Questions about sharing YouTube on Instagram
Can you share YouTube Shorts on Instagram?
Yes. YouTube only offers a link, so upload the Short as a Reel yourself, or let PostOnce post each new Short to your Reels.
Is YouTube connected to Instagram?
No. Adding your YouTube link to Instagram only shows a link; it doesn't copy videos. PostOnce connects the two so your Shorts post as Reels.
How do I share a YouTube video on my Instagram Story?
Copy the video link, then add it to a Story with the link sticker. Viewers tap it to watch on YouTube.
Can I post my YouTube Shorts to my Instagram Story?
Yes. Turn on Post everything as Stories for your Instagram account and each Short goes to your Story as the video itself, instead of Reels. Videos over 60 seconds are skipped, and captions don't show on Stories.
Do long YouTube videos go to Instagram?
Only if you turn on regular videos. Reels can run up to 15 minutes, so longer uploads don't post.
Does PostOnce cut long videos into short clips?
No. It posts your videos as they are. Cutting highlights from long videos is a job for a clipping tool.
Can I upload the same Shorts on YouTube and Instagram?
Yes. PostOnce posts through Instagram's official API, like any scheduler. In a check of 40 YouTube channels before and after crossposting, YouTube views showed no consistent drop.
Do I need an Instagram Business account?
Yes, a Business or Creator account. Meta only lets apps post to those.
