Need Help On Video Conversion With Media Coder

I am Arul, a new user to Media Coder software.

I am intended to convert the swf files to video files like .avi, mpeg etc.

I can able to get the conversion, that is what I wanted to get.

But the time duration of the output file is very smaller than the input file.

I want to have the output video file same in input swf file time duration.

My head is spinning. Need help to fix this problem.

If any one working with media coder
