Need to rotate FLV video files to achieve the perfect orientation? This post will walk you through the detailed steps to rotate your FLV files to the desired angle. The tools used include MiniTool MovieMaker, Clipchamp online video editor, and Online Video Cutter.
Due to the end of Adobe Flash Player, FLV is no longer a popular video format today. In the past, FLV was primarily used for streaming online video content. Sometimes, you may need to rotate or edit your old FLV files for various reasons.
However, FLV is not a good choice for modern video editing software, and some applications can’t handle it. But don’t worry, some tools support this format and allow you to rotate FLV video files effortlessly.
