I’ve made several attempts to extract a selected scene from the 4K… video files—namely using Windows’ Media Player ‘Trim’ feature to trim any given downloaded file (which gave me a message saying that I do not have ‘permission’ to do that), simply copying the file (on Media Player’s prompt suggestion before retrying Trim), and (finally before giving up on the idea) importing the file into Fimora9 (in the hope of selecting the scene in there), which resulted in an ‘unsupported file’ message. So, I’m more or less beat, I guess.
I assume from all this that the files are ‘locked’ in some way. Can anyone confirm this? It would help just to know if I’m wasting time trying to do something that’s technically impossible (at least for someone like me with merely average computer skills).
