You won't have that problem with Video Booster. This is a simple application that automatically improves the quality of your videos, especially in terms of sharpness and contrast.
Whether you're working with home videos or something you've downloaded from the Internet, it's possible that the video quality isn't that great. Now you can add it to this program and view an automatic preview of the improved version.
One downside is that the program may be too simplified; you can barely control the adjustments that it makes to your videos except to decide whether or not you want to improve the color palette as well. This lack of freedom may be frustrating for more advanced users.
But if you want to notably improve a video without needing to spend hours browsing through complex options for filters and codecs, this application will do the job nicely, and promises to leave you with a better video than the one you started with.
