Assuming you're on a Windows computer, try downloading Quicktime 7.
The Quicktime Player has a potential vulnerability, so you can browse into the Program Files folder after you install it and change QuicktimePlayer.exe to QuicktimePlayer.old to disable it. But you may well need the other Quicktime components.
That is assuming that your iPhone video files are MOV files.
Thanks for getting back to me.
I am using a windows computer but I'm not too familiar with quicktime nor how to do edit the files in that way.
In addition I'm worried about needing to do this to every corrupted file I have given that I'm working with Hundreds of clips each week...
Can you think of any reason why Premiere elements isn't able to deal with my IPhone videos? I mean Windows Movie Maker 2011 (what I had before this) could do it fine and it is free and quite old. Thats why I'm thinking I'm doing something wrong!
Thanks so much!
I think this may have worked! After downloading quicktime the file not imports without an issue!
That was probably what you meant from the beginning and now I feel kinda stupid!
Thanks so much for your help!
Please mark this question as correctly answered, Sam.
