I recently got from a car boot sale a very good video 8 camcorder.

I can turn its output, through the Aldi tevion dvd creator-capture-usb gizmo into very good mpeg's avis, dvd or what have you.

But this camera doesn't have built in steady feature

So need software to do this that is free ...that is get rid of all the jitters and shakes in the pictures in the Avi's mpegs etc once created......I've looked ...all that i can really find is something that works with virtual dub ..i don't want that, i don't like virtual dub ..and i want a standalone prog that is easy to use.

or guidance on what alternative names there are for the software I need.

google seems to bring up a load of mobile phone crap

others Ive seen come as part of a package ..eg adobe premier elements ..

ps premier elements dont work cause i dont of SSE2 or something or other capable computer

I have all the video editors I need .I just want a stand alone video de-shaker ..

don't say buy a cam with this built in ..........as I can vouch for this cam:- it is very very good with all accessories decent batts...........and cost me the grand total of 5...

thanks in advance for advice.

all the best.markj

no ..I want software to correct the avis etc

name of the game is to spend as little as possible

Vreal will do software image stabilization. It works extremely well. It als has a mode were it scans forward and backward through the video, and does essentially video image stacking -- greatly increasing the effective resolution, and reducing the image noise.

http://www.vreveal.com/video_demos

It's GPU accelerated if you have a G80-class Nvidia graphics card, but will run on any PC hardware (just slower).

There's a free version for download, the "premium" version is only $39. Highly recommended:

says sorry your cpu is not suported

mine is an amd 3000+ 32 bit

We do a lot of video work because of our horses. I use ProDad's Mercalli program to stabilize my video if required. It is not free but it is reasonable.

Mark,

You will obtain far better results if you stabilize the camera in the first place. It doesn't cost hardly anything to build a balance weight stabilizer. With mine I can take hand held images with a 400mm telephoto.

Even just bolting the camera to a longish steel rod will make a big difference. Anything that you can do to increase the weight and the polar moment of inertia will make a big difference.

Evan, what caliber is that rifle and did you build the silencer yourself?

It is a 35mm Canon!:) ***

That lens is an old very sharp Japanese made lens. It has the minimum of elements and is very fast. Combined with the 2/3rds frame size of the 300 and 350D cameras it is equivalent to a 600mm lens.

I tried the vReveal video stabilizer software. It does work but not quite so well as their advertising hype would have you believe. My system is maximally equipped to make best use of the software with an Nvidia Cuda enabled GPU with a gigabyte of DDR3 ram and a dual core AMD 3000 CPU with 4 gigs of ram.

It does smooth out the shakes somewhat but is no substitute for a stable camera. If combined with a steadycam mount of some sort it might be a useful adjunct for handheld shooting.

well no stand alone yet ...prodads an add on for

Adobe Premiere Pro, CS and Elements
Avid Liquid
Canopus Edius
Pinnacle Studio

suppose i will just have to wait until i get my 64 bit computer fired up

all the best.markj

This is an interesting thread. Thanks Lazlo for the link. With a bit of google fu, I realized the work done by this package is very similar to work I need to do for a problem I'm working on in my day job. A reference to published literature in the Wikipedia article on super-resolution imaging then sent me to some very useful stuff. Since the cited references in Wikipedia reference parts of the literature I know well, I can say with fairly high certainty that once again, a technical article in Wikipedia was not garbage. . .

Sorry about the ProDad recommendation. I use Edius as my NLE. I thought the program was available as a stand alone. Too bad because it works really well.

The reference may not be garbage but the Wikipedia article is.
http://en.wikipedia.org/wiki/Super-resolution

It is riddled with errors. For instance it states "Single frame SR methods attempt to magnify the image without introducing blur."

This is nonsense. From one of the references cited by the same article describing single frame super resolution:



Example-based SR has been shown to exceed the limits of
classical SR. However, unlike classical SR, the high res-
olution details reconstructed (“hallucinated”) by example-
based SR are not guaranteed to provide the true (unknown)
high resolution details.
http://www.wisdom.weizmann.ac.il/~vision/single_image_SR/files/single_image_SR.pdf


In other words, the Single Frame Superresolution technique is providing an image that looks like the original but isn't since the details have been synthesized independently of the actual image. It's a fake.

Then there is this statement:


A diffraction-limited system contains no aliasing, nor does a system where the total system Modulation Transfer Function is filtering out high-frequency content.


Completely incorrect. At a modulation transfer function that is at the Nyquist limit of the LENS which sets the diffraction limit of the system, aliasing will be 100%. In other words, an on pixel may be shown as off and an off pixel may be shown as on. This is apparent as a moire pattern at an effective frequency of 1/2 the the spatial frequency resolution of the lens.

Systems aren't diffraction limited, lenses are. Systems can exceed the difraction limit by using combined spatial and time domain techniques, aka synthetic aperture. A lens is constrained to spatial domain only and cannot provide information above the Raleigh Limit, ever.

There is more but this is enough, once again, to make my point. This is the sort of thing they teach lowly Photocopier repairmen.

The answer doesn't need to be much more complicated then this:

http://forums.steves-digicams.com/attachments/hybrid-still-movie-mp3-digicams/125260d1214969176-steadicam-small-hybrids-interested-pict0019-small-2-small-small-.jpg

to get a lot of relief from camera shake. What good does it do to have software smooth the image out at the expense of detail in the image?

The handle of the pictured device rest on a ball like connection. The long shaft simply balances out the camera.

ALL THAT SAID, AIN'T NO EFFECTIVE REPLACEMENT FOR A TRIPOD. If you use a tripod, turn the camera on and don't touch it while shooting. Most tv newsphotographers carry $5,000 tripods and my own personal Gitzo for my stills is $1500.00. Good sticks make you look better.
