How to save recordings with camtasia

I finished a recording with camtasia! So i got 3options after recording the video which is:
1st:Save and Edit

2ndroduce

3rd:delete

So i tried saving the video in mp4 by clicking on produce the 2nd option! It comes up with .camrec and .avi!!!! Just how would i save the screen recording to mp4 since that option is not showing up, after clicking on produce?
