FAQ¶

Which file types can I add as inputs?¶

The Add Data picker supports common video/image extensions (.mp4, .avi, .mov, .mkv, .jpg, .jpeg, .png, .bmp) plus .npy, .parquet, .h5, and .hdf5 data inputs.

Video files use native video playback. .npy, .parquet, player_joints_h5, and player_centroids_h5 inputs use specialized raster preview renderers.

Why did a sample ID change to `__2`?¶

When duplicate or missing IDs are loaded, the app normalizes them to unique IDs (for example clip_dup, clip_dup__2).

Where are localization label colors stored?¶

In application settings (QSettings), not in the dataset JSON.

Where are customized media controls stored?¶

Playback factors and relative-seek intervals from Edit → Settings… are application-wide QSettings preferences. They are not saved in or exported with dataset JSON.

Localization accept/reject key bindings on the Shortcuts settings page are also application-wide QSettings preferences. The defaults are Ctrl+Enter and Ctrl+Backspace; bindings must be non-empty, distinct, and free of conflicts with built-in shortcuts.

Where is the Dataset Explorer page size stored?¶

The value from Edit → Settings… → Dataset Explorer is an application-wide QSettings preference. It defaults to 500 and is not part of dataset JSON.

Why is HF upload disabled?¶

Upload is available only when a dataset JSON is currently opened from disk (not unsaved in-memory only).

Why does a recent dataset entry disappear?¶

If the file no longer exists, the app removes the stale entry from recents.
