are you capturing with usb or firewire?

FYI - Firewire is a better choice

If the above doesn't apply:

when you import the video onto your timeline do you see an audio track and just not hear it - this could be a sound card setting

If you see nothing and are using firewire - which you can verify is reliable, more than likely it is a codec issue.

before you try my suggestion below you may try capturing using windows movie maker - just to see if it experiences the same problem. If it has no problems then just import the windows capture into VMS.

You can download a free program called gspot that will tell you what codec your video is using and then you can go to codec-download.com or a similar place and download the appropriate codec. install it onto your computer and then all should be well - hopefully.

good luck with it

I have the exact same issue using the Panasonic PV-GS300. I am using a USB cable, not firewire. Using Sony Video Capture from Vegas Movie Studio, I get video with no sound (nothing on the audio track.) I can however hear the audio when I play back within the "Print to Tape" window within capture. Yet when I import into Vegas Movie Studio, or even play the .avi file with Windows media player, I get no sound.

I can use Windows Movie Maker to capture, and successfully get audio, but it provides a file that plays back in 4x3 aspect ratio instead of 16x9 as recorded.

Why can't I capture audio when using Sony Video Capture?

squirrel49, does your computer have a Firewire/1394 port? If so, use it to capture the video. USB is meant to download pictures, not video from the cam. If you don't have a firewire card and have an open slot, get one, they're cheap.

Firewire capture works great on my GS-250 with 16:9.

In VideoCapture, use scene detection to capture smaller AVI files (clips) based on date/time code rather than one HUGE avi file.

Msmart,

Yes I have a firewire port, just not a firewire cable (the camcorder came with the USB cable). I'll get one and try via Firewire in lieu of USB. Note that using the same USB connection to my camcorder, I can capture both video and audio via Windows Movie Maker. This seems to indicate that the problem is with either the Sony Capture Program or one of the software settings.

I don't know if it's a problem or "by design". I know my other editing software doesn't capture USB, so I never questioned it here.

Your cam didn't come with a firewire cable? My GS250 did, oh well. Yes, I recommend getting one but don't let them make you buy the most expensive one, a simple 3 foot fw cable should do.

Check out this thread discussing firewire vs usb capture:

The audio is indeed in the files you captured, but the avi file isn't saving the audio in the format Vegas Movie Studio requires.

There are two kinds of DV avi files: Type-1 and Type-2. Vegas and Vegas Movie Studio only work (correctly) with Type-2 files, which repackages the received audio into a separate stream (within the avi file) that makes it easier and faster to edit.

Windows Movie Maker captures in Type-1 format. So when you capture a file via USB with Movie Maker, then send it to Vegas or VMS, Vegas/VMS cannot find the audio data where it expects it.

If you have already captured a lot of files, I think there are programs that can convert Type-1 to Type-2. I don't know if there is an option in Movie Maker to save as Type-2? (I've never used Windows Movie Maker...)

If you capture with Firewire using the VMS capture program, you shouldn't have any trouble.

MSMART & Timl,

Thanks for the advice. I now have a firewire cable and all is well. Audio & Video capture works fine through Sony Video Capture.

This may seem like a redundant question, but I've got a PV GS550 and I've heard of issues with using Firewire, mainly with a hot connection to the camera. Has anyone had this issue? I'd hate to fry my port; besides I dont have a Firewire port on my Dimension. I have been using the USB 2.0 cable that came with the cam to capture video and like squirrel49, can load the video to the timeline but no audio. Funny thing is I videoed with a PV GS300 and it seemed to work fine! There was an older video captured by another cam on the same tape, but would this matter? I'm a total newbie to video, so please understand. Thanks for any help!

Assuming you've got a spare slot on your motherboard, adding a firewire card shouldn't be a problem. There was some discussion about the possibility of frying a firewire port in this thread.
