Panasonic camcorder 16:9 problem

I've got a 7 year old Panasonic DV camcorder. I always capture the footage to my PC hard disk for editing. I normally film in 4:3 mode, but I filmed some footage in 16:9 mode as well.

Now, this 16:9 footage is OK when watching it on the camcorder's LCD, it has black bars at the top and bottom. But when capturing it to my hard disk, a second pair of black bars is added to the image, vertically compressing the video and covering about 1/4 of the top and bottom of the screen with black bars. I've tried playing around with the camera's settings when capturing, tried 2 versions of Video Studio and 2 versions of Scenalyzer for capturing, nothing helps.

Anyone an idea?

I've recently run into a related issue with some footage I captured in anamorphic mode on my Cannon. Assuming your Panasonic DV camcorder is not HD, which is a pretty safe assumption since you state it is 7 years old, you are actually capturing full frame SD video. See this link for more information on anamorphic video formats

and
http://en.wikipedia.org/wiki/Anamorphic

Also, playback can control the vertical bars you are seeing. There is some good information on

For further investigation it would help if you gave the model number of your camcorder. Good luck!

Hi. I'm not sure what software you are capturing into, but you need to explicitly tell the software you are capturing 4x3 (even for 16x9 video).

When your video camera is set to 16x9 it's really recording 4x3 and putting black bars in the video.
Then if you import the video and tell your computer it's 16x9 it is stretching it out to 16x9 aspect ratio, which compresses the video vertically.
So tell the software you're in that you are using 4x3 video and then it should look proper. If you need true 16x9 then you could possibly crop out the black bars and export it as 16x9 but that's pretty advanced and most video editing software can't do that.

Hope that helps.

Thanks for the answers so far. For completeness, I am capturing in 4:3 mode and tried 16:9 as well, makes no difference.
The camera is a Panasonic NV-DS38EG.
What I suspect is that it shoots footage in 4:3 and replaces top and bottom with black bars to simulate 16:9. Then sets some kind of 16:9 flag in the output stream, which is interpreted by the capturing SW which switches a 4:3 format with black bars to a real 16:9. But that's just a guess.
