AVI, the most commonly used video format, is not fully compatible with some video editing tools such as the iMovie, Final Cut Pro (FCP), and Final Cut Express (FCE) perhaps because AVI is Microsoft's response to Apple's QuickTime technology. Sometimes we may get some wonderful AVI video files, shot by ourselves, or shared by friends, and we may prefer to make it a fancier or more meaningful one by editing them with iMovie or FCP, but find it impossible because of the reason mentioned above. What can we do in this case?
Well, as to my personal experience, I may safely draw a conclusion that the best solution to this problem is to change the video format from AVI to DV, and that to convert AVI to DV with no quality loss at ultrafast speed for editing on iMovie or Final Cut Pro, you’d better look for a solid and intuitive Video Converter for Mac (Video Converter for Windows).
Free download a third-party video converting tool and install it. (Recommended product: Doremisoft AVI to DV Converter for Mac)
Simply click "Add Files" icon, and then locate the original AVI files from the folder you kept them and import them to the converter. You can add several files at one time for there is a build-in batch conversion function.
Move your mouse to the menu bar of "Convert to" and hit it, then choose "DV-Digital (*.dv)" from the "Common Video" tab as the output video format.
Press on the big blue "START" bottom on the right bottom, and leave the professional converter to finish the rest for you. Thereafter, you can easily import all the converted file to iMovie, Final Cut Pro, Adobe Premiere Pro and so on.
