- Why use FLV. FLV suits old Flash-era recordings and legacy systems that ask for it.
- What you get. The FLV output uses FLV video and MP3 audio. Test the file in the older app that asks for it. The video is a black 1280 by 720 frame at 30 frames per second, with the sound from your audio file. It has no artwork, captions or waveform.
- Kvalitet. Converting MP3 to FLV compresses the sound again to fit the video, which can lower its quality a little. It never improves the sound.
- Your rights. Convert only files you own or have permission to use.
