Problem[01]
Which try was the make
You tried it fifteen times. The make is GX010043 or GX010071, and in a thumbnail every attempt is the same blur of sky and concrete.
For Action sports filmmakers
The make, found without watching twenty bails
Helmet cam, chest mount and a friend filming from the bottom of the stairs: a day of runs and attempts, indexed on your Mac. Ask for the try everyone yelled about and get the clip and the seconds.
14 days free, then $59 a year or $7.99 a month. Works with your Claude or ChatGPT plan; timelines need DaVinci Resolve Studio 21.1+. Clip descriptions are optional and use your own API key, billed by Anthropic or OpenAI.

Problems
What slows Action sports filmmakers down
Problem[02]
Eight hours of POV
The helmet cam ran from the first chair to the last lap, no notes. The two good runs sit somewhere between lift rides and pushing back up the hill.
Problem[03]
The season edit slips again
Every weekend adds a card from the park, the trail or the break. By the end of the season there's too much to watch, and the edit moves to next year.
What Prewatch gives you
Your footage, already watched
Prewatch indexes every clip on your Mac, so Claude or ChatGPT knows what is in your footage and can build the cut with you in DaVinci Resolve Studio.
| What you get | Where it runs | What it does for you |
|---|---|---|
| Tries and reactions | Claude or OpenAI | Action, reactions and the last attempt, read from keyframes and from what's said (“last one”, the yelling after), with in and out points. With your own Claude or OpenAI API key. |
| Shake that's normal for POV | On your Mac | Every shot classed steady, handheld or shaky from the picture. Moments aren't scored down for shake when most of that camera's footage is shaky. |
| GoPro settings from the file | On your Mac | Model, Protune, color profile, field of view, stabilization, white balance and ISO limits, read from HERO5 and later files. Protune Flat clips are marked flat. |
| Shouts and crashes, heard | On your Mac | Moments where the sound jumps above the clip's own level are marked and timed, and the Mac app tells a voice apart from wind on the mic. |
| Steadiest seconds per clip | On your Mac | The five steadiest stretches of every clip, ranked from the picture, so a rough run still gives you its clean seconds. |
| Sessions by day and spot | On your Mac | Clips grouped into days and scenes by capture time and, when the camera recorded it, location, so each session reads as one. |

Ask it
One question instead of a day of scrubbing
You ask in Claude or ChatGPT. Prewatch answers with the clips, the seconds and the timecode, and your assistant builds the timeline in DaVinci Resolve Studio.
01
Find every try of the kickflip down the eight stair.
Clips where the attempt was seen or talked about, with the reactions after and in and out points, highest usability first.
Your AI app02
Which of Saturday's laps are too shaky to use?
The shots classed shaky, each with its steadiest seconds, so you see what can still be saved.
Your AI app03
Cut a two-minute season edit, one beat per session.
A timeline in DaVinci Resolve Studio built from the top-scored action, in the order the sessions happened.
Your AI appWill it mark all my POV footage as shaky?
A shot is classed shaky when it is. But moments aren't scored down for shake when most of that camera's footage in the folder is shaky, as with a helmet or chest cam, so the best action still rises to the top.
Does it read GoPro metadata?
Yes, from the HERO5 on: model, firmware, Protune, color profile, field of view, stabilization, white balance, sharpness and ISO limits come from the file itself. Older GoPros give their firmware only. The gyro and GPS telemetry track isn't read, so shake is measured from the picture.
Can it tell a make from a bail?
Not reliably on its own. The description model reads still keyframes and the transcript, so it finds the attempts and the reactions after them, and what people say (“he landed it”, “so close”) helps most. Watch the last seconds of each try yourself before you cut.
Does it work with the free version of DaVinci Resolve?
Building timelines by chat needs DaVinci Resolve Studio 21.1 or later, whose built-in MCP server lets your assistant work in Resolve. With the free version you can still index your footage, search it and ask Claude or ChatGPT about it, then place the clips yourself. A file handoff that the free version can import is planned.
How does the free trial work?
Prewatch is an App Store subscription with a 14-day free trial: $59 a year or $7.99 a month after it. You manage or cancel it in your Apple Account's subscription settings; cancel before the trial ends and you are not charged.
Try it on your own footage
Point Prewatch at a folder you have already shot, then ask about it in Claude or ChatGPT.
