Very long AVI to mpeg

[Sparkydjm]

Hi!
Wondering if someone can help.

I have a recording (approx 24hrs long In short AVI segments) that I want to combine into a short movie. Say around 3 mins long. It will look almost like a time lapse film.

Unfortunately I have no idea where to start, I have looked at some AVI to mpeg converters but want to make sure it will do what I want before I buy.

Any pointers would be appreciated, I'm sure I will be back with more specific questions once I have the basic's.

Thanks

Darren

Avisynth is probably the simplest way to go. A basic script like this

AVISource("video.avi")
SelectEvery(nn)
AssumeFPS(30000,1001)

Where nn represents the interval between frames that you wish to keep. To strip 24 hours of footage down to 3 minutes you would have to set nn to be 290, or one frame every three minutes (give or take). You then feed this script into virtualdub, and encode the result.

To strip 24 hours of footage down to 3 minutes you would have to set nn to be 290, or one frame every three minutes (give or take).

How did you work out those numbers?
By my calculations, 24 hrs down to 3 mins requires nn=480 (24*60/3).
That gives a frame roughly every 16 seconds (480/30) of the original.
(Even with n=290, it would be about every 10 secs, not every 3 minutes.)
