Setting Up AV-Sync
This guide walks you through the complete process of setting up AV-Sync to synchronize audio with video displays in your exhibit.
Step 1 — Process your video files
Section titled “Step 1 — Process your video files”- Download the AV-Sync Tool
- Load your original video file into the tool
- The tool generates two outputs:
- A video file with an embedded timecode track
- A separate audio file for the Guide-ID platform
Once your files are ready, create an AV-Sync stop in the Tour Editor. Click Add Stop and select Audiovisual Sync Tour Stop as the stop type. The dialog also provides a download link for the AV-Sync video tool.

After creating the stop, it appears in the stop list with a video camera icon to distinguish it from regular audio stops.

Step 2 — Assign a video code
Section titled “Step 2 — Assign a video code”Each video requires a unique identifier starting with A1 (for example, A101 or A102). Enter this code in the Video Code field of the AV-Sync stop.

If the code does not follow the correct format, a validation error is displayed. The code must start with A1, followed by exactly two characters (for example, A101).

Step 3 — Configure the platform
Section titled “Step 3 — Configure the platform”- Upload the audio file to a dedicated AV-Sync stop in the Guide-ID platform
- Pair the stop with the corresponding video code
- Assign the correct beacon identifier to the stop
When a beacon is assigned and the video code is valid, a green checkmark confirms the configuration is correct.
