AWS Elemental MediaConvert fails to transcode some iOS videos that were transferred to MacBook

David, thank you for your question. Can you provide additional details about the transcode workflow?

• Are the MediaConvert jobs being created automatically, via a lambda function or some other code?
• Is the MediaConvert in the same account as the S3 buckets providing the source files?

A few observations:

• The source file has an http:// reference, which indicates the source could come from beyond the AWS account where MediaConvert resides. Cross account accessing of files would require IAM roles that allow that. If the S3 bucket and MediaConvert are in the same account, you may want to consider using the format s3://<bucket_name>/<path>/<source_file_name>, where <bucket_name> does not include 's3.amazonaws.com'.
• Can you indicate why the parameter 'REMOVED=true' is in source file path name? You may want to try removing that and seeing if the results are better.
• MediaConvert should be able to handle both .mp4 and .mov source file formats. If the errors are only indicating 'not found', getting beyond that may allow both to be ingested.

Hello David,

I looked through the MediaConvert Documentation and found a "Note" that is on topic:

"Note: MediaConvert doesn't support external reference MOV, external reference MXF, or fragmented MP4 initialization segments. Your MOV, MXF, or MP4 inputs must be self-contained."

It might be the case that you are getting the "not found" error because MediaConvert does not detect the media files within your MOV file. Try and check to ensure that your MOV file has all of the necessary video components within the file, and is not referring to external files. It needs to be a standalone file - meaning that everything needed to play back that file is contained within the file itself.

Here is a Complete list of MediaConvert compatible inputs.

I hope this helps, and please do not hesitate to contact us if you need to continue the conversation.
