Neat PR, what's the cost overhead of this? |

Hopefully it won't be much work, but the callbacks are being refactored in parallel, |

Do you have an example of the gif as saved in mlflow? |
Have a look at this one: https://mlflow.ecmwf.int/#/experiments/23/runs/6172b5513408422f967895ecbe6101c2/artifacts |

Create a video of a forecast of several variables starting from a validation sample.
This functionality builds up on the LongRolloutPlot function, which saves snapshots after longer rollouts.
The number of rollout steps can be higher than the number of rollout steps used for training.
To allow longer rollouts in validation, the validation batches are made longer. This has no effect on the actual batch size.
The runtime to do the rollout is low, but creating multiple scatter plots and saving them to a gif takes around a minute per variable for a 14-day rollout of 6-hourly forecasts.
Therefore, by default, the video rollout is not enabled.
If enabled, the default is to do a 56-step forecast video every 20 epochs.
