Some issues with strong PC

Hi, I have got a pretty stong PC i7-4790k + GTX 1080 and I have some issues with the software.

1) If I just click on a specific time frame on the timeline the program monitor is black, when it should be the specific frame I am currently on, some people say to switch the renderer but the other one is very laggy and I can't work with it and If I do some scaling in the first renderer in the other one the scaling will be way off....

2) After I render my clips I can't watch them at all, if I click on the start button the program monitor is staright BLACK.

 

I am very new to Premiere Pro I am actually on my trial and its very very disappointing 😞 

Would like to get some help, thx 🙂

Correct answer RjL190365

Is there a way to exports all the clips I have already cut in my edit? So I dont need to cut them again 


You have no choice, in this case. You will have to re-cut no matter what. No NLE can handle your intended source well, if at all.

 

And since you had converted that video the wrong way (leaving in VFR when you don't want to), that will only excabate the problem. All exports from your converted video will drift way out of sync on the audio and the video tracks no matter what. And such an out-of-sync export cannot be fixed correctly, if at all.

I am sorry to tell you this, but that i7-4790K is now a weakling CPU by today's mainstream standards: It has only 4 cores and 8 threads, compared to a minimum of 6 newer, better-performing cores for even today's economical desktop PC. In addition, it is too old for use with any newer version of Premiere Pro. And not only that, but the GTX 1080 is now outdated as well.

 

All that results in relatively poor performance compared to even today's economical PCs, especially for video editing. No wonder why Nvidia skipped Volta and waited for Turing to release new consumer GPUs, because Volta would have been more of the same type of lousy performance when forced to render under pressure (like all other Nvidia and AMD GPUs which come before it).

 

In other words, future proofing doesn't exist any more. Especially since today's upper-mainstream CPUs now have at least 8 cores and 8 to 16 threads, compared to your CPU that's now six years old (and your CPU platform being seven years old) at this point.

 

And had you run the Puget Systems' PugetBench for Premiere Pro benchmark, you would have been embarrassed with an overall score that's barely half of what newer PCs in the same price range as what you paid for the sum of your system's parts.

    Alright... pretty sad but I get what you are saying...

    What to do now to fix it so I can end this b-roll editing

    Since all smartphones record only in VFR (Variable Frame Rate), and that older CPUs do not do a very good job of handling H.264 video (and an especially poor job of handling HEVC video), your only choice at this point is to transcode using Handbrake to a CFR frame rate (use one of the "Production" presets when you use Handbrake to transcode so as not to retain the VFR feature), and then transcode that intermediate file using Media Encoder to a more editing-friendly codec such as ProRes 422.

     

    And that is all in part because NLEs, especially Premiere Pro, choke on VFR video content. When exporting such content, you'll find that the video and audio all too often goes out of sync - and sometimes way out of sync.

      The type of media you work with has a big impact on the performance of your computer and editing software. Can you tell us more about the type of footage that you're working with? You can right click and choose Properties (inside of Premiere) or a more thorough place to find a lot of info is with the Media Info app in the tree view.

      Other things it may be: Make sure your GPU is updated.

      Other question: Are you using dual display adapters/graphics cards?

      Footage taken with my iPhone 10's Max that were converted to MP4 

       

      My GPU drivers are up to date and I do have two monitors working simultaneously

      The tree view of that window provides the good stuff 😉

       

      iPhone footage is going to suffer from Variable Framerate as well as not being in a very good codec for editing. When you say it was converted to mp4? What do you mean by that?

       

      If you've already transcoded your footage and you're working with h264, it's not a great editing codec but you shouldn't be seeing black 😐 Still, if you're getting black screens with the hardware renderer and it gets fixed when you turn it to software only, I think that again leans toward a GPU-related problem.
