Okay the 480p raw stream is encoded with the same settings minus the blu-ray compatibility option. It is more than 1gb smaller. I remember Chewtobacca saying how he thought the encode was quite big at nearly 4.5gb and now I guess we know why that was. It's now about 3.3gb and when I demux the stream it comes out at 24fps instead of 30fps.
I believe I also found the reason why some of the whites were getting clipped. Mysycamore commented on this. I'd have never noticed it otherwise. The 480p stream that I originally released was essentially the raw capture encoded to x264 but I did apply a levels tweak which I thought would not clip anything. However, coring was by default set to true which automatically clips stuff when you use it(I think). This time I have not adjusted anything whatsoever. It's just been IVTC'ed and a couple wonky frames have been fixed but other than that it's untouched. It looks a bit washed out because of this but is easily fixable with a few tweaks. I plan on releasing it completely untouched this time however.
I feel like such a noob sometimes lol.
