I was reading a few tutorials on other sites recently about giving your own productions that 'movie look' and decided to try out some of the effects in Sony Vegas 9. I wasn't looking for a specific look but just to warm up some video I shot recently that had a noticeable blue or cold look about it. The one I tried was Color Corrector (Secondary) and just altered a few settings.
Preset: Studio RGB to Computer RGB to get rid of the inherint grey layer and make the blacks much stronger.
I set the Angle to 135.0 and the Magnitude to 0.272
Gamma was set to 0.948
Gain was set to 1.164
Offset was set to -12.0
Those setting may not work on your video but if you are looking for a starting point to give your clips a 'look' rather than just using the settings the camcorder chose, then try them out. All other settings were left as default.
