Dear Video Editor Experts!

I got today DaVinci Resolve and unfortunately jerk the reproduced videos. Ansich I have a new notebook with i7-8550U, 8GB ram, SSD and a RX550 with 2gb memory. Is that too little for 1080 HD video editing?

To answer your question missing important information!

Which project settings do you use?

What video properties does your video to edit have?

Mi

Thanks for your quick reply! The video to be edited is a MOV file from an iphone 6s (68.5 MB, 1920x1080, approximately 60 frames per second). Project settings I left as they were after installation (ie 1920x1080 resolution; square; 60 frames per second; SDI: dual link; data level: video; video bit depth: 10 bit; monitor s.: bilinear; opt. Media resolution: choose automatically; opt Media Format: DNxHR HQX (same as Render Chache Format); enable background caching after 5 seconds and automatically cache fusion effects in user mode; frame interpolation - retime process: nearest; motion estimation mode: std. Faster; motion range: medium)
Unfortunately, I'm still new to the field - I was recommended the program and I wanted to get familiar with learning by doing, but then I failed here: - /

Well, it can't work that way. You have to learn how your project settings look like. You really need to know the video properties of your video.

(68.5 MB, 1920x1080, about 60 frames per second). Of course that's not enough. All features can be viewed using the VLC player or MediaInfo. These properties are also your project settings.

Accordingly, you must change the project settings.

Here the program is well explained in German: https://www.film-tv-video.de/equipment/2015/11/12/praxistest-davinci-resolve-12-fur-editing-und-grading/

But you will have problems with the preview despite the correct settings, because unfortunately your PC is too slow. 8GB RAM is not enough, it should be at least 16GB RAM. Your graphics card is a bit weak for Resolve, but above all, the 60fps will bring your PC to its knees. With 30fps it will be much better.

A preview is there to get an overview of the selected effects and cuts. It is absolutely not necessary that a preview runs smoothly, the more intense the cuts, the more complex the effects, the shakier it gets. Only a render process then generates a file that can be stored smoothly.

Ha

Yes, that is a bit too little, at least for smooth. DaVinci uses as far as I know, mainly the processor and there comes the small power-saving ULV in your notebook pretty much gasp.
For a smooth cut you need a real workstation and even there can be a few frames are skipped, depending on how complex the cut is.
But should not be tragic, because an editing program is not meant to watch the videos. You do that later, when they're outraged.

Thank you very much for the detailed and helpful answer! Too bad that the notebook can't deliver 100% of that performance - I thought that HD video editing would not take up that much. But maybe I can upgrade it once. I definitely do that with the Project Settings and the explanation today, that helps me a lot!

It really stopped in 1.5 seconds, so it was barely recognizable as a video. Meanwhile, I'm working on the improvements of herja and I screw a bit on the settings of my graphics card. It does not have to be smooth, but I should be able to work reasonably well with it.

A pity, I thought that would fit! I do not look right with the many processor versions. Maybe I should really get a workstation. But yes, right, smoothly I can't look at DaVinci.
