The match is slow or stalls

What drives match time, what to do when a match hangs, and how to file a useful bug report.

Since July 2026 the beta has matched 19,156 clips at a median of 1.2 seconds per clip. If your runs sit well outside that, this page is the checklist.

What drives match time

Three factors, in roughly descending order:

• How many clips are selected. MOVON reads color from every selected clip, so 60 clips take longer than 6. Linear, not worse.
• Connection quality. The match runs on MOVON's servers, so the numbers have to get there and the grades have to come back. The payload is small, but a flaky or high-latency connection stretches the round trip.
• Reading the timeline. The local step is the panel reading color out of Premiere. A background render slows that read. Quitting the heavy stuff usually shaves time off the next run.

What does not matter much: clip length, codec, resolution. MOVON samples color from a few frames, not the whole clip.

When a match hangs

The progress bar moves, then stops

Almost always one of two things:

• A clip is offline or unreadable. Premiere shows it as Media Pending; MOVON cannot sample it. Re-link the media, then match again.
• A proxy that was rendered to a different color space while the original sits in LOG. Turn proxies off for the pass (Premiere → Preferences → Media), then turn them back on.

The progress bar never starts

The panel cannot reach MOVON's servers.

• Check the connection dot in the panel. Grey or red means no connection.
• Confirm the Mac is online and the panel is signed in.
• A firewall or VPN can block the outbound connection. Allow MOVON, or pause the VPN for the pass.

Plugin won't load has the longer connection walk-through.

File a useful bug report

If the match is slow in a way nothing above explains, the homepage Contact form reaches MOVON Labs directly. A useful report has:

• Mac model and chip (M1 Pro, M2 Max, Intel i9). Apple menu → About This Mac.
• macOS version.
• Premiere version.
• Clip count in the selection. Rough is fine.
• Time taken, with a stopwatch from the click to the result appearing.

That is enough to tell whether the run sits on the normal curve or outside it.
