What happens to your stream

Seven steps, in this order. Where we have a measured number it is shown, with the stream it came from. Where we do not, we say that.

The pipeline

Nothing in it needs chat, and nothing in it needs to know your game.

1Upload
You upload the VOD download from your Twitch Creator Dashboard, or the file OBS saved. We never pull video from Twitch ourselves, because Twitch has no official way for a tool to do that. Twitch keeps a VOD for 7 days on most channels, 14 for Affiliates and 60 for Partners, Turbo and Prime, so download it early.
A 4-hour VOD is about 11 GB. Sending the audio first is planned and not built yet.
2Speech-to-text
Every word of the stream is written down with the time it was said. Loud game audio can cost accuracy, and we have not measured the word error rate yet.
Our test: 12,737 words from a 92-minute stream in 213 seconds.
3Scoring
Two things are measured. First, how you sounded: loudness and speaking pace, compared with your own normal level in the same stream. Second, what you said: an AI reads the transcript in parts and proposes moments that have a hook, a payoff and make sense without context. Each candidate gets a score.
Our test: 33 candidates found.
4Selection, with reasons
A second pass picks the final clips from the best candidates, spreads them over the stream, and writes a title, hashtags and the reasons for each pick in plain words. The clip starts and ends on word boundaries, so nobody is cut off in the middle of a word.
Our test: 5 clips kept. Scoring and selection took 29 seconds.
5Layout of each clip
Each clip is cut to 1080 by 1920 at 60 frames a second. Your camera goes on top and the game below. Face tracking keeps your face in the frame when you lean. A scene change inside one clip is not handled yet.
6Captions
Captions are burned in, one word lit at a time, so the clip works with the sound off. Check names and game terms: speech-to-text gets those wrong sometimes, and you can fix the text.
Our test: the lit word is about 0.01 seconds off the spoken word (median).
7Your review
You watch each clip and read why it was picked. Approve it or reject it. Move the start or the end by half a second and render it again. Fix the title, the caption text and the hashtags. Download MP4 files, one or all. Nothing is posted for you.

Numbers marked as ours come from one run on our test machine. See our numbers for the method and for the results that failed.

What you get

A 9:16 clip of 15 to 60 seconds. Your camera is on top, the game is below, and the caption sits on the seam with the spoken word lit.

0:52:03 to 0:52:30

The tutorial is the best level. Fight me.

A storyboard sketch with an invented example, not real output. Real clips will be shown here when the product is open to the public.

What is not here yet

We would rather list it than have you find out.

Connect Twitch, clips ready after the stream: Planned, through the official Twitch clip API. Not built. Today you upload a file.
An OBS script: Planned: it would send your audio when OBS stops recording. Not built.
Posting for you: Not available, and not promised. You download MP4 files and post them yourself.
A scene change inside one clip: Not handled yet. A clip that crosses two scenes can show the wrong layout.

Where your files go

Your recording is the only thing we keep, and not for long.

Your source video is deleted 3 days after you upload it.
Your clips are deleted 30 days after we make them. Download what you want to keep.
