This is an app that allows you to create videos by synthesizing photos and audio, from formats such as mp3 and m4a. ■ High-Speed Export Performance Unlike full-fledged video editing software, the internal conversion process is simple, resulting in high-speed conversion. ■ Choose the Output Aspect Ratio You can choose whether to maintain the pixel count of the input images during output or automatically adjust it to common ratios like 1920 x 1080.
