Hi,

Thanks for all the feedback, I tried the following and get the output below


$ mencoder -fps 15 oldfile.avi -ofps 30 -o newfile.avi -vf harddup
MEncoder UNKNOWN-4.4.1 (C) 2000-2009 MPlayer Team
success: format 0 data 0x0 - 0x90000
AVI file format detected.
[aviheader] Video stream found, -vid 0
[aviheader] Video stream found, -vid 1
VIDEO: [MJPG] 640x480 24bpp 15.000 fps 4205.1 kbps (513.3 kbyte/s)
[V] filefmt:3 fourcc:0x47504A4D size:640x480 fps:15.000 ftime=0.0667
Input fps will be interpreted as 15.000 instead

No audio encoder (-oac) selected. Select one (see -oac help) or use -nosound

Exiting...


Checking the file properties on with SMPlayer on Ubuntu 9.10, it reports 
the audio
information as
Format           85
Bitrate          32kbps
Rate             16000Hz
Selected Codec   mp3

When I have tried various options and managed only to create a new file 
but with no audio.

Can you point me in the right direction

TIA
