Step 1
Lightroom 4 imports videos the same way that it imports photos, and it will bring in the videos from your memory card while you add your pictures. To start editing, navigate to a clip in Library Mode. (To search only for videos, in the Collections Panel click on the Smart Collection named Video Files—you’ll see all the videos you’ve ever added to your Lightroom catalog.) Type E on your keyboard to see your clip in Loupe view. Then choose the little sprocket symbol to see the trimmable view of your clip.
