Very Strange Black Box Issue

[Batman]

Hello, I have strange problem when i try to record in 720p . (My Screen Resolution is 1680x1050) There's a strange box around whole video... i think that after video upload to youtube, it will stretch and everything will be ok... After upload i click on 720p then fullscreen, and quality is bad, i mean it looks like 480p...

I'm confused whenever your question is about the black bars, or bitrate quality.

YouTube has very harsh bitrate restrictions on a fast motion videos. Some videos look even bad in 1080p, much less in 720p. If you want to improve the quality you should consider purchasing a 1080p monitor and recording at that resolution which will increase the bitrate limit for your videos since 720p has lower limit.

As for black bars, there are no bars in your YouTube version.

But why there's a black box when i open .AVI ?

just my few cents:

it's all about aspect ratios.
1680x1050 = 16:10
720p is usually 1280x720 = 16:9

black box is MOST LIKELY due to this, the resolutions are different shape, some blackbarring is bound to happen. if you play 16:9 video on 16:10 screen, you will get black bars on top and bottom, no way around this unless you strech the video (don't).

But why there's a black box when i open .AVI ?

As Malix previously explained it's because you own uncommon monitor which has the 16:10 Aspect Ratio. Between 2003-2008 this aspect ratio monitors indeed were very common. But ever since 2008 they were practicly replaced by 16:9 aspect ratio monitors, and the mainstream media use primarily only 16:9 aspect ratio now, including the YouTube website.

You are capturing your gameplay in 1280x720 I assume, which is 16:9 aspect ratio resolution. YouTube likes it, that's why there are no bars on it. But your monitor doesn't like it, that's why only your monitor can see those bars. If you record your video in 16:10 and upload it to YouTube then result will change, your AVI file no longer will have black bars but your YouTube video will have them.

16:9 Common Resolutions:
640×360, 854×480, 960×540, 1024×576, 1280×720, 1366×768, 1600×900, 1920×1080, 2048×1152, 2560×1440.

16:10 Common Resolutions:
1280×800, 1440×900, 1680×1050, 1920×1200, 2560×1600.
