As you all may have known; The commercials on the Videomercials has been recorded during the time VCRs was available in the late 1970s, and has been established ever since.
What you should know is that everyone's TV Picture Adjuster is set differently. For example, an old recording from 25-years ago that had a TV picture setting from a "different" TV Set is not going to automatically adjust itself to how your current TV picture settings are.
This is why some footage on Unofficial Releases that you may have purchased or traded for, may not look so good on your TV set. If you would adjust the "Soft/Sharp" picture tune (or on some TV Sets it might be called the "Picture/Detail" tuner), you will see how much improvement the quality will be on the footages.
You can also adjust the Color, Brightness, and Contrast for better picture quality.
Because the quality of the commercials at the time I've compiled them will look good on my television set, but when you receive the VHS or DVD it may not look as good because your TV settings and "TV Set" is from a different brand or model, and all you need to do is adjust the picture on your TV.
