Time-lapse DV capture - how to?

I want to capture video from my GL2 to my PC over Firewire. The necessary connections are made, but none of the software I've tried lets me capture at a reduced frame rate. I want to capture for a long time at perhaps 0.5 fps, and the only options I've found to let me do that are only available for analog capture.

Is there some (preferably free) software available that does this in a straightforward way? I'd think it would not be difficult.

Thanks! :)

If you use a mac, istopmotion from istopmotion.com.
Or you could capture all of it and accelerate later, depending on what editor you use.

I don't use a Mac, and I don't have the disk space for so many hours of 30 fps video. Surely us Windows users are not without a solution for this sort of thing?

Meanwhile, I've embarked on a project to try to write a program myself that does what I need. So far, it can capture, but only at 30 fps! :-p Thankfully, Microsoft's DirectX SDK is fairly easy to get started with.

John, I should preface my comments by saying I haven't actually done this, but I own ScenalyzerLive! (a wonderful product) and it will allow you to capture in time lapse. It's about $40 USD.

Depending on what NLE program you are using, they also might allow it. My older version of Premiere does (version 6: 6.5 allowed it too). I'm pretty sure they took it out of Premiere Pro, though--but then, I have ScenalyzerLive! now, so it's a moot point. I use it to capture most of the time, especially when I have a ton of clips to do.

I think Premiere can do stop motion though firewire, and time lapse.

Cheers,

Ed

I think I was not entirely clear. What I want to do is to avoid using tape entirely--I want to record direct to disk via the Firewire connection. I know Scenalyzer will capture from tape with time lapse, but will it capture directly to disk that way?

And what about Premiere? I have access to Premiere Pro, but I too think that it lacks this feature.

Thanks for the replies--I'm still looking for more.... :-)

Premiere 6.5 has Time Lapse and will record direct to the hard drive. You are correct that Premiere Pro does not have this:

Doesn't the GL2 have a time lapse feature built into the camera?

XP PowerToys

This may be too basic, but there is a free Microsoft download from their powertoys website

http://www.microsoft.com/windowsxp/pro/downloads/powertoys.asp

For a "webcam timershot" program. I don't know if it's USB only, haven't tried it myself, but it's worth a shot

John, you got me curious so I sat down and tried this to make sure it works. I have used Premiere 6.5 to do this in the past. John Britt's post describes it well.

Scenalyzer will also do time lapse capture directly from the camera.

Setup: put camera on tripod. Take out tape. Plug one end of the firewire cable into the camera and the other end into the PC. Turn on camera (in camera mode, not VCR mode).

Start scenalyzer. File | Capture.

Click the "time-lapse capturing - capture only one of N frames" box. Enter a number in the box. For half a frame a second that would be 60. Click OK. Now when you click capture, scenalyzer will capture directly from the camera into a file on the hard drive. It will only capture a frame every other second. Works great.
