Not a lot. It might be possible to tweak the matrix, but the compression has to come from somewhere...

I was just testing denoisers :). I've since stopped using that one because it seems to produce visible chroma ghosting.

It might be the result of the borders not being a multiple of 16. If they aren't they'll occur in the middle of a macroblock, and artifacts will appear.

I read somewhere once (maybe Doom9) that "highest quality" actually "finds" motion that isn't there. Hence more motion vectors, hence a larger file size.

I'd still like to know what algorithm it's...

Smoothing would help reduce artifacts from the original, while adding noise would help hide the DCT blocks. It really depends on the source, and there's no correct general answer. There's only...

I don't see why not, as long as the material is telecined. You wouldn't want to use it on real 29.97fps interlaced material :).

595,860 * 0.97 = 577,984.2 which is even closer ;). It's a little below the final size, but a megabyte either way is well within reason -- even if it won't quite fit, a small overburn is usually not...

Force FILM mode is great if the movie is 100% telecined, but I often find some interlaced material creeps in there too (especially during special effects or when there are captions on the screen)....

I think you'll find that the audio sounds just fine at 112kbps if you resample to 44.1khz (there are noticible artifacts at that bitrate if you leave it at 48khz). That gives you a bit more room for...

Re: Prediction out by miles

Signs will be done in 5 hours, so I'll have a better idea then.

By the way, get this: with Signs I was able to use a CQ of 73 at 528x480 as opposed to Death To Smoochy's CQ of 62 at 352x480. This...

I'd be sorry to reintroduce that, because it's really just a hack. I'd like to know why we didn't need it with the previous settings but seem to need it now...

I'm not sure, but I notice that a lot of very dark movies are hard to compress (e.g. Panic Room, Resident Evil).

That's what I found with Death To Smoochy -- even at 352x480 it's not ideal quality. Strange, really, considering it's less than 2 hours long :?.

Re: Prediction out by miles

It looks pretty good -- this is a hard movie to compress, lots of bright colours etc. and a 16:9 ratio.



Yep, 6.3% or thereabouts. Too much. I think I'll reencode at 689 / 648 * 58.5 = 62.2 and...
