i need a framerate converter

[snafubaby]

I have an old Intel digital camera that i got back in 1999. It was very low quality, took pics and video, and the video was horribly slow and unimpressive. The framerate was not good. It was almost like i was watching stuff in slow motion, as it was painfully slow and jittery. I recently found a framerate converter online, to see if i could fix the videos that i had saved with that camera. Well, for some reason, the videos would not even load in.

Does anyone know of any framerate converters online, or how about a way to convert framerates of videos?

Any help would be greatly appreciated.

Drop one of the video files into Gspot to see what the format and frame rate is. You can post a Gspot screen shot here. If it's a common format, then it's easy enough to re-encode it and change the frame rate. It may be something like 15fps, which may look 'jittery'.

Most video editors have the ability to change frame rates. But most of them do it by repeating or deleting frames. It won't look any smoother when played back.

AviSynth has frame rate conversion functions that can synthesize in-between frames based on motion vectors. This will give very smooth results but is prone to errors.

A question, jagabo, hopefully not OT for this thread: I had some web cam videos shot at a very low rate, maybe 5fps. Would that AviSynth filter make them a bit smoother by adding frames in between? I know it won't create 29.97fps video from nothing, but the ones I've seen are very hard to watch, so looking for some small bit of improvement.

Yes, that filter will synthesize new frames between the existing frames to convert it from 5 fps to 29.97 fps or whatever rate you desire. It works well when all the moving edges are very sharp and moving linearly. It doesn't work well when motions are very complex. See the video linked in one of the the threads. Watch closely:

The original file is no longer available but I think that slow motion version is 1/10 the speed of the original -- ie, 90 percent of the frames are synthesized.

Thanks, jagabo, I will be experimenting with that.

I'd love to hear how it works out for you.
