I'm using Vegas 7.0. I want to brighten my video clip. But no matter I use the brightness or colour curve to make it brighter, a vertical dark bar will appear on my clip. How can I eliminate the vertical bar?
Do you mean the screenshot in Video FX.? I tried but the vertical bar still in. Actually the vertical dark bar appears whatever video fx features is on the clip.
Perhaps you have the effects bypass enabled. There's a button just above the preview window that has a dark half, a light half, and a circle in the middle. With this button enabled part of the screen will show the effect applied and the other part will show the original video without the effect. Try clicking on this button to see if the problem goes away.
