I have Video Pro X 14. Where can I get special effects plugins? As far as I know I have none. Do any come with the program? And, can I use third party plugs?
If you got it as part of the HumbleBundle offer then no, you probably don't have any additional third party effects. At least that is how I read the offer on the HumbleBundle website. Third party effects are normally only offered via a direct purchase from Magix as a promotional deal. If you had any and still have your Movie Edit Pro 15 on your system they should have shown up in the effects section. Look for OFX effects plugins and check with the company's websites for compatibility as they normally list the programs their plugins will work with as some OFX plugins do not work with Magix products.
You will be able to upgrade at the reduced upgrade price to the newer version which will contain whatever plugins are on offer at the time, once your program is registered.
