This isn't an embedded video you can mark up. It's a book that borrows a video, and the dependency only runs one way.

Video Book joins a video's caption lines into paragraphs and chapters, and saves them as an EPUB. In Backchat every paragraph keeps its time: tap one and the video plays from there while you read, highlight and write in the margins.

If the video disappears, the text, the times, and every highlight and margin note are still there. Only playback stops.

You own the words you marked up; we are just renting the audio.

Backchat is never about ownership of the source material: we have limited time on this earth, and at most, we will watch a video a few times.
0:46
Backchat puts the ownership in the durable asset: the margins, the marks, the value we extracted. That is what is supposed to last.
No timestamps found yet.
Every caption line needs its time in front of it, such as 0:00, 1:02:15 or 00:01:02,500.
