+# 1.2.8 Media Alternative (Prerecorded)
+
+- Level: AAA
+- Guideline: 1.2 Time-based Media
+- Principle: 1 Perceivable
+
+## What it is
+
+An alternative for time-based media is provided for all prerecorded synchronized media and for all prerecorded video-only media.
+
+## How to test
+
+- Check: An alternative for time-based media is provided for all prerecorded synchronized media and for all prerecorded video-only media.
+- Use the sufficient techniques below as acceptable methods when applicable.
+- Confirm none of the common failures apply.
+
+## Sufficient techniques (W3C)
+
+- G69: Providing an alternative for time based media
+- G58: Placing a link to the alternative for time-based media immediately next to the non-text content
+- H53: Using the body of the object element
+- G159: Providing an alternative for time-based media for video-only content
+
+## Common failures (W3C)
+
+- F74: Failure of Success Criterion 1.2.2 and 1.2.8 due to not labeling a synchronized media alternative to text as an alternative
