Changing FPS on a Video

[pmj0383]

Here is my issue.

We have a DVR recording nonstop at 1 FPS. It's low quality so it can store a ton of stuff and the quality is fine for what it is. When we export the video with the included program, it exports as a quicktime .mp4 and quicktime thinks the video is 30 fps. Long term, we are in contact with the manufactuerer to find out what the issue is. Short term, I need this video to play to 1 FPS not 30, so it doesn't look like it's in fast forward. Quicktime only allows slowing it down to half-speed, and the people that will be watching this need to just be able to click on the movie and watch it, not fiddle around with play speeds. So I what I'm hoping someone can point me to is a program that lets me import a video clip at 30 fps, and stretch it out back to 1 frame per second instead. Thanks in advance.

If the source, by the time AviSynth sees it, is already 30fps, then:

AssumeFPS(1)
ChangeFPS(30)

should do the trick. That first command slows it back down to the original 1fps, and the second command duplicates frames to bring it back up to 30fps, while still playing at the 1fps speed.

You can do similar things using VirtualDub.

Thanks for your help.

I did it with both Avisynth and Virtualdub, worked perfect.
