I have recently started using Sony Vegas 8 but i have a strange problem when it comes to doing any video effects.
If i add color correction for example it works but not on the entire preview/render of the actual video, i get this little block of old colour on the movie.
I noticed that if i click drag my mouse on the preview i can move this around ie change location and side but not totaly remove it.
Anyone know how to get around this?
Thanks in advance,
