Here is an example (a short film on youtube being played on my 1920x1200 monitor)

http://imgur.com/a/YTyB6

The first screen is full window (full screen browser) capture preview

The second screen is cropped to 200\200 -top\bottom

However, as you can see I still get for some reason blackness at the bottom and it gets recorded.


Any ideas?

PS I wish I could just select a part of the screen I want to record like in bandicam..Is it possible?

what resolution is your input and output. Since you have a 16:10 monitor instead of the 16:9 standard then you will get some distortion if scaling from 16:10 to 16:9. And the short film is probably 21:9

Set your canvas resolution to the right aspect ratio (assuming it is 21:9) set it to 1920x822 (or 1920x823)

Your output resolution is just scaling afterwards so it had no effect on the preview window. Even if it is scaling to a different aspect ratio.

You can manually drag and resize the sources on the preview window and use transform (right click on preview and go to transform) The edit transform lets you crop, position, rotate, align, etc. Very useful.

OBS is not as easy to setup as other programs some just allow you to select part of your screen and record in that resolution. OBS you will have to setup your canvas and output resolutions to do that. Or as I and many other people do, crop the video in editing.

If you mess up you can always hit the reset transform.

I still can't get how do I record it properly..I understand all other OBS settings, especially encoding settings, but this aspect totally eludes me.

Can someone with 16:10 monitor guide me step by step what should i chose in my settings to, say, record this https://www.youtube.com/watch?v=IP8psM4LWXk at 1280x720 without any black bars?

Your help would be much appreciated.

Alpinlol is right, either you have the footage in 16:9/16:10 with black bars, you keep it in 21:9 (which will have bars while viewing on a display that is not 21:9), you stretch video from 21:9 to 16:9 which causes distortion, or you can crop the sides of the video.

To crop the video the resolution would be a weird 1463x823. You can set this as your canvas resolution and then transform->center to screen. Probably would work. I would recommend scaling to 720p (1280x720) because 1463x823 is awkward. But then you would have much less visibility because you know your cropping out like 25% of the screen.
