VideoCapturAR

Introduction

This repository contains a Unity3D project designed for capturing videos in different resolutions on the HoloLens 2. It provides an easy-to-use interface for initiating video recordings and selecting resolutions. Internally, the Windows MediaCaptureAPI is utilized to allow capturing of different resolutions under different profiles. Using the VideoCaptureAPI provided by Unity3D only resolutions under the Legacy profile are recordable.

Supported Resolutions

2272x1278 1952x1100 1920x1080 1504x846 1280x720 1128x636 960x540 760x428 640x360 500x282 424x240

• Change language (EN/DE): Bring up your left hand, palm facing you. A menu will pop up right to your hand. Tap the button to switch between English and German
• Save video: Captured videos are automatically saved in he local application folder under the name video_{video count}_{resolution width}x{resolution height}.mp4. In case of name collisions, existing files are overwritten!
