Using nested sequences for cinematic black bars in Premiere
1. Duplicate your sequence

First, you need to duplicate your final sequence in Premiere Pro. This copy will serve as the canvas for you to add in black bars.
2. Adjust your sequence resolution
Then, navigate to ‘Sequence’ and select ‘Sequence Settings’ for your original sequence.

Next a prompt to adjust the resolution according to your chosen aspect ratio should appear. For the 2:35:1 ratio, you can opt for either 1920 by 810 pixels for 1080p HD or 3840 by 1620 pixels for 4K UHD. These settings ensure that your final export includes the black bars.

3. Review your project
Once you update the resolution, review your original sequence. Pay close attention to the position of each clip to make sure they align seamlessly within the new resolution. This step helps to maintain the visual integrity of your project.

4. Delete the duplicate content
Once you’re happy with how your sequence looks, select your duplicated sequence and delete all of its content. No, you didn’t misread that – delete it all. It might feel counterintuitive, but this is a necessary step in the process of adding cinematic black bars to your project.

5. Drop in your original sequence
Now it’s time to bring the magic to life. Drag and drop your 2:35:1 sequence into the full-resolution HD or 4K timeline.

6. Export your full resolution sequence
Finally, once your project is looking how you want it to, it’s time to export your final cut. Navigate to the settings and export the full-resolution sequence.
