First, you should check the file integrity because since your videos were recorded on an iPhone and uploaded to the NAS, there might be an issue with how they were transferred or encoded. Try playing the files directly from the NAS on your PC or another media player to ensure they are not corrupted. If they don't play, there might have been an issue during the upload or encoding process. You can also check out more ways to fix partially downloaded files https://www.linkedin.com/pulse/play-part...gasm-wln1e. Additionally, since you're using an older OptiPlex with relatively limited hardware, Jellyfin might be trying to transcode the files in real-time, which can fail if the hardware is insufficient. In the Jellyfin settings, make sure that transcoding is configured correctly, or try disabling it to see if direct play works. Another possibility is that the MP4 files are encoded in a way that Jellyfin doesn't fully support, so you could use a tool like HandBrake or FFmpeg to re-encode the files into a more compatible format
