Both take a bit of time to figure out, but i think Camtasia overall is better quality. Ill leave the rest to you. Good-Luck.
Edit:
1. photobucket lets you upload videos. you can keep it private and then make a read-only password. give this read-only password to whoever you want to see the videos and they can access your photobucket album but cant make any changes to it
2.
Go to YouTube and register for a free account, then click "Upload." Click "Browse," select your video, and click "Select." Fill out the form with a title and description for your video, then click "Upload."
Click on your account in the top right hand corner, then click "My Videos." Select "Edit" next to the video you want to make private. Scroll down and choose the private option beneath "Privacy" then click "Save Changes."
