Codec for EX3 audio in V9 64bit

Mikey QACTV7 wrote on 5/19/2009, 1:26 PM
My audio is not running correctly on timeline for direct import of the mpg4 files from the Sony EX3. Maybe a codec problem? Does anyone out there have a solution. I tried a Shark 007 codec pack but no fix. I am running the same OS on another computer Vista Ultimate 64 and the audio is fine when I import the Sony EX files. I am going crazy trying to figure this out. Maybe some one has the answer.

I don't know anything about EX3 files. But logically if these files run ok on one system then you'd have to suspect that the problem is the other system. There has to be some sort of conflict -- hardware or software. From reading your other thread, your problem is on the Dell Systems T7400. This will sound like the longest way to find the problem but it might be the shortest. I had a similar problem too long to explain and finally isolated the conflict this way --- Use a fresh harddrive on the T7400 -- load it with your OS -- Don't load anything else - NOTHING except Vegas. Try it. This will isolate the problem. If the files work you start loading up the system to its normal state, each step of the way checking Vegas. My premise is that Vegas runs fine in one environment with these files. Something is up with the other system(s).

The audio in the EX3 is only PCM, no codecs need to be added to your system, in fact I'd advise against adding more codecs unless you absolutely know you need to. You can cause 'codec chaos' and create another problem.

The EX cameras and just about every video camera uses audio at 48KHz, some sound cards do not seem to work too well at that sample rate. Also you're running Vista 64 and drivers for some sound cards under Vista 64 are at best dodgy.

1) If those Dell systems are using Sound Blaster cards get rid of them. Get something decent, you'll need at least a few edit systems with good audio monitoring.

2) I'd also suggest downgrading your OS to Vista 32 or Win XP. 64bit is still bleeding edge with a lot of things in the NLE world including Vegas and audio drivers.

Whatever your problem is, it's not Vegas alone. I and many others here regularly edit EX footage in Vegas. I've never had an audio problem with EX files.

It's true if you are using 64 bit OS then you need 64 bit codec. But -- if your system at home is running the EX files on Vista 64 with no audio problems, then it is not the OS that is the problem. Think like Spock. Logical.

I don't have an EX3 but if Vegas draws the audio waves on the timeline it is not a codec problem, it is a sound card/driver issue. May be worth tweaking the audio settings in Vegas's preferences.

If Vegas does not draw the waveforms or says there is no audio, then that is a codec problem.

I wouldn't be so certain.
I've recently had Vegas draw a waveform and produce no audio. Even more curious putting that problem clip onto the T/L caused all audio to mute but only after a few seconds.

Aside from that, agree, it's almost certainly a driver issue and Dell are pretty notorious for selling sound cards that have been striped down. That's where I'd be starting from. More to the point I think SCS could have a devil of a time tracking this down unless they have exactly identical hardware.

I found the problem. Just by chance. I wanted to get a project done and the mpeg 4 video from the camera worked ok on the time line so I deleted the audio and put some music under it. The music started to do the same as the pcm audio I was having problems with. I turned off the video track with the mpeg 4 video and the audio worked fine. I put back the audio from the mpeg 4 turned off the video track and the audio was fine. So I focused on the video as the problem. Went to NVidas website and found a new driver for the video card just released last week and presto good audio. I guess when troubleshooting always never rule out the imposible.
