[QUOTE=ChristineBCW;2694115]Does anyone have any positive feedback about the process of “Converting Conversions”? That is, taking a file, converting it to one format, and then converting that conversion to another format?
Has anyone ever had a completely positive, 100% perfect experience with that?
I’ve always detected a lessening-of-quality…
Yes, I’ve done “conversions of conversions” that are really quite good. For example, taking an xvid avi copy of a dvd and converting that to H264. But it really helps to have excellent material to begin with. In this example, dvd-video as the starting point, the original video can be any level imaginable. I’ve seen commercially made dvd video that looked as bad as VHS. And I’ve seen some that can come close to rivaling an average commercially made blu ray.
My conversion went from a ~5gb dvd video, to 2.2gb xvid down to 1.2gb H264 and it is still quite good. Better to start with the dvd of course, or from a blu ray source, but using x264 in two passes or CQ of 18-20, you’ll be surprised at the quality that is possible. And H265/HEVC is promising even greater compression.
