# List Translation Export Files

> List the downloadable files of a translation with temporary download links

This endpoint returns the downloadable files of a single target language (final video, mixed
audio, synthesis-only audio, adapted script, subtitles, cast), each with a temporary presigned
download link.

Only files that are currently available are returned. Files that are still being produced are
omitted, so you can poll this endpoint until the file you need appears in the response.

## Path Parameters

<ParamField path="projectId" type="string" required>
  The unique identifier of the project.
</ParamField>

<ParamField path="videoId" type="string" required>
  The unique identifier of the video.
</ParamField>

<ParamField path="locale" type="string" required>
  The target language code, matching one of the video's `dstLangs` (e.g. `en-GB`). Case-insensitive.
</ParamField>

## Response

The response is a JSON array of file objects. Each object has the following fields:

<ResponseField name="presignedUrl" type="string">
  Temporary presigned URL to download the file directly from storage. Valid for 24 hours (see `expiresAt`).
</ResponseField>

<ResponseField name="filename" type="string">
  Name of the file, including its extension (e.g. `tts_final.mp4`, `subs_hitl.vtt`).
</ResponseField>

<ResponseField name="modifiedAt" type="string">
  ISO timestamp of when the file was last modified.
</ResponseField>

<ResponseField name="expiresAt" type="string">
  ISO timestamp of when `presignedUrl` expires.
</ResponseField>

<Note>
  The synthesis-only audio `tts.wav` may be a single multichannel file with one channel per
  speaker. Channels are ordered by speaker id sorted as strings (e.g. `F0`, `M0`, `M1`). To map a
  channel to a speaker, collect the distinct speaker ids from the adapted script (`tts_hitl.vtt` /
  `tts_auto.vtt`) and sort them the same way — the channel index is the speaker's position in that
  sorted list.
