Smoothing choppy pan shot

I'm pretty new to Vegas Infarct I'm only using a trial version of Vegas 10 pro but I'm already very impressed.
I have some old home movie footage that I'm working with, all in all it's not too bad quality but in some of the panning shots seem very choppy, the original source material is just as bad so its not down to settings or a bad capture.
My question is are there any good temporal filters that would help smooth out the choppy pan shots without blurring the footage?

Re: Smoothing choppy pan shot

Define "choppy". Sometimes preview speeds can be slower which might make it "appear" choppy when, in fact, it is not. If you render it out and then play back the rendered file, is it choppy then? Or if you make a DVD, does it appear choppy on the TV?

Re: Smoothing choppy pan shot

I've rendered the scene in question and it still looked pretty choppy, it's not camera shake as such it looks like the frames need to interpolated in order to smooth it out. The rest of the footage is pretty smooth.
The source was VHS and it plays just the same on the TV.
It maybe that nothing can be done to improve it but I was just wandered if there were any filters that may help temporally smooth it out.
I've looked at "Twixtor" but I'm not sure that it is suitable for my needs. Any suggestions would be appreciated.

Re: Smoothing choppy pan shot

If the original plays that way, there's probably not a whole lot you can do. Twixtor will change the speed of the clip. If you want to just try slowing it down or speeding it up and seeing if that makes a difference, just hold down the CTRL key and resize it smaller to speed it up or longer to slow it down.

Re: Smoothing choppy pan shot

You can try playing with the Stabilize feature that's now built into Pro 10.
Right-click on the clip, select "Stabilize Media" and choose one one of the presets.
Go with the default one first and experiment after that.

Re: Smoothing choppy pan shot

If it's home video, I personally would leave it alone and go with it, but that is just me.

Re: Smoothing choppy pan shot

Not certain I understand why you say this. Even if it's a home video you will want it to be as good as you can make it for your home audience. That means trying to correct/eliminate/over-ride defects to allow the home audience to enjoy it as much as possible. Or am I missing something?

Re: Smoothing choppy pan shot

Curiously,

Is it shoppy or stuttery because you shot in 24 or 30 P??

And yes, you can improve by slowing down and applying image stabilization, but you will lose some quality along the way. It also makes pans a little to long so you often end up cutting it down in size as well. If you have to use footage like that then keep the clips short so the viewer doesn't have a long time to dwell on the less than ideral footage.

Re: Smoothing choppy pan shot

If the pan is not essential to the video why not just cut it out. If it is essential for some reason you could make a still shot of the beginning of pan, another still shot of the end of pan and dissolve the two with some commentary to cover the action. I have found that has worked for me over 60 years.

Re: Smoothing choppy pan shot

Well done Leslie. I often make remarks without seeing the humour until later. I remember in one of my films many years ago when I was making a doc. on California red wood trees I mentioned that they survived for many years and whilst a shot was showing of a very old large specimen, I said on the commentary "And this specimen is over a thousand years old". When I first showed the film at a local film club there was much laughter when the shot appeared and it was only then that I realised my then wife was standing in front of the tree. Happy days.
