I'm using a camera to record avi files. When I play the file in any media player, will it always play at precisely the same speed as how the events happened in real life? I need to know exactly how much time passes during the event(s), that's why I'm asking. Help much appreciated!

Thanks
 
hmm alright, thanks.

How are avi files made, anyway? Is there anything in the file which tells the computer at what framerate it's supposed to play the video?
 
I've gotten my 0-60 times in cars using captured video. Most editors have timelines that'll show you how long the video is.

And your second part, I don't quite understand what you're asking, but at least 30FPS is required for smooth playback. Standard TVs run at 29.97FPS(basically 30FPS, just interlaced) Anything less is obviously choppy.
 
Well, isn't a video made up of a bunch of separate images? That's how a camera works, right? It takes separate pictures in rapid succession. Therefore, doesn't that mean that a video file is made up of a bunch of separate images (frames) stored together in the .avi file (or whatever extension it is)? That's how I understand it works, anyway. So if what I said is correct, how does the computer know how fast to play the frames in order to achieve the same speed of playback as they happened in real life?
Does that make sense?

Also, what do you mean by editors? Like what's an example?
