I am working on my very first project in Da Vinci Resolve.
I have created a new project and dragged two videos, one .mp4 and one .mkv, into the Media section of the Edit window. I have then dragged both videos into the timeline. Now, I want to zoom out the size of the .mp4, such that I can have this video be located at the bottom right of the .mkv, which fills the whole screen. To achieve this, I have clicked on the .mp4 video and then navigated to the Inspector. I am changing the zoom inside the inspector, but nothing happens.
I have no clue what might be causing this issue. I have tried this out previously with 2 .mkv files and it worked. Then, yesterday, it seemed to be working for the .mkv, but not for the .mp4. Now, neither the .mkv nor the .mp4 can be zoomed out from inside the Inspector.
I am probably forgetting about something really obvious, but I would appreciate help.
