Audio fade-out at end is not present in converted video

Post by rsampson » Thu Jul 31, 2008 5:52 am

This may be a bug, I'm not sure.

I have a full quality quicktime animation .mov exported from After Effects, which has an audio track that fades in at start and fades out at the end. When I convert to H.264 MP4, with either FAAC or LAME, the beginning audio fades in correctly, but at the end the audio stays at a constant level (doesn't fade out). I tried the different object types for FAAC, as well as a few other options, and the problem persists.

This is very odd, anyone know what's going on here?

MediaCoder version 0.6.1 Build 4150

When you click "Play" button of your input file, does the audio fade out at the end of the video in MediaCoder?

Yes it does. It also fades out in quicktime player.

Did you uncheck the normalize box under Audio Tab?

Yes. normalize is not checked.

Options are:
source - auto select
encoder - FAAC (also tried LAME MP3)
resample - orginal
channel - original
audio ID - 1
gain - 0dB
normalize - unchecked
external file - unchecked
enable audio - checked

mpeg version - mpeg4
object type - tried them all
container - tried both AAC and MP4

Under Audio Tab, change source to either MPlayer, MEncoder or FFmpeg by unchecking auto select box.
