Image Sequence to Video - Blender Addon

An addon to speed up the rendering workflow where image sequences of rendered frames can be converted to video within the same Blender file you're working on, without any setup required.

What It Does

The addon reads your render framerate, resolution, and render output folder, then presents quick options for video encoding. It can use FFmpeg if installed, or launch a headless Blender process and render using Blender's own video encoder.

The addon mimics Blender's native video rendering and can preserve alpha channel for compatible formats. It's useful for working with rendered image frames and quickly converting them to videos to share or use.

Installation

1. Download the latest release (the image_sequence_to_video folder as a zip)
2. Open Blender and go to Edit > Preferences > Add-ons
3. Click Install... and select the downloaded zip file
4. Enable the addon by checking the checkbox

Usage

Access the addon from:

• Render Properties panel (camera icon) > Image Sequence to Video section
• Render menu > Image Sequence to Video

Click Convert Image Sequence, browse to your image sequence (select any file in the sequence), configure settings, and convert.

FFmpeg Encoder (Fast)

When FFmpeg is installed and detected, you can use it for direct, fast encoding.

Blender Encoder (Full Control)

Use Blender's Video Sequence Editor for encoding when you need color management options or don't have FFmpeg installed.

Conversion Progress

The panel shows real-time progress during conversion.

Completion

When done, quickly open the video or output folder directly from the panel.

Features

• Dual Encoder Support: FFmpeg for speed, Blender VSE for full control
• Codecs: H.264/MP4, VP9/WebM, AV1/WebM, ProRes/MOV
• Auto-detection: Reads your scene's framerate and render output path
• Alpha preservation: WebM and ProRes formats support transparency
• Output versioning: Never overwrites existing files
• Color management: View transform, look modifiers, exposure/gamma (Blender mode)
• Cross-platform: Windows, macOS, Linux

File Structure

After conversion, files are organized as:

your_render_folder/
├── frame_0001.png
├── frame_0002.png
├── ...
├── videos/
│   └── frame_v001.mp4
└── setup_files/
    └── frame_v001_setup.blend

Requirements

• Blender 5.0 or later
• FFmpeg (optional, for fast encoding)
  • Windows: Download from ffmpeg.org and add to PATH
  • macOS: brew install ffmpeg
  • Linux: sudo apt install ffmpeg

Troubleshooting

FFmpeg not found: Install FFmpeg and add it to your system PATH, or use the Blender encoder.

Conversion seems stuck: Check the System Console (Window > Toggle System Console) for progress details.

Alpha not preserved: Use VP9/WebM or ProRes codec and enable "Preserve Transparency".
