TV Frame/Overlay for 4:3 videos

In the retro emulation world, I came across a lot of new features for retro games in the last two years, and I’m using Kodi full time now to watch my offline collection.

In Retroarch, a multi purpose app for emulation and media, we have, for some time now amazing shaders and overlays we can use for basically any emulator, for effects, retro tvs, handheld frames and so on, so I thought when I’m watching 4:3 videos in Kodi, “I wonder if I could do the same, having a TV frame there, a CRT TV to fill the black bars while feeling nostalgic with it?”.

Here are some examples:

If it’s already available, how can I add it to kodi?

Thanks!
