Properly configuring your BlackVue dashcam's recording loop and event duration ensures you capture key footage efficiently and manage memory card space wisely. This guide explains how recording segment length and event file durations work, and provides tips for optimal use.

Understanding loop recording and event duration

• Loop recording:
  Video is saved in segments (e.g., every 1 minute). When the SD card is full, the oldest unprotected files are overwritten so your dashcam always has the most recent footage.
• Event file duration:
  Special event files (triggered by impact, motion, or manual input) are typically of a fixed length—long enough to cover both the incident and surrounding context.

Setting loop recording segment length

• Most BlackVue dashcams save video in fixed-length segments. Many recent models use 1-minute video segments by default, which cannot be changed in the menu (especially in DR770X, DR900X, DR970X, X/LTE series).
• On some older or specific models, segment length may be adjustable between 1, 2, 3, 5, or 10 minutes. Check your model’s manual or settings page.
• File sizes: Longer segments mean fewer files but larger file sizes; shorter segments are quicker to access and upload, and minimize data loss if a file is corrupted.

Event file duration and settings

• Event file duration is generally set by BlackVue firmware and is not user-adjustable.
  • Standard duration: Often 1 minute, recorded with pre-event buffer (several seconds before trigger) and post-event footage to capture the full incident.
  • Event files are automatically protected from overwriting unless the card is completely full and “overwrite locked files” is enabled.
• Manual event recordings: The process is identical—manual triggers make 1-minute clips, starting several seconds before the button (using buffered recording).

How to set (or view) your segment and event durations

1. Open the BlackVue app or Viewer.
2. Connect to your camera via Wi-Fi or Cloud.
3. Go to Camera Settings > Recording Settings.
   • You’ll see segment length (may be “fixed at 1 minute” for most models).
   • You can adjust event trigger sensitivities (G-sensor, motion detection) in the same menu.
4. Save settings and restart the dashcam for any changes to take effect.
   • Note: Some segment/event durations can only be changed via configuration on older models or the BlackVue Viewer PC software.

Important tips

• Backup before changing time or image quality settings!
  On some models, altering video length or quality will require SD card formatting and will erase existing footage.
• Event files are protected unless memory is full or settings allow overwriting locked files.
• Manuals and firmware updates: Always check for model-specific details in your dashcam’s official manual and update firmware for the latest options.
