Default Issue with playing MPEG-4 audio


I'm not sure if anyone else has experienced this issue, so any help will be greatly appreciated because it is driving me nuts!

Basically, there is an issue when converting any file (mainly AVI, WMV or QT) to an MPEG4 file using the MPEG-4 option of the 'QuickTime Plugin' preset on Procoder 3.05.91. When I play the file out through any of my media players, there is no audio at all throughout the file.

Now I'm not sure whether this is a Procoder or an AAC-LC codec issue, but it seems to have happened ever since I changed over from XP 32-bit to Windows 7 64-bit. I think this may be where the problem lies, as I currently also have Procoder on a Windows 7 32-bit machine, and this problem doesn't exist.

However when I open the source file in QuickTime player and export the movie as an MPEG-4 movie, the resulting file plays with audio and is absolutely fine. It uses the same Export Settings menu as Procoder, which leaves me to believe it isn't a codec issue and is indeed a bug inside Procoder.

Either way, I'm rather baffled. Thankfully the QuickTime option allows me to convert to MPEG-4, but it would be good to to the bottom of this issue so that I can use Procoder bug-free!

I have tried unistalling and re-installing several versions of Procoder, including the latest 3.6 version, but nothing I have tried seems to make a difference...

Default MP4 Audio Problem with Procoder

I have the same issue
I am still on XP and Procoder 3. Everything has been working fine for three years. All of a sudden the MP4 files made in Procoder stopped producing an audio track. The target calls for an audio track. There is audio on the source file. Everything is the same as it has been since Procoder was installed three years ago.

The other targets all produce audio tracks. Only the MP4 target is broken. I've tried removing and reinstalling Procoder but when I do that my old custom targets are still there so I know windows is not removing everything from Procoder.

Does anyone know where the targets are stored? Maybe if I could toss those and then reinstall Procoder I would have better luck.

Are you sure QuickTime hasn't updated itself?

I'm also seeing this issue. I think it is due to a Quicktime update. I had several h.264 MP4 container encoding profiles set up in procoder that were functioning just fine. Had an Win7 64-bit editing system that hadn't been connected to the internet until just last week. I noticed a Apple software updater that popped up and it gave the option to update QT to the latest release. I chose to do so.
A day or so later I encoded some videos to h.264 MP4 using the presets and then noticed that they contained no audio track whatsoever only the video track.
I just tried another system which was Win XP 32-bit using the same encoding profile and same thing, no audio in the MP4 file. Both of these systems are using QT 7.7.1
A 3rd system running Win7 64-bit has not been updated, and is using 7.6.7. Encoding using the same H.264 mp4 profile results in audio track being included.
So it is definitely related to the QT 7.7.1 build.

QT 7.71 is faulty

you need to uninstall and install an earlier version, or wait for someone to update ProCoder to support 7.71 (maybe in your next life)

QT 7.71 will be supported in the next version of EDIUS 6.06

so it appears a permanent change has been made by apple that won't be changed back the old way, so you will always need to use an older version to get audio
