Hi guys, sorry if this is in the wrong place, I thought I would get the best answer here.
Basically, I'm editing together a video of Ireland's Euro 2012 Qualification campaign, and I have my clips trimmed and put together, but when I try to add an effect (warm vignette to be specific) the clips become choppy, particularly when transitioning from one clip to another and the music skips a bit, as if my computer is struggling, although I don't think it is. Is there something I'm doing wrong? How can I add the vignette and keep the clips running smooth?
Any advice is greatly appreciated.
