I am cutting a video for a school project at the moment, but now I have a big problem. The video sticks all the time. I couldn't even watch the video because it'S like watching a gallery with a lot of pictures. But in the beginning, it works a lot to click on "Render". But now nothing makes it better.
You've not provided any information about your Premiere Elements version, your computer or you video files. My initial guess is that you are editing complex video files with a weaker computer. It might also be that your project settings don't match you source footage.
If you want to pursue this please provide more information.
