We have no details that can give us a clue. Where did the video come from? Does it open fine in Adobe Premiere or preview fine in Adobe Media Encoder? If it does, transcode the shot to a frame based production codec and use the default audio for video setting of 48 Khz 16 bit stereo.
The videos come from my Camcorder and in MTS format.
Yes. It opens fine in Premiere and other places. Even in After Effects, It imports all fine in the Project. The green waving audio sign is there to see and all fine. But as soon as I import it to the Composition, only half od the audio gets importet.
Well, like I said, EVERYTHING is 100% the same amoung all these 8 videos. They were shot at the same day, same everything. All the other 7 work just they way they should. Its just THIS one with this issue.
I just even un-installed the AE and re-installed it but still the same. New project, new composition, .. THIS video gets only half audio when in Composition.
If it works in Premiere then transcode the video to a reasonable DI (digital intermediate) format. You should also be using the MTS importer that your camera manufacturer supplies. MTS files are notorious for sound problems.
I converted the video from MTS to AVI mit MPG4 Codec and it works fine now.
Still, I don't understand how come the other very same 7 MTS videos work but not this one.
Thanks again for making me do the convert:) From now on, i will convert the videos before even starting AE
