Full Guide to Upscale Video in Blender in 2025

Edited by Ava Wilson Aug 20, 2025 Enhance Video

Blender, known as a powerful 3D creation tool, is also capable of handling editing and upscaling tasks. It can be done through external AI models support. While primarily designed for animation and rendering, it allows you to process and enhance video quality. Nowadays, the demand for high-quality video upscaling is rising rapidly. Many creators are seeking ways to improve resolution without sacrificing visual quality. Upscaling helps transform low-resolution clips to more visually appealing content. This post will guide you through the process of how to upscale a video in Blender. We'll cover essential setup, understanding the workflow, and rendering the final upscaled video. This way, you can transform low-resolution footage into something detailed effortlessly.

Part 1. How to Use Blender to Achieve AI Video Upscaling

Requirement and Setup

Before upscaling a video in Blender, it's essential to prepare the right tools and setup. AI upscaling enhances video quality by rendering low-resolution frames and then using AI to upscale those frames to higher resolutions. To achieve this within Blender, you'll need to set up a few key components. These elements work together to allow Blender to render low-resolution content that gets upscaled via AI:

What You'll Need:

• Blender 3.1 or later, installed on your operating system.

• Google Colab to run Stable Diffusion/Real-ESRGAN upscaling notebooks.

• Stable Diffusion Colab Notebooks with img2img or video upscaling capabilities.

Input Requirements:

• Video rendered in low resolution.

• Saved as image sequence (PNG preferred).

Understanding the Upscaling Process

Blender renders each frame at a reduced resolution determined by the scale factor you set. It then upscale video using AI to the target resolution by applying super‑resolution. This approach trades raw rendering time for AI enhancement, resulting in faster time and a detailed image.

Important Note: Though it excels for single images, temporal consistency across frames can be less robust. Due to this, slight flickers may occur. So, testing on short clips first is recommended.

Rendering the Upscaled Video

After setting up Blender with the AI Upscaler add-on, the next step is rendering the upscaled video. This phase brings everything together, upscaling your video to the target resolution with enhanced detail. This will result in a high-resolution video that looks sharp and professional.

Here's how to upscale video in Blender:

Step 1. In Blender, navigate to the Edit tab and select the Preferences in the pull-down menu. Proceed to the Add-ons section and expand Render: AI Render - Stable Diffusion in Blender (patch). Ensure the Stable Diffusion Backend is set to Google Collab (cloud).

Step 2. Press Shift + F2 keys to access the Movie Clip Editor and open a video clip. In the timeline, set the end frame to 318 and the start frame to 1. Then, move to the Clip tab, select Prefetch Frames, and play the video to preview it.

Step 3. Next, press the Shift + F8 keys to open the Video Sequencer to upscale the video. Change the Sequencer option to Sequencer & Preview and add the imported video clip. Proceed to the Output Properties and configure resolution to 1080 px (x) and 1920 px (y).

Step 4. Switch to the Render section, expand the window, and click the Enable AI Random button. Scroll down to Advanced Options and select the upsclate option as your model. If needed, configure other settings to your preference. Once everything is set, click the Render tab and select Render Animation to save the upscaled version of your video.

Through Blender + Stable Diffusion in Google Colab, you can upscale video effectively. It's efficient, accessible, and increasingly powerful. But here's the deal: Using Colab is free but has session time limits. For long videos, consider a paid GPU or segmenting your render batches.

Part 2. Best Alternative to Blender

Part 3. FAQs about Upscaling Video in Blender

Can I denoise video in Blender??

Yes, you can denoise video in Blender using the Compositor's built-in denoising features. These include OpenImageDenoise, which reduces noise in rendered frames or imported footage.

Does upscaling improve video quality?

Upscaling can enhance perceived video quality, but it does not recreate the original lost detail. Picwand AI Video Upscaler reconstructs visuals, making them look clearer and higher resolution.

How long does it take to upscale a video?

If you're using Blender, upscaling can take a significant amount of time, ranging from minutes to several hours. In contrast, using Picwand AI Video Upscaler is much faster. It only takes a few seconds to a maximum of 30 seconds, depending on your video size.
