Extend the Videos API via a "metadata" endpoint, that provides additional data about the video.

Including but not limited to

• Category changes during the video
• Offsets are relative to the source video that the video is from. So for a highlight it would report the video it was cut from and include where in the origin file the highlight is cut from.

For Example: https://api.twitch.tv/helix/videos/metadata?id=1234
Metadata would support up to 100 (or 50) id's at once like Get Videos

Returns examples

A video of type archive
{
"data": [
{
"id": "1234",
"duration": 18000,
"chapters": [
{
"offset": 0,
"gameid": "200"
},
{
"offset": 500,
"gameid": "220"
}
],
parent: null
}
]
}

A video of type highlight
{
"data": [
{
"id": "1235",
"duration": 600,
"chapters": [
{
"offset": 300,
"game_id": "200"
}
],
"parent": {
"offset": 200,
"id": 4321
}
}
]
}

Use cases:

• if we present a highlight on a third party website, when the video is complete, we can present a easy way to go to the next Highlight in the series (where highlights are cut sequentially) or easily link to the original stream archive for continued watching.
