To be more clear: The variable-bitrate-sample.mov, as found on Google
Drive, is unfixable with a simple ffmpeg command. The files
Jan22016-15*.mov, as delivered in the zip, must be used as input, in
order to not have slow-motion effects.

In really simple terms: Use "-crf" to vary the quality of the
re-encoded video (a crf of 23 is default, lower is better, play with it
to see what is okay for you), at the cost of conversion speed and size.
Use presets to trade conversion speed for file size, while maintaining
the selected quality.
