so lets say theres an object that i want to hide, so i take a piece of the background as a layer and put that over the object to hide it
after doing this, it usually doesnt look perfect and u can see that the video has been tampered with in that location....what are some of the standard ways/effect controls to quickly blend that fake background uve made with the real background
you probably mean color matching. It requires applying to the forground element contrast and color adjustments as well as blur an grain if needed so it will match the background. There are different techniques to color match a Forground element with the background. I would recommend studying about it and find what technique you feel comfortable with.
alright, im not trying to get it perfect or anything...just something half realistic
so between those things and feathering i think it should be fine?
