Decoded frames with the alignment data a video model reads beside them: frames, a host uint8 Tensor of shape [K, H, W, 3] (channels-last RGB; move it with .to()), indices, the source frame index of each row, pts_seconds, each frame's presentation time on the clip's own timeline (offsets and uneven spacing included), and duration_seconds, each frame's display duration. len() is K; batch[k] is a one-frame FrameBatch whose frames is a view of row k (no pixel copied), so the batch iterates frame by frame.

## `duration_seconds` (property)

Each frame's display duration in seconds.

## `frames` (property)

The packed frames, a host uint8 Tensor of shape [K, H, W, 3].

## `indices` (property)

The source frame index of each row, in order.

## `pts_seconds` (property)

Each frame's presentation time in seconds, the container's own timeline.

## `__init__`

```python
__init__(self, /, *args, **kwargs)
```

Initialize self.  See help(type(self)) for accurate signature.
