Thin distorted line at black bar borders

Hey,

New to this forum -- just registered to see if there would be any Vegas wizards here (I hope).

I'm experiencing a problem which occurs after rendering my project -- a thin distorted line at the borders of black bars. Here's a pic of it:

As you can see, those lines show up whether the image is 16:9 letter or 4:3. But when the image is fullscreen 16:9, there are no problems. Those lines also do not show up in the Vegas preview screen. I haven't had this problem before, so I'm struggling to think what I did differently, but just can't figure it out. It doubt it's render settings, since it's the same Internet 1980p I've used always before.

I tried to search through the www's but couldn't come across an answer. Do any of you guys have experience with a problem like this?

Please ask me more details if it helps.

Edit: Oh, and the thing I'm trying to render is a video essay. So basically it has clips and keyframing with png images on top and so on. And the source videos are all pretty much mp4 or images in JPG and png. But the lines appear in every clip with black bars, no matter where they are from. And I have tried nonprogressive scan.

And even if I copy the contents of this project to a different project which I have rendered properly before, this problem still persists.

More edit: Okay guys, seems upon further investigation that the problem actually isn't with Vegas rendering but with VLC. For whatever reason VLC causes these lines when I render from Vegas, but there are none with Windows Media Player. Seems there is no danger after all -- I don't need it to play in vegas, just on Youtube. But I wonder why VLC has those lines -- as they are only on files I render myself, not for example on movies downloaded from elsewhere. Maybe it just doesn't like MP4...

Anyway, this sub proved to be more useful than I thought. :)) If I seemed panicked talking to myself here, it's because I was -- deadlines and all.

Thanks very much.

When you put a movie on a larger canvas, any sharpening may show up as edge piping. That is likely what VLC is doing.

Try switching between software and hardware acceleration in VLC preferences and see if that makes a difference.
