For TV export, MPEG codec is used and for this royalty need to be activated.
There are 2 ways to activate royalty :
1) If you are connected to network, then, royalty would be activated automatically.
2.) If automatic is not working,then, you will be prompted for offline royalty activation as shown below :
Copy the serial number and go to mentioned website and paste code shown in Unlock key and click on OK.
What are the details of this "feature"? I have never heard of this. Is it for commercial TV or to play on my own TV?
MPEG2 is the encoding method used for television broadcast and DVD's, while MPEG4 is primarily applied to portable devices and Internet sharing.
Some TV's only support MPEG2 codec to stream but nowadays both MPEG4 and MPEG2 are recognized by TV.
Difference between the 2 depends on file quality and file size.
MPEG2 has high quality which in turn increases its file size whereas MPEG4 is a better compression technique which reduces file size and is not par with quality if matched to MPEG2.
Refer to below link if royalty activation is failing on your system
Since I don't see using this "feature", how do I turn it off?
