DCTFilter a Winner?
Hi kwag and all others...
Have you already tried DCTFilter with the current optimal script? Filesize dropped for me by 0.5 MB on a Full Sampler 8O :!: :!: I looked at different frames of both scripts, and there's no detail loss. The thing that I noticed was that with DCTFilter the backgrounds got slightly darker. Well I used this line at the very end of the script: DctFilter(1,1,1,1,1,.5,.5,0) Try it out for yourself please... :D |
Jell please,
more details! where you use DCTFilter in the script? begining,middle or end? is built in avisynth252 ? thanks in advance! :) |
Use it at the VERY end of the script. It's not built-in, you can download it where you can download all the filters 8) :wink:

thanks Jell,
i'm trying it now. :wink: |
hey Jell,
i got 1 more point in CQ prediction. :wink: i don't compare the image quality, i'm trying to find high CQs values. :!: |

I cannot see that it does any big harm to the image quality, so if someone can confirm this I'm gonna PM kwag about it! :wink: |
@ Jellygoose..
I'll give it a try. I"m hvaing issues, but I remember a piece of source that I can try it out on, and let you know.. before my Dial-up runs out.. I'm cutting it close the the 10th hour hehe.. I'm rushing.. I'm assumging that by "end of script" you mean after the function FMIN() ??? I'll try both in any case. -vhelp |
No, don't put it after the functions. Put it right after the second Limiter() line, that where it belongs! :wink:
I don't know if it matters though to put it after the functions. Just trying to sound wise 8) |
@ Jellygoose..
Ok, thanks.. will do. -vhelp |
@ Jelly..
Sorry for the delay.. I had issues. I realize this is a small sample test, but I'm cutting it close to my dissconnet - sorry. -vhelp In short.. here goes what I have w/ latest script. * 20 sec clip - 1,490kb - w/out ## DctFilter(1,1,1,1,1,.5,.5,0) * 20 sec clip - 1,499kb - with DctFilter(1,1,1,1,1,.5,.5,0) EDIT: 9k loss, based on script below, and using DctFilter(1,1,1,1,1,.5,.5,0) filter at bottom: ------------------------------------------------------------ Code:

@ Jellygoose..
Sorry, but the above is what I concluded from the 20 second clip. I ment to say it grow 9k larger when using the filter :( The movie was "Dogma" - the train ride.. where they are tasking at the table.. an 1 Hour and 5 Min into the movie. -vhelp |

By modifying the 6the parameter, you enter in "frequencies" that the human eye can see. If you use "ffdshow" as filter for viewing you video, I suggest you to test your values with it : it has a "on the fly" DCT filter (just see in the option of ffdshow) :you can set the values you want and see directly on the video if you can notice a difference or not. For my part I'm stick to "DCTFilter(1,1,1,1,1,1,0.5,0). |
