[Encode2mpeg-users] zoom/crop a 16:9 movie to a 4:3

[Rob <rh...@se...>]

Hi,

I'm having issues trying to convert a movie with the following specs below to 
a movie that needs to fit on a 4:3 screen - 320x240.   I would like the video 
to be zoomed (sides cut off) such that it fits the full screen (no black bars 
on the top or bottom).

This is the command that I used.  It creates the correct aspect ratio, but the 
size is wrong (doesn't fill the whole 320x240 screen).

./encode2mpeg-0.6.2/encode2mpeg -o "D2-sample.24.s06e18.hr.hdtv.xvid-nbs" -avionly -vfr 
1 -encode 2:2:1 -acustom "cbr:br=128" -vf harddup -vbitrate 384 -setaspect 
320 -crop 725:544:0:0 "sample.24.s06e18.hr.hdtv.xvid-nbs.avi"

Close, but no cigar :(

Thanks,
Rob

P.S. encode2mpeg rocks!  :)

This is a bug. Please try this fix and report if it solves the problem.

Edit the encode2mpeg script:
goto line 5129 and add after the line
      ratio=w/h
this line:
      if (sqrt((ratio-a)*(ratio-a)/(a*a))<0.01) a=ratio+sqrt((ratio-a)*(ratio-a))
