<pre>
The picture field parity assumed for the input interlaced video.
The default is `auto`.
Supported values:

- `tff`: Assume the top field is first
- `bff`: Assume the bottom field is first
- `auto`: Enable automatic detection of field parity

<code>string parity = 2;</code>

@return The bytes for parity.
