PAW/Frenchy VirtualDub Deshaker plugin

I have been flogging this filter out for a couple days now and the results were OK but not outstanding. I could not get out all the very fast horizontal jitter which looks as if it is zooming back and forth on each end. I was processing NTSC lower frame first scope/letterbox captured from Betasp via MiniDV. The settings for the first pass were other than default::
block size 10-30
scale full
use pixels all
and the second pass:
edge compensation adaptive zoom only
max correction limits rotation 1
720 x 480
NTSC
all others default
VirtualDub: Compressor--MainConceptDV2.1 100%
no audio
The application is very slow even with P4-2.8 with Hyperthreading. In comparison with SteadyHand I prefer the SteadyHand with the following
settings:
zoom to fill
custom settings
rotate "0"
zoom "0"
horizontal "667"
vertical "667"
target window 702 x 468 or larger
Mainconcept encoder 100%
DV mode Lwer field first
type 2
NTSC 720 x 480
7000 bitrate
The default target window will give rock solid results but will move the
entire letterbox picture up and down about 1.5 inches.
It also gives you a lot of those "pac man" clumps of pixelation which with the larger target window become reduced substantially. Deshaker does not have any "pac man" clumps but I can't get the correction that Steadyhand will give.
Since this footage was already telecined by a pro lab this possibly might effect the results I tried just about every combination on the Deshaker but
could not eliminate the horizontal in out (side to side, not up and down).
The footage was a chopper on the ground then taking off and flying overhead.
The SteadyHand followed it perfectly all the way through a sunlight burst whereas the Deshaker had some problems with it. The SteadyHand will also alter the focus somewhat but I did not detect that in Deshaker. I also noticed during the process #1
in Deshaker the top picture was showing some small tiny abberations on some of the mountain background silouettes which showed up in the final clip.
SteadyHand reduced this somewhat in the final clip.
All in all I'm expecting NASA results but I think eventually there will be something new that will outperform these softwares. Perhaps there are some settings that you use that I haven't tried. I'm game.

JJK:

Sorry I haven't responded/posted. I usually acces these forums during my off-time at work, and they have installed new web filtering software which classifies this forum as "chat", so it's firewalled, so to speak, and I can only access from home now, which on my 28.8k copper-line, squirrell-powered connection, is brutally painful (No DSL or cable modem availability in the mountains where we live...

BUT, to answer your question - I haven't used VDub very much (and I haven't used the deshaker at all), so I can't answer your detailed questions - I just knew the website URL. johnmeyer has (apparantly) used Vdub a lot, and my be able to help you out, if you haven't figured it out by now.

Good Luck, and have fun

There is also another product from 2d3 called Steadymove. No one here has tried it yet, but their demos look unbelievable.

See this thread:

Frenchy,
I live in the mtn's too, and no cable, DSL here. I've got a Starband system, and it's HEAVEN! (uploads aren't the fastest, but download screams)

I am about to get broadband - can't wait, tried it out at a friends and almost fainted

JJK, sorry I missed your posts I have been on holiday.

I will try your comparison and re post with how I get on.

You can also try guth at home.se who developed deshaker he may be welcome your input.
