some video cameras have this feature. Alternatively some capture systems have it (if the laptop is plugged into the camera) they can control the camera via firewire taking the frames when told to at specific intervals.

If the footage comes from the system itself (internal recording) then this may not be an option.

I assumed 25fps in the above example, I may be wrong, but you will not find it easy to speed up the footage to 750x (my maths may be wrong) normal speed, extracting frames from the original footage is the other option.

Havent done timelapse since I used a super 8 camera though....

What I did John was.

place my camcorder on a tripod in front of a radar screen and let the tape run as per normal, changing tapes a few times. What i was taping was a 24 hour period of radar replay ( we have at Dover , radars that have the image recorded straight to hard drives and kept for years ) . Of course this 24 hour period is sped up normally depending on the time scale set.

So, basically , once all of my tapes are uploaded to my PC to make just ONE file .... my intension then is to speed the recordings up even faster, so that the radar targets will be ZOOMINGGGGGGGGGGGGGGGGGGGGG down the channel.... hopefully from the shots I've taken ( a busy day with lots of crossings ) should make interesting viewing.

Cheers for the advice , anyway
