How to export 1920x1080 full screen video when you screen recording partial place

[Ryansmith]

Hi everyone, I have been facing this issues for a long time.

I trying to screen recording my chrome but I don't want to show the chrome web address and the chrome tab, Which is screenshot number 1 I attached below, btw I'm using window capture to record my google chrome.

Then I decided to using the crop/pad filter and adding 70 to the top but it come out with some black bar at top and bottom. Screenshot number 2 I attached below.

I found a youtube video to fixed this problem. To make the canvas full screen have to right click the canvas and choose " resize output ( source size) ". Screenshot number 3.

When I finish recording the screen, the video resolution is 1920x1008, do you guys have any ideas how can I crop the canvas and export exactly 1920x1080 resolution? I seen a lot of youtuber they can screen capturing partial place and the video is 1920x1080 , without black bar.

I tried fit to screen, stretch to screen, zoom the canvas, It either got black bar, or the quality is bad.

Thank you so much.

Can anyone help on this?

If you crop something away, you change the aspect ratio of the source, and this leads to black bars. If you want to keep the output video size, you need to crop equally from the top/bottom as well as from the right/left to keep the aspect ratio of the cropped source the same as the original size, then fit to screen. Cropping from the left or right in addition to the top will give you a black space where the image can grow into when you fit to screen.

If you want to capture Chrome fullscreen without tabs and address bar, consider using the fullscreen mode of Chrome instead of cropping. You toggle Chrome fullscreen by pressing F11 in Chrome.

Thank you so much Kaola, it's work!

But I still thinking cropping it without losing the quality, because when I crop the source it actually zoom in the scene. which make the video a little bit blur compare to original.

Btw, F11 really helps a lot!

If you crop, then fit to screen, you will always lose quality, because you zoom the source. It's as if you cut a picture from a newspaper: the cut picture is smaller than the whole newspaper. If you want to use the picture 1:1, for example as background for the thing you want to produce, the thing you want to produce cannot be larger than the cut picture. That's what the "resize output ( source size)" function is for: adapt the video size to the cropped picture.

If you must have a certain output size that is larger than the cut picture size, there is nothing else than zoom.
The only additional option is to get a bigger "newspaper" where you can cut a bigger version of the picture in the first place. The problem is, Windows doesn't allow you to make the browser window bigger than the desktop window size. (if you were, your cut inner space would be big enough for not having to zoom)

If you have a second monitor with a bigger resolution, for example 2560x1440, you can run a bigger Chrome window on it and get a bigger image cut from it. Some graphics drivers (AMD, Nvidia) have some "dynamic super resolution" function where they simulate a bigger desktop resolution for Windows and downscale internally to a smaller physical monitor. So for Windows and for every app there can be a 2560x1440 or even bigger desktop resolution but still on a 1920x1080 monitor. However, this is a quite elaborate workaround for a somewhat small issue.

While Koala was replying, I looked through my pictures for the example below. By definition it will get a bit pixelated: if you'd start with an image with 1000 pixels wide and you cut away 200 pixels, the remaining 800 pixels have to cover the same space of 1000 pixels. So every remaining pixel has to be enlarged.

This is the principle of digital zooming. The only way to avoid loosing quality while zooming is using zoom lenses (optical zooming).

If you have this concern with just your browser window: Focus the browser and press "F11".
This will hide the title, address bar, etc. and just show the website in full-screen mode. Press F11 again to exit.
