does the convertfps option on directshowsource blend frames?

I have a 25 fps video that has audio sync isssues. I can solve these issues by using directshowsource as follows...

directshowSource(".....\101.avi", fps=23.976, convertfps=true, audio=false)

My question is... Does convertfps produce blended frames? Or does it simply drop frames?

If convertfps does blend frames, is there anyway to set it so it simply drops the frames (no blending)? I know that blending frames reduces compressibility so I'd rather avoid doing that. Thanks.

It simply drops frames (Avisynth documentation says it quite clear):
Quote:
convertfps = false (in v2.56): When setting it to true, it turns variable framerate video (vfr) into constant framerate video (cfr) by duplicating or skipping frames. This is useful when you want to open vfr video (for example mkv, rmvb, mp4, asf or wmv with hybrid video) in AviSynth. It is most useful when the fps parameter is set to the least common multiple of the component vfr rates, e.g. 120 or 119.880.
