You can do something else while the app is recording a screen but the
result contains black part when window is resized or the target area
won’t fit the frame.
The test steps –
OBS Studio 32.0.1
On: Windows 11 Home
Download from
https://obsproject.com/download
1. Go to the link
above to download a file.
Open the downloaded
file.
The dialog ‘User
Account Control’ shows, click ‘Yes’
Follow the on-screen
window to install the app.
When it’s done,
click ‘Finish’.
2. OBS Studio opens.
I chose ‘Optimize
just for recording….’ by clicking in front of the line, the blue
circle will be placed.
The next window
shows.
You can see the
options I chose in the picture above.
The final result
shows, click ‘Apply Settings’.
The picture above is
the target window. Video and audio playing with the app called ‘VLC’.
3. The main window
shows.
At section ‘Source’,
click +.
Select ‘Window
Capture’.
The new window
shows, click ‘OK’.
The next window
shows, I selected ‘VLC…’ in the list of windows. And I checked
‘Capture Audio (BETA) then click 'OK'.
In the picture
above, you can see the frame and the target window. You can resize or
move the target window.
At ‘Control’
section, I clicked ‘Start Recording’.
The button will be
changed to ‘Stop Recording’.
The result is, this
app can not recording video playing in ‘VLC’ player.
But it can record
audio coming from ‘VLC’ player.
In the picture above
is properties of the output video, you can see the audio and video
info.
When I resized the
target window while recording, there is no issue.
I moved the target
window while recording but the video in the output file was not
moved.
I made the target
window a background window while recording but the video in the
output file, the target window did not stay in the background.
4. I changed target
window to Firefox browser. There was no issue, it could record audio
and video playing in the browser.
When I resized the
target window while recording, the background window did not show in
the video in the output file.
I don’t like the
black part in the output file, I remember version of this app on
macOS, there is no black part if I don’t resize the target window.
