AVISynth Wizards-Flickering Text

[Alwyn]

Hello all you AVISynth wizards. I have a slightly annoying issue with the credits on this video. Portions of the title text are flickering up and down. I haven't the foggiest idea about how to minimise this and would appreciate any help you can give me.

The MP4 is the only copy I have. I have attached a snippet (which hasn't been decimated yet). There is a lot of heat shimmer.

Thanks!

Try something like this:

LWLibavVideoSource("Sting Title.mp4", cache=false, prefer_hw=2) 

TDecimate(Cycle=6, CycleR=1)
src = last

mask =  mt_binarize(180).mt_expand().mt_expand().mt_expand().mt_expand().Blur(1.5)

BilinearResize(width/2, height/2)
QTGMC(InputType=2)
SMDegrain(thsad=1000, tr=5)
nnedi3_rpow2(2, cshift="Spline36Resize")
aWarpSharp2(depth=5)
Sharpen(0.5)

Overlay(src, last, mask=mask)

Thanks Jagabo, that looks great.

I can't get SMDegrain to work. I got it from here:

http://avisynth.nl/index.php/SMDegrain

to here:

https://htmlpreview.github.io/?https://github.com/Dogway/Avisynth-Scripts/blob/master/...SMDegrain.html

to here:

https://github.com/Dogway/Avisynth-Scripts/blob/master/SMDegrain/SMDegrain.avsi
(I assume I have to put the text into a file and make it an AVSI).

I'm not getting any errors with the AVISynth Info Tool.

Here's the error I'm getting:


[Attachment 72248 - Click to enlarge]

I'm on AVISynth Plus 3.7.2. 64bit.

Edit: looking closely at that line 262, it looks like it wants AVISynth+ 373. Is there such as thing? The latest version available on Github is 372.

That version of SMDegrain (4.4.0d) is working for me. Version() reports AviSynth+ 3.7.3, 64 bit. I don't remember where I got it. A quick search doesn't seem to find it.

3.7.3 changelog: https://avisynthplus.readthedocs.io/en/latest/avisynthdoc/changelist373.html

Or try another temporal denoiser like: MCTemporalDenoise(settings="high")

Thanks, I'll do some sleuthing.

Found that the 373 is still only in beta:

I assume the + sign is inadvertently missing on the 371, 2 and 3 versions?

I found I had a SMDegrain in my collection from 2020, so used that and it works a treat; 14fps, I'll have to get out my whip, I think!

It came out really well Jagabo, thanks again for the code. Tiny bit of black bordering but not noticeable to the plebs.

Thanks for the link. FWIW, the version I'm currently using is "Avisynth+ 3.7.3 test 9 (20230316 - r3961)".
