Hi, Terra Blue.
Can you point me to these tutorials that show XFL export with audio?
It wasnt on the Adobe forums, but from lynda.com
Heres the video on youtube: http://www.youtube.com/watch?v=eiEv-ReF6NE
Note at 1:06, that is the screen I am referring to which allows you
to control whether or not to export the audio. If audio isnt
supported then why would that check box be there?
at 2:29 is when the exported xfl file is previewed in Flash, and
audio is present
Thanks for your response
What you see at 1:06 is that when you export a XFL file from an AE Comp that has video, it will take you to the Adobe Media Encoder dialog to set encoding options for the FLV file that's going to be used for exchange. The audio tab is there in Adobe Media Encoder because, of course, the FLV format supports audio. But note that it's disabled by default when you get there from the Export XFL file command.
That said, I am far from an expert in this particular area, so I am dobule checking everything and trying to learn more. I'll let you know if I find out something different.
Ok, I discussed this topic with an After Effects QE engineer who oversees the XFL feature. And I believe I have some juicy bits for you.
Yes, it's true. Audio is not supported in XFL export.
BUT... there is one exception.
If you have an FLV in the AE timeline that does not need to be re-rendered (see the help page for the rules on when layers are passed through or rendered), the FLV will be packaged into the XFL file without any alteration. So if audio is contained in that FLV, it will come into Flash.
So one workaround would be to put the audio into an FLV file before importing into AE. This has some limitations, though:
1. There has to be video in the file. AE will ignore layers that are audio only.
2. You can’t just turn off the video visibility icon. Same reason as above.
3. What you CAN do is lower the opacity of the video layer to zero (opacity changes don’t require that the layer be rendered), move it off the visible area in the Comp, or use an FLV where the video is empty (alpha channel in the On2 Vp6 codec) or trivially small.
Regarding the Audio tab you see in Adobe Media Encoder... You have noticed that the FLV settings accessible through the XFL export dialog allow you to enable audio. If you do this, any rendered FLV’s in the XFL package will indeed have an audio track, but it will be empty.
Hope this helps!
