Then it will convert SWF to MP4 and you can let it shut down computer or open output folder when the conversion is completed.

Choose MP4 as your target format and click on RUN icon to start converting. When set to 1x, the volume will not change. Click on + Video icon to upload your SWF files. Using the Volume slider you can adjust the sound level in the resulting MP3 file. Open the Video tab and pick FLV (Flash Video), select the desired preset. Select Add Video and import your files to the program. Here’s how to convert files with Movavi Video Converter. Parameters Sampling frequency and Channels (the number of audio channels in the output file) is best left in the positions Auto, then the program automatically selects the appropriate values. To convert MP4 to FLV, use special conversion software. You must remember that some older MP3 players support only MP3 files encoded at a constant bitrate, so if you want to use variable bitrate encoding, first check the documentation of your player. On the Bitrate mode list you can also set the variable bitrate encoding: ABR or VBR - Lame preset. If you set audio Bitrate in the Auto position, the program will automatically adjust the bitrate to a value close to the audio bitrate in the source file.Īt default settings will be applied encoding at a constant bitrate ( CBR). However, if you set the bitrate much higher than in the source file, the generated MP3 file will be very large, and the sound quality will be the same as using a lower bitrate. If you use a lower value, you should expect to lose sound quality. fla file is an animation project file produced by Adobe Animate (formerly known as Adobe Flash), which only contains library of objects and source files needed for creating an animation, such as graphics, video, text elements, audio, and other assets. Then in the audio settings, select the desired bitrate, which will be used to encode the audio stream from FLV file to MP3 - this parameter determines the sound quality of the resulting MP3 file.īitrate is best set to a value close to the bitrate of the audio stream in the source FLV file. If you want to set manually parameters of the FLV to MP3 conversion, you can do it in the Audio section.įirst, at the Output format list select MP3 - MPEG-1 Layer 3.
