This topic provides details on the Zencoder API error: ChecksumMismatchError.


The MD5 checksum computed for the input file does not match the checksum supplied to the API.

There are a variety of possible causes for this problem. The most likely are:

  • The file was corrupted in transit.
  • The checksum supplied to the API was incorrect.


Check to make sure that the checksum you supplied to the API matches the checksum of the file on disk.

If they don't match, please make a new API call with the proper checksum.

If the checksums do match, the file may have been corrupted during transfer. Please resubmit the job.

In either case, if the retry fails, please contact us.
