Steady Hand with letterbox

JJKizak wrote on 10/12/2002, 10:13 AM
Using Dynapel Steady Hand on letterbox shifts the entire letterbox
frame up and down in the black with the horizontal correction checked.
The jerky movements are corrected but they are transferred to the
black areas above and below.
If unchecked it is fine but there is no correction in this plane.
Is there a way to apply upper and lower black correction in VV3?

You will probably need to make a mask to recreate the black areas. You could try using Cookie Cutter effect.

By far the most effective way I have found of using SteadyHand is to click on the "No Edge Correction" radio button. I can take my steadied avi file back into VV3, and can use the powerful Event Crop tool to crop as much as needed to eliminate the black border.

If I let SteadyHand do the zooming, then I lose control of just how much zooming is necessary. If it zooms too much, I lose resolution unnecessarily, and if it zooms too little, the resulting video shows big "clunks" where the zoom window was bumped by the black border.

If I need a lot of steadying, I use a large "Correction Range" in SteadyHand, up to the limit of 1667ms. The problem then, of course, is that the black borders can be huge. If I want just a little smoothing, I use a much smaller range, such as 333ms. Then the borders are much smaller, and I don't have to crop as much in VV3. I thus don't lose much resolution.

Better to have perfectly smooth shots in the original avi, but for those that aren't, the combination of SteadyHand and VV3 saves the day.

One of the great things about this forum is learning "stuff".
What is SteadyHand? Is it a camera setting or a software plugin or program?

vicmilt, try http://www.dynapel.com/private/sh_overview.htm. I just bought it and although it reduces resolution it definitely saved the day for the last wedding I filmed without a tripod. My back was killing me and there were a lot of sways and slight jerks that are now smoothed out or completely gone.

Again, the secret is to let SteadyHand do the smoothing, but use VV3 for the zooming. That way, you can go through the steadied avi footage and use the excellent VV3 zoom keyframing to zoom just enough to hide the borders, but not so much as to kill any resolution.

There are quite a few discussions on this forum about SteadyHand. Do a Search for it by name.

riredale, I took your suggestion and after SteadyHand, used track motion -- a far superior way of doing things! Thanks for posting!

I use SteadyHand a lot, but many times I am not happy with the result.
With me, SteadyHand has the bad habit of "jagging" vertical lines. For example, if my original has a lamp post in the distance, in the end product I get a vertical jagged line, quite noticing (and unpleasant). The same happens with lines separating areas of diferent color (for example, the edge of a wall against the sky).
I work with PAL AVI's 720x576
Anyone seen this ? Solutions ?
Thanks.

I get the same thing with steady hand, to the point where I find it pretty useless!
It works great with images that are bound for streaming, however when you want to use it for VHS tape or SVCD the results are shuttery and in most cases worse than the original shake.

Nope, I've never seen such an effect over on this side of the Atlantic (in NTSC-land).

Why don't you contact the company either over the phone or via email? I think they're located in NY.
