Removing “fog or haze” caused by humidity from video
Hope someone can point me in the right direction. I was using a GoPro camera attached to the front of my Jeep hood. During our trip we did some water crossing and the heat of the radiator created the usual hot humidity cloud. After that, it seems that the case on the GoPro got humid and the video got a “fog or haze” like look. Check the snapshot here:
Is there a way to clear the image. I know it won’t look like it was supposed to, but at least make it watchable. It’s almost 2 hrs of video lost if I cannot fix it. If there is a plugin I can get for this let me know please.

You’re stuck. It’s so diffuse, with almost no detail or contrast at all, so there’s really nothing to try to coax out of the image.

There is nothing you can do in my opinion. But next time, try to monitor the camera while you’re shooting. Also understanding convection can be helpful. The lens surface needs to be warmer than the environment to keep the lens clear. Humidity is a bear though, and since you’re driving into it, and cooling the lens while you’re driving, it makes sense that the humidity is ravaging your lens. Consider a warm, clean glass in front of the lens somehow. In that kind of humidity I would really think that one through first. I know what it is like coming out of air conditioning with a camera and it fogging up for a long time after. Sometimes I will face the lens to the sun to warm it up quicker and get it hotter than the environment as fast as possible.

GoPro does make anti fog inserts. It may not help in extreme situations like yours.
If there is a next time, mount the camera in a different location.

I have a foggged GoPro video, or two, also–I’ve already bought GoPro fog inserts for the next time.
video 1: https://www.youtube.com/watch?v=VOgLQDwiDz4
video 2: https://www.youtube.com/watch?v=mpwjsSh-bkgThe images seem usable, but I can’t find a utility that will ‘defog’ the videos, yet.If it doesn’t exist, what settings do you suggest playing with, e.g. contrast, gamma, white balance, etc.
I am looking at software for editing videos, e.g. Corel Video Studio, Sony Movie Studio are two I have downloaded. Is there another package that you prefer in the sub $100 range that will best recover these videos? free?
