“Adobe Media Encoder FLV Source Compression Type Not Supported” Issue Fix

Adobe Media Encoder is a powerful tool used by video professionals to encode, transcode, and compress video files into various formats. While it offers a wide range of capabilities, users sometimes encounter issues with specific file formats, such as FLV (Flash Video).

Understanding the FLV Compression Issue

FLV (Flash Video) files have been widely used for web-based video playback due to their small file size and efficient compression. However, as technology advances, some video codecs used in FLV files may no longer be supported by modern video software, including Adobe Media Encoder. This leads to errors like “Adobe Media Encoder FLV source compression not supported” or “Adobe Media Encoder source compression type is not supported”.
