Unable to export video from layers

At first it was only rendering the first frame, now I've managed to hit a shortcut or something and my timeline will only show vertically stacked.

Hi there,

Sorry to hear that Photoshop is not able to export video. Would you mind telling us the version of Photoshop and the operating system you're working on?

Also, could you please try resetting the preferences of Photoshop and let us know if that helps?

Note: Make sure that you back up all your custom presets, brushes & actions before restoring Photoshop's preferences. Migrate presets, actions, and settings
