AAC to FLV FAQs
This is a specific conversion usually required for legacy compatibility. The FLV (Flash Video) format was used by the now-discontinued Adobe Flash Player. You would only need to do this if you're working with an outdated streaming platform, an old website, or a specific piece of software that was built to only accept FLV files.
The FLV file will contain your full audio track playing alongside a simple, black video screen. Because your source file has no visual information, our converter must automatically generate this blank video stream. This is necessary to create a valid, playable FLV file that meets the format's requirements.
No, the conversion will not have any noticeable effect on your audio. The sound quality will be effectively the same as your original AAC file. The converter's primary job is to place your existing audio stream into the new FLV container, not to alter or re-process the sound itself.
The file size increases because the converter must create and add a blank video track to go along with your audio. Even a simple black video screen takes up data space. This extra data required for the video is added on top of your original audio data, making the final FLV file larger.
No, FLV is considered an obsolete format for modern web use and is not recommended. Adobe officially discontinued Flash Player, and virtually all websites have moved to the MP4 format for video. For any new project, MP4 is the universal standard and a much more compatible choice than FLV.
