Wipe the EXIF data on the images when you make it public and nobody will be the wiser ;)

It’s not exactly watermarking; each encoder works in a different way and it’s readily possible to determine (for one versed in such matters) which encoder was used to generate a video by inspecting the structure of the raw (eg h264) bitstream. This might not work reliably enough for simpler codecs like JPEG but for something as complicated as modern video codec where there are a million ways to generate a compatible payload it is as unique as a fingerprint.
It’s fairly useless since raw footage isn’t typically distributed; it would be re-encoded first which would definitely destroy that watermark. So it would be a scandal that doesn’t necessarily accomplish much.
I’m not sure. Like how color printers write their serial numbers and date and whatnot on every page, these devices might be watermarking every video subtly, and we might not know it.
