Update: November 2021
Flipaclip has just released their latest update, version 4.0.1. This update comes with bug fixes and improvements on both audio and video stabilization.
Starting with the audio, the version 4.0.1 update fixes an issue with audio sync on some clips. Additionally, audio is now better synchronized with the video, especially on clips with quick motion.
Moving onto the video stabilization, the update includes more powerful stabilization for clips with complex motion. The update also corrects an issue where stabilization would occasionally fail with clips that had sharp vertical movement.
Flipaclip's update also includes general improvements to the user interface. The version 4.0.1 update fixes an issue where the video would stop if the user tried to move the video window to the edge of the screen.
