In Adobe Premiere Pro, which panels are most likely used to create a picture-in-picture effect between two overlapping video tracks?

Creating a picture-in-picture effect in Adobe Premiere Pro primarily involves manipulating the video clips' positioning and scaling within the sequence. The Effect Controls panel is essential for this task, as it allows you to adjust the position and scale of the video clips individually. You can change the size of one video clip to make it smaller and position it accordingly on the screen, effectively layering it over another clip.

The Program Monitor is the display where you can visually see the outcome of your edits in real-time. It provides a live view of how the clips interact, enabling you to make precise adjustments while observing the results immediately.

By using both the Effect Controls and the Program Monitor together, you can achieve the desired positioning and scaling for the picture-in-picture effect. This combination is crucial for fine-tuning the aesthetics of the layered video tracks and ensuring they appear correctly in the final output.
