[M4IF Technotes] ISO compliant video sequences classification

[Rob Koenen (M4IF)]

Thanks Zhenzhong.
One more remark:
> > "ISO compliant Class B Clip - High spatial detail and 

There is nothing about these clips that is "ISO compliant".
There were selected and used by MPEG to develop MPEG-4, and
that's all there is to these clips.
