Part 7: How to Upload MP3 to YouTube

What is MP3 Format?

MP3 is also known as the MPEG-1 Audio Layer. Created by the Moving Pictures Expert Group, this format uses the lossy algorithm to store and play audio clips, thereby effectively reducing the storage space needed to compile the file without affecting the quality of sound too much.

The popularity of this file format was and still is phenomenal over the internet. It is currently the format of choice as far as music files are concerned. It is also the type of file most shared over a peer-to-peer network. When the ripping of CD’s to create MP3 files became possible, many record companies claim that such an act is a copyright infringement.

An MP3 file is predominantly characterized by its bit rate. The higher the bit rate, the closer the output will be to the original sound. However, an MP3 file with a higher bit rate would also mean a bigger data file.

Upload MP3 to YouTube

Want to upload MP3 to YouTube for sharing? YouTube does allow you to upload audio or image files as long as you convert the audio and image files to the format that will work on YouTube. And you must make sure you have the copyright of the content you want to upload.

To upload MP3 to YouTube on Mac, you can use iMovie to help you to convert MP3 and an image to a .mov video file that YouTube supports. (If you are using a Windows PC, you can use Windows Live Movie Maker for help.)

  • Step 1. Launch iMovie and drag an image and the MP3 file to the project area.
  • Step 2. Adjust the duration of the image to fit the duration of the MP3 audio track so that the file can be uploaded properly. To do so, in the green box, click the gear icon > Clip Adjustments. Copy the number under Source Duration for the audio track. Mouse over the image and click the gear icon > Clip Adjustments. Then enter the number you have copied. Click Done.
  • Step 3. Click the Share button and select the option of Export using QuickTime… Give a name to your file and click Save. Then you can upload the converted MP3 to YouTube site.
