Auto-adjust exposure filter?

I have a video where basically all frames have different exposures, due to the lightning in the room. Is there a filter that can auto-adjust exposure/brightness for me? Or do I have to do it frame by frame?

I would say a combination of filters such as white balance, brightness, contrast, etc. might help a little. But this is something that affects the whole clip, and applying it over a whole piece might not help balance it out too much. Ideally you could try splitting up certain groups of clips that have a similar balance together and manipulating the filters on those to create something more harmonious, but a lot of it is open to interpretation. Sorry for a delayed response, I hope you have found something that works or maybe this will help.
