"Understanding the Basics of Video Editing Software Rendering"

Video editing software rendering is a fundamental and critical aspect of video production that converts our hours of filmed footage into a single, viewable video. Rendering takes raw video footage, effects, transitions, overlays, and more and blends them all together and compresses into a viewable format. For anyone involved in video production, understanding the basics of video editing software rendering is essential.

The Rendering Process

The video rendering process involves creating a final video file from your individual clips or footage. You might be mixing various types of media, including video, still images, graphic overlays, 3D animations, sound effects, voiceovers, and music tracks in one project.

During the rendering process, your video editing software combines all these elements and compresses them into a single file. It calculates all the data, applies the visual effects and sequences, compiles the backgrounds, extrapolates the pixels, blends the overlaying elements, and ultimately creates a single comprehensive and unified video file.

Rendering: Real-Time vs. Non-Real-Time

Video rendering can be categorized into two main types: real-time rendering and non-real-time rendering. Real-time rendering is usually associated with gaming and interactive graphics where images need to be computed from 3D information at an incredibly swift rate. On the other hand, non-real-time rendering is utilized in video editing where the software might take several hours to render a couple of minutes of high-quality video footage.

Render Settings

The quality, speed, and size of a rendered video are largely determined by render settings. There are dozens of formats, codecs, and resolutions. Common elements you will find in your render settings are:

  • Resolution
  • Frame rate
  • Bit rate
  • Audio settings

All these factors together affect both the output quality and the exports speed of your video.

Rendering and Exporting

Rendering and exporting are often confused, but they are different phases of the same process. Rendering is the process through which the software creates a preview of your project so that you can review or edit it, while exporting is the final step in post-production which generates the final product that viewers will watch.


Understanding the basics of video editing software rendering can dramatically improve your video editing skills. It helps you to improve efficiency and save time, and also enables you to produce higher-quality videos. The rendering process may seem highly technical and complex, but with a good understanding of the basics, you can become proficient in handling it.

Frequently Asked Questions

What does rendering do in video editing?

In video editing, rendering refers to the process whereby the computer processes the different elements of your video project into one unified final product.

What factors influence rendering speed?

Several factors can influence the speed of rendering, such as the video’s length, resolution, frame rate, the complexity of effects included, as well as the power of your computer’s CPU and GPU.

What is the difference between rendering and exporting?

In the context of video editing, rendering refers to the process of creating previews of your project for review or further edit, while exporting is the process of creating the final product for viewers to watch.

How does rendering improve the quality of a video?

Rendering does not necessarily improve the quality of a video. Rather, it translates your video project, including all its various components, into a single, unified file that can be watched seamlessly.

How can I speed up the rendering process?

There are a few ways to speed up the rendering process. These include reducing the video resolution, closing all other programs while rendering, increasing your RAM, using a faster storage drive, or upgrading your computer’s CPU or GPU.
