Nvidia Support

I could cry :-(

One of the most exciting features of Magix Pro X10 that was advertised was the "NEW NVidia GPU Export" feature. So over the weekend, I finally splashed out on a high-end PCs with an NVidia GeForce 1080 card, thinking this would reduce the time I spend rendering my videos. Having just spent the evening installing the software and rolling forward through the updates to get myself to the latest version, I was excited when I finally got to the point where I might just experience the power of the new PC.

Alas, it wasn't to be.

My 4 year old laptops renders videos faster, as I can't seem to get the hardware acceleration to work. I select the option in the video export settings and all looks good - I check the settings and can see the words "hardware encoding" in the MPEG-4 export settings window. So, I click OK and it enters snail mode and the title bar of the export windows now shows "Mixing down...(no hardware encoding)".

Have I wasted my money?

Please can someone tell me how to enable this "NEW NVidia GPU Export" functionality that enticed me to go and spend a lot of money?

@ArnieB

We need more information about the new PC:

Please read this topic and put the following information in your profile signature so we do not have to ask for it:

Computer specification - processor make/model, graphics card or chipset make/model, audio card or chipset make/model, RAM, hard drive configuration and sizes?
Windows version and is it up to date? Press and hold down the Windows key and the R key - in the dialog that opens type in winver and press enter.
Software full name and version number - as found under Help, About . . .

Also some details of what is on the timeline ie source video resolution and format - MediaInfo analysis data of one of the clips will help - copy the results from the Text view in MediaInfo - including effects, transitions etc - a screen shot would help.

Screenshots (cropped to show required information) of the following may help Program settings, Import/Export tab and Export settings dialog.

There's a fair bit of information there, but I will start adding it to my signature. I have just done the Winver command and it's 1709 (OS Build 16299.15) I had assumed it was the latest version (1803) as it was a brand new PC. After reading through the other posts on here and my own experience on my laptop, I am slightly reluctant to upgrade to 1803 (when I did that on my laptop I lost all sound on MP4 files and it took me almost two weeks before I got back up and running).

Thank you

As far as I can work out from forum feedback - in VPX10 the new NVENC (Nvidia encoding) only works with H265 (HEVC) encoding, and possibly only in conjunction with the Main Concept encoder ( which is a separate purchase).

With H264 encoding you should get HW encoding on your Intel Integrated GPU if you have a recent Intel processor and it's GPU shows up in device manager along with your Nvidia GPU, but we need some more details as requested by JohnEB.

That is indeed interesting and I have now stopped crying. Thank you. I selected HEVC output and the encoding speed was clearly benefitting from the GPU as it ran about 20x fasterr. So maybe the problem is fixed. When I tested things yesterday, I was selecting <File><Export move> <Video as MPEG-4> as this was the option that I always used on my old laptop. Interestingly, I had previously tried to export as HEVC from my laptop and it renders at about 2 frames per second but I could get reasonably good hardware encoding speed if I selected MPEG-4 on my laptop.

Can anyone confirm if there is any difference in playback compatibility between videos encoded with HEVC compared with H.264. I.e., if I start using HEVC to create the output files, I can see that the file type is MP4, which is what I produce as default, but is there any risk that an MP4 created this way might not play in circumstances that an MP4 produced using the H.264 codec would?

Apologies if that is a silly question, but I clearly have a bit of learning to do about HEVC/H.265

Thank you

Absolutely, there are only hardware devices like TV's produced in the last year or so that can play these files, so you are limited to computers with software players of similarly recent vintage.

From the information in your Sig you should be able to activate the iGPU in the i7 8700 to HW encode your H.264 with the Intel (default) encoder in VPX
