Cutting unnecessary scenes from a recorded video is routine work in video editing.

3. Why Cutting or Trimming Videos Reduce Video Quality?

When you cut, trim or edit the video in the post-production, video editing tools will decode the videos first, and then re-encode them during the process of rendering. While doing so, if the codec you choose has a high compression ratio, it will inevitably reduce the size of the clip, and will thus remove any additional information that the footage contains. As a result, every time you cut video or trim it, you still get degraded picture quality even if not quite significant.
