 Each data packet represents exactly one encoded frame, and if [version and options requirements](#format) are met, some extra information:
 
-* `keyframe`: `true` if the current packet is a keyframe. Many decoders can decode the video stream without knowing if each frame is a keyframe or not, but some decoders require this information.
-* `pts`: Presentation timestamp in nanoseconds. When rendering the video in real-time, generally you want to present the decoded frames as they arrive to minimize the latency, but this information can be used to remove processing time deviations when [recording](./record.mdx).
