File name matching, not accurate, may return multiple ones for the user to choose from. After one user selects, the hash can be recorded, and hash matching is used to match other users
Video or audio feature matching can only match the features of the first few minutes, similar to listening to music and recognizing music, it can be regarded as an advanced hash matching
Most users are ordinary users who look for ready-made resources and do not know how to edit themselves, so the first two methods can handle most situations.
That’s pretty much what I said above I would like to add that the general method of Hash matching is to get the front, middle and last bytes of the file and take them out to calculate MD5
Most of them are file names. Different videos correspond to different subtitles. If you search online, you will see that almost every version of a movie will correspond to a subtitle. Basically, if the file name (resolution, production team, version) does not match, Nine times out of ten, the subtitles are misaligned
