What should I render at as a mixed resolution master for a 4K video to minimize the file size while maintaining optimal image quality for editing and distribution?

When rendering mixed resolution footage, it is recommended to match the project's frame rate to the most common frame rate in the timeline.

DaVinci Resolve's "Individual Clips" setting allows each clip in the timeline to be rendered at its original frame rate.

Rendering mixed frame rate footage at its original frame rate can reduce frame rate conversion issues and maintain image quality.

Frame blending can be used in DaVinci Resolve to smooth out transitions between clips with different frame rates.

If a project's output is 4K, it's best to render at 4K even if some footage is 1080p, as upscaling lower resolution footage can result in lower image quality.

When converting lower resolution footage to a higher resolution project, it's recommended to convert it beforehand to maintain image quality.

For YouTube, the recommended render settings are 1080p at 24, 25, or 30fps, depending on the project's frame rate.

When working with multiple frame rates and aspect ratios, it's recommended to maintain the highest possible resolution and frame rate throughout the project.

When converting footage to a different frame rate, it's recommended to avoid converting from higher to lower frame rates, as this can result in lower image quality.

For optimal image quality, it's recommended to avoid reducing the frame rate of high-speed footage, as this can result in motion blur and loss of detail.

The Kinemacolor process, an early 20th-century color film process, used a mixed frame rate of 32 and 40 frames per second to create a color effect.

The variable frame rate of film projectors created a "judder" effect that was reduced with the introduction of fixed frame rate projectors.

In video games, a high frame rate is preferred for smoother gameplay, while a lower frame rate can be used to create a deliberate "cinematic" effect.

Rendering mixed frame rate footage can be computationally intensive, as it requires processing each clip at its own frame rate.

Higher frame rates can result in a more detailed and realistic image, but require more storage space and processing power.

The frame rate of a video can affect the perception of motion, with higher frame rates resulting in smoother motion and lower frame rates resulting in a "choppier" motion.

In live sports broadcasting, a high frame rate is preferred to capture fast-moving action and reduce motion blur.

The use of different frame rates in film and television can create a deliberate visual effect, such as slowing down or speeding up time.

The Oculus Rift virtual reality headset has a refresh rate of 90 Hz to reduce motion sickness and provide a smoother visual experience.

High-speed cameras can capture footage at thousands of frames per second, allowing for slow-motion playback and detailed analysis of fast-moving events.
