Analysis is slow or stalls

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

Honest first: MOVON Match is in private beta and the inference path is still being tuned. The target is a full multicam timeline matched in about a minute. That is a target, not a measured benchmark. Real numbers go on this page once they are measured.

In the meantime, this is what affects match time today and what to do if Analyze hangs.

What drives match time

Three factors, in roughly descending order:

• Number of clips in the selection. MOVON reads color data from every selected clip, so a 60-clip selection takes longer than a 6-clip one. Linear, not quadratic.
• Connection quality. The match is computed on MOVON's servers, so the color data has to get there and the LUTs have to come back. The payload is small (color data, never footage), but a flaky or high-latency connection stretches the round trip.
• Reading the timeline. The local step is the plugin reading color data out of Premiere. A render in the background or other heavy work in Premiere slows that read; quitting non-essentials usually shaves time off the next Analyze.

What does not drive match time meaningfully: clip length, codec, resolution. MOVON only samples color data from a few frames, not the full clip.

When Analyze hangs

Two cases.

Progress bar moves, then stops

Almost always one of two things:

• A clip on the timeline is offline or unreadable. Premiere shows it as Media Pending; MOVON cannot sample frames from it. Open the project panel, re-link the offline media, then re-run Analyze.
• A clip is in a proxy that was rendered to Rec.709 while the original sits in LOG. Proxies that flatten the color space confuse the match. Toggle off proxies for the Analyze pass (Premiere → preferences → Media → Enable proxies off), then re-enable after.

Progress bar never starts

The panel cannot reach MOVON's servers.

• Check the connection dot in the panel; grey or red means no connection to MOVON.
• Confirm the Mac is online and the panel is signed in to your MOVON account.
• A firewall or VPN can block the panel's outbound connection. Whitelist MOVON, or pause the VPN for the Analyze pass.

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

File a useful bug report

If the match is slow in a way that does not match anything above, the homepage Contact form reaches MOVON Labs directly. A useful report has:

• Mac model and chip (M1 Pro, M2 Max, Intel i9, etc.). Apple menu → About This Mac copies the line.
• macOS version.
• Premiere version.
• Clip count on the timeline (rough is fine).
• Time to Analyze in seconds or minutes, with a stopwatch from the click to the plan landing.

That is enough for the team to know whether the run is matching the performance curve or sitting outside it.

What is in the pipeline

Inference-performance tuning is in active development for the private beta. The two pieces moving the needle on the server side: smaller model variants for short selections, and parallel sampling so multiple clips process at once. The dispatch on the homepage carries each cut as it lands.
