Animation interpolation speed

[Nose Bleed]

Does anyone know the relationship between frames and seconds in animation?



I need a fly through animation to last exactly 176 seconds. I've set the time to 176 seconds, but after it's recorded into mpg format, it's only seven seconds long!



Is there a way to do this accurately, without having to interpolate through 5000 frames?
