GenMotion and DePan plugins for global motion compensation

So, source Depan code is released today. But it was my first plugin, and probably the worst code ever written

Well, it's the best stabilizer for Avisynth and I got it perfect working now! After many tests, I have found that correct levels for the base clip are very important. So I'm feeding DePanEstimate with a special tweaked clip. I'm using colorUYV(autogain=true) for this. ColorYUV(autogain=true) is often wrong, but it works very good for DePanEstimate().

The trust parameter is very important too. It sets the scene change detection.

I have tested this on many different clips and the result is almost always 100%, with trust=1.5.

I will upload my new stabilizing script here today.

Fred.

I just discovered this fantastic plugin and it does wonders for my digital camera movies! by just cropping 20 pixels around I get a much more stable picture on many of my movies!

I use the following for some of my canon camera movies

loadplugin("C:\Util\canon2mkv\ffms2.dll")
FFVideoSource("c:\full-path\MVI_9766.avi") 
loadplugin("C:\Util\canon2mkv\hqdn3d.dll")
loadplugin("C:\Util\canon2mkv\DePan.dll")
loadplugin("C:\Util\canon2mkv\DePanEstimate.dll")
i = ConvertToYV12()
mdata = DePanEstimate(i)
DePanStabilize(i, data=mdata,method=0,dxmax=20,dymax=20,rotmax=0)
crop(20,20,-20,-20)
hqdn3d()

Hmm, i don't undestand why, but blur in DePanStabilize 1.101 not work for me.
Made it any size from 10 to 150 and don't see any difference

vectors = MSuper().MAnalyse(isb = false,blksize=8, overlap=4,search=5)
globalmotion = MDepan(vectors, pixaspect=0.911, thSCD1=500)
DepanStabilize(data=globalmotion, cutoff=0.5, mirror=15,rotmax=5,prev=0,next=0,blur=50, pixaspect=0.911,subpixel=2,method=1)

SSH4,
sorry. Blur is not implemented for rotation in current version 1.10.1.
Try MDepan (..., rot=false)

Also I discovered, that blur was accidentally not implemented at left side for subpixel=1.
