Changing Cover Art for Video file

I just got serviio. After indexing my media files, several home videos which were titled "18th Birthday" have inappropriate cover art.
How can I change the covert art for these video (MTS) files?

By default, Serviio is configured to collect metadata for your media from an online database. It does this by trying to match the file name with something that matches within the database. As you have discovered, when it doesn't find a match it can latch onto something completely inaccurate, and sometimes those have "less than desirable" images.

The easy solution is to put any personal media you have (that obviously won't have a matching name in the database) in a different folder that you link to Serviio separately. For example, let's say you have a separate hard drive for your media (for the sake of discussion, we'll call it your F: drive) and you have told Serviio to index all media on the F: drive. What you need to do is to create two separate folder on the F: drive, one for your commercial media (F:\media, ripped movies, recorded TV), and one for your personal media (F:\personal, video recorded by yourself or friends). In the Serviio console, you create two separate shared folders in your library and remove the one that is scanning the entire hard drive. On the folder location with your personal media, uncheck the box that says "Retrieve descriptive metadata". Serviio will not attempt to download any metadata for any files in that folder.

If you don't have a separate hard drive for your media, just make the same separate folder locations for your media and map them separately in the Serviio console as I mentioned above.

I have a bunch of test video clips that I had to do this with. Yes, I could absolutely get some very strange metadata information on many of those titles, so this was the simple way to eliminate the problem.
