user29962: Is there any existing container (video format) in which the metadata is immutable?
I am new to this topic and my use case is that once a video is recorded, I want to preserve the metadata (for ex location, time, some caption used while sharing it, etc) in such a way that no one can alter this information, or worst case, only the original creator can do so.

user18155: Containers don't support encryption of metadata, and without encryption everyone may change what he wants (even damaging by his action the whole multimedia file).
There is a possibility to make a checksum of your file (as SHA-256), but it will not protect to change it, it only helps detect if the file is in its original state (not changed).
