Any 2D video you have taken in the past can be automatically converted to 3D video. You can enjoy the tremendous power and realism of 3D video that you can't taste with 2D video. This app also supports anaglyphs, so anyone can enjoy 3D video using red and blue glasses. This app supports not only videos stored on smartphones, but also video recording with camera. Taking TV shows and movie scenes with a smartphone to make them 3D, and the fun will be endless. For example, the aerial battle of the movie Star Wars and a YouTube video like an aerial shot of a drone are truly impressive. (Please be careful when downloading or publishing the copyrighted work of others.) [About Anaglyph] - If you have strong strabismus, use red / blue glasses to view in anaglyph mode. - Red and blue glasses can be easily made with cellophane, and can also be purchased online at low cost. - Those who can perform autostereoscopic viewing can also enjoy stereoscopic viewing by turning off the anaglyph mode. [Video not suitable for 3D] - You cannot get a three-dimensional effect for videos that have almost no movement. - Videos that do not move the camera or subject are inappropriate. - For example, a movie with a camera with a tripod and a small amount of motion is not suitable. [About autostereoscopic vision] This is a method of viewing the image of the left eye and the image of the right eye with the naked eye while feeling the three-dimensional image in three dimensions. There are two methods for autostereoscopic viewing: the parallel method and the cross method. The parallel method is a method in which the left image is viewed with the left eye and the right image is viewed with the right eye. The cross method is a method of viewing the left image with the right eye and the right image with the left eye. You can easily find out how to practice the parallel method and dating method by searching the web. Stereoscopic vision is said to improve the ability to focus with both eyes and help restore vision. It is thought to promote the movement of the eye muscles and visual field, thereby activating the brain. [Video source] - Camera shooting - Camera roll: Loading video [Settings] - Anaglyph mode: ON / OFF - Stereoscopic Image Layout: [1] [2] / [2] [1] Choose whichever is easier to see. - 3D Depth: Adjust with slider control If the 3D depth is too large, the left and right images will be misaligned. Conversely, if the 3D depth is too small, the stereoscopic effect will be poor. - Storage resolution: 20-100% of original resolution [output] - Save to camera roll: video, photo - Video and photo sharing: AirDrop, LINE, Facebook, Dropbox, Instagram, ...

[Features] ■ Simultaneous Playback of Multiple Dance Videos Compare a sample video and your own video side-by-side, or view videos shot from various angles all at once! Plus, the app automatically synchronizes the playback positions by analyzing the audio of your videos, making it easy to align the timing of different clips! ■ Loop Playback Set specific segments within a video for seamless loop playback! You can set any number of loop points. Perfect for repeatedly watching and practicing a specific movement from a sample performance! ■ Adjustable Playback Speed Change the speed from 0.1× to 1.0× in 0.1 increments! ■ Individual Video Volume Control Adjust the volume for each video from 0% to 100% in 10% increments. This is useful for balancing volume differences between multiple video sources! ■ Horizontal Flipping You can flip any video horizontally, ideal for mirroring the movements. [Example Use Cases] ・Copying Idol Dances Idol MVs and TV performances often feature camera cuts or close-ups that obscure the choreography. Collect multiple videos (MV, performance clips, etc.) and play them simultaneously with this app. You'll instantly see which video shows the full move, allowing for highly efficient practice! ・Side-by-Side Comparison of Sample and Personal Videos Comparing a sample video directly with your practice video makes it easier to spot where your movements deviate. Automatic playback synchronization ensures a perfect comparison, even if the videos are of different lengths! [Important Notes] ・This app plays videos saved in your Photos Library. It cannot play online videos such as those from YouTube. ・Due to device specifications, playback may become laggy if videos have a high resolution or if you play too many videos simultaneously. ・All features are available for free, but the free version has a limit on the number of projects (groups of videos for simultaneous playback) you can create. You can create as many projects as you like by purchasing the paid option, "Remove Project Limit."
