lavcopts: (encoder options)
---------------------------
-vqmin 1-31 (minimum quantizer) for pass1/2
- 1 is not recommended (much larger file, little quality difference and
- possibly other weird things)
+vqmin 2-31 (minimum quantizer) for pass1/2
+ 1 is not recommended (much larger file, little quality difference (if u are lucky)
+ and other weird things (if u are less lucky))
+ weird things: msmpeg4, h263 will be very low quality
+ ratecontrol will be confused -> lower quality
+ some decoders will not be able to decode it
2 is recommended for normal mpeg4/mpeg1video encoding
3 is recommended for h263(p)/msmpeg4 (default)
the reason for 3 instead of 2 is that 2 could lead to overflows
