Assassinator Wrote: [ -> ]I'm going to start watching Clannad sometime... after I get the BDrips from Thora (fuck Coalgirls, anyone who knows anything about encoding knows crf13 is dumb for HD material). Mainly because the TV airing's quality is quite horrible if I remember correctly, Mentar bitching about rainbowed dotcrawl or whatnot.
VS Thora's 20Mbps x264 encode (+ settings blanked out)?
If Thora is 20MB/s, Coalgirls is 50MB/s. (And Thora isn't 20MB/s... at least not in this case).
And I never said Thora isn't overkill, just Coalgirls is even more so. (Actually, Coalgirls is weird, their encodes vary a lot...)
Blanking out settings is dumb. Real encoders compile their own x264 edited to not include the SEI at all. Thora's settings weren't anything great anyway, at least from what I remember. Though they could have improved... (heh, I don't remember my own settings to be great back then either).

Seem they're both large.

From the above, it looks like Thora is going _less_ than crf14, as file size is bigger, plus they're using lossy audio track (speaking of which, I wonder what the source is, if it's AC3, then CG did something stupid, whereas, if it's PCM, then Thora is being whacky). Of course, that assumes that they start with the same source (most likely) and no additional filtering was done. From screenshots, they look very similar IMO.
Honestly, I'd have to choose CG out of the two.

Deleting the SEI is hell easy anyway (easier than blanking it out actually). Admittedly, I had to look at x264's code to figure out how.
