Works with any frame rate 25 to 60fps

Hello, I bought the template and unfortunately the problem I feared is there. With a 25fps timeline, the video is not smooth. If you go frame by frame, you can see that some frames are duplicates or are skipped. My guess is that it’s because the “Media Placeholder” timeline is at 60fps. 60fps, 30fps, 29.97fps there will be no problems, but with 25fps there is a problem, the video is not smooth. That’s exactly why I asked. Is there a solution for this? Maybe I missed something as to why this error occurs? Thank you for your help!

Any help?
