# Are there limits for upload time or processing time? Assemblies must complete uploads within 8 hours and processing within an additional 8 hours. For example, a 10-minute upload gives your Assembly 8 hours and 10 minutes to finish transcoding. If uploading exceeds 8 hours, the Assembly expires, capping at a 16-hour limit from creation for both uploading and processing combined. Assemblies will return the `ASSEMBLY_EXPIRED` error when they expire. ## See also: [Why doesn’t Transloadit charge by the minute?](/docs/faq/charge-by-minute.md) [How are my Amazon S3 credentials protected?](/docs/faq/s3-safe.md) [Can you help me understand the pricing?](/docs/faq/pricing-example.md)
