You can use the Adobe Media Encoder, which is installed with Flash Catalyst, to convert MP3 files to FLV or F4V. The help for Adobe Media Encoder is here: http://help.adobe.com/en_US/mediaencoder/cs/using/index.html.
Thank you for pointing that out, I will add a link in Flash Catalyst's help to highlight this. Feel free to comment directly on pages of help whenever you find information unclear, your feedback helps us constantly improve our learning content. Thanks for posting!
Ah - I thought of that last night in bed, but too late!
Thanks for the feedback!
So finally back to trying this out…
Okay, so this works - sort of.
The video interface is not ideal for just sound. For starters you get the video window. You can crop that out, but not neatly (i.e. the same frame all around in “wireframe” controls). Plus the full screen button is still there.
Don’t suppose there’s a way to make it realize there is no video, only sound.
Also, try as I might my 1.2 meg mp3 turns into a 2.3 meg FL4 file.
