Supported captions workflows, input captions in the same file as video

To look up whether MediaConvert supports your captions workflow, choose the topic from the following list that corresponds to your video output container. Then find the row that corresponds to your input captions container and format. Check the supported output captions format column to see the available output captions formats.

Supported captions in CMAF output container

The following table lists supported output captions formats for this output container, when your input captions are in the same container or stream as your video. This table is sorted by the input captions container and input captions format.

If your input captions are in a sidecar format, see Sidecar captions supported in CMAF output container. Sidecar captions are captions that you provide as a separate input file from your video.

Sidecar captions supported with File output groups

The following table lists standalone sidecar output captions formats that MediaConvert supports with outputs in the File output group. Sidecar captions are captions that are in a separate file from your video.

If your input captions are in a sidecar format, see Sidecar captions supported with File output groups. Sidecar captions are captions that you provide as a separate input file from your video.

When you set up these output captions in your job, choose No container (RAW) for Container, under Output settings. In your JSON job specification, specify it this way:

{ "ContainerSettings": { "Container": "RAW" },
Note

You can create sidecar captions outputs only as part of a job that also generates a video output.
