.IPs dsize={aspect|w:h}
Changes the intended display size/aspect at an arbitrary point in the
filter chain.
Aspect can be given as a fraction (4/3) or floating point number
(1.33).
Alternatively, you may specify the exact display width and height
desired.
Note that this filter does NOT do any scaling itself; it just affects
what later scalers (software or hardware) will do when auto-scaling to
correct aspect.

.IPs "ivtc[=1]"
Experimental "stateless" inverse telecine filter.
Rather than trying to lock on to a pattern like the detc filter does,
ivtc makes its decisions independently for each frame.
This will give much better results for material that has undergone
heavy editing after telecine was applied, but as a result it is not as
forgiving of noisy input, for example TV capture.
The optional parameter (ivtc=1) corresponds to the dr=1 option for the
detc filter, and should be used with mencoder but not with mplayer.
As with detc, you must specify the correct output framerate (-ofps
23.976) when using mencoder.
