INAV Black Box Log Viewer
I. INAV Blackbox Explorer
This tool allows you to open logs recorded by INAV's Blackbox feature in a web browser. You can use it to check graphical values for each time step. If you have flight video, you can also load it to play after the log. You can export charts as WebM videos to share with others.

Synchronizing Logs with Flight Videos
The blackbox system emits a short beep through the buzzer when the aircraft is armed, which marks the official start of data recording. To precisely synchronize the flight log with the video, you can click the "Start Recording From Here" button when you hear the beep in the video for automatic alignment.
For further fine-tuning of the synchronization position, you can manually adjust using the "Left/Right Shift" buttons in the log synchronization area, or directly enter a specific value in the "Log Synchronization" input box—entering a positive value will shift the log data toward the end of the video, while a negative value will shift it toward the beginning.
This design preserves the convenience of using the beep as a clear synchronization reference while providing professional-level fine-tuning control, supporting frame-precision audio-video synchronization through numerical input.
