Video - Trainy Konduktor

Logging

You can log video in the following formats:

MP4 - MPEG-4 Part 14 container format
GIF - Graphics Interchange Format
WebM - Open web media format
M4A - MPEG-4 Audio format
OGG - Free, open container format

To log a video, instantiate the pluto.Video class:

video = pluto.Video(
    data: Union[str, np.ndarray],
    rate: int | None = 30,
    caption: str | None = None,
    format: str | None = None,
)
pluto.log({"video/file/0-0": video}, step=step)

Parameter	Type	Description
`data`	`Union[str, np.ndarray]`	The video data to log. Can be a path to a video file or a NumPy array.
`rate`	`int`	The frame rate of the video. Defaults to 30.
`caption`	`str`	A caption for the video.
`format`	`str`	The format of the video. Defaults to `mp4`.

Examples

Logging Videos from File Paths

path = "video.mp4"
pluto.log({"video": pluto.Video(path)}, step=step)

Logging Videos from NumPy Arrays

data = np.random.randint(low=0, high=256, size=(10, 3, 112, 112), dtype=np.uint8)
pluto.log({"video": pluto.Video(data)}, step=step)

Viewing

Logged videos appear as playable widgets. Each video card includes standard playback controls (play/pause, seek) and displays the filename and associated run.

When comparing multiple runs, video widgets from each run are shown together, making it easy to visually compare generated outputs or training episodes across experiments. If you log videos at multiple training steps, use the step slider below the players to browse through different steps. When multiple video groups are displayed in the same section, their step sliders can be linked so that changing the step on one group changes all of them simultaneously. Click the lock icon on the step navigator to toggle sync on or off.

Multi-Sample Logging

If you log a list of videos at the same step under one log name (e.g. pluto.log({"rollouts": [pluto.Video(a), pluto.Video(b)]}, step=10)), every video renders inside the same card with a per-cell ◀ i / N ▶ nav row above the player. The same nav row appears next to the filename in the fullscreen video viewer, and the inline and fullscreen states stay in sync.

Fullscreen View

Click the expand button on any video card’s toolbar to open it in fullscreen. The fullscreen view displays the full multi-run comparison at viewport size. Use arrow keys to navigate between steps.
