How do I purchase quicktime 7 pro?

As Niel states, it's no longer sold. However, if you purchased a license in the past, you can still install it and use the license code to enable Pro features (at least I know that I have done so in El Capitan): Download QuickTime Player 7 for Mac OS X v10.6.3 or later

If that is not an option for you, then I would recommend instead purchasing inexpensive editing software like Adobe Photoshop Elements or even trying the export options of VLC (http://www.videolan.org/vlc/index.html).

You can’t. Apple no longer sells it.

I own a license from the past. QuickTime 7 Pro is not accepting it. Had I known in advance, I wouldn't have "upgraded" to Sierra. What a shame.

My Pro license continues to work in Sierra.

I wish to purchase the QuickTime Pro. any clue as how I would go about that/

I purchased a license for Quicktime Pro 7 back in 2005. I just upgraded to Sierra 10.12.5. I entered the license key and it immediately turned on the Pro features. I would suggest you try again.

Thanks

I had to redownload Quicktime 7 on my new Mac. But when I put in the pro license it does not go through. I will call Apple tomorrow.
