# Topaz Dione DV

VIDEOFeaturedtopaz-dione-dv-upscale-video

Dione DV is the deinterlacing tier of Topaz Labs’ precision video upscaler, resolving the combing artefacts in interlaced DV and legacy tape sources while enlarging up to 4x. Best for archive footage that no other upscaler will clean up correctly.

## Parameters

### Path Parameters

**workspace\_id**

required

_Workspace Id_

Id of the workspace that owns the resource.

string format: uuid

Id of the workspace that owns the resource.

### Query Parameters

**session\_name**

_Session Name_

Organize this run under a named session. A new session is created if none matches.

string

nullable

Organize this run under a named session. A new session is created if none matches.

### Header Parameters

**Idempotency-Key**

string

<= 255 characters

Opaque key making a retry of this request return the first result. A 2xx response is replayed for 24 hours with `Idempotent-Replayed: true`. A 4xx releases the key. A 5xx, or a request still running, holds the key for 120 seconds, during which a retry gets 409; after that a retry executes again. The key covers the method, path, query, and byte-identical body it was first used with; reusing it for a different request is rejected with 422\. Protection is best effort: if the key store is unavailable, or a record is lost early, a retry can execute again even after an earlier 409\. See the Idempotency section of the API description.

## Request Bodyrequired
