"Most Replayed" Data of YouTube Video via API

Question

Is there any way to extract the "Most Replayed" (aka Video Activity Graph) Data from a YouTube video via API?

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Stoltz

@Stoltz I'm not sure how many more details I can give :/ – Malo

Answer 1

One more time YouTube Data API v3 doesn't provide a basic feature.

I recommend you to try out my open-source YouTube operational API. Indeed by fetching https://yt.lemnoslife.com/videos?part=mostReplayed&id=VIDEO_ID, you will get the most replayed graph values you are looking for in item["mostReplayed"].

With the video id XiCrniLQGYc you would get:

{
    "kind": "youtube#videoListResponse",
    "etag": "NotImplemented",
    "items": [
        {
            "kind": "youtube#video",
            "etag": "NotImplemented",
            "id": "XiCrniLQGYc",
            "mostReplayed": {
                "markers": [
                    {
                        "startMillis": 0,
                        "intensityScoreNormalized": 1
                    },
                    {
                        "startMillis": 2580,
                        "intensityScoreNormalized": 0.7083409245967562
                    },
                    {
                        "startMillis": 5160,
                        "intensityScoreNormalized": 0.6381007317793738
                    },
                    ...
                    {
                        "startMillis": 255420,
                        "intensityScoreNormalized": 0.012864077773078256
                    }
                ],
                "timedMarkerDecorations": [
                    {
                        "visibleTimeRangeStartMillis": 0,
                        "visibleTimeRangeEndMillis": 10320
                    }
                ]
            }
        }
    ]
}

This looks like it works, but how should I read the page it spits out? For example: yt.lemnoslife.com/videos?part=mostReplayed&id=NIJ5RiMAmNs. How should I read that? – Malo

@Malo Look at the "heatMarkerIntensityScoreNormalized" number. 0 is nobody is re-playing and 1 is everybody is replaying. – Avidity

@Malo As heatMarkerIntensityScoreNormalized name suggests, I recommend you to learn more about Normalisation. – Cadence

I have tried to use this API for finding the most replayed part from the top videos by generating the ID of YouTube's most trending videos using the googleapiclient but when I request the API, it returns the item[mostReplayed] as None. Am I doing something wrong with your API as it has worked very well with IDs that I have just manually retrieved from other YouTube videos. – Fontana

@CharlieCook Please provide an example of video id having this issue. – Cadence

I generated a list of the most trending videos' ids: – Fontana

['l-bGkjtMC0Q', 'OLvRv-poMtA', '4R7vRFGJr3k', 'OBsLKLef-F0', 'ar3gEAT2h28', '6ecTO22ulRM', 'J4-lP_D7iEk', 'ZEuV9d3gsio', 'T4CY4wVqhPU', 'v8tR7mPsBcU'] – Fontana

@CharlieCook As we discussed on Discord, your first video l-bGkjtMC0Q does not have public most replayed data (see OP highlighted curve example), hence my API cannot retrieve any. – Cadence

Answer 2

Adding the following snippet to parse/read through @Benjamin's API response. This function will give you the top 5 snippets (peaks) from the video.

def get_peak_rewatched_timestamps(test_data):
    markers = test_data['items'][0]['mostReplayed']['markers']
    sorted_markers = sorted(markers, key=lambda x: x['intensityScoreNormalized'], reverse=True)    
    top_markers = sorted_markers[:5]
    top_timestamps_seconds = [marker['startMillis'] / 1000 for marker in top_markers]
    return top_timestamps_seconds
