When I download a video online and convert it to an mp4, using QuickTime, I keep getting a message that stays in the video that it was created using a trial version of Flip4Mac. Why? I purchased QuickTime and the Flip4Mac software came with it. I tried deleting the Flip4Mac portions of it but then I can't convert the files and it says software is missing. Can anyone please tell me what I'm doing wrong? I'm new to Mac as of January and I love it. My only frustration comes when I try to save video files. With Windows I could right click and save easily. With Mac, it's an incredibly difficult procedure (which, I'm sure, is due to my lack of knowledge). It saves files as .afx and I have no idea what that is. I watch a lot of ministry videos that I like to keep on file to watch and share. What's the easiest way for me to save them and be able to put them into iMovie to edit them? I convert the files to mp4, but iMovie doesn't always take them. I'm not the most computer-literate person there is, but I'm not a complete dunce. When I find ways to make it work, it's usually by accident and it's taken me hours to do. Any help or shortcuts would be more appreciated than you could know. Thank you.
