Multicam auto-cut tool · macOS

Audio drives the cut.You keep the creative part.

RIM CHOP analyses the audio, syncs your festival cameras and places each cut on the drop. You get a fully switchable multicam edit directly in your open Resolve or Premiere project.

Works with the NLE you already have open. Source media in, editable multicam project back — processed locally on your Mac.

Save your night for the edit, not the sync. Festivals·Clubs·Artists
Three simple steps

From footage to finished reel.

Load the cameras, let RIM CHOP find the drops, open a switchable multicam edit in your NLE. The whole way through, nothing is flattened.

01

Pull straight from your open project.

Drop in every camera and a reference track — or let RIM CHOP read the project you already have open. It sees your sequences, your media pool, your timecode, and takes it from there.

Wrong camera? One key.

RIM CHOP puts the edit back into the app you left open, and every cut still knows all your cameras. If the third drop sits on the wrong angle, you press one key instead of rebuilding the clip — your trims, zoom and shake stay where they are.

Built for the drop

Not a sync tool. An edit.

Everything RIM CHOP builds stays editable — real multicam clips, real angles, ready to finish.

Switchable multicam

Angle per cut as a real multicam clip. Re-pick any shot — ⌥ + a number in Resolve, number keys 1–9 in Premiere — no cut slips.

Writes a real .prproj

A finished Premiere project with a pre-picked angle per cut — no plugin required. The app runs on macOS; the project opens in Premiere on any OS.

Camera RAW sync

Compatible with Blackmagic Design Blackmagic RAW — plus other professional camera RAW through the manufacturer SDKs — footage ffmpeg can't open.

Drop-driven cuts

Beat and energy detection place a hard cut on the drop with weighted camera roles.

Local captions

On-device Whisper captions with animated styles. No clips uploaded anywhere.

Auto-reframe

Five formats — 16:9 · 9:16 · 4:5 · 1:1 · 5:4 — grade-preserving.

RIM CHOP delivers to

Straight into your NLE.

Not a file hand-off. RIM CHOP talks to Resolve and Premiere while they are open — it reads your running project and the finished edit lands in the app you already have in front of you. The whole conversation stays on your machine.

Built by a festival videographer

A tool for me. A tool for you.

RIM CHOP grew out of real full-night festival shoots. Syncing a wall of cameras and razoring every reel by hand ate entire nights; existing tools either missed professional RAW or stopped before the actual edit. RIM CHOP handles that routine and returns a switchable multicam project in Resolve or Premiere — so the machine does the repetitive work and you keep the creative decisions.

Questions

Good to know.

Do I need DaVinci Resolve Studio?
RIM CHOP delivers into DaVinci Resolve and Adobe Premiere Pro. For Resolve it can drive Resolve Studio directly, or hand off an FCPXML you import into any Resolve. For Premiere it writes a ready-to-open project — no plugin needed.
What sync methods are supported?
Embedded timecode and LTC for jam-synced rigs, plus audio-fingerprint sync when there's no shared timecode. RIM CHOP also reads Blackmagic RAW and other professional camera RAW through the manufacturer SDKs, so RAW that ffmpeg can't open still syncs cleanly.
Can I still edit after RIM CHOP builds the reel?
Yes — that's the point. You get a real, switchable multicam timeline. Re-pick any angle (⌥ + a number in Resolve, number keys 1–9 in Premiere), trim, grade and finish exactly like a project you cut yourself. Nothing is flattened.
What does it output?
FCPXML 1.9 for Resolve, FCP7 XMEML for Premiere's XML import, and a direct .prproj with multicam and a pre-selected angle per cut. Reels reframe to five formats — 16:9, 9:16, 4:5, 1:1 and 5:4.
Which platform?
RIM CHOP runs on macOS. Captions and analysis run locally on your machine — nothing is uploaded.
