Pro Editor is an excellent tool to share work with others. There are two main reasons why you'd want to do this:
You want to have a professional producer in your organization tweak an ad you created using Instant Ad or Create an Ad.
You need a bigger toolset to finesse your own or someone else's work and have the expertise to do so.
Here's you open an existing project in Pro Editor:
1. Go to Projects, choose the name of the person (yourself or another member of your organization) and open the project folder you or they created:
2. Right-click on the Project you're interested in, and choose "Pro Editor":
3. A new window will open and load the content of the Project. You are now able to work on each individual track of that Project:
4. When you're done editing the tracks, click on "Produce" to generate the audio. From their, you can either download the completed track or leave it in the Editor for the next person to pick up.
5. All changes will be saved in the Project (yours or someone else's) as "Pro-Session" and can be accessed by right-clicking.
You can also share or download the audio file:
