I'm trying to convert .mts files to .f4v or some other working format in AME but AME shows that there is No Audio in the source as below.
When I click the encode button, true enough, the output file doesn't have any audio in them.
I'm 100% sure my .mts files have audio in them, I can hear them pretty loudly when played in VLC.
Any idea why and how to resolve this? Thank you.
Hmmm, the file header might be corrupted.
Might also be Metadata. Try the following:
- Edit menu -> Preferences... -> Metadata
- Uncheck "Write XMP ID to Files on Import"
- Source Metadata -> Preservation Rules: Exclude All
Let us know if it works.
Also, do you know what encoded this file?
Thanks for the reply but it didn't work. I have no idea what encoded this file, it might be a direct recording from the the camera itself.
I got it off from a client who has these raw footages in .mts and wanted to import them into AE CS6. I know there are some issues with .mts audio in AE CS6, I ran into them, so I was hoping to batch convert these .mts into something workable.
Thank you for the idea. Will it help if i upload the file for you to try out? Any other solutions?
I am having a similar problem. If I export a timeline fom premiere pro using media encoder the output file has audio. If I feed the same clip I used in premiere directly into media encoder it has no audio.
I've tried every setting I can and have disabled the metadata output but nothing works. I believe media encoder is failing to conform the audio. Does anyone have any suggestions? I cannot believe that there's not a solution for this yet! Common adobe fix this!!!!!
Exactly what type of clip is it? Is it muxed or demuxed? Please provide a test clip and specify your exact export settings so that we can try to reproduce the issue.
Also, let me note that in your lament that we haven't fixed "this" yet, you're making two assumptions that are far from substantiated:
This footage was shot using a Sony NX5. It is AVCHD muxed .MTS. It's faily large, over 300MB, but theres a link to it here: www.orderlockwood.com/AMEaudio.zip.
I've been doing further testing and I'm having a hard time replicating this problem. I've tried recording clips in the camera and encoding them, and they all seem to work. It appears that there is something peculiar with this batch of files, which were all shot on one SD card. Footage from the second day of shooting is all fine.
All of the clips in question will not export audio from AME CS6 on both of my computers. They will export audio through Premiere Pro, and through AME CS5 on a third computer. I do not recall if the audio format for this clip was Dolby or LPCM, but I wonder if that could play a part.
What could cause something like this? A bad SD card? A setting on the camera? Can you elaborate as to why it would work when exported from Premiere and AME CS5 but not CS6? Thanks for your help!
When I import the clip you posted directly into AME 6.0.0 (as well as a more recent build), the Export Setting dialog shows that it has audio--as you can see in the screenshot below--and the resulting output clip also has audio.
What format & preset are you encoding to?
By the way, according to MediaInfo, the audio format in the source clip is AC-3, constant bitrate of 256 Kbps, 48KHz stereo, 16 bit
I can't begin to speculate on why you're having this problem with a particular set of clips, particularly given that you have no such issue with the same content in CS5 and I have no issue in CS6. The closest thing I have to a hypothesis is that in CS6 you inadvertently encoded to a demuxed format/preset and then opened only the video component of the resulting output--but that's obviously wild speculation and not meant to impugn your video chops in any way.
Again, what app or player are you using to check whether the audio is present?
Hmm that's odd. Now I'm really baffled. On my machine it the audio track is there but it is totally silent, no waveform or level.
I have confirmed the output clip has no sound by playing the output file in windows media player, VLC and importing the clip into premiere pro. I am using the ipad2 1080p preset. I can guarantee you that I did not accidentally demux and export audio was selected.
I have also tried outputting wave audio and I get the same thing. It creates the file, but there is no waveform or level, just silence.
Have you imported the clip into Premiere Pro and listened to it? Can you hear sound?
Here's a link to the file AME outputs for me: www.orderlockwood.com/AMEnoaudio.zip If you download it you will see that it has an audio track attached with no waveform or levels, it's totally silent.
I also sent your source clip to AME (CS5.5) and encoded using the Apple iPad 640x360 29.97 preset. The encoded output file has audio in Pr, VLC and WMP.
I'll check your output file soon.
Your output file is as you described. I have no idea how you got it into that state. The most likely culprit is an audio or video codec that is interfering with the AME. It's also possible you have audio drivers or Operating System settings that are interfering at some level.
Do you have any codec packs installed?
I do not have any codec packs installed. I even uninstalled all Adobe products on my computer, ran the Adobe cleaner tool, and re-installed Premiere while testing this issue.
My guess is that it will work for you in CS5.5, I know it works in CS5.
What has me stuck is that other clips from my NX5 with the same settings work just fine. If it was a CODEC issue or audio drivers wouldn't one expect that it should never work? I can do the exact same thing with a different clip and get sound.....
I too wondered about a codec pack being the fly in this ointment, but the developer whom I've been consulting says that's not at all likely.
Given that other content off the same camera has no such problem, we suspect that there's some subtle difference in that particular batch of clips. We say "subtle" because AME CS5 and PPRO CS6 are able to handle these clips without issue.
Of course, undermining our it's-the-source hypothesis is the fact that using your original source clip, I can't repro in CS6.0 or CS6.0.1, which points to something system-specific or install-specific..
One curious data point is that MediaInfo says that your silent output's audio is CBR whereas my output w/ audio is VBR. That's may well be a red herring--maybe the glitch is preventing MediaInfo from knowing whether it's constant or variable, so it guesses constant.
Can you make do by either importing this batch of funky files into PPRO and then exporting from there, or falling back to CS5 for these clips?
You might be right about conforming.
You could have corrupt conformed audio files preventing conforming again.
Please try to encode again after deleting the following folder: "%AppData%\Adobe\Common"
Make sure to backup your custom presets if you value any of them.
I duplicated the test using AME CS6. AME CS6 produces an output file with audio, just like CS5.5. I used the iPad 2 preset. The encoded file from AME has audio in VLC, WMP and Premiere Pro CS6. So it's not the source file that's the problem. FWIW I also shoot with an NX5 and I've never run into this issue.
Thanks for your input. I've tried deleting the common files but it makes no difference.
I can move on since I know this isn't happening on other machines, but I'm happy to try anything else to try to fix this... I'm baffled by this.
I have confirmed that this issue deffinately relates to conforming.
I looked into the folders containing the source clips that have been working in AME and they have a .cfa and .pek file. The source clips that have not been working do not have either file.
I have copied the "bad" clips into a new folder, renamed them, and ran them through again. The source clips have the .cfa and .pek files, and the audio is working fine.
Could it be that the database for conformed audio is messed up? Can anyone shed some light onto this?
It is not worked also to me on OS X 10.8.1. I see into Activity Monitor that AME, while encoding, uses QuickTime resources. QT now also has sound problem (VLC does not). Might be it is because QuickTime.
I'm a newby, but I think I'm having the same problem. I have a clip from a Sony RX100. The sound is there when I play the original .MTS file, but I've tried several different settings, and I get no sound when rendered by Adobe Media Encoder. CS6.01, OS10.7.4.
Have had this exact same problem for a few months.
I've tried everything to solve it, but none of them worked.
I do have audio now, how?
well.. it isn't the easiest way, by totally restore your pc/laptop to the factory settings.
1. Copy documents, videos, music, and more important files to an external hhd (or make a windows.old file)
2. Restore and set to factory settings (http://www.youtube.com/watch?v=rcQYC948AzA)
3. Install your windows version again
4. Install master collection again
Takes a couple of hours to do this but... it's worth it.
Your PC performance will increase drastically as well
Not the easiest way, I know
I had the same issue when encoding m2ts files (using Media Encoder CS6). But the issue got RESOLVED after installing the latest trial version of "Adobe Premier Pro". Now AME works fine and there is no missing audio issue. Looks like "Adobe Premier Pro" updated/installed some system files required for "Media Encoder". The nice thing is that even after uninstalling the "Premier Pro" trial version, AME still works.
Try it and see if it reolves your issue.
We fixed several Audio related issues in AME 6.0.2 patch that was released last week. Here is a list of some of the fixes:
- TS muxer outputs m4v file if audio isn't exported.
- Can't encode specific m2t source to other format
- Cannot create a custom multichannel audio export preset
- AME encodes N-channel audio into mono, stereo and 5.1ch differently than PPro
- Encoding N channel audio source to some formats fails due to incompatible audio channels
These are just some of the audio related fixes in AME 6.0.2 patch. This patch has dozens of other bug fixes
I can confirm that the latest AME version 220.127.116.11 did NOT RESOLVED the missing audio issue in my case (for m2ts file types). I updated to the latest version and were having the same issue.
But after installing the trial version of Premier Pro CS6, the issue got resolved. So, it is very clear that AME installation was missing some important files, not sure which ones!!! Adobe developers are not able to reproduce the issue just because they may be having AME and Premier Pro on the same machine.
Having the same problem, been trying to convert mts. files into some type of H.246 File and after encoding had finished I viewed it and the video looked great but no audio....
Adobe needs to fix this problem.
I have this problem with most any file I try to encode into a .flv or .mp4 - NO AUDIO!
Stop blaming all the users and their machines and fix your software.
LOL the media encoder that can't ecode anything.
I'm having the same problem with MTS files.
I have installed A52 Codec Component -- no source audio.
I installed Perian -- same.
I installed the AME 6.0.2 patch -- same.
Using a Mac 10.8.2
3.2 GHz quad-core intel xeon
32 GB ram
First i tried to convert it normally but no sound no matter what I tried. MTS file plays normally with sound in bs player or vlc BUT NOT in windows player. That means thats some kind of win7 codec problem.
After that the easiest solution would be to try on someWIN XP machine but also on internet so I used this page (clik it) where I converted and downloaded my file. It has the sound.
I am only affraid because my test file was only 63mb but when I will need the other it has 800mb so I hope they dont have size limit.
yes I know...lucky *******
I have a Mac and I had the same problem. I figured it out, with a little help from above. I found the Adobe Common File. I then went in the cache folders. I deleted all the caches from the dates that my files were originally encoded. Then, I reimported them. When they were remimported the sound showed in all my audio clips, including the short piece that had been missing. I'm going to guess that something interupted the importation of the files the first time and then since they were in the cache, reimporting them didn't solve my problem. Since they played fine in VLC, I knew it wasn't the file.
If you are using a Mac, screennamean, you will find those files here: Your mac user name, Library folder, Application Support Folder, Adobe Folder, Common Folder. In the common folder, there are two cache folders. The Media Cache file folder holds the cache for the files that you have imported into Premier Elements. Find the file that you have a problem with and delete it. I also deleted the files with the same date that were in the Media Cache file that have unintelligible names.
