Why is iMovie not recognizing video on your camcorder?

iMovie may not recognize video from your camcorder due to incompatible file formats or codecs that the software does not support. Additionally, ensure that the camcorder is properly connected to your computer and that it's powered on. Check if the video files are stored on the camcorder's memory card and not on a locked or inaccessible section. Finally, make sure you have the latest version of iMovie, as updates may include support for new formats.
