What changes when you convert F4V to CAF
Only the soundtrack survives: the video stream is dropped, and the AAC audio inside the F4V file is re-encoded as PCM.
The size drop is dramatic because the video stream is where nearly all the data lives. A minute of F4V runs around 45 MB; the extracted CAF is roughly 17 MB per minute.
About F4V to CAF Conversion
This tool takes the audio track from inside a F4V file, a Flash MP4 container from 2007, and saves it on its own as CAF. Everything visual is left behind.
F4V comes from Adobe and dates to 2007. It carries H.264, which is what determines the quality ceiling of anything you convert out of it.
CAF was introduced by Apple in 2005. It carries PCM, ALAC, AAC, Opus and has native playback on 2 of six platform categories, which is the practical reason to choose it as a target.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
