Can I merge subtitles with MP4 in AWS transcribe?

0

I created a transcription JSON file (not sure what I can do with it; but I am still learning) and SRT subtitles for MP4 file in S3 bucket. Now, I obviously want to merge the two, so I can show the video with subtitles. Can I do it inside Amazon Transcribe? I know there are third-party tools to do that; but I would prefer to have a single workflow to do everything. I couldn't find anything in the docs - just a very short section on how to generate subtitles.

UPDATE: I tried to create a job in AWS Elemental MediaConvert, and got the following error: Media target 1 cannot convert non-EIA-608 to EIA-608 (invalid conversion from SRT to Embedded attempted)

Hi,

You cannot do it directly from Transcribe, you would need to use AWS Elemental MediaConvert (Caption Selector, external file) to do that : https://docs.aws.amazon.com/mediaconvert/latest/ug/set-up-captions-in-outputs.html

Please refer to this document for a list of supported caption workflows for sidecar captions support : https://docs.aws.amazon.com/mediaconvert/latest/ug/sidecar-captions-support-tables-by-container-type.html. You can see that the supported caption output formats are all text-based (IMSC, WebVTT, TTML for example), not embedded like EIA-608.

You can automate this workflow using EventBridge to trigger the MediaConvert job as soon as the Transcribe job is finished : https://aws.amazon.com/eventbridge/features/
