Hiding the length of content

[podonnell 50]

Hi,

Is there any way to 'hide' the length of content? I have some eSports games that I am adding to my library that I wish to not be able to see the end timing of. Would the length be pulled from the actual video codec information, or is there any possible way to edit metadata or .nfo files to make a video appear longer than it is?

Curious if there is any way for something like this.

Thanks.
