Thank you, that is the ideal solution I appreciate very much I’m afraid I cannot create my own player or format with my limited knowledge I’m kind of searching a kind of player + a small hack to achieve such goal

the purpose of the partially locked portion is To share with others selectively and To let everyone to quickly preview the contents The reason I mentioned the cloud is not necessarily get the support of the cloud system, I store the files on the cloud. so ideally viewer runs the file on his/her computer via link with a video player to be able to see the preview whereas another person viewing the same file in full via some sort of password, I don’t care if a decrypted file is kept in the authorized guest computer or deleted

dilemma is to create only 1 video file -stored at hard disk or cloud) can be normally viewed partially as well as in full only with a password etc

Thank you for your pointers; I appreciate them very much.

I’d like to have the option for video files , partially locked at the same time able to be viewable whether is stored at hard disk/PC or cloud), if I could (for security & privacy reasons)

I’m happy that I have started the discussion on the subject to generate some good brainstorming, which may lead to a quick hack that I can implement myself, rather than opting for expensive solutions, if any

I was thinking having the same 1 file can only play the first 15 min through a usual player as well as playable in full with another configured way

Thank you again.

I’m afraid I have no knowledge of Python or any scripting languages.

I hope this is just a beginner’s brainstorming session, and that someone can guide me as if I were five years old.

low security is ok, how can I go about it? any software or anything else I need to know

I’d like to do the following: for the first 15 minutes, I want to play the video normally and then either not show the rest or display a frozen image instead.

I occasionally encounter corrupted videos that only show certain parts and not the entire content.

I was wondering if I could replicate such a situation based on my selection. However, I would also like the option to view the entire video normally if I choose to do so through an alternative method
