What it does

Snipstream turns a long video into a short 20-second clip, with the most important information.

How it works

Extracts subtitles from a YouTube video.
Uses Microsoft Cognitive Services API to find key phrases from each sentence.
Gives weight to sentences according to density of key phrases in each sentence. This means it picks out the snappy sections which are the most important.
Stitches these sections together to make a 20-second snip.

Use cases

Turn long lectures into quick refreshers for revision.
Watch the highlights from political debates.
"Trailer" preview for longer YouTube videos to see if you want to watch them.
Many more...

Future developments

Customisable summary length.
User-defined focus for the summary.
Integration with speech to text software to summarize any video or audio.
