Have you set Windows Graphics settings for VPX to Power Saving?

It should be on that setting. Windows / Settings / Graphics settings / choose an app.

Ray.

 

Thank you very much for your quick response.

I did what you suggested, but it didn't work. when exporting, the window caption says "Mixing DOWN (no hardware encoding...)

Please, can anybody confirm that VPX can use the nVidia GTX 970 to accelerate the encoding process? Maybe i just can't get it working because acceleration is not supported on this card.

I have tried enabling the integrated graphics card alongside the nVidia, and it seems to have improved. Now, a 5 minutes long project renders in "just" 9 minutes. However, The very same project in Filmora only takes 1 minute and 44 seconds.

@GarciaFigueres

Have you gone to the program settings page and set up your Intel and nvidia GPUs?

Are you using Direct 3D rendering and have both GPUs showing?

Ray.

Ray.

Yes. These are my current settings:

Just FYI, I've also tried HitFilm Express and it's as fast rendering as Filmora.

Again, thanks for your help.🙌

@GarciaFigueres

Hi.

That setting is incorrect. It should be the same as mine. The Intel GPU should be at the top and the nvidia in the middle boxes.

@GarciaFigueres

Please note that VPX can only perform hardware rendering on a discreet Nvidia graphics card when exporting to HEVC (h.265) codec with HEVC material in the project. Magix state GTX1050 or higher / later, but some members have found the GTX9xx series also work. All HWA rendering of H.264 is performed on the Intel iGPU.

Without any knowledge of the makeup of you timeline and the details of your clip's files it is not possible to say whether your export time is reasonable with the older 4th generation Intel graphics, but it does seem a little slow.

One thing that can speed up export by 30% or more is to select the Nvidia card in the "Video Mode" > second box where you have the Intel 4600 selected. Don't ask me why but it works.

Also do not select "Calculate Video effects on GPU" in the MPEG Export window as this can slow down rendering.

A screen shot of your Task manager Performance window with the Intel (GPU0) highlighted during export might show us more about what is going on.

@CubeAce

I can't select anything on the top box, since it's disabled.

@Scenestealer

I think the problem is what you commented on the HEVC codec.

Thank you very much, both of you.

@GarciaFigueres

Hi.

If the selection is disabled, then the Intel GPU may be disabled in the bios. Are you only running one monitor?

Ray.

@CubeAce

Yes. I only have one monitor. However, I made sure the Intel GPU is enabled in the BIOS.

@GarciaFigueres @Scenestealer

Hi.

In settings / graphics settings have you added Graphics performance preference to Power Saving?

It must be set to Power Saving.

Also you may need to add a physical Ghost header to that GPUs output socket for it to activate.

Most of us are using two monitors. It could be why Peter's suggestion of selecting nvidia over the Intel GPU may work.

Ray.

@CubeAce

Hi Ray.

Yes, I set the Graphics Performance as you said (I did that the first time you mentioned it).

I don't think it's worth the time trying to solve this. I mean, it's not been a big investment, and it requires too much hassle to make it work (if I ever get it working...).

It's kind of a pity for me, because I really wanted to use VPX, but I don't wish to bother you anymore. I'll have a look at another options 🙂

I am very grateful for the effort you have put into this. Thank you, thank you very much.

@GarciaFigueres

We are happy to try to help, it's no bother.

I'm surprised you are finding Filmora faster though as my son uses the same model of 4K camera I have and he uses Filmora and his export times are much longer than mine for a similar length of video.

Hence my interest.

Ray.

@CubeAce

Probably it has more to do with my PC settings and my lack of knowledge in video editing. However, I'll try to record some videos to show Filmora vs VPX performance. 🙂

@CubeAce @GarciaFigueres

Also you may need to add a physical Ghost header to that GPUs output socket for it to activate.

I do not think the choice of GPU's would come up in the Program Settings > Video mode if the iGPU was not active.

Most of us are using two monitors. It could be why Peter's suggestion of selecting nvidia over the Intel GPU may work.

No, I suggested that because several of us have found that if the Nvidia card is chosen in the Video Mode, then it shortens the rendering time during export.

Hi again.

I've uploaded a video comparing both programs. I must say that I checked again all of the settings you suggested before, and the rendering times have decreased. Still, Filmora is roughly 3 times faster than VPX.

This is the link to the video:

Again, thank you both.

@GarciaFigueres @Scenestealer

Then if you are happy with the quality of the output of Filmora you should go with that program.

I must say, your render time did seem very slow for basically a straight render.

Hi John.

If both GPUs are enabled why is nothing selectable in the top dialogue box, or is that for a second monitor only?

Ray.

@GarciaFigueres

You are testing with 1 video clip that looks like a screen capture of a game, without us knowing the details of the video clip, and exporting with slightly different parameters in 2 programs.

Does the video clip have variable frame rate?

In Filmora, you are exporting to 60fps, in VPX 59.94fps. In VPX, you are modifying the optimized settings to be what may be similar settings in Filmora, but we can't be sure.

I suggest that you post the video clip to DropBox or another file exchange so that others here can look at it and try exporting to see if they get the same result.

VPX is a lot more than just exporting.

John CB

Hi @browj2, thanks for joining the discussion.

You can get the source video clip from this Onedrive link.

Please keep in mind that I'm not an expert in video editing at all. On the contrary, I'm just trying to learn new things. There are lots of concepts that I still don't know and, as I said before, probably all of this is because of a bad PC settings which, I must admit, was not built for video processing.

Great! It seems that you've finally found the problem. Still, there are some things that I still need some help with, if you don't mind:

1. How/Where do you see that the clip has variable frame rate? With a FPS counter or something like that?

2. What does "MEP" stands for?

3. I've always used NVidia Shadowplay to capture gameplay, but it seems there's no way to disable de VBR. Can anyone suggest any other software to accomplish this? I've read about OBS, but it seems it takes a lot of system resources compared to Shadowplay.

@GarciaFigueres

1. Use MediaInfo to see the details of the file.

2. MEP = Movie Edit Pro

3. I don't capture gameplay or use OBS, so I'll leave that to others.

Just got back from a walk. Downloading the file now. However, my computer is old and definitely not a reference.

John CB

@GarciaFigueres

Hi Garcia.

Variable bit rate is fine. Variable frame rate is not. OBS studio is a free screen recorder that can produce a Constant frame rate video file from game play.

The Media Information from your supplied file looks like this.

As you can see it gives us a lot of information about the file and possible problems it could throw up. It was a good catch from John to realise it was a possible game play video.

OBS studio can give good results with small files at 1080p

Here is similar file information from an OBS screen capture without the need to make variable frame rate files.

The second file (mine) would encode much quicker.

Movie Edit Pro is the next editor down in the Magix line up of video editors. Not as powerful as VPX but shares a lot of it's components. There are three versions in order of ability low to high MEP Pro. MEP Plus, and MEP Premium. After that it is VPX, Video Pro X.

I am currently running MEP Premium and VPX.
