Using the computer screen recording tool can help us record the computer screen easily. Sometimes we not only need to record the picture on the computer, but also need to record the sound while recording the picture. Do you know how to record computer screen and sound? How to record the internal sound of the computer or the external sound of the computer when recording the screen?
Now the editor will share with you 3 practical methods, friends in need can read the following carefully!
1. Why there is no sound when recording the screen
Use the recording tool to record the computer screen, and the recorded video only has the picture but no sound. If this happens, it may be that you did not make the following settings before recording: When recording the computer screen, you can control the recorded sound by turning on the speaker or microphone. (If you want to record internal sound, you need to turn on the speaker; if you want to record external sound, you need to turn on the microphone; if you want to record internal sound and external sound at the same time, you need to turn on both the speaker and the microphone.)
2. How to record video with sound
So how to record computer screen and sound? The following editor takes three commonly used screen recording tools as examples to teach you how to record a video with sound and picture synchronization.
Method 1: Record video with sound using Xbox Game Bar
Step 1. Use the hotkey "Win+G" to open the Xbox Game Bar.
Step 2. Click [Audio] to open the [Audio] page, where you can adjust the internal sound of the computer, and then click the [Start Recording] button to record. (You can also turn on the microphone when you need to record external sound)
Reminder: Because the Xbox Game Bar cannot record the desktop, before opening the Xbox Game Bar, first open the page that needs to be recorded. In addition, the video file recorded by this function will be too large. If you need to record for a long time, it is recommended to use other methods recommended below.
Method 2: Use QQ screen recorder to record video with sound
Step 1. Log in to QQ, use the hotkey "Ctrl+Alt+S" to open QQ screen recording.
