Problem[01]
Which toast had that line
The father of the bride told a story about her at six that the couple will want in the film. It is somewhere in forty minutes of toasts, on one of two cameras.
For Wedding and event filmmakers
Every vow and toast, found without a watch-through
Two shooters, a drone, a ceremony, five toasts and a dance floor: indexed on your Mac before you open Resolve. Ask for the line the maid of honor got a laugh on 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 Wedding and event filmmakers down
Problem[02]
A night of sorting cards
Getting ready, first look, ceremony, portraits, reception. Putting the cards from every shooter into the order of the day eats the first evening of every edit.
Problem[03]
Ten films deep by August
Peak season stacks up weddings faster than you can deliver them. Each highlight film starts with a full watch-through, and couples are counting the weeks.
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 |
|---|---|---|
| Vows and toasts, transcribed | On your Mac | Whisper on the Mac's GPU writes every word with its time, so you can search the toasts for a name, a story or a phrase. |
| Speakers told apart | On your Mac | Up to four voices within each clip, and the same voice recognized across clips. Name the officiant, the couple and the readers once, and every clip knows them. |
| The day in order | On your Mac | Clips from every camera grouped into scenes by their capture times, so getting ready, the ceremony and the reception line up across shooters. |
| Laughs and loud moments | On your Mac | Moments that rise above the room are marked with their times: where the laugh, the cheer or the applause after the kiss is likely to be. |
| Dark, blown or soft clips flagged | On your Mac | Underexposed reception footage, blown-out window light and missed focus flagged per clip, plus the steadiest stretch of each shot. |
| Moments to cut on | Claude or OpenAI | Entrances, reveals and reactions with in and out points and a usability score, like the walk down the aisle. With your own Claude or OpenAI API key. |

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 the part of the best man's speech where the whole room laughs.
The speech transcribed, with the moments that rise above the room marked and timed, so you play only those.
Your AI app02
Where do they say “I do”?
Each clip where the words are spoken, from both cameras, with the line and the timecode to cut on.
Your AI app03
Build a four-minute highlight film from the ceremony and toasts.
A timeline in DaVinci Resolve Studio with the vows, the best toast lines and the strongest moments between them.
Your AI appIs the couple's footage uploaded anywhere?
No. Indexing, transcripts and speakers run on your Mac, and no video or audio leaves it. Only if you turn descriptions on does Prewatch send still keyframes and transcript text to Claude or OpenAI with your own key, at a cost shown up front.
What about toasts in another language?
Whisper detects the language once per clip and transcribes in it, so a toast that switches language midway is transcribed in the one heard most. An English translation comes alongside: from the description model with your key, or a rougher one from Whisper on the Mac.
Do I need to sync my cameras first?
Prewatch doesn't sync cameras or audio. It indexes each clip on its own and puts the day in order by each file's capture time, so set every camera's clock to match before the wedding.
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.
