Hi. I was looking for encoding software that supported video filters and just happened to run across MeGUI. I know very little about AviSynth scripts but I'm learning. I found several tutorials and guides on writing scripts. Getting to the point. This pic below was taken from an encoded Dragon Ball GT episode with the following specs:
20 min. 44 sec.
MPEG-4 AVC Video
3 Audio Streams (AAC, 2 CH, 48 KHz)
640x480, 23.976 fps
File Size....... 96.4 MB
Basically.. I want to encode like this guy lol. I used to encode anime a while back using Handbrake. Handbrake simply cannot touch this level of quality (with such a small file size) and it does not support real video filters. I have no idea who did this nor what program they used but I am certain MeGUI can pull it off as well. What settings and filters do I need to use to achieve this level of quality for a 22-24 minute video? The file size can be anywhere from 90-200 MB. Or at the very least, tell me what kind of filter(s) makes your video look like this...

You have to use specific filters and tweak the filters and encoding settings. You wouldn't be able to use exactly the same settings for every source. For example, some might need denoising than others, some may need more saturation etc...
Without a point of reference or where you are starting from , nobody can give you any specific help.
If you upload a video sample of the source, people can give you more specific suggestions -
Got ya. I think I'm beginning to get the hang of this. Can you point me to a list of Avisynth video filters? Such as sharpen, smooth, etc.
-
there isn't a good all-inclusive list, they are spread all over the place and constantly being developed;
here are a few to get you started
http://avisynth.org/warpenterprises/
http://avisynth.org/mediawiki/Internal_filters
http://avisynth.org/mediawiki/External_filters
http://www.aquilinestudios.org/avsfilters/
a good place to check for more advanced filtering and expert feedback is doom9 forums -
Hmm... Does anybody know where I can find LimitedSharpenfaster?
-
whenever you're looking for specific filters, search google for "<filtername> avisynth mediawiki" or "<filtername> doom9"
http://avisynth.org/mediawiki/LimitedSharpen
Most people use LSFMod these days, it has been modified slightly and more tweakable
http://avisynth.org/mediawiki/LSFmod -
Thx for the info!
-
Ok. Last question, is it possible to specify a file size with Avisynth? Thanks for all your replies.
-
nope, that's the job of the encoderOriginally Posted by Nagashi
filesize = bitrate x running time
Using denoisers and degrainers through avisynth will help compressibility. Noise & grain "eat" up bitrate and are very costly to encode. Ideally you want to target noise reduction, aiming to keep as much detail, but reducing the noise instead of making it a blurry mess -
I know I said I wasn't going to ask any more questions but I need to know, in your opinion, what's a good denoiser, degrainer and video smoother? Please just name one of each. I found everything else I was looking for and these three things is all I need. There are so many plugins to go through and read up on.. Ugh... I think I need to lie down for a bit.
-
It depends on the type of noise, the type of grain. You have to customize the function and settings for best results, otherwise you erode too many details. For anime, it's usually more forgiving than live action - you can go overboard more
MCTemporalDenoise is one of the best generic filters , but there are many settings to play with. It's like a mega filter composed of a dozen sub filters
If you click on that last link, it provides before/after screenshots of some of the older filters (unfortunately hasn't been updated with newer filters)
If you want specific suggestions, post a sample of your source video and someone will provide suggestions -
Ok. Here's a sample I've been experimenting with. It's the intro to DBZ Remastered in .vob format. But it is about 43 MB. I also noticed that MeGUI doesn't encode each scene in order as it should. Some parts will play more than once in the encode... I sometimes have this problem while encoding VOBs. I stripped out the other angle but it didn't help. I guess it doesn't really matter because I'm just experimenting with it.

More questions for you guys. From what I've been reading, MDegrain and LSPMod are scripts. I'm still trying to wrap my head around this. Since they are scripts, am I only supposed to insert the text into this .avs file? I have all of the needed .dll files for both of them in my Avisynth plugins folder but I'm not sure if I'm supposed to use LoadPlugin for any or all of them.
The way this script is now, I really don't think MDegrain and LSPMod are even working lol. I saw no difference in the encode or encoding time when I added them both. I had the same issue with MCTemporalDenoise. It's just a script that requires a ton of plugins but how do I make it work? Also, is there a simpler / cleaner way to add scripts? Like for MCTemporalDenoise for example, can I simply place that .avs into Avisynth's plugin folder and then have the script I'm using load it somehow? @.@
Lastly, does Avisynth support video enhancement filters such as 2xSai, etc?
Here is the script I am currently using. Feel free to bash / criticize it in any manner.

You're right. What you are doing is just declaring the functions (making them available) - you still have to call them, using code like:Originally Posted by Nagashi
SMDegrain()
or
LimitedSharpenFaster()
If you rename the .avs to .avsi and place it in the plugin folder, Avisynth will load it automatically. You will still have to call the function as I said earlier.Also, is there a simpler / cleaner way to add scripts? Like for MCTemporalDenoise for example, can I simply place that .avs into Avisynth's plugin folder and then have the script I'm using load it somehow?
Similarly, dll's in the plugins folder are loaded automatically without the need for LoadPlugin(). -
Got ya. Thanks for the info!

most .dlls are autoloading if put into the avisynth\plugins directoryMore questions for you guys. From what I've been reading, MDegrain and LSPMod are scripts. I'm still trying to wrap my head around this. Since they are scripts,am I only supposed to insert the text into this .avs file? I have all of the needed .dll files for both of them in my Avisynth plugins folder but I'm not sure if I'm supposed to use LoadPlugin for any or all of them.
.avsi are autoloading scripts if put into the plugins directory
.avs are manually loaded - use Import("path\script.avs") . You can rename extension to .avsi to autoload
BUT - you still have to make the calls in the script with the proper settings. Just because you have an autoloading script or dll, doesn't mean it works until you call it in the script. To call it in the script, you have to use the name. If you specify no arguments, it will use default values.
e.g.
AVISource("video.avi")
LSFMod()
the more stuff you accumulate in the plugins directory over the years for autoloading, the more slow everything will be. For this reason many people choose to manually load stuff
Don't use directshowsource() for your source filter. It's not consistent or necessarily frame accurate. I highly recommend using DGIndex for MPEG2 (DVD) sources.
There are instructions included with every avisynth filter. Sometimes in an .html file, sometimes in a text file
This is a telecined source. In order to recover the progressive frames, you have to inverse telecine. You can use TIVTC in avisynth to do this.
https://www.videohelp.com/glossary?T#Telecine
https://www.videohelp.com/glossary?I#Inverse%20Telecine,%20IVTC
http://en.wikipedia.org/wiki/Telecine
This sample isn't very noisy compared to other anime, also it's the remastered version. The original had nasty field blends and was alot messier.
So an example script is below. This is just to get you started, you can add more filters or tweak it to your preferences. So I would index with DGIndex (make sure video=>field operation honor pulldown flags is set). You need TIVTC.dll in the plugins directory.
Beware of "filteritis" , the more filters and crazy scripts you use, the slower it will be, and more memory consumption. If you are using 2pass encoding with heavy filtering, it's usually wise to encode to a lossless intermediate first (e.g. huffyuv or lagarith), then use that intermediate to encode the 2pass (so you only have to undergo the filtering once instead of twice)Code:MPEG2Source("DBZ Remastered Intro VOB.d2v") TFM().TDecimate() MCTemporalDenoise(settings="high",strength=250,edgeclean=true) LanczosResize(624,352)
A good tool to use is avsp. You can compare different scripts in different tabs and switch back & forth to preview. It's a good way to learn the effects of the various filters. -

Yup. The .exe is about 2.98 MB.Did you do full install of avisynth?
Yar. Ver. 1.5.8.0.
Tried it with and without loadplugin. Same errors.otherwise you have to LoadPlugin("PATH\dgdecode.dll")
I get that error no matter what I do. It doesn't matter what's in the script. Now it's saying "Problem in Avisynth Script. Attempted to read or write to protected memory. This is often an indication that other memory is corrupt."Last edited by Nagashi; 21st Jun 2010 at 13:33.

I've never seen that error message before
maybe you have a bad memory stick?
try running memtest86+ or other memory integrity programs
Try rebooting
Did you create the script in notepad? Try copy & paste into notepad, save, then rename .txt extension to .avs
Also, be careful about adding that high of a saturation (i noticed you added tweak(sat=1.3) - it will override gradients and obscure lines. This source is already very saturated IMO. I added a screenshot in a zip file comparing to illustrate (comparing original script and if you added tweak(sat=1.3). - you can notice the shading is destroyed
I highly recommend you use avsp to monitor your previews and see what the script and filters are actually doing - this is how you learnLast edited by poisondeathray; 21st Jun 2010 at 13:44.

I can preview the video in MeGUI. I noticed the difference and thought it looked pretty good but I guess it has its' drawbacks. I'm going to try memtest86 and see if it helps any.

If you are getting errors from any script, it's probably something incompatible in your autoload plugins folder. Did this problem start around the time you added a bunch of new plugins?Originally Posted by Nagashi
Try emptying out the folder (apart from the standard DirectShowSource.dll) and copy them in one at a time until you find the culprit.
If you post a list of the folder contents here, perhaps we can identify something wrong.
BTW What OS are you running? -
This was before I started getting the error.Hold on, how can you preview it in megui if you get that error message?
Yep. I found the culprit.... It was FFT3Dfilter. Dunno why. I replaced it with another version and that fixed everything.Try emptying out the folder (apart from the standard DirectShowSource.dll) and copy them in one at a time until you find the culprit.
Question: Is it possible to encode parts of a video file? And can I select which parts by using a time code? -
Yes, you can add Trim() to the end of the script . It works by frame numberQuestion: Is it possible to encode parts of a video file? And can I select which parts by using a time code?
Trim(1000,2000) would encode frames 1000-2000 -
Fantastic! Thanks!

Arg... Ok. I am trying to get Avisynth to load a mkv video and mp3 audio file, but it refuses to load the mp3 audio file. I have tried nicaudio.dll and mpasource.dll w/ no luck.
Here's what it's looking like so far:
Video=DirectShowSource("C:\Users\Nagashi\Desktop\Project X\DVD Author Lab\no audio.mkv")
Audio=NicMPASource("C:\Users\Nagashi\Desktop\Project X\DVD Author Lab\01.mp3")
AudioDub(Video,Audio) -
other source filters you could try for audio (you need the plugins for the first 2, they are not internal avisynth source filters)
FFAudioSource() - from FFMpegSource2 project
BassAudioSource()
DirectShowSource()
DirectShowSource() is not recommended, and used only as the last resort, especially if you are doing temporal filtering in the video (it's not frame accurate). For the video, I wouldn't use it either, I would use FFVideoSource() which indexes your file, and is frame accurate
eg.
vid=FFVideoSource("no audio.mkv")
aud=FFAudioSource("01.mp3")
AudioDub(vid,aud) -
Thank you very much. Your limitless well of knowledge never ceases to amaze me.
-
As well as poisondeathray's suggestions, you could try a more recent version of nicaudio, where the function is called NicMPG123Source.Originally Posted by Nagashi
