a screenshot of your settings in Options/Preferences/File I/O?

Driver version 441.66, which is the very latest (as of today). Driver type is DCH.

When using the NV Encoder mode VP17 returns this error:

These are the render template settings that gave this error. Other settings also give this error:

Strange, this error.
On my desktop I use almost the same GPU with that driver and it renderfast and fine to FHD 50p and UHD 50p with the Nvenc and Magix HEVC and AVC codecs.
GPU use upto 40-50% and with a much more powerfull CPU.

Field Order: "Upper field first". Is that really interlaced video?

Yes, my source video from my camera is 25fps interlaced, upper field first. The output is for Blu-ray, where the PAL standard is I believe 50i (50 fields per second, which is 25 frames per second interlaced).

I cannot find such a custom template with NVENC, so I think you used an (older?) customized template .
Maybe it is better to use the default template for BR (only Magix Mainconcept) or make a new customized template with NVENC like this one

It gives me such a file

Thank you @j-v, I didn't realise that there are now templates specifically for NVidia encoding. I took the templates I used in Movie Studio 16, to Pro 16 and then Pro 17. I have now tried one of the NVIDIA NVENC templates, and it works, although the GPU is still at between 12% and 25% (previously 4%), and the CPU has dropped to about 70% (previously 90% to 100%). Rendering is now faster, but no more than about 2 times.

I had to renew all my old and ever used custom templates for new ones, it was a confirmed kind of bug. I don't know if that is still needed, but for you it helped.

I'm having the same issue where my GPU doesn't go above 5% but my CPU stays around 30% as well. I got an i9-9900k and an RTX-2080. Using almost the same render settings j-v posted above. I never had this issue in VP16. I have tried so many things but rendering in VP17 is just a mess for me. I had a benchmark test where VP16 rendered the test in 56 sec and VP17 took 4min07sec. HW Acc. is enabled as well.

@Sniping117
If you don't give information it has no sense to tell us your problems because nobody here on this userforum can help you without the needed info.

I cannot find an NVENC encoder template that uses interlaced video, which can be used by DVD Architect. If I change one of the provided templates to interlaced, then it fails to render. Does anyone have any ideas about this?

I have this exact same problem with my new 3080ti all my drivers are updated using studio drivers currently but I use Movie Studio 17 platinum. If I try and use NV Encoder, it will fail within the first 10 percent of rendering. If I use Mainconcept AVC it renders so damn slow but will finish the render at least. After using 3 versions of Vegas (Pro 12, 14, and MS17 Plat) I think I'm ready to move on and try other things. These programs have become nothing but a nightmare.

I'm not familiar with Movie Studio but did use Vegas Pro 15-19 with NVENC. In version pre-19 I found you needed to set dynamic ram preview to 0MB to get renders to be reliable. In 19 it has worked for me without that workaround. The upgrade price to Vegas Edit 19 is pretty good as well.

@alderny You might try the Sony AVC/MVC templates some of which are dvdarch bluray specific. I know they always work for me with an amd gpu if I choose "Use Legacy GPU rendering" under deprecated features. That option causes an extra drop-down to appear in the Sony render templates to "render using GPU if available". Might work with your Nvidia gpu or your Intel cpu + 4600 igpu. You can do a quick check by selecting the template's System tab and clicking on Check GPU. If the Sony template cannot use your gpu or igpu, it'll tell you so.

Just tried it with Vegas 17 build 455 on my laptop which has an Nvidia gpu and an Intel cpu + hd630 igpu and it worked displaying that it will use qsv when I clicked on Check GPU. I also have Intel selected in the I/O preferences and "Enable Intel encoding and decoding (when available)" in General preferences. I also have Intel gpu drivers installed and "Integrated Graphics" selected in the Nvidia Control Panel 3D settings. Oddly, the Sony template in Vegas 19 told me "No GPU available" on the same machine with the same settings.

DVD Architect takes MPEG-2 video streams for DVDs, not AVC. The only interlaced AVC for BluRay you will find is AVCHD, and not at all with machine encoders, I'm pretty sure.
