[MPlayer-users] mencoder usage help

[Steven Adeff]

Hi, I tried making a Divx video today with the command line you gave
me(except I enabled the audio to be encoded with lamemp3). couple
questions, because the output video quality was quite poor...

1. the mpeg source is interlaced, is there a setting i need to use to
take this into account?

2. the output divx file looked compressed. the original is 480x480 and
when i play it back in mplayer i get the line 

VO: [xv] 480x480 => 640x480 Planar YV12

but when encoding I get this

VDec: vo config request - 480 x 480 (preferred csp: Mpeg PES)
Couldn't find matching colorspace - retrying with -vop scale...
Opening video filter: [scale]
Sorry, selected video_out device is incompatible with this codec.
VDecoder init failed :(

which I don't understand at all...

3. there was lots of artifacting of the output divx file that got
created, what other settings can i try to increase the quality(or is the
only real way to increase the bitrate?

thanks!
