How do you change the aspect ratio of your project?

Changing the aspect ratio of your project in AVID Media Composer primarily involves accessing the project configuration dialog. This method allows you to define the overall settings of your project, including its aspect ratio, which is essential for ensuring that the final output appears correctly on various display devices. Adjusting settings in the project configuration dialog directly impacts how media is displayed throughout your editing process, ensuring consistency across all clips and sequences.

While other methods like using the transformation tool or adjusting clip parameters can affect the appearance of individual clips or sequences, they do not change the overall project settings. Exporting with custom settings may offer flexibility in output options, but it primarily pertains to how the project is delivered rather than altering the fundamental aspect ratio within the editing environment. Thus, the project configuration dialog is the critical tool for setting and maintaining the desired aspect ratio for the entire project.
