Media Quality Requirements

If your media meets the listed requirements, this ensures the highest analysis accuracy. If media does not meet the minimal requirements, accuracy is not guaranteed.

We highly recommend using our SDK to capture media. This ensures your media meets all requirements, and you receive the most reliable analysis results.
