    initial v1  
    11I could not get -b:v 150M -minrate 150M -bt 6M to work - still had "bitrate tolerance too small.." [maxrate and bufsize removed]
    22
    3 Increasing -bt: -b:v 150M -minrate 150M -bt 8M was allowed but m2v sequence header says BR = 104,857,200, with sequence length (i.e. # bits/frame) variable, vbv bufsize was 15,138,816. MediaInfo calculated the bitrate as 45.6Mbps.

    5 Adding -maxrate and bufsize: -b:v 150M -minrate 150M -maxrate 150M -bt 8M -bufsize 47185920, m2v seq HDR now says BR=45,142,400, sequence length is constant, vbv bufsize is 13,631,488 and MediaInfo says "overall bitrate 149Mb/s" but Maximum Bitrate is 46.8Mbps

    77All tests on same git as original; and I'm very confused!
