Troubleshooting
Analysis Taking Too Long
Problem: Immediate analysis hasn't returned results
Solution: Check your internet connection. Analysis requires uploading video to the cloud. Try again with a shorter video clip using the interactive timeline.
Low Analysis Quality
Problem: Scores or action detection seem inaccurate
Solution: Ensure good lighting and a stable side-angle recording. Avoid recording from behind the fencers.
