touching up blu rays, simple filter combo?

[number82]

hey guys im sort of new to the whole using avisynth to convert movies and what not and ive been playing around with filters etc etc with some of the blu rays ive ripped to my computer (from discs the i have purchased legally).

anyways the type of rip im looking for is just basically a degrained, "clear" rip. and ive found out so far that i need to use a degrainer, obviously, and to obtain this clearer footage that im talking about apparently i need to use a sharpener filter. am i on the right track? its sort of hard to explain but basically im trying to make the footage like, more in focus than the original? clearer and no grain, basically just enhance the original. im really interested in this kinda stuff and ive got a decent computer for all the processing which is also helpful which is why i want to learn more about this stuff

problem is im not sure if my method/filters are correct. atm im using megui with the x264 codec on constant quality of about 20-22 and not touching anything else. and my avisynth filter ive been using asharp and playing around with values. things look.. different, like its sharper n stuff but i dont think my degrainer is working properly.

is there some kinda of basic combo of filters, or something you do in the other settings of megui that would give me a pretty clear result? or does it depend on all sorts of things im not even considering or am i not on the right track at all? any feedback, criticism would be appreciated thanks.

No, because every source is different. Some might need stronger settings or filters, some might need weaker, some might need combinations of things. There is often more than one way to achieve similar results

Furthermore, a lot of it is subjective and there is no "correct" or "incorrect" . Many people prefer grain - it's supposed to be there and often it's put there intentionally by the studios and director. Excessive degraining can lead to problems when you encode like gradient banding , oversharpening can lead to halos.

If you're looking for specific suggestions, then post a sample, and be specific about how you want it to look

well if thats the case then does that mean like every movie you want to back up is going to take hours of trial and error with different filters and then another 2 or 3 hours to convert the whole thing provided nothing goes wrong? sounds pretty impractical..? :confused:

Experience helps, but you can start by learning how to use basic avisynth scripts and pushing f5 to preview in avspmod. You can easily compare script versions in different tabs. You can preview before you spend/waste hours encoding.

The preview is what you would ideally get if you encoded lossless, but there will be some degradation when once it has been encoded

WHOA this preview program is excellent! it helps with filters too cause it like, tries to guess what youre typing in the box and tells you how its meant to look and all that stuff when youre writing it. thanks heaps for that! if you dont mind me asking now, is megui a good program to use for the encoding bit? it has a lot of options in the codec part of it and dunno if im just meant to leave all the options alone or what. or should i ask that kinda stuff in another section of the forum? still sorta avisynth related i guess. oh and are their any other avisynth programs i should be using such as the avspmod one? thanks

It's more a GUI related question, and might be better if you had asked in that section...

But anyways I think it's a good place to start. If you leave the advanced options uncheckmarked you can stick with the simple presets, yet if you feel like tweaking , checkmarking that box will expose many of the options in a GUI format.

Start with the presets and tunings of x264 , or the megui profiles, then you can start learning about what the settings do. You can read a brief description here

As for avisynth tools, I think AvspMod is really the only one you need. Sometimes you need to preview a script to see how it looks in motion (ie. play it), and you can do that in something like MPC. But some filters or combinations are very slow to process, and you might not get realtime playback
