Now, checking if each component is standard. Filenames often follow a structure: title.year.resolution.source.codec-releasegroup. "ATVP" isn't a standard abbreviation I'm familiar with. Possible possibilities: maybe a typo for "ATM" or another term, or perhaps it's specific to a particular source or group. Without more context, it's hard to say. However, the rest of the components are standard, so "ATVP" might be a mistake or a niche identifier.
