DaVinci Resolve is a widely-used post-production application, known for its versatility and capabilities. However, it can be challenging to grasp, particularly for those new to video editing. One essential skill that’s good to master is how to export transparent backgrounds in DaVinci Resolve.
This article serves as a step-by-step guide to help amateur video editors navigate this process.
Preparations for exporting a transparent background on videos
- Familiarize yourself with DaVinci Resolve: Spend some time exploring the software, its interface, and available tools. Watch tutorials, read user guides, or take an online course to get comfortable with DaVinci Resolve’s features and capabilities.
- Update DaVinci Resolve: Ensure you are using the latest version of the software to access all the features and improvements that come with each update.
- Create a project template: If you plan to work on multiple projects with similar settings or formats, create a project template in DaVinci Resolve with your preferred settings. This template can save time and ensure consistency across your projects.
- Backup your project: Regularly save and back up your project files to prevent data loss in case of unexpected software crashes or computer issues.
Exporting a transparent background on video in DaVinci Resolve
1. Import the video and add it to the timeline
Begin by importing the video you wish to edit and adding it to the timeline. The timeline enables you to edit multiple media clips using various tools, such as creating a transparent background on videos, also known as the “Alpha Channel“. Once your media clips are in the timeline, you can commence editing.
2. Ensuring your clip has the correct attributes
First, verify that your video clip includes an alpha channel or transparency. Right-click on the clip in the timeline and select “Clip Attributes“. In the “Attributes” tab, scroll down to “Alpha Mode” and confirm that it is set to “Straight” or “Premultiplied“. If the alpha channel is not enabled, exporting a transparent background will not be possible.
3. Go to the deliver page and adjust the render settings
Once you have adjusted the background alpha and edited the clips to your satisfaction, proceed to the deliver page to modify the render settings. These settings must be configured specifically to export a video with a transparent background.
Follow these steps:
- Go to “Custom Export“.
- Name the file you are working on and select the desired save location.
- Under “Video“, check the “Export Video” box.
- For “Format“, choose your preferred option; many users opt for the default setting, “QuickTime“.
- Under “Codec“, select either “Apple ProRes” or “HVEC H265“.
- For “Type“, choose “Apple Pro Res 4444 XQ“.
- Check the “Export Alpha” box.
- Click “Add to Render Queue“.
- Click “Render“.
4. Import the new video to DaVinci Resolve
After completing the steps above, the video should now have a transparent background. Import the updated video back into DaVinci Resolve to confirm its transparency. If the background remains opaque, you may have missed a crucial step in the render settings. Review the instructions above to ensure you have followed them accurately.

Frequently Asked Questions (FAQ)
What is the Alpha Channel in video editing and why is it important?
The Alpha Channel in video editing refers to the transparency information of a video or image. It is an additional channel besides the red, green, and blue (RGB) channels that define color. The Alpha Channel represents the opacity levels of each pixel, ranging from fully transparent (0) to fully opaque (255). This channel allows for the seamless integration of multiple layers, graphics, and visual effects, enabling editors to create more complex and visually appealing compositions.
What are the differences between the Apple ProRes and HVEC H265 codecs?
Apple ProRes is a high-quality, lossy video compression codec developed by Apple Inc., designed to maintain excellent video quality and performance during post-production editing. ProRes codecs are widely used in professional video production because they retain a high level of detail and color accuracy while keeping file sizes manageable.
HVEC (High-Efficiency Video Coding), also known as H.265, is a video compression standard that provides better data compression compared to its predecessor, H.264. HVEC H265 is designed to deliver high-quality video at lower bit rates, making it suitable for streaming high-resolution videos while consuming less bandwidth and storage.
Are there any limitations when exporting videos with transparent backgrounds in DaVinci Resolve?
One limitation when exporting videos with transparent backgrounds in DaVinci Resolve is that not all codecs and file formats support alpha channels. Ensure you choose a compatible codec, such as Apple ProRes or HVEC H265, and a file format like QuickTime to successfully export your video with a transparent background.
Why would I need to export a video with a transparent background?
Exporting a video with a transparent background is beneficial when you want to overlay it onto other footage, images, or graphics without blocking the underlying content. This technique is commonly used in motion graphics, visual effects, and compositing to create more intricate and visually appealing videos.
What are the differences between the “Straight” and “Premultiplied” Alpha Modes in DaVinci Resolve?
In DaVinci Resolve, the “Straight” and “Premultiplied” Alpha Modes refer to different ways of handling transparency and color information in the video:
“Straight” Alpha Mode: In this mode, the color and transparency information are stored separately. This method is ideal for maintaining accurate colors and clean edges, particularly when compositing multiple layers or when the transparent elements have varying levels of opacity.
“Premultiplied” Alpha Mode: In this mode, the color information is pre-multiplied by the alpha channel, meaning that the color values are affected by the transparency level. This method can sometimes cause color fringing or halo effects around the edges of the transparent elements, but it can be faster to process in certain cases.
Final Thoughts
Navigating DaVinci Resolve can be challenging, especially for those new to the platform. Exporting a video with a transparent background may initially seem daunting, but by following the steps outlined above in the most recent version of the software, you will have your video on the alpha channel in no time.
