MP4 File Export?

[robertLang]

UPDATED -- I go to "ABOUT" and see I have to most recent version.  OK.  I am pretty sure that means I have the most recent version.

I go to support and I see "DOWNLOAD" and I think ?????? WTF is this, but I click yes as perhaps this is a support down load?

Now I see and "Export Video" option.  So I am back to WTF, O????

 

My original post, NOW OBE:

 

I wrote a song, scored it in Crescendo, and then EXPORTED IT as an .MP4 file.  Now, I cannot find the link to export as an MP4.

go to YouTube https://youtu.be/6jF4qD7VXUc?si=470vMVYbmw90tKdx to see the file, sorry about the singing voice, I was very under the weather and eventually dropped this to Bb to lower it.  I do not have a recorded version of that (yet).

Is there an add-on software product I need to buy?  The Mp4 is nice when teaching others to play the song.

 

THANK YOU!!!!!
