VAST-3.0-minmaxbitrate-pair
<MediaFile> must have both minBitrate and maxBitrate or neither
ErrorValuesIAB VAST 3.0 §2.4.1VAST 3.0, 4.0, 4.1, 4.2, and 4.3
Short answer
minBitrate and maxBitrate must be used together. Specifying one without the other leaves the range undefined.
Why this matters in production
This rule is usually a delivery blocker. Many players, SDKs, and ad servers will discard the response or skip the affected creative once this condition is hit. Value-format rules tend to fail at the moment a player interprets a field such as duration, skipoffset, bitrate, or versioning. They are especially painful because the XML can look valid at a glance. Affected scope: VAST 3.0, 4.0, 4.1, 4.2, and 4.3.
How to fix
Either provide both minBitrate and maxBitrate, or use the single bitrate attribute — not a mix of the two.
