The Blue Aurora Borealis That Would Not Die

MessageAuthor

I'd like to correct what I posted for Chillout just a while back. I'd said his h264 clip encode had superior color saturation in YV12 adj mode compared to my xvid settings that outputted to YUY2. False. Opening and closing different versions of that clip in ffdshow induced the very opposite color space specs that I'd mentioned. Meaning: I could open Chillout's h264 file in YUY2 faded cyan mode while conversely opening my own in that deeper magenta YV12. This is absurd. How can the same file be opened in different colour spaces using the same codec simply by opening and closing the player successively. I've never seen anything like it. To qualify the problem, it seems to happen when I open multiple windows in zoomplayer, the first being YV12 the others YUY2. And as I still don't know the relevance of either space to the final result, it sometimes makes me want to chuck this video string theory business down the drain and long for my Kodachrome/Velvia days of not so long ago. Ok, I managed to translate one of Teeg's profiles (the 58% quality one), and the same size encode produced no improvement whatsoever over my standard area+smartdeinterlace+smartsmoothHQ settings at 2500kb/s. So much for that.

RE: The Blue Aurora Borealis That Would Not Die

HI there i think the reason your experiancing different colour spaces is that the hardware overlay which is normally yv12 normally can only be engaged once if you have a video open then that will be using the hardware overlay of your graphics card. I would also point out that the overlay can have settings that differ from your normall display settings that only affect video that is played back using the hardware overlay. Ok the settings i used avisynth plain mostly but i used toms motion compensated detinerlacing filter. apart from that i used bassically every bell and whistle mainconcepts v2 encoder had. I would however like to point out that i used x264 but it too had blocking issues on the sky also nero digital avc as well. I tried divx and xvid both had the same issues. I suspect that mainconcepts h.264 encoder is filtering the chromatic change out as this product and as this product was primiraly targeted for content creators with uncompressed or dv source.
