Lightroom imports many common digital video files from digital still cameras, including AVI, MOV, MP4, and AVCHD. You can preview video clips in the Loupe view of the Library module, scrub videos, set poster frames, and more. You cannot, however, open videos directly from Lightroom into Photoshop.
If you edit the metadata of a video file in the Library module, the changes are stored in the Lightroom catalog. The information is not available to other applications. You cannot see or edit the video camera’s capture time in Lightroom. For more information about the limitations of working with video in Lightroom, see Video support.
