Churchable: shipping an AI-powered video shorts feature inside an existing product

I joined Churchable as a specialist contractor to build a workflow that turns long-form sermon videos into AI-suggested short-form clips. The work combined an existing Next.js/React product with Remotion, transcript timestamps, Supabase, Deepgram and large-video processing.

Clip editor: Remotion inside the existing Next.js appFIG. 1

(01)Context

Churchable helps churches extend the reach of their services. The founder wanted to turn long-form sermon recordings into short clips ready for social media, inside the product they already had.

(02)Role & scope

→Scoping the feature directly with the founder
→AI clip-suggestion workflow
→Remotion editor integration in the existing Next.js/React app
→Large-video handling, rendering and media optimization

(03)Constraints

C1An existing codebase and conventions to work within, not around.
C2Long, large source videos.
C3A tight timeline for the initial version.

(04)Approach & key decisions

1.

Transcript-driven clip selection

Clips are suggested from the transcript and its timestamps, using Deepgram, and stored alongside existing data in Supabase.

2.

Remotion inside the existing app

Instead of a separate tool, the editor was integrated into the current Next.js/React product so users never leave Churchable.

3.

Optimize media early

Large-video handling and rendering were treated as first-class concerns from the start, not a later fix.

(05)What was built

+Sermon-to-shorts AI workflow
+Timestamp-based clip suggestions
+Embedded Remotion clip editor
+Rendering and media pipeline for large videos
