What model of camcorder is your video coming from and how did you get it from the camcorder to your computer? What format is the video?
What operating system are you using? Have you ensured you have the latest version of Quicktime, per the program's requirements?
Steve, thanks for your reply
They are coming from various devices but mainly ipads with a format of .MOV.. They are posted to Dropbox. I am using windows 8.1 and have downloaded the latest version of Quicktime.
You'll need to get the specs for these videos and set up your Premiere Elements project accordingly. (MOV is just the package for the files. It tells you nothing of the video specs.)
Open the video files in the free download G Spot or Media Info and post to this forum the dimensions, frame rate and audio and video codecs listed.
