Changing the aspect ratio in DaVinci Resolve can be accomplished through three main methods: fully manual, fully automatic, or using custom presets. By understanding the specific needs of your project and following the step-by-step guides provided, you can easily modify the aspect ratio to achieve the desired visual effect in your video editing.
Every video or image has a defined width and height, and the relationship between these two dimensions is termed as the aspect ratio. Commonly, you might have come across values like 16:9 (often used for modern TVs) or 4:3 (reminiscent of older television sets). But there's more to it:
Aspect ratios like 2.35:1, 2:1, and 1920 × 1080 are common in the film industry. They represent the width and height of the screen. In other words, they define how wide and tall the video will appear.
That said, the fully manual method gives you complete control but can be time-consuming. In my opinion, it's best for those who want precise adjustments.
Before committing to an aspect ratio, it's always a good idea to preview it. DaVinci Resolve offers a feature called “Safe Area” that lets you visualize different aspect ratios on your footage. This way, you can play around with various ratios and see their impact on your video, ensuring you make an informed decision.
DaVinci Resolve offers built-in templates for common aspect ratios. How about using these templates to save time? It seems that this method is perfect for those who want a quick solution.
Furthermore, this method is user-friendly and ideal for those who are new to video editing. Nevertheless, it might not offer the same level of customization as the manual method.
What if you want to create custom aspect ratios? DaVinci Resolve allows you to save custom presets. Let's explore how to do this.
In addition, this method combines the best of both worlds, offering customization and convenience. On the other hand, it requires a bit more understanding of DaVinci Resolve's settings.
Sometimes, a project demands the use of multiple aspect ratios. This can be a bit tricky, but with DaVinci Resolve, it's manageable:
Black bars (often seen at the top and bottom of videos) can sometimes detract from the viewing experience. If you're aiming for a full-screen look without these bars, here's how:

Aspect ratio is the ratio of the width to the height of an image or screen. In DaVinci Resolve, you can work with various aspect ratios like 16:9, 21:9, 32:9, etc. It's a crucial element in video editing, as it affects how the video is displayed on different devices. For instance, 16:9 is a common aspect ratio for modern TVs and monitors.
To change the aspect ratio in DaVinci Resolve, you can use the "Output Blanking" option on the Color tab. This allows you to select common aspect ratios such as 1.33, 1.66, 1.77, 1.85, 2.0, 2.35, 2.39, and 2.40. If you need custom aspect ratios, there are tools like Digital Rebellion's Aspect Ratio Matte Creator that can generate overlays.
The "K" in resolutions like 2K and 4K refers to how many thousand pixels wide a resolution is. For 2K, it's 2,048 pixels wide. UHD 4K, or 3840x2160, is a standard for 4K TVs, while 4K in the context of movies is often 4096x2160. Both are commonly referred to as 4K, even though the numbers are slightly different.
Black bars, known as "pillarboxing" (sides) or "letterboxing" (top and bottom), can be added through the "Output Blanking" option in the Color tab. This allows you to create a cinematic look or fit a video into a specific aspect ratio.
DaVinci Resolve is "Resolution Independent," meaning it can easily scale between different resolutions. However, standard video resolutions must be even and evenly divisible by 4, 8, or 16. If you're trying to use a non-standard resolution, it may not be selectable in Resolve.
If you've accidentally changed the aspect ratio and want to restore it, you can adjust the custom timeline resolution in Project Settings using the Resolution button or Shift-9. You can also check the settings under Project Settings -> Master Settings -> Timeline resolution and Pixel aspect ratio.
In DaVinci Resolve Lite 10, if you're facing issues with pixel aspect ratio options like "square" and "cinemascope," you may need to adjust the settings for your specific HD or 2K options. You can also refer to the manual or consult the Blackmagic Forum for specific guidance.
In DaVinci Resolve 16, if you've altered the aspect ratio and need to restore it, you can click the Tools button on the left-middle of your screenshot. If the Aspect Ratio/Display is still wrong, you can change the custom timeline resolution in Project Settings or use Shift-9. More details can be found on the Video Production Stack Exchange.
