If you've created home videos with your iPhone but are having a hard time finding music to accompany them, YouTube Producer has come to the rescue! YouTube Producer offers tens of thousands of copyright-free music tracks that you can add background, ambiance, and mood to your personal productions.
Copyright-free is the key point here. Most of us have big music libraries we'd like to use, but the songs they're filled with are copyrighted. If we add them to our videos, we could get complaints, and YouTube could remove the videos. Using YouTube Producer alleviates this concern completely. It has a great selection of music that can be sorted by genre, mood or tempo, and it's 100% safe to use.
There are some limitations, however. Namely, the music you choose for your video must be placed in the background of the entire video. Using it's music for just your intro, for example, is not an option. You do have control over volume, however -- either mix the music with the video's existing audio, or have the new music replace the audio track completely.
Also, YouTube Producer isn't a full blown video editor. If that's what you're looking for, you need to pick up a copy of Apple's iMovie instead.
If you just want to add a soundtrack or some background music to your the videos in your iPhone Camera roll and easily upload them to YouTube, then this is the app for you.
