OBJ to MP4: Guide to Convert 3D Object to MP4

Converting a 3D OBJ model into an MP4 video is a great way to showcase your creative work. Whether you've designed a 3D object in software like Blender or Maya, or downloaded a ready-made asset, turning it into a video allows you to demonstrate rotations, animations, and different perspectives. MP4 videos are easy to share online or with clients, making them perfect for showcasing 3D designs. In this guide, we'll walk you through the basic process of rendering an OBJ file to MP4, along with tips for optimizing your export settings for the best quality video. Let's dive in!

Part 1. Understanding OBJ and MP4 File Formats

1. What is the OBJ File?

The OBJ file format is widely used in 3D modeling and design applications. It stores the geometry, textures, materials, and other key data needed to describe a 3D object or scene. OBJ files are open, editable, and compatible with most 3D software, making them a universal standard for transferring 3D data between applications.

Common uses include exporting animated objects from modeling programs and downloading 3D assets from online libraries. The OBJ format is ideal for storing complex 3D artwork while retaining fidelity.

2. What is an MP4 File?

MP4 is a digital multimedia file format that can contain video, audio, subtitles and more. It compresses video efficiently using advanced codecs while preserving quality. MP4s are a cross-compatible delivery format ideal for sharing and streaming online - they can play seamlessly on virtually any device.

Major sites like YouTube, social platforms, and even TV broadcast systems rely on MP4 files. Compared to bulky raw video, MP4s simplify uploading and downloading with reasonably sized files. The MP4 container supports advanced media features too.

3. Why Convert OBJ Files to MP4?

While capable of storing intricate 3D data, OBJ files have some limitations. They are inherently still images capturing a 3D object at a moment in time. To showcase animations, rotations or flythroughs, designers must export multiple OBJ files frame-by-frame. OBJ files also require 3D modeling software to view or edit, limiting accessibility.

Converting to MP4 video solves these drawbacks with a dynamic, easy-to-use format. Combining multiple views into a continuous movie makes manipulated 3D content far simpler to perceive. Smooth motion clearly showcases depth, intricate textures and sweeping camera angles. MP4 compatibility also enables instant online sharing - allowing 3D animations to be enjoyed on any platform with ease.

Part 2. Guide to Convert OBJ to MP4 for Free

1. Convert OBJ to MP4 using Blender

Blender is a popular free and open-source 3D creation suite that can render OBJ files into MP4 video. Follow these steps:

Step 1: Import OBJ File

Open Blender and click File > Import > Wavefront (.obj). Select your OBJ file and set the import parameters.

Step 2: Scene Setup

Organize your 3D objects in the scene and add cameras, lighting or materials as needed. Use the timeline editor at the bottom to set keyframes.

Step 3: Render Animation

Go to the Render properties and select output resolution, frame rate and encoding format. Click Animation and set the frame output range.

Step 4: Render OBJ to MP4

Click Render > Render Animation to open encoding settings. Select MP4 as the container and H.264 codec. Choose a filename and location to save your new MP4.

2. Export OBJ as MP4 in Autodesk Maya

Autodesk Maya's robust toolset can also render OBJ asset scenes into shareable MP4 video files:

Step 1: Bring in OBJ

In Maya, go to File > Import and choose your OBJ file. Select options like smoothing groups, normal or materials.

Step 2: Set Up Scene

Arrange the camera, lighting rigs, animations and output resolution in your Maya scene setup.

Step 3: Render Settings

Open the Render Settings window, select the Maya Software renderer, set your desired output format as H.264 and containers as MP4.

Step 4: Export MP4

Click Render > Batch Render to open the export settings. Set frame ranges and output details. Start the render to create your MP4.

Part 3. Convert OBJ to MP4 Online for Free

1. Image to STL

Image to STL is a popular online 3D file converter that also allows OBJ to MP4 translation. It is completely free and does not require software downloads or sign ups. Image to STL accepts over 50 3D file inputs including OBJ, BLEND, DAE and more. It can convert these source files into common outputs like STL, GLTF, GLB, USDZ and MP4.

The automated OBJ to MP4 conversion gives high quality results in fast turnaround times. Users can upload an OBJ file up to 100MB, customize animation lengths and image dimensions if needed, then download the converted MP4 direct to their device. Image to STL handles animated camera fly-throughs, texturing, lighting and materials during conversion. The simplicity makes Image to STL an ideal way for beginners to quickly turn OBJ artwork into shareable MP4 videos.
