+### Manifest Size Considerations
+
+For larger payloads, the number of entries in the `integrityInformation.segments` array directly determines the manifest size. As segment count increases, the `integrityInformation` length grows proportionally. With the default settings, a 1 TB TDF file with 1 MB segments will result in approximately one million segment entries in the manifest. Some SDKs impose maximum length limits on the manifest. To avoid problems with very large payloads, either configure your client to allow larger manifest sizes or to encrypt with larger segment lengths.
