can this get better?

The quality depends on the quality of the capture card mainly, but also on the quality, length, and type of your cables (you want short as possible). Recording in a different program isn't going to improve anything except maybe if it has a better compression program, it might look slightly better once compressed.

 

Well, that would decrease the quality more. It's difficult to go about getting exceptional quality while keeping low filesizes...

 

If you were to record 9 minutes or so in High Definition it could be up to 2 gigs.

 

What settings did you capture with? That looks pretty good.

 

Unless you are going to be professionally making videos, don't mind stuff like that. I can't even see what black lines you're talking about, so almost the entirety of Youtube and the Internet won't either.

 

That would be helpful. My videos come sub-par quality wise.

 

YouTube- Rather Lucky Quickscope

that and most of the other clips by me are from the exact same device.

Compression doesn't improve quality ever, it just encodes it into a .. cleverer.. format. Capture as uncompressed AVI. You should get pretty big file sizes, and if they happen to slow you down when editing, then maybe compression is a good idea, but if you can handle the file sizes theres no point.

The lines are scan lines that you tend to get when capturing. They should be removable within editing software settings when you render your finished product. They are always present in my raw captured clips but never present in rendered clips because of interlacing techniques.

 

The quality of your video is rather bad...

As above post shows you can get much better quality but you will never get true HD with an SD capture card.

Those scan lines across the video I believe are from lag from the capture card. To stop that open up task manager, right click the program process and click set priority. Try set it as high as possible. Should help the lines. Now the cables need to be short as possible, mine are quite long, like 2m or something -.- But their gold plated so it helps, yeah silver plated lowers quality of the video, gold plated costs meagerly more so I'd get some of them. Then there's the rendering. I'd look at youtube videos for good video rendering. I'm no expert but apparently the best rendering settings are normally the default..

Depending on the size of the video you should normally compress the file. My videos are normally about 30 or so mb, anything over 200mb needs to be compressed or you will be uploading a while. There's some good compression tools out there. I don't use the compression in sony vegas, I use divx compressor which works extremely well.
