There will always be some degrading or even a change to the picture quality if you re-encode to a non-lossy codec (which h.264 and h.265 both are, just like mpeg-2 is). Also, ya know, the lossless mode will yield huge files. Of course, you will lose quality going between lossy formats, but if x265 is 3x smaller than x264, my gut says to go with at least 3x the original bitrate. Yeah, aim higher to be safe (r). This is one of those "just hold your nose and test it" situations. Q6ZQ.
