Increasing compression through preprocessing
I've been playing with various smoothing filters and have come up with a nice combination for adding some serious numbers to the CQ level of a given movie.
Of all the combinations I've tried so far, what gives me the best compression increase is: Code:
FaeryDust() The script's output is quite smooth when viewed from WMP, and likely wouldn't be suitable for MPEG-4 encoding (or even high-bitrate MPEG-1), but for low-bitrate MPEG-1 it seems that the encoding process masks the lack of details fairly effectively. If you find this too much smoothing, try preset="movieHQ" for Convolution3D instead. These two filters are very slow, though :?. Anyway, that's what I've been playing with this evening. Make sure you get v4 of Dust since it fixes one of the bugs I mentioned earlier... Test and post :). |
Forgot to mention, I also used
Code:
Tweak(cont=0.8, sat=0.8) Oh, and I also put a Code:
Letterbox(8, 8) |
Hehe, this just never ends :mrgreen:
I can see it clearly in the (not too distant) future: The KVCD 300 minute (U)ltraLBR :mrgreen: :mnkypile: -kwag |

Maxed out at CQ 100 -- about 300kB below target size. I'm now going to watch the sample on the TV... Back in a bit ;).

Looks very nice -- perhaps a little softer than usual, but not a lot. I'm thinking of trying the DVD trick (i.e. heavy smoothing followed by an edge-enhancement) next... Of course the real test is an HDTV. Want a sample? :D |

Edit: Here it is, 6.5mB. |

I did use preset="movieHQ" on "Count of Monte Cristo" movie which is very dark with smoke or dust ( haven't seen the movie yet, just the sample 8) ) -kwag |

Check the file name :wink:

There should be a "Hall of fame" sample gallery, because that definitively looks like a DVD :mrgreen:
I'm going to re-encode "Count of Monte Cristo" again, which I had done at 352x480. I think that it can go on 528x480 with these filters :mrgreen: Just AMAZING :D -kwag |
What was your .avs script for that SansGrip :?:

Ok, so I lied. Here's the same 30 seconds from the one-disc version (112kbps audio). It's nowhere near as good as the two-disc (particularly anything very saturated in colour) but it's a heck of a lot better than without the extra compression from the preprocessing.
It's starting to look like I might get it on one disc at 528x480 after all :). |
There's no Blockbuster or Fluxsmoot there right :?:
