Need AVISynth Filters and Recommendations

[jowel13]

Hello,

I have these following lines in my avi.avs file to be encoded in CCE....

DirectShowSource("D:WonderYears.avi")
BicubicResize(352,480,0.0,0.6)
ConvertToYUY2()
ResampleAudio(48000)

I am encoding my whole Wonder Years Set that I recorded from TV to DVD. What are some filters and other recommendations that I can use to clean up the video? The video isn't all that bad, but I would like it as much as possible exactly like the original. Also, what are some settings in CCE that I can use to clean up the video, and reduce the blockiness? (Image Quality Priority, and Anti Noise Filter, etc.?)

Thanks!

Not sure what others are using for this but I stumbled around for a few weeks before I found this...

LegalClip()
SpaceDust()
sharpen(1.0)
mergechroma(blur(1.58 ))
mergeluma(blur(1.0))
Convolution3D(preset="movieLQ")
LegalClip()

This came from Kwag's script over at kvcd.net. He states:
This will over enhance details, and also artifacts. Now we apply the merge functions, also with max values, which will then soften the image. Still, the final mpeg will be sharper than with the old script, but the thing is that there are hardly any visible artifacts left compared to a script with smoothers.

I added Convolution3D (proabable overkill).. but it worked very well for high action footage captures from Children of Dune...

Thanks for the reply.

Also an addition to my first couple of questions, may I ask how people trim their videos to cut out commercials in their .AVI files?

Where do you guys get those exact numbers from?

It seems really complicated and time consuming to get the exact numbers for the begining and the end of each commercial.

Gratias!

I usually do my editing outside of my encoding process, but I believe avisynth has the capability of doing so....

Take a look http://www.avisynth.org/index.php?page=Trim

Also, I believe you can get the frame numbers you are after by using VirtualDub. I haven't tried this method, so I can't offer anything more than theory.

I believe in the script you would put your clip commands prior to any filtering you would do... Also Avisynth apparently has the ability to also clip the audio as well, so you get audio/video in sync...

Goodluck!

p.s. if I get time to mess with this in the future, I'll give it a try!

To get rid of commercials with avisynth do this

Open file in vdub at the bottom it states the frames write down the starting frame scoll along until you get to the next end bit and write that down

So it looks like this

AviSource(Blah Blah)
Filters and what not
Clip1=Trim(700,14000) retains the frames between
Clip2=Trim(18329,22533)retains the frames
Clip(Clip1+Clip2)
resize blah blah

If you go over to the edit in the how to and look in the how to edit with avisynth there are plenty of sample scripts and how to's

I tend to use an anti noise and my favourite the unsharp mask....it sharpens and smooths like a legend depending on my source I cap from cable so my source is pretty much free from static noise so I use the levels to adjust my colour and unsharp mask to fix the vid just that little bit more...have had amazing results .....but it depends on the source and even how you captured it ie with antenna or cable video etc

I didn't see a deintenterlacer in there, which might be an option.
Dust is a popular denoiser over at doom9 right now. I like it. It does spacial and temporal smoothing and is really easy to use.

Since it's been brought up, can you use VDub to frameserve the edited show into Avisynth, and then frameserve to whatever? And save the writing down of which frames to cut?

"Since it's been brought up, can you use VDub to frameserve the edited show into Avisynth, and then frameserve to whatever? And save the writing down of which frames to cut?"

Well I don't think vdub can do what your explaining ...unless I am missunderstanding..

You cannot retain mulitple segements in vdub I think..gogin thru and selecting the frames isn't that time consuming and the benefit is (especially with avisynth) that you can preview your script in vdub

This is the process I use

Go through the original avi and jot down the frames.

Then write up my script

once I have my script exactly how I want it with no more changes to be done I open it in vdub and extract the audio.

I encode the film with CCE 2.5 and do the audio with Tmpgenc then multiplex the video and audio streams in tmpgenc. I have never had and bad results doing this, always in sync and beautiful pictures (I encode to CVD until I get a dvd burner)

The other day they broadcast Ben Hur it was a 30 gig file on my hd
I had to split it into 30 different part to get out the commercials and apply delogo (for the network logo kept popping up) I it turneed out beautifully

[trillium]

thefox, THANKS! Forgot about delogo (haven't used it yet but I will probably end up doing so...) is there an avisynth release or are you loading it through vdub and doing it that way?

I use a similar process to the one above..
Frameserving an edited avi (which I edit before hand and save out as an avi), with avisynth to TMPGEnc, encoding to mpeg2 format. Audio was saved from editing program as 48 kHz wav, in which I encode to .ac3 format in AC3Machine/Besweet.exe to 224kpbs.

Haven't had any sync issues as of yet
Though with avisynth's capability of editing avi/wav I may change it a bit if that works better then what I've been doing (one less step!)

thanks

I use the same basic process as Trillium, but just wondering aloud here...

Use vdub to edit the commericals, but instead of saving a new AVI, start a frameserver -> avisynth -> tmpgEnc (or second location of vdub?)

Are all these filters implanted in AVISynth already? Or do I have to actually download all of those before, and install it in before I use them?

I can't wait to sharpen up my videos!!

Thanks!

LoadPlugin("C:\Program Files\AviSynth2\plugins\DustV5.dll")
LoadPlugin("C:\Program Files\AviSynth2\plugins\Convolution3D.dll")
LoadPlugin("C:\Program Files\AviSynth2\plugins\LegalClip.dll")

sharpen, mergechroma, and mergeluma are built into avisynth (I am using 2.08 for this).

Check here for what you need to download: http://www.avisynth.org/~warpenterprises/

fortension, when I used VDub to edit out commercials (this was animation granted), I came up with alot of audio sync issues. I haven't tried it yet but I think the idea of using clip may in fact be the way to go and just use vdub to get the frame info you need....

[fortension]

Hmm. I've never had vdub cause sync problems, after thousands of uses.

On topic, start with only one cleaner, like dust or convolution. There are several sharpening program types out there. I've taken to Xsharpen. Start basic, and then add the others in and see if it looks better. Novices have a tendency to overcook the video (I did too).

Thanks for all the replies.

The main filter that I am looking for and hopefully will find within the next couple of tests, are filters that reduce blockiness during fast motion scenes. In some scenes when Wayne Arnold fights Kevin Arnold all you can see are blocks surrounding Wayne's fists.

Hopefully I can smoothen those out with some filters.
