View movies frame-by-frame in QuickTime Player 7

Could you be more specific about what is better about Windows in frame stepping. In all movies I open in QuickTime, stepping with the arrow keys steps forward one frame at a time (the minimum possible). I don't see how any application could step at any less interval unless it is stepping by field (assuming 60 fields per second).

In the case of an application stepping by field, it must do interpolation to create a frame representing 1/60th of a second using 1/2 of the frame information.

In the case of analyzing a golf swing, you really need a higher frame-rate camera. Or, you can use the information in the camera you have (29.97 frames per second/60 fields per second) and create another QuickTime track to create the analysis track. True analysis will require an application which extracts information regardless of operating system.

Any application that understands the video format can extract information for analysis. The QuickTime format allows for saving that information in another time-based track assuming the application understands your need.

If you are not getting the frame accuracy you require check your capture settings. If your capture frame rate is 30 frames per second, most viewing applications should be able to step at that rate.
There are probably more
