Avi file which was encoded by Mencoder is not recognized by portable dvd player

[haneulso]

I want to convert video files to play it by portable dvd player.

I will use this command.

"mencoder foo.avi -ovc lavc -oac mp3lame -o foo2.avi -ffourcc XVID"

The problem is video image size.

My player cannot play a file which has image size over 720x480.

But, some video image size of my video files are over 720x480.

I want to downsize its image size without change of resolution ratio.

How can I get this?

In summary, how can I downsize video resolution without change of resolution ratio.

Hi haneulso,



mencoder foo.avi -ovc lavc -oac mp3lame -o foo2.avi -ffourcc XVID

There is the easy way that I always used when I was more of a MEncoder fan. The following sets the horizontal size to 720 while allowing MEncoder to set the vertical size based on the aspect ratio:


mencoder foo.avi -vf scale -zoom -xy 720 -ovc lavc \
-oac mp3lame -o foo2.avi -ffourcc XVID


Hope this helps?

Hi haneulso,

Thanks. It work great.

Good news! There are many other little extras you could add to that command line but if you are happy with the result I reckon stick to that :-).
