Learn how to set the aspect ratio for the timeline or change it while editing a video.
When you add a media file to start a new video editing project, Firefly prompts you to name the project and choose how to set the Timeline aspect ratio. You can either manually select a predefined aspect ratio or use the Automatic option to automatically fit the footage being imported.
You can also change the timeline's aspect ratio while editing a video, even after media files have already been added to the timeline.
Tip
You can also use the Properties icon when there are no existing timelines in the project to open the Timeline properties panel.
The Timeline properties panel gets enabled.
Use the Aspect ratio dropdown menu to select one of the presets.
