Clipstart recognizes most digital still cameras, USB-based video cameras, the iPhone 3GS, and the 5th generation iPod Nano. When connected, the "Import from Folder" button in the tolbar will be replaced with the name of the camera (or inserted SD card). Press the "Import" button to see a preview of movies on the camera and optionally apply a tag to them before importing.
Clipstart should recognize most cameras directly connected with a cable. If your camera does not show up, try taking the SD card out and using a USB or FireWire card reader so that Clipstart can access it.
If a video has already been imported, Clipstart will notice that it's a duplicate and offers to skip it. It prompts after all videos have been imported, so that you can review the duplicates all at once. Clipstart never deletes videos off of the camera if they were duplicates, since in very rare cases Clipstart might think a file was a duplicate when in fact it was new (Clipstart uses a combination of original filename, modification date, and file size to detect potential duplicates). To clear remaining videos you can delete them from your camera outside of Clipstart, using the camera directly, the Finder for mounted volumes, or the Image Capture application that comes with your Mac.
See copying and file locations for more information about where imported videos from a camera are stored.
