I am currently experiencing another strange bug since running the update to the latest version of PPCC2018. When I go to encode within Premiere I get "Software only" displayed in the summary area and the encoding settings within this panel are greyed out, as can be seen in the attached image. The encode was taking forever so I stopped it and went and checked and CUDA GPU acceleration had been changed to software only in the Project Settings, which I didn't do myself. I changed this back Mercury GPU Playback and the encode went a lot faster, as fast as I would expect when using GPU.
Now my problem is, whatever project I open I get "Software only" displayed in the summary, even though CUDA is enabled in both PP as well as Media Encoder. The project encodes SEEM to be going at GPU speeds but whatever I do the software only message remains. I have noticed that if I change the codec from H264 to MPEG2 for example, the software only message disappears. I am not now 100% sure if my CUDA acceleration is working correctly as the software only message is on every project I open and go to encode within Premiere. If I select to Queue the encode and use Media Encoder, the drop down menu at the bottom of the encode list says CUDA.
Has anyone else been experiencing this?
I have so far:
1. Re-installed PP CC 2018 latest update
2. Installed latest graphics cards drivers as a clean install
3. Tried opening a new project, saving that as CUDA enabled
But nothing has fixed this...
Windows 7 Professional x64
Nvidia Quadro K5200
PP CC 2018 fully up to date
Any advice greatly appreciated!
I have exactly the same problem! I have been on the phone to Adobe today and we tried a fresh install of Premiere Pro CC as well as what you have tried to no avail.
This is a serious problem Adobe, you need to fix this quickly!
Ok it's not just me then clearly! The fact that Adobe support were going through fix tasks with you would suggest that this isn't normal behaviour due to H264 no longer being supported...I am off to try the suggested patches below and will report back!
Me too! See you on the other side...
Let me know how you get on!
The CUDA toolkit installs went fine but have rolled back my driver to an earlier version, so I need to update that (again). I've described my render task in another post but basically, the output summary stated "Software Only" but the GPU was definitely being used during the output. The load on my card reached about 90% and the temperature went up to 75 degrees C. The moment the output was finished the load dropped to zero and liquid-cooling has brought the temp back to 44 degrees C. I think the card was busy and the output summary is misleading. What do others think of the rendering time for the job described? I have a ten-core i7 processor, 64GB of RAM and a GTX1080i graphics card. I need to know Premiere Pro is putting all that investment to good use!
Please let me know the bitrate settings you have chosen to encode the project.
Also, let me know the contents of the projects like Video file formats, sequence settings, images, effects (third party or Premiere Pro's etc.)
Also, can you check export in VBR 1 pass and let me know the results.
Hi Vinay. I'll try this too when I am back at my PC. Thanks.
Hi again. My previous encoding settings when experiencing the issue were:
H264 VBR 2 Pass 15 target 20 max 1920 x 1080p 25p Progressive. Audio 224
Timeline was a mixture of MTS files from an FS7, MTS files from a C100 MK2, native and third party effects and some JPG image files.
Let me know the results when you try encoding in VBR pass 1.
Hi Vinay, just tested with 1 pass VBR, no different, same problem. I have also installed the CUDA toolkit and all patches and rebooted my machine. Thanks
I've finished for the day, so I'll pick this up when I'm back to editing. We seem to have made some progress with VBR Pass 2 not available for some people and that being acknowledged as a shortcoming of the app. What do we think about the evidence I've seen that my GPU is working when the output summary says it isn't? Could that be happening?
Great info on Bill Gehrke's work. Thanks Stan!
I think you might be right Martyn. It FEELS like a display bug...
Hello there - I found this thread after a little googleing. My copy of premier 2018 CC also said "software only" in the export settings for h.264 after the latest update.
I can confirm my GPU is being used whilst exporting, despite the confusing message.
I was rendering a 4k video a moment ago, and i could see around 20% load max on the gpu using Task manager in Windows.
I also see the Software only setting in the export dialog.
Using Windows 10 x64, dual xeon E5 2640-v4 10 core cpu's, 128 gig ram and a Pny Quadro p5000 card.
On a good note, now PPro managed to export my video from my gps, 100+ 1 min long clips it failed earlier for some reason,
just regular HD video.
In addition to responding to Vinay's questions, I suggest posting the general performance question in the hardware forum:
See Bill Gehrke's testing method:
He is active on the hardware forum. Use the submit button on his site to get the results to him. Don't just post them on the hardware forum.
I have the same issue on Mac OS.
Is it due to latest update of Adobe not supporting H264 QT Legacy?
If so, might have to render ProRes then flip to H264?
I don't like how the CUDA tool replaces the existing video driver. What's all that about?
I'm installing just the CUDA toolkit, my driver is more up to date than what's in the package. Using the custom install option
Too late for me, so I'll grab the latest driver again (only did this yesterday). Do you reckon I need to recalibrate my display again? Not sure how drivers affect colour rendition.
OK, Vinay. Did that. Now exporting to H264 mp4 again and I'm still seeing "Software Only" in the output summary. However, in my system monitoring I'm seeing 84% load on my GPU and steadily rising GPU temperature with the fan speed creeping up. I'm outputting a 42 minute sequence of 4k clips to 720p with a target bitrate of 6Mbps. It will take 16 minutes to complete.
Not sure if this is helpful, but when exporting to some other formats the output info does not show "Software Only" - DNxHD, for example.
This afternoon I've been outputting a multi-camera job from AVCHD footage (.MTS files). For this project I haven't used any Lumetri effects at all. Outputting to H.264 mp4 I'm seeing 'software only' in the summary and according to my hardware monitor my GPU is NOT being used. It has taken 15 minutes to output a 50-minute sequence with three separate video tracks.
