Help and Suggestions getting setup

I am in the process of creating a music video for our latest single that has just been released. I have footage in 10 or more video “takes” where I will be editing out 3-20 second clips, some from the same larger take (up to 6 minutes each). I tried to create the short clips in the playlist, however I can’t seem to add more than 8 items in the playlist. Any suggestions how to do this so I can work most effectively and not lose any video quality?

Ok So I have now figured out I can keep adding to the playlist. I guess I’ll keep doing it this way, but if there’s any advice before I get too far into it that might help me out, please let me know. Thanks in advance
