I am trying to convert an AVCHD video for viewing on my iPad 3. I use Adobe Media Encoder and select the iPad 2 settings (1920x1080) and it exports the video perfect, but no audio. I have "Export Audio" checked off. I tried it with 5 other settings and it just wont include the audio. Any ideas?
What's the multiplexing setting of your preset? Check the Multiplexing tab in the Export Settings dialog and see if Multiplexing is set to None. If so, your audio and video are being exported as two separate files, which would explain why there's no audio when you play back the video file.
Could you export your source using "AAC Audio" format and tell me if you hear audio in the output file?
Also, do you have a "mc_enc_aac.dll" file in the folder where Adobe Media Encoder is installed?
Yes it does export as AAC audio, and I do have that DLL file. There must be some setting I am missing when I try to export as an iPad 2 file. I made sure that Export Viodeo and Export Audio were both checked also.
Try to test whether the audio is present in the exported file but not playing back. What program are you using to play back the exported file? Try opening it in a few different players (Windows Media player, VLC, etc.) to see if any of them play back the audio.
Also, do you have Premiere installed? If so, import the exported file from AME into a Premiere project, add it to a blank sequence, then expand the audio tracks of the clip to see if a waveform is present. If you do see a waveform then the audio is there but not playing back for some reason.
Any of us here cannot reproduce this problem on our side here so far. It could be the specific file type (e.g. duration, video size, audio type, type of camcorder and etc) that may be causing this problem. If you don't mind, it would be nice if we can look into the file you are using. I sent you the private e-mail how to post the file to our FTP server. Please let me know (or simply reply to my private e-mail)
Seems random people are running in to this, so hopefully this solution will be found by whomever's looking.
If you're exporting video files from Final Cut Pro as .mov, and then trying to convert said .mov to an .mp4 using Adobe Media Encoder and are losing audio even though you're multiplexing, try this...
Make sure that you export only a 2-channel audio track from FCP. When I export from FCP, I split my audio into various tracks by default. Great for making master clips, but problematic if uploading to YouTube or doing further encoding in Adobe Media Encoder. Like YouTube, if you have more than 2 tracks of audio, Media Encoder seems to get confused and ignores all audio tracks. Combine all audio into a 2-channel stereo track and see if that solves the problem.
Regardless of editing program, see if reducing number of audio channels from source clip solves problem.
I think the problem here is that usually AVCHD files comes with two files of different format called MODD File and MOFF File. I think these two folders contains some information, such as audio. So Adobe Media Encoder might have not took that into consideration when exporting your video and is, therefore, missing the audio.
I am having the same problem. I am doing everything the same as I always do. I encode the avchd footage shot on my cameras (transfered to hard drive first) into mpeg2 or p2 so that it is easier to edit. Today, footage from my last shoot from 3 different cameras, all in AVCHD, won't encode audio when I try to convert into mpeg2 or p2 or h.264. Encoder won't even attempt to encode to MPEG2, it just errors and says audio length is 0. If I encode to P2 or h264 it encdeds video but no audio is in the output file. (I have tested with several media players and premiere) There is of course audio on my orriginal AVCHD footage that plays in premiere and windows media player. I tried ingesting in prelude but it has the same errors when it goes to media encoder. Please help ASAP, deadlines keep ticking.
I tried it on footage I have previously used Prelude and AME to convert successfully from AVCHD to MPEG2 and it is not working this time. I uninstalled the Premiere Pro Family and reinstalled. Still no help. Very frusterated wasted a whole afternoon on this.
