What You Need to Know
How creators crosspost Instagram Reels to YouTube Shorts today
Clean workflow: save the original video file before uploading to Instagram.
Upload that original to YouTube Shorts and add YouTube Audio Library music separately if the Reel used Instagram-licensed audio.
This avoids both the watermark and the music rights problem.
Make your Shorts look native on YouTube
YouTube Shorts has a different discovery mechanic than Instagram Reels.
Three things make a Reel perform on Shorts.
Skip the manual work with PostOnce
PostOnce automates Instagram Reels to YouTube Shorts.
When you post a Reel, PostOnce picks up the watermark-free video and uploads it to your YouTube channel as a Short, with the title and description you define.
