Remove 3 seconds from end of video file

Is there a way to remove the last 3 seconds from the end of multiple video files without re encoding it all? Due to using a converter before, it added a water mark at the end of the file and if I remove 3 seconds off the end it is gone. so is there a way to do it without re encoding multiple files? Thanks

You could use Boilsoft Video Splitter for that.

Had to install K lite codec pack but works exactly as you said thank you. Saved me months of re encoding
