I did that but seems it is not working or probably i am doing something wrong. What i did-
I splited the segment(by pressing “S”)and then used effect (neat video) on that segment. Then joined the segments and after selecting whole footage i created new group by right click (and selecting “create new group). Finally rendered the whole footage.
neat video seems effective when i watch clip withing the vegas but noise remains as it is in the rendered new clip..
please correct me if i am wrong somewhere..
