VideoPorter vs Markdown Viewer Mobile

VideoPorter is a user-friendly smartphone application designed to simplify and revolutionize camera tracking in non-professional settings. Using the built-in LiDAR technology of an iPhone or iPad Pro, VideoPorter captures live scenes while simultaneously recording precise camera movement data. This tracking information is embedded directly into the video, making it ideal for use in augmented reality (AR) environments in your broadcaster. Each recording includes tracking and geolocation data, along with the video description, all stored locally on your device. You can preview the videos before sending them to the channel you want so they can use it as an AR background with that same tracking. To assist with framing, VideoPorter features a customizable silhouette overlay that acts as a visual guide during recording. This ensures that any person integrated into the AR scene appears correctly positioned and proportioned in the final video.
