# Preservation Strategies ## Preservation Preparedness The following measures, presented in order of increasing ambition, will help ensure long-term access to 360-degree video and prepare for future preservation interventions: ⭐ **Level 1:** * Archive a copy of the **360-degree video file** in a suitable [preservation format](/pimkb/preserving-360-video/video-formats.md). * Ensure **documentation** has been captured describing the video format, including projection format and mono/stereoscopic. 🌟 **Level 2:** * Ensure **spatial metadata** has been injected into the file, including the projection format and mono/stereoscopic format used. * **Identify and test** suitable 360-degree **video player software**, via [XR hardware](/pimkb/preserving-xr-hardware/head-mounted-display.md). 🌠 **Level 3:** * Archive a copy of the **source video files** (pre-stitching), production/project files and any dependencies required to access these. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
