Exporting Black Video (ALREADY installed a new driver)

Thank you for taking your time to read this and help me 🙂 

 

So, there was a notification telling me that I have to install a driver, which I did. But when I export the video, it is PITCH BLACK. The audio is there, but not the video. Also, when I play it back before exporting, the video also disappears when I pause it and only comes back again when I play it. Everything works just fine when rendering with software only, but all of the above mentioned problems occurs when rendering with (CUDA) GPU Acceleration. 

 

If the driver isn't compatible or applicable (the one I downloaded) then a notification should pop up, no? 

 

I also tried https://www.youtube.com/watch?v=VhWeMPt3SQc
but it didn't work.

 

Any suggestions?

 

Thank you again.

Please use the free MediaInfo and post a screenshot the properties of your media in tree view:

Many users are having issues with VFR. If the file is variable frame rate, use Hand brake to convert to constant frame rate:

    What happens if you save and close the project and then re-start the computer and try again?

     

    If nothing, add more info such as specific version of Premiere Pro, specific graphic card, specific graphic card driver and specific info about the project/media/resolution and Export Settings.

      Ok, I restarted the laptop, but the problem is still not solved. 

       

      Reminder: it is also black BEFORE exporting. The video only appears when playing back. 

       

      Premiere pro 14.0

      Graphic Card: GeForce GTX 1650, driver version 456.38, driver type DCH

      Project/Media/Resolution (mp4, 1280*720, frame rate 30, Video Codec H.264 4:2:0) A video from Iphone. 

      Export Setting: Format H.264, 1920*1080, 29.97 fps, progressive, hardware encoding, VBR 1 pass, target 16 Mbps AAC...

        The only thing that sticks out is the odd frame rate on the source sequence caused by the fact that the source footage is variable frame rate, something Premiere Pro dislikes.

         

        Go to Sequence > Sequence Settings and change the Frame Rate from 29.438 to 30 and click OK. This may be the solution but i doubt it.

         

        If it still fails, it would be intersesting to know if simply disabling the Adjustement Layer on V2 solves it. Or, go to File > Project Settings > General and set the Renderer to Mercury Playback Engine CPU (Software Only). If it still fails installing this driver may help: 456.74

         

        If you start a brand new project, do the same thing happen there as well?
