Site crashes when uploading a video

My server runs on an AMD Athlon 3000G CPU with 6GB of RAM. It is not a high-performance server, but it is not extremely low-end either. However, after installing the Image Placeholders plugin, my site crashes whenever I upload a video.

After investigating, I found that ffmpeg runs during video uploads, consuming all available resources. I later discovered that this happens because the plugin tries to analyze the dominant color of the video.

I can understand extracting a dominant color from images, but doing so for videos seems unnecessary and unwanted. Moreover, this behavior is not clearly documented, making it difficult to identify the cause of the issue.

I would appreciate it if you could improve this.
The best solution, in my opinion, would be for the plugin to ignore video files entirely.
If that is not feasible, please consider adding an option to disable this feature in the settings.

Thank you for your consideration.
