:) i think that i found why we have differents opinions about STM.. as posted, you(Kane) "let ToK do the prediction with both scripts". you got differents CQ,right? than one of your tests got more CQ and show better quality. i do my tests and samples using diferents scripts and a little chapter(but complete chapter) with more or less 5 minutes. with and without STM filters in this case, but with the same CQ :!: (65 with each script) and adjusting the "spacing free" and "max file size" to 25 or 30mb :!: then i see better result using STM filter comparing the images!!! just a little,but better? make sense? :wink: |

yes, i got two different cq values, the scripts with STM have a cq, thatīs about 2-5 highter than the cq without STM, but the video quality with the higher cq is worse, than the one with lower cq. |
ok Kane.
:wink: but why we see differents qualitys? maybe the sources. :? mine is from dvd,and your? :?: |

dvd, too i will give kwagīs STM settings a try after weekend, if quality remains the same and the filesize decreases: OK, i will use it otherwise, i wonīt use it anymore. my script gives a perfectly sharp video, i can put on 1cd-r. thatīs all i want :wink: |
Spatial filters, Soften Filters, Shapen Filters its just a way to get around ugly video and get better image, But i wich they make a filter to get just Compression and nothing alse. Cause the thuth is the higher the CQ the less noise you get piriod and you only have 800MB to play with. filters like STM do give compression but at the expence of detail, so i just try to use the least amount of filter possible and try different settings and thats just my 2cnts and that.

but what is better without filters? (the least amount of filter possible) 352 x 240 with more CQ or high x high with less CQ? :? but :lol: i'm turning it all more confused! :lol: |

Thanks! :wink: |
I'm using STM filter with different sourses and as I see it it's very helpful with noisy or low quality sources . If u are working with clean DVD source It can be dropped off , else u need more compression .
STM ( for me ) makes very significant job with low quality sources . With KWAG's optimal script (before last update) I've managed to get so clean picture that my friend couldn't beleave to me when I showed to him source and resulted mpg . He thought that source was an encoded movie . To use or not to use (STM) It's up to u So do as u like :wink: :wink: :wink: bman |
I finally got around to watching a few Kwag-Optimal vs. Girv-MSoften xvid re-encodes on a TV (standard 28" widescreen).
Overall both scripts gave good quality results. With high quality sources I think Kwag's script perhaps had a slight edge, but with lower quality sources with visible flickering DCT blocks I think MSoften really helps. They seem about even on compression as well. Which is nice. Problems? MSoften (mostly) stops the blocks flickering but flat coloured backgrounds can end up looking somewhat blocky with no smooth colour graduation - like you'd converted it to 16 colours and back again (whats the name for that effect?) Is that better or worse than a randomly flickering background? Dunno. There are also blurring artefacts sometimes, mostly vertical edges being shifted sideways in parts (vertical lines becoming slightly wavy). But these are very short lived (<5 frames) and I only really notice them when stepping through the video frame by frame. To Do ? I think some sort of spatial soften / blur is required after MSoften to help with the blocky backgrounds; I'm looking at various filters but havent found a satisfactory one yet. You might like to try FluxSmooth, STMedianFilter or SmartSmootherYuv. Anyone know of a filter that can detect and blur horizontal and vertical edges over a wide area? Maybe I should stop encoding video and go and write one (I just know I'm going to be sorry I said that :) So to finally spend my 0.02c: DVD & HQ divx/xvid: Kwag's Other xvid/divx: Blockbuster & MSoften All totally 100% IMHO and YMMV of course :) Comments and improvements welcome! |
@ girv !
Hi !!! I have to agree with u but have some quastions : ===== So to finally spend my 0.02c: DVD & HQ divx/xvid: Kwag's Other xvid/divx: Blockbuster & MSoften ===== When U Say " xvid/divx: Blockbuster & MSoften " what params u suggest for both of them . Have u any favorite ones ??? bman |

That's interesting ! 8O 8O 8O
U are resizing , adding borders and right after all this u set all other filters ? Thats interesting cos I've got better results with all filters before resizing . It takes more time ( bigger frame to work up ) but resulted quality just worth it . I didn't try this way :!: :?: ( Stupid of me :oops: :oops: :? ) More to try :lol: 8) bman |

Note that I'm adding borders then removing them again with Crop. This is because the MSoften filter doesnt process the top and bottom of the frame so I add borders to give it "room to work" at the edges. |
@ girv
I'm using KWAG's optimal script with some small changes on prams of filters . bman |
