It is possible, but no-one on this forum can actually, or yes. But the thing is that you need major programs and players. To turn a vid a vid into hd you need to remaster it (I donīt know if thats the way to spell), and thatīs not easy. Old movies are remastered, that means they have to do start a new mastering process, and the product of that is a video or audio with less defects. Thats a way for old videos, but there are other ways that I dont know, but what I do know is that is not easy and it needs an audio or video engineer.
