Using VLC to Capture Frame to Frame Sequence

[pone44]

In VLC for Windows 2.2.4 there are control bar options to:

* set an A-B interval
* advance one frame at a time
* record whatever is playing

I am wondering is there a way to use these controls to record from a specific starting *frame* to a specific target frame?

The A-B interval appears to be based on a *second* rather than on a per frame basis. If you go to a final frame and select the "B" part of the A-B interval, on playback this is ignored and instead all frames that appear in the *second* of time that the final frame appears in are played.

What is the technique here to record from a specific beginning frame to a specific ending frame?
