If you use the cvsm you will have yuvfps, that can "speed up" you video.

I would guess that this could work:
lav2yuv video.avi | yuvfps -s 400:1 -r 25:1 | mpeg2enc ...

Where -s is that source frame rate (it ignores the header), 
and -r is the desired output frame rate (PAL example) 
400/25 = 16 * 30sec = 480sec /60 = 8 Minutes.

I hope you have no audio ;)

auf hoffentlich bald,

Berni the Chaos of Woodquarter
