To add music and sound effects to a video on your computer without using any software or apps, you can try using an online video editor that provides such features. There are several web-based video editing platforms available that allow you to upload your video, add music or sound effects, and download the edited video without the need for additional software installation. Here's a general step-by-step guide:
Search for an online video editor: Look for reputable online video editing platforms that offer audio editing capabilities. Some popular options include WeVideo, Kapwing, and Clipchamp.
Upload your video: Once you've chosen a suitable online video editor, upload the video you want to edit to the platform. Most editors provide a simple drag-and-drop interface to upload files.
Import the music or sound effects: Explore the editing options provided by the platform and locate the audio import feature. Usually, you'll find a "Import Media" or "Upload Audio" button. Click on it and select the music or sound effect files you want to add to your video.
Arrange and adjust the audio: After importing the audio files, you can drag and drop them onto the video timeline or audio track. Adjust the placement and duration of the audio according to your desired timing. Many online editors also allow you to trim or adjust the volume of the audio clips.
Preview and fine-tune: Play the video to preview the changes and make any necessary adjustments. Ensure that the audio and video elements are synchronized properly.
Export and download the video: Once you're satisfied with the edits, find the export or download option within the online editor. Choose the desired video format and resolution, and initiate the export process.
Wait for the video to process: Depending on the size of your video and the processing capabilities of the online editor, it may take some time to generate the final edited video.
Download the edited video: Once the processing is complete, you should be able to download the edited video file to your computer. Follow the on-screen instructions provided by the online editor to save the video.
Remember that the availability of features and the specific steps may vary depending on the online video editor you choose. It's always a good idea to explore the editor's documentation or tutorial section if you need additional guidance.
