Some embodiments provide a method of capturing digital video. According to this method, the digital video is received at a first rate. The received digital video includes metadata. The method uses the metadata to store the digital video at a second rate that is different from the first rate. In some embodiments, the first rate is an encoded rate, while the second rate is the digital video's native shooting rate (i.e., the rate that a camera originally shot the digital video). The digital video's native shooting rate can be any arbitrary rate up to, but not including, the encoded rate. Examples of the second native rate include (1) 24 fps for an encoded 25 or 30 fps video stream, (2) 30 fps for an encoded 60 fps video stream, (3) 42 fps for an encoded 60 fps video stream, etc. Some embodiments provide a method of outputting digital video from a computer. From a storage structure of the computer, this method retrieves a video clip. In this video clip, the method embeds a metadata structure and records a set of metadata in this structure. The method then outputs the video clip with the embedded metadata. |
