Add media failure - Error: codec missing or unavailable
I am using Premiere Elements 8.1 and I am adding multiple small videos to make one large one. Unfortunately, the small videos are in different formats. Some of them are .mov. Interestingly, some of the .mov videos load with no difficulty. However, some of them don't load and I get the error: codec missing or unavailable.
I am using Windows 10 pro, 16 GB RAM, Processor: AMD FX(tm)-8350 Eight-Core Processor 4GHz
Thanks in advance for any help you can give me.
