1) kewl! does this work in 1-pass ?

2) okay, I'll try to explain it:

- lets assume I have a made bobbed (50fps or 59.94 fps) Video out of my interlaced content.
- this bobbed video gets analysed by deshaker.
- deshaker is creating a (progressive) logfile.

- then I can do my motioncompensation in avisynth with a bobbed video to my wishes using genmotion.

but I want to pass by the first three step. I want to feed deshaker with the interlaced video (thus creating an interlaced logfile), and then want to use genmotion on the bobbed (double framerate, progressive) version of the video.

Not quite the same.

cool = [ku:l]
kewl = [kju:l]

fizick, if your new version of genmotion supports onepass gmc'ing,would this be some kind of master/slave structure?


some pseudoicode:
Code:
one=avisource("one.avi")
two=avisource("two.avi")
x=one.genmotion(analyse=true)  #where x is a variable containing movement information
output=two.genmotion(analyse=false,motiondata=x)
this means, I want to use the motioninformation of video one to move video two.

this is easily possible with the current 2-pass method, but would that be possible with your next version?

I hope it is. It shouldn't be hard, fox example, to have the motion information from the first clip stored in a logfile like deShaker (except the file is generated at run-time).

Tsk tsk! That's not politically correct anymore in Los Angeles, where I am. The correct terms are primary and secondary.

(this is a joke!)

O.K., I release new plugin. It has got name DePan -
tools for estimation and compensation of global motion (pan).
The DePan plugin must replace my experimental GenMotion C-plugin
(which uses motion data from VirtualDub Deshaker plugin log file).
The DePan works in one pass, but consist of server part (function)
and one or more clients parts (functions or its instances).
The server function estimates frames motion data and gives it to client functions on inquiry.

(to SoonUDie: I not quite understand you joke, but decided to use other, safe terminology )

Current version of DePan uses a special service clip as the motion data container.

DePan plugin functions:
DePanEstimate (server) - estimates frames global motion data and write it to special service clip
DePan (client) - make full or partial global motion compensation
DePanInterleave (client) - generates long motion compensated interleaved clip
DePanStabilize (client) - makes some motion stabilization

GenMotion() function is new DePan() function.
Note. The "offset" parameter of DePan() is extended version of "delta" parameter of GenMotion().

Features and limitations of current version of DePan plugin
1. Works only in YV12 color format.
2. Uses only pan motion (no zoom, rotation), but it gives advance in speed and stability.
3. The source clip must be same length as motion data clip.
4. Directly works only with progressive clips.
For interlaced sources, you must use Avisynth function SeparateFields,
with followed optional AssumeTFF, and following Weave (after motion compensation and denoising)
Plugin estimates and calculates motion from one field to neighbour (by time) field (from same or neighbour frame).
5. Not very fast, not assembler optimized.

You may download it from my site (link is on first page of thread).
It has beta (may be alpha) status.
Please, test all its bugs (i know some) and report to here.

There's a typo in the link. It currently says
Code:
http://bag.hotmail.ru/genmotion/depan01.zip
when it should be http://bag.hotmail.ru/depan/depan01.zip

Actually, I use Firefox, and I didn't have any problems... you just have to wait until the download starts on its own (10 seconds?).

Probably, I must make a mirror (what is the recomended for free?)

depan 0.1 has a bug.

depan(offset=x) doesn't work for x being in the range of 1>x>-1
even the info=true screen disappears, if offset is between 1 and -1.

this means depan(offset=0.5) won't work.

thanks!

I'll try that out.

I hope, I can realease some kind of 'smoothpan' standards conversion function (NSTC <-> PAL) within the next days
(will be nearly the same code like the one I coded for morsa's 30p to 24p conversion)
