When an editor prepares a project in DaVinci Resolve, video resolution affects nearly every part of the workflow: timeline performance, framing, export quality, platform compatibility, and file size. Whether the project is being made for YouTube, Instagram, TikTok, broadcast, or a cinema-style master, knowing how to change resolution correctly helps avoid blurry exports, cropped footage, and unnecessary render issues.
TLDR: In DaVinci Resolve, video resolution can be changed in the Project Settings under Master Settings, where the timeline resolution is selected. For individual timelines, the editor can also open Timeline Settings and adjust the resolution independently. Before exporting, the resolution should be checked again on the Deliver page to make sure the final render matches the intended format.
Understanding Resolution in DaVinci Resolve
Before changing settings, it helps to understand what “resolution” means inside DaVinci Resolve. Resolution refers to the number of pixels in a video frame, usually written as width by height. For example, 1920 x 1080 is Full HD, 3840 x 2160 is 4K UHD, and 1080 x 1920 is vertical Full HD for mobile platforms.
DaVinci Resolve separates resolution into a few important areas. The timeline resolution determines the working canvas for editing. The source clip resolution is the original size of imported footage. The render resolution controls the final exported video size. These settings can be the same, but they do not have to be.
For example, an editor may use 4K footage on a 1080p timeline to reframe shots without losing quality. Another editor may create a vertical 1080 x 1920 timeline from horizontal footage for social media. Understanding this distinction makes the process much easier.
Step 1: Open the Project in DaVinci Resolve
The editor should begin by opening DaVinci Resolve and loading the project that needs a resolution change. If the project has not been created yet, the editor can start a new project from the Project Manager.
Once the project is open, the resolution can be changed before editing begins or after clips have already been placed on the timeline. However, changing the resolution early is usually recommended because it prevents scaling and framing surprises later in the edit.
Step 2: Open Project Settings
The main place to change timeline resolution is the Project Settings window. In most layouts, the editor can find it by clicking the small gear icon in the bottom-right corner of the interface.
After selecting the gear icon, the Project Settings window appears. This window contains several categories, including master settings, image scaling, color management, capture, playback, and more. For resolution changes, the editor should stay in the Master Settings section.
Step 3: Change the Timeline Resolution
Inside Master Settings, the editor will see a section called Timeline Format. This is where the default project timeline resolution is controlled. A dropdown menu allows common options such as:
- 1280 x 720 HD for lower-resolution web video
- 1920 x 1080 HD for standard Full HD projects
- 3840 x 2160 Ultra HD for 4K UHD projects
- 4096 x 2160 DCI 4K for cinema-style projects
- Custom for vertical, square, or unusual formats
To change the resolution, the editor selects the desired option from the dropdown. If a custom resolution is needed, the editor can enter specific width and height values manually.
For example, a vertical social media video may use:
- 1080 x 1920 for Instagram Reels, TikTok, or YouTube Shorts
- 1080 x 1080 for square social media posts
- 1920 x 1080 for standard widescreen video
After the resolution is selected, the editor should click Save to apply the project settings.
Step 4: Set the Timeline Frame Rate Carefully
Although this article focuses on resolution, the editor should also check the timeline frame rate while still in the Master Settings panel. Frame rate and resolution are often configured at the same time, and DaVinci Resolve may restrict frame rate changes after media has been added to a timeline.
Common frame rates include 23.976 fps, 24 fps, 25 fps, 30 fps, and 60 fps. The editor should choose a frame rate that matches the footage or the final delivery requirement. This does not directly change the resolution, but it helps maintain smooth playback and proper export settings.
Step 5: Change Resolution for a Specific Timeline
In some projects, the editor may need different timelines with different resolutions. For example, a long-form YouTube video may be edited in 1920 x 1080, while shorter clips from the same footage may be prepared in 1080 x 1920 for social media.
DaVinci Resolve allows individual timelines to use custom settings instead of relying only on the global project settings. To do this, the editor can locate the timeline in the Media Pool, right-click it, and choose Timeline Settings.
In the Timeline Settings window, the editor should disable Use Project Settings. Once disabled, custom resolution options become available. The editor can then set the timeline resolution, pixel aspect ratio, frame rate, and other timeline-specific options.
This method is useful when a project contains multiple deliverables. Instead of creating separate projects for every platform, the editor can manage several timelines inside one Resolve project.
Step 6: Adjust Image Scaling Settings
Changing resolution affects how footage fits inside the timeline. If a 4K clip is placed on a 1080p timeline, DaVinci Resolve may scale it down. If a horizontal clip is placed on a vertical timeline, it may appear cropped or surrounded by blank space.
To control this behavior, the editor can return to Project Settings and open the Image Scaling section. Several useful options are available, including:
- Scale entire image to fit: The whole image appears inside the frame, which may create borders.
- Scale full frame with crop: The image fills the frame, but some edges may be cropped.
- Stretch frame to all corners: The image is stretched to fit, which can distort the footage.
- Center crop with no resizing: The image stays at its original scale and may be cropped by the timeline frame.
For most professional edits, Scale full frame with crop or Scale entire image to fit are the safest options. The best choice depends on whether the editor prefers to fill the frame or preserve the entire shot.
Step 7: Reframe Clips After Changing Resolution
After the timeline resolution is changed, clips may need to be repositioned or resized. This is especially common when converting a horizontal video to a vertical format. A subject that looked centered in a widescreen frame may appear too far left or right in a vertical timeline.
The editor can select a clip on the timeline and open the Inspector. Under the Transform controls, settings such as Zoom, Position X, Position Y, and Rotation Angle can be adjusted.
For interviews, tutorials, product shots, or social media edits, careful reframing is important. The editor should check each important shot to make sure faces, text, logos, and key visual elements remain visible.
Step 8: Use Output Blanking if Needed
Sometimes an editor wants a cinematic look with black bars at the top and bottom of the frame. In DaVinci Resolve, this can be done using Output Blanking rather than changing the timeline resolution itself.
Output Blanking is available from the top menu under Timeline, then Output Blanking. The editor can choose a common aspect ratio such as 2.39 for a widescreen cinematic appearance.
This does not truly change the pixel resolution of the video. Instead, it masks part of the frame. It is useful for stylistic presentation, but not the same as setting a new timeline size.
Step 9: Check Resolution on the Deliver Page
The final step is to confirm the export resolution. Even if the timeline resolution is correct, the editor should check the Deliver page before rendering. The Deliver page controls the final file that will be created.
In the Render Settings panel, the editor can choose a preset or create custom settings. Under video settings, there is usually a Resolution option. It may automatically match the timeline, but it can also be changed manually.
For a clean workflow, the render resolution should usually match the timeline resolution. If the timeline is 1920 x 1080, the export should normally be 1920 x 1080. If the timeline is 1080 x 1920, the export should also be 1080 x 1920.
Recommended Resolutions for Common Platforms
Different platforms have different preferred formats. The editor can use the following list as a general guide:
- YouTube standard video: 1920 x 1080 or 3840 x 2160
- YouTube Shorts: 1080 x 1920
- Instagram Reels: 1080 x 1920
- Instagram square post: 1080 x 1080
- TikTok: 1080 x 1920
- Facebook video: 1920 x 1080 or 1080 x 1920
- Cinema DCI 4K: 4096 x 2160
- Ultra HD 4K: 3840 x 2160
Common Problems When Changing Resolution
One common issue is that clips appear zoomed in after the resolution changes. This usually happens because the scaling option is set to crop the footage. The editor can fix it through Image Scaling or by adjusting the clip’s zoom in the Inspector.
Another issue is black bars appearing around footage. This often means the source footage and timeline have different aspect ratios. The editor must decide whether to keep the full image with borders or crop the image to fill the frame.
A third issue is exporting at the wrong size. This happens when timeline settings are correct, but the Deliver page uses a different render resolution. Checking export settings before rendering prevents this mistake.
Best Practices for Changing Resolution
- Set resolution early: Choosing the correct timeline resolution before editing saves time later.
- Match the final platform: The timeline should be built for the intended delivery format.
- Use higher-resolution footage when possible: 4K footage on a 1080p timeline provides room for reframing.
- Check every important shot: A resolution change can alter composition and cropping.
- Confirm export settings: The Deliver page should match the intended final resolution.
FAQ
Can DaVinci Resolve change a video from 1080p to 4K?
Yes, DaVinci Resolve can export a 1080p video as 4K by changing the timeline or render resolution. However, this does not add true 4K detail. It only upscales the image, so the result may not look as sharp as native 4K footage.
How does an editor make a vertical video in DaVinci Resolve?
The editor can set the timeline resolution to 1080 x 1920 in Project Settings or Timeline Settings. After that, horizontal clips can be reframed using the Inspector so the subject fits properly in the vertical frame.
Why is the resolution option greyed out?
Some settings may be locked if the timeline is using project settings or if certain timeline properties have already been established. The editor can right-click the timeline, open Timeline Settings, disable Use Project Settings, and then adjust custom settings.
Should export resolution always match timeline resolution?
In most cases, yes. Matching export resolution to timeline resolution helps avoid unexpected scaling, cropping, or quality loss. Exceptions may occur when a separate delivery format is required.
Does changing timeline resolution affect original media files?
No. Changing resolution in DaVinci Resolve does not alter the original video files. It only changes how the footage is displayed, edited, and exported within the project.
What is the best resolution for YouTube?
For standard YouTube videos, 1920 x 1080 is a reliable Full HD option, while 3840 x 2160 is ideal for 4K uploads. For YouTube Shorts, the preferred format is usually 1080 x 1920.
