Comment (by wdzierzan):

 I'm using the Media Foundation encoder, and I instructed it to set an fps
 of 20 via MF_MT_FRAME_RATE. Not sure how this ended up as 40 (there's
 something about "half the tick rate" in https://ffmpeg.org/ffmpeg-all.html
 #toc-h264_005fmetadata, but frankly I'm not at all sure I understand it
 correctly).

 I agree an fps of 20 (or 40) is not typical, but I didn't think it would
 matter. Note that the frame durations are consistent with 20 fps.

 I also tried a more conventional frame rate of 30, but this doesn't
 improve things.
