White Grainy Overlay On Video

[griffior]

Whenever I render a video, there's a white grainy overlay over the whole screen. It's only at the beginning, end, and when ever an overlay is removed or added onto the video.

 

Link for example of graininess at beginning:

 

Link for overlay example, skip to 16:28:

...never really seen that happen???

 

It is kind of like the result you see when you increase the Lightness and there is nothing there to increase

 

These were from some video shot in a cave:

 

50%

 

55%

 

60%

 

However, to just do a small portion of a clip takes a lot of deliberate effort

 

So is there a fix for this? Or am I going to have to move to a new editor of some kind?

 

Edit: Just started editing a new video. If you look closely, it looks like it squeezes the image in white it's bright then goes to normal.
