Use the logging features in Adobe Prelude to create subclips, and add temporal markers. Temporal markers contain data about a specific portion of the movie clip. To add static metadata to the clip, use the Metadata panel.
The logging information and the added metadata are captured in an XMP file. For some formats such as QuickTime (.mov) the XMP information is written into the media file. For formats that don't support writing to the media file, like MXF, the XMP is written into a sidecar file. The sidecar file is stored at the same location as the media file.
