Shot-Detection Troubleshooting for Match Video
Review the waveform and detected events when automatic gain control (AGC), neighboring shots, echo or reverb, or a weak timer beep changes the recording.
Updated: 2026-07-29
Detection is an editing aid. The shooter or editor remains responsible for verifying the timer marker, event timeline, trim boundaries, subtitles, and finished video before export.
Fix the reference point before individual events
- Confirm the timer beep. Play the start region, locate the real timer beep in the waveform, and correct the timer marker when needed.
- Inspect the start and end region. Check the footage around the beep, first shot, last shot, and trim padding before changing individual events.
- Review neighboring and echoed events. Compare suspicious markers with the audio and picture to separate the shooter’s events from neighboring shots, echo, or reverb.
- Add, remove, or correct events. Add a missed shot, remove an extra event, set the correct last shot, or adjust sensitivity and minimum split.
- Preview subtitles and trim. Watch the edited run with its selected timing subtitles and confirm the start, finish, event order, and total context.
- Export the verified edit. Export only after the waveform, detected events, trim boundaries, and visible result agree with the intended run.
Match the recording symptom to the next review
| Condition | What may change | Review next |
|---|---|---|
| Weak timer beep | The proposed start marker may not match the real beep | Start waveform, timer marker, and pre-roll padding |
| Automatic gain control | Relative event loudness can change during the clip | Sensitivity, missed events, and extra events |
| Neighboring gunshots | Another shooter’s events can resemble events in the edited run | Audio, picture, event order, and minimum split |
| Echo or reverb | One shot can create additional waveform peaks | Duplicate markers, spacing, and the last-shot choice |
Use the timeline controls before export
Move the timer marker when the real beep is visible elsewhere in the waveform. Add a missed shot or remove an extra event after comparing the marker with both audio and picture. Set the correct last shot so the timing and end trim refer to the intended final event.
Detection sensitivity and minimum split can help when the recording makes real events too weak or places peaks too close together. Change one assumption at a time, then preview the subtitles and trim again.
For one stage recording, return to the Auto Trim workflow. For two audio-aligned views, review the same evidence in Split Sync.
The detection-improvement option is user controlled
The inline editor labels this option “Improve Detection” or “Improve,” while export settings use “Help Improve Gunshot Detection.” It is currently enabled by default and can be turned off.
When enabled, the option can send limited pseudonymous derived detection fields, random session or analysis identifiers, and correction events to Apple CloudKit. Reports exclude original video, original audio, and PCM audio. While disabled, Shooting Cut creates no new reports and does not retry the local pending queue; disabling does not erase reports already submitted or clear that local queue.
Read the Privacy Policy for the complete field, retry, retention, and control boundaries.
Frequently asked questions
What should I check first when the trim starts at the wrong time?
Play the start region, find the real timer beep in the waveform, and correct the timer marker before changing individual shot events.
Why can extra shot markers appear?
Automatic gain control, neighboring gunshots, echo, or reverb can change the recorded waveform. Compare each suspicious marker with the audio and picture before removing it.
Can I correct missed or extra events manually?
Yes. You can add a missed shot, remove an extra event, move the timer marker, set the correct last shot, and adjust sensitivity or minimum split.
What does the detection-improvement option send?
When the user-controlled option is enabled, it can send limited pseudonymous derived detection fields and correction events to Apple CloudKit. It excludes original video, original audio, and PCM audio.
