Question

I know that there are differences in different regions of the world regarding the framerate of videos. E.g. a DVD in Europe is in PAL with 720×756 and 25.0 fps. In the US its the NTSC standard with 720×480 and 29.97 fps.
When I don’t want to generate a DVD but a plain video file, e.g. WMV oder AVI what framerate is used in USA? I have a end user application where the user can generate videos, so what framerate does the US user expect it to have? Is there a difference in SD and HD video?

Answer 1

I think 24 frames per second is the de facto frame rate, just because this is the frame rate used in movie theaters, although it shouldn’t make a huge difference.
