How to Convert 720p 3D Video to 1080p Video File?

3D video technology has opened up new immersive viewing experiences, but it comes with technical challenges. One common issue is compatibility between different 3D video formats. If you own a 720p Top-and-Bottom (TaB) 3D video and want to upgrade it to a 1080p Side-by-Side (SbS) format for better display on modern 3D TVs or VR headsets, you might wonder how to do it efficiently and without quality loss.

This article addresses that specific problem: how to convert 720p TaB 3D video into 1080p SbS 3D format, ensuring a seamless visual experience. Many users face playback issues or poor resolution when trying to play TaB videos on devices optimized for SbS format. Unfortunately, many tutorials rely on professional software like Adobe Premiere Pro or FFmpeg, which may be complex for average users.

In this guide, we provide 5 practical and unique solutions to achieve this conversion, including a simplified yet professional method using iDATAPP 3D Converter. All methods include clear steps and visual aids.

Why Convert TaB 3D to SbS 3D and Upgrade to 1080p?

• Compatibility: Many modern devices and 3D glasses prefer SbS format.
• Visual Quality: 1080p resolution offers better depth perception and clarity.
• Device Optimization: Some smart TVs or VR players interpret SbS better than TaB.
• Editing Flexibility: SbS is easier to manage in video editors.

Method 1: Use iDATAPP 3D Converter (Recommended)

The most efficient method is using iDATAPP 3D Converter, a specialized tool designed to convert 3D formats. It supports converting 720p Top-Bottom 3D videos to 1080p Side-by-Side without manual frame manipulation or command-line tools.

Method 2: Manual Frame Splitting Using AviSynth + VirtualDub

This method involves using AviSynth scripting to manually split the TaB frames, resize them, and stack them side-by-side. It’s more complex but gives full control.

Step 1: Install AviSynth and VirtualDub

• AviSynth: http://avisynth.nl/
• VirtualDub: https://virtualdub.org/

Step 2: Create AviSynth Script (AVS)

Step 3: Open Script in VirtualDub

File > Open Video File > your .avs script

Step 4: Set Compression and Export

• Video > Compression > Xvid/MP4 codec
• File > Save as AVI

Method 3: Using Blender for Precise Frame Control

Blender isn’t just for 3D modeling—it can be used to edit video frames and rearrange 3D videos into Side-by-Side format.

Step 1: Install Blender

Step 2: Open Blender > Video Editing Workspace

• Switch to "Video Editing"
• Add your 720p TaB video as a strip

Step 3: Duplicate Strip & Crop

• Use transform modifiers to crop top and bottom halves
• Resize each half to 960x1080

Step 4: Arrange Side by Side

• Move cropped halvs to left and right
• Preview result

Step 5: Render to 1080p Side-by-Side

• Set output resolution to 1920x1080
• File > Render > Render Animation

Method 4: FFmpeg Command Line (Advanced Users)

FFmpeg allows batch conversion via command line. This method is fast and scriptable but requires technical precision.

Step 1: Install FFmpeg

Step 2: Run the Command

Step 3: Wait for Encoding

• Output will be 1080p SbS file

Method 5: Frame-by-Frame Extraction and Recombination (Manual)

For educational or one-time conversion purposes, this method extracts frames as images, edits them manually, and recompiles into a video.

Step 1: Extract Frames with FFmpeg

Step 2: Use ImageMagick to Crop and Resize

Step 3: Batch Process with Bash or Python Script

Step 4: Recompile to Video
