Sometimes we only focus on recording the computer screen, but ignore the sound of the recorded video, resulting in a recorded video file with only the screen and no sound. Do you know why the recorded video has no sound? How can I record a screen recording file with sound and picture synchronization? If you want to record a video with audio and video synchronization, you must first have a screen recording software that supports audio recording.
The following editor will introduce to you a screen recording file that can record sound flexibly. Come and see which one it is!
1. Why there is no sound when recording the screen
Why there is no sound when recording the screen? It may be that you did not turn on the speaker or microphone when recording the video . When recording internal sound, turn on the speaker; when recording external sound, turn on the microphone. Only in this way can the video with sound and picture synchronization be recorded.
2. How to record a video with sound and picture synchronization
The following editor will teach you to record a video with sound and picture synchronization in detail, and you need to use a professional screen recording tool. This computer screen recording tool, which I will end today, supports recording multiple sound sources. There is no need to make special settings on the computer, just click the microphone/speaker option of the software before recording, and you can record videos with different sounds. Generally, we recommend that you perform sound audition and pre-recording before recording, so as to avoid finding that the sound is wrong after recording in an emergency.
The following is the specific operation of the software:
Step 1. Obtain the software installation package from the software website. When installing, you can choose a disk other than the C drive as the installation path to avoid the C drive being full.
Step 2. After installing the screen recording software, if you are installing the software for the first time, the software will pop up the [Beginner's Guide], which is convenient for you to quickly understand the software functions.
Step 3. Click [Video Recording] on the left side of the software main interface to enter the [Video Recording] page. Click [Set Exclusion Window] on the left side of the page, and you can exclude pages that you do not want to be included. Click [Output Settings] on the right side of the page, and you can modify the parameters of the video. (The default video format is MP4; the default frame rate is 24fps; the default quality is standard quality), then select the recording range, and then click the [REC] button to modify.
