This is a reminder for myself, I will try and make a video later
that is clearer, with more steps.
How too;
Create Free HD Videos for Youtube.
If this Video is available , go to the link below and watch. 
 It is from a user who calls himself
gigafide and all of his tutorials are very good, 
so go to the link below.
What I did per instructions was to download MPEG Streamclip 1.2 
 followed the setting in the video above, also need to download a
 converter called FormatFactory 2.10 this is incase you
get the messeage that your file can't be coverted.  to convert
to mp4 with formatfactory, file, export to mpeg4 and then load
your video into the Mpeg streamclip 1.2
May God richly bless and keep you, sincerely,
