Hello,
if I have *.png files, then how to generate an .avi out of it? With 25 fps.

man mencoder
The -mf option is the one you are looking for.

I used this :
mencoder mf://E:\Pov\road\anim\*.png -mf w=800:h=600:fps25:type=png -of
mpeg -ovc lavc -lavcopts vcoded=mpeg4:mbd=2:trell -o
E:\Pov\road\anim\road_parametric5.mpeg
(this is rather low bitrate)

There is no option tu set the bitrate, you get whatever the default would
be. Furthermore, you put very few options to increase the efficiency of the
encoding. I personally use the following settings:
-ovc x264 -x264encopts
frameref=8:bframes=2:8x8dct:me=umh:subq=7:nodct_decimate:trellis=2:weight_b:direct_pred=auto:crf=20
The crf option is the overall quality.

Actually, you can set the bitrate according to the man page - it's part
of the lavcopts parameter, probably depends on the codec used.

Agreed over the few options - but I just wanted to show a simple
example, to help to get started (the documentation of mencoder is not
crystal clear about all these options, personnaly I feel somewhat
confuse...).
Anyway, here is a more complete command I used (note the vbitrate option
btw, so I guess it exists ;-) )
C:\Documents and
Settings\Thibaut\Bureau\Videotools\MPlayer-1.0rc2>mencoder mf:
//*.png -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=4000000:vpass=2:mbd=2:keyint=1
32:v4mv:vqmin=3:lumi_mask=0.07:dark_mask=0.2:mpeg_quant:scplx_mask=0.1:tcplx_mas
k=0.1:naq -mf fps=25 -nosound -o trybest.avi

I believe Nicolas meant: "there is no option to set the bitrate /in
this command-line example/"...
