How do I remove the censored (blur) from a video? Please suggest for tips and tricks, how to remove the blurred part to original state of video.
Hovsep and Jan already touched on the subject, but just to explain a little more. Information cannot be recreated from nothing. If you have a blurry picture, it mayt be "sharpened", but that only increases the contrast in particular areas to give the impression of sharpness. It does not recreate the detail. Motion blur can sometimes be removed by clever algorithms which use the information from adjacent frames to "reassemble" sharp objects, but as the video in question has been blurred intentionally, all the frames have the same objects blurred, so there's not information that can be used to sharpen the object.
As Hovsep said, the blur is applied to the pixel within each frame. It's not some overlay or layer one can simply remove.
In general blur is countered by applying sharpness to the image or frame, sometimes even overlaying the blurred one with multiple sharpened image using a certain blend effect.
However, given the nature of censor blur I doubt one would get any reasonable results. It is intended to hide something and therefor usually doesn't provide enough details to restore it to it's original state.
i think you can't remove the blur because it is attached to each frame embedded into the picture
