Can Screenblast Correct Overexposure?

I have a clip that I wanted to use as part of a video. I captured it from the VHS tape and added it in. After rendering the MPEG and putting it on DVD, it looks really bleached out. It looked this way in the preview screen while working on it, but I thought that was just the fault of the preview. Any way to correct the overexposure?

OK, I found the instruction to correct the overexposure. Screenblast says to adjust the overexposure using the Brightness and Contrast Filter (slide the bar either way to over/under correct). This would be wonderful if I could only FIND the Brightness and Contrast Filter! Can anyone please help? Thanks in advance.

Gerry, it should be under the Video FX folder.

Thanks Ian, but it didn't work for me. Trouble was that only part of the picture was bleached out. Example: Water cascading down the mountain was so bleached-white that that it didn't even look like water, yet the people standing in the water looked fine. But thanks again for the info, I'm sure I'll use it some other time.

To see what I'm getting at, I rendered 20 seconds of the video. Have a look at it: http://www.mts.net/~gerrylea/Cruise_wmv.htm

The red arrow points to me. The title should be "Large tourist climbs Dunn's River Falls".

Now that you've seen it, any suggestions? (besides "lose weight")

I've seen your video clip. Unfortunately there isn't much you can do about footage like it, other than try to move your camcorder to eliminate the overly bright part of the scene. Here, you could have filmed the people so that as little as possible of the rushing water got into the scene, then filmed the water itself separately, with a neutral density filter and/or your exposure reduced. Then, in Screenblast you could place one scene right after the other on your timeline, with each properly exposed separately using the Brightness & Contrast filter.

I've had marginal success in these scenes using the Moderate Bounded Spotlight from the Light Rays video fx. I spotlight the dark section of the scene, which dims the brighter portions around it. Try playing around with that. It's not a great solution, but helps a little bit.

Where in *%#@! did that "iTunes" title to my message come from? Pardon me, I haven't a clue as to what I must have done!

Hi Klavisha,

I had a simliar problem, and found out that I'd let my browser save my forum login ID and password one time when I replied to a message. It wound up also saving whatever was in the subject line of the message that I was relpying to, and substituted that for any message that I wanted to reply to after that. Plus, it made additional, identical IDs for me -- generally a pain in the butt. Had to delete the others. Now, after I hit "Post Message" I say "NO!!!" when Password Manager asks I want to save the user login and password.

I'm using Mozilla 1.4 for unix, by the way. Haven't seen this problem with IE, which I use at home.

Hope you can fish enough out of this to solve your problem. It's pretty annoying.
