[FREE] AI Video Editor - How To Use GLM 5.3 To Edit Videos FREE

Editing videos can take hours, especially when you need motion graphics, animated captions, and professional-looking effects.

But what if you could automate most of that work using AI without paying for an expensive video editor?

In this tutorial, I’ll show you how to use OpenCode with the free GLM 5.3 Flash model to edit videos using simple prompts. You’ll also learn how to create five different video editing styles, add captions, and generate animations without manually editing every scene.

The best part? You don’t need a paid Claude Code subscription to follow this workflow.

What You’ll Need

Before getting started, make sure you have:

• OpenCode: An open-source AI coding agent.
• GLM 5.3 Flash: The free AI model used in this tutorial.
• Video Editing Skills ZIP: Contains the skills, styles, and fonts needed for the editing workflow.
• A Video File: Any short clip you’d like to edit.
• A Computer: Windows or Mac with the required dependencies installed.

You won’t need a paid Claude Code subscription for the workflow demonstrated here.

Step 1: Download and Install OpenCode

First, visit the official OpenCode website.

OpenCode is an open-source AI coding agent that lets you work with AI models through a desktop application or terminal.

You have two installation options:

1. Download the desktop application for Windows or Mac.
2. Install OpenCode using the terminal commands provided on its website.

For this tutorial, we’re using the terminal installation method.

Open the OpenCode website, select the terminal installation option, and copy the installation command appropriate for your system.

Run the command in your terminal and let the installation finish.

Once installed, launch OpenCode by entering:

opencode

You’ll now see the OpenCode interface, where you can start working with AI models.

Step 2: Select the Free GLM 5.3 Model

Next, we need to configure the AI model that will handle our video editing workflow.

Inside OpenCode:

1. Type /model and press Enter.
2. Search for GLM 5.3 Flash Free.
3. Select the free version from the available models.

Make sure you’re choosing the free model rather than a paid option that requires billing information.

Adjust the Model Effort

For better results, we’ll also change the model’s effort setting.

1. Type / in OpenCode.
2. Search for effort.
3. Select the effort setting.
4. Change it to Max.

This is the configuration used in our demonstration.

Step 3: Download the AI Video Editing Skills ZIP

Now comes the important part.

To create animated videos, OpenCode needs the video editing skills and supporting resources used in this tutorial.

We’ve prepared a ZIP package containing the necessary skills, editing styles, and fonts.

Get the Video Editing Skills

The download link will be delivered to your inbox.

Step 4: Install the Video Editing Skills in OpenCode

Once you receive the ZIP file, open OpenCode.

Here’s how to install the skills:

1. Drag and drop the downloaded ZIP file into OpenCode.
2. Ask OpenCode to install the skills included in the ZIP package.
3. Follow the installation instructions provided by OpenCode.
4. Allow the tool to configure the required dependencies.

During setup, OpenCode installs and configures supporting tools, including Python libraries and FFmpeg, which are used for video processing and captions.

The installation may take a few minutes, depending on your computer and the required dependencies.

Once everything is installed, OpenCode will confirm that the setup is ready.

Step 5: Choose Your AI Video Editing Style

One of the coolest parts of this workflow is that you can choose from five different video editing styles.

1. Chalk Talk

A drawing-inspired editing style that presents information visually.

This can be useful for educational videos, tutorials, and explainers.

2. Creator Motion Graphics

Adds animated motion graphics to make your videos more engaging.

This is a great option for YouTube tutorials and creator-focused content.

3. Data Story

A style designed to communicate information using data-focused visuals.

Consider this option when your content includes statistics, numbers, or explanations.

4. Pop Info

Uses attention-grabbing informational graphics to highlight key points.

It’s worth experimenting with for videos where you want important information to stand out.

5. Software Walkthrough

Designed for software demonstrations and screen-recorded tutorials.

This style works well for explaining tools, applications, and technical workflows.

You can experiment with different styles depending on the type of video you’re creating.

Step 6: Upload Your Video and Start Editing

Now that OpenCode is configured, we’re ready to edit our first video.

For this demonstration, we’re using a short clip of approximately 20 seconds.

Follow these steps:

1. Drag and drop your video file into OpenCode.
2. Enter the prompt: Edit this video
3. Press Enter.
4. Let OpenCode load the installed editing skills.

OpenCode will then ask you a series of questions to customize the editing process.

Configure Your Editing Preferences

Here’s how we configured our example:

Setting	Selected Option
Remove silent sections	No
Remove mistakes and retakes	No
Video editing style	Creator Motion Graphics
Language	English
Burn captions into video	Yes
Graphics intensity	Light
Check-ins before final render	Yes

We selected Light graphics intensity for a quicker demonstration.

You can adjust these settings based on your video and editing preferences.

Once you’ve answered the questions, submit your selections to start the editing process.

Step 7: Let AI Edit Your Video Automatically

After submitting your preferences, OpenCode begins processing the video.

In our demonstration, it handled tasks such as:

• Transcribing the video.
• Running the required Python scripts.
• Planning the motion graphics.
• Adding animations based on the selected style.
• Preparing the final edited video with captions.

The workflow uses the installed skills along with the selected GLM 5.3 Flash model.

You can follow the process through the OpenCode interface as each task is completed.

Step 8: Preview and Download Your Edited Video

Once the editing process is complete, OpenCode creates an output folder containing the edited video.

In our example, the final file was named:

final.mp4

Open the file to preview your edited video.

How Long Does AI Video Editing Take?

For our demonstration, OpenCode took approximately 20 minutes to process a 19.8-second video clip.

The result included animated graphics and captions using the Creator Motion Graphics style.

Keep in mind that processing time can vary depending on your computer, video length, selected graphics, and workflow complexity.

You can also refine your prompts to control where animations appear or adjust the amount of motion graphics in your video.

Is GLM 5.3 Video Editing Really Free?

In this tutorial, we used the free GLM 5.3 Flash model through OpenCode without adding a payment card or purchasing a Claude Code subscription.

However, free model availability and usage limits may change over time. Always check the available models and terms before starting.

The editing workflow also requires the skills package and supporting software dependencies described above.

Final Thoughts

AI video editing is becoming an interesting option for creators who want to experiment with animations, captions, and automated workflows without doing everything manually.

With OpenCode, GLM 5.3 Flash, and the right editing skills, you can turn a simple video clip into an animated video using prompts and a few configuration choices.

The setup takes some initial effort, but once everything is installed, you can experiment with different video styles and customize the results.
