You have a requirement to detect and track a person's movement.
You use the detect function in Video Indexer to determine multiple instances of the same person appearing in multiple shots of the video.
When you see the insights of your video, the observed people tracing feature shows up on the JSON page with all detected people.
Review the JSON given below and select the answer choice for the missing keyword in the JSON output:
"insights": { "observedPeople": [{ "id": 1, ".....................................": "560f2cfb-90d0-4d6d-93cb-72bd1388e19d", "instances": [ { "adjustedStart": "0:00:01.5682333", "adjustedEnd": "0:00:02.7027", "start": "0:00:01.5682333", "end": "0:00:02.7027" } ] }, { "id": 2, "".....................................": "9c97ae13-558c-446b-9989-21ac27439da0", "instances": [ { "adjustedStart": "0:00:16.7167", "adjustedEnd": "0:00:18.018", "start": "0:00:16.7167", "end": "0:00:18.018" } ] },] }
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: C.
Option A is incorrect because thumbnailVideoId provides the ID of the video from which the thumbnail was taken.
However, we require the video's thumbnail ID.Option B is incorrect because accountId provides the video's account ID.Option C is correct because it provides the video's thumbnail ID.
The Observed People Tracing will show up on the JSON page with all detected people's thumbnails.
You can choose a thumbnail of a person and see where the person appears in the video player.
Option D is incorrect keyFrames provides a list of keyFrames within the shot.

To learn more about tracing people using Video Indexer or Video Analyzer for Media, use the link given below:
The JSON provided contains information about the observed people in a video, along with the instances in which they appear. The missing keyword in the JSON is the key that uniquely identifies the video being analyzed.
Based on the JSON provided, we can see that the video is being analyzed for people's movements and their instances. The 'observedPeople' object in the JSON contains an array of objects that provide information about the different people detected in the video. Each object contains an 'id' that uniquely identifies the person being observed and an 'instances' array that contains information about the instances of that person appearing in the video.
However, the missing keyword is not related to the observed people or their instances. Instead, it identifies the video being analyzed in Video Indexer. Without this key, it is not possible to link the observed people and their instances to the specific video in Video Indexer.
Let's take a closer look at the answer choices:
A. thumbnailVideoId: This is not the correct answer. A thumbnail is a static image extracted from the video, and it does not uniquely identify the video being analyzed.
B. accountId: This is not the correct answer. An account ID is a unique identifier for a Video Indexer account and is not related to a specific video being analyzed.
C. thumbnailId: This is not the correct answer. A thumbnail ID is a unique identifier for a specific thumbnail image extracted from the video and does not identify the video being analyzed.
D. keyFrames: This is not the correct answer. Keyframes are static images extracted from the video that represent significant changes in the scene. They do not uniquely identify the video being analyzed.
Based on the above analysis, the correct answer is not provided in the answer choices. However, the missing keyword should be a unique identifier for the video being analyzed in Video Indexer. Without this key, it is not possible to link the observed people and their instances to the specific video in Video Indexer.
