mistake importing footage I am kind of new to video (1 year). When I import video footage into Premiere, I sometimes get duplicate clips. Only the long ones. I think I am not importing my footage correctly. Does it have to do with the clip, if it is long, is really spanning 2 clips? The video is HD, mostly those Canon MTS files. What is the correct way to import into Premiere, just started working with CC (2014) version?
It is possible that Premiere is detecting a spanned file and automatically connecting them.  If a file goes beyond 4GB, it may have to be split in to two files due to limitations of the file system used on some memory cards.  It is possible that when you load the file in to Premiere, it recognizes the file was split and puts them back together for both parts that you import.
