Export Reduced File Size Videos in DaVinci Resolve (3 Methods)

Reducing the file size of a video in DaVinci Resolve can be achieved by tweaking export settings. Here’s a step-by-step guide to ensure quality retention while minimizing the file size.

Method 1: Adjust the Resolution

Reducing the resolution of a video is a straightforward way to reduce file size, but it comes at the cost of quality.

Steps:
1. Go to the Deliver page.
2. In the Video tab, lower the resolution (e.g., from 4K to 1080p).
3. Export the video.

Note: This method is not recommended unless reducing resolution and visual quality is acceptable for your use case.

Method 2: Adjust the Quality

DaVinci Resolve offers preset quality levels—Least, Low, Medium, High, and Best.

Steps:
1. In the Deliver page, set Quality to Low or Least.
2. Export and evaluate the video.

Results from Testing:
- Low: Retains good quality with reduced file size (~20MB smaller).
- Least: Results in highly pixelated videos and is not recommended.

Method 3: Restrict Bitrate

Using the "Restrict to" option, you can cap the bitrate, directly influencing the file size.

Steps:
1. In the Deliver page, enable the "Restrict to" option.
2. Enter a lower bitrate value (e.g., 10,000 kbps for significant reduction).
3. Export the video.

Results from Testing:
- 10,000 kbps: Significant reduction in size (e.g., 139MB to 57MB) while retaining acceptable quality.
- 20,000 kbps: Moderate reduction (e.g., 139MB to 117MB) with excellent quality.
- 50,000 kbps: Minimal size reduction but near-original quality.

Best Practices

1. Start with Low Quality:
Export the video at "Low" quality first to check if the file size meets your requirements.
2. Experiment with Bitrate:
Use the "Restrict to" option to find the sweet spot where quality and file size are balanced.
3. Preview Before Final Export:
Always preview your exported file to ensure quality is acceptable.

Final Notes

The optimal settings for reducing file size vary by video. While "Low" quality or 10,000 kbps restriction works well in many cases, you may need to experiment with different settings depending on your video’s content and intended use.

By following these methods, you can effectively reduce the file size of your videos in DaVinci Resolve without compromising too much on quality.
