Apply any transition or any other video effect available in your Adobe Premiere menu program to polish your edited visuals. Your options depend on the version of your program and how many plug-ins you have for it.
Make title texts and movie credits for your edited work's opening and closing billboards.
Finalize and mix your audio requirements for your project. These include the dialogue, sound effects, atmosphere sound, music and other sound elements for the movie. If your master audio track is edited in a separate sound-editing program, simply import the audio file to your Adobe Premiere editing project, then drag it to the program's audio-time line. Playback the video with the laid-in audio to check the synching before moving to the next step.
Render your edited video if the said process is not yet complete. Adobe Premiere can provide real-time or almost real-time rendering of the audio and video elements in your timeline. In some cases, depending on the technical specifications of your computer and the version of the program you have, rendering may take a longer time, especially if you are editing high-definition (HD) video and/or your movie is visual effects-heavy.
Export the movie in your desired video file format. From the "File" menu, click "Export" and wait for the "Export Window" to appear. Select the file format from the drop-down menu. Popular file format selections you can choose from include QuickTime Movie, Real Media, Windows Media, Flash and a variety of MPEG formats. Configure the settings of your selected format, and click the "Save" button to start the exporting process.
Wait for the exporting process to finish. Depending on your computer's technical specifications, your video's configuration and the running time of your output video, the exported file might be available anywhere from a few minutes to a number of hours.
