# Connect YouTube to Threads

> Connect your YouTube channel as the source and your Threads account as a destination in Post Once. From then on, the Shorts you upload to YouTube go to Threads on their own, with your caption. Longer videos skip Threads, because Threads takes short vertical videos, photos and text only.

## Before you start

- A YouTube channel. Any channel you can sign in to works, monetized or not.
- A Threads account. It does not need to be a professional account.
- A Post Once account. The free plan includes 10 reposts, with no card needed.

## How to connect YouTube to Threads

1. Create a free account at [app.postonce.com](https://app.postonce.com/signup). After two short intro screens, Post Once asks where you post.
2. Under **Where do you post first?**, pick **YouTube** and press **Continue**.

3. Under **Where else should it land?**, pick **Threads**. Add any other apps, or a backup, then press **Continue**.
4. On **Connect your accounts.**, press **Connect** on the YouTube row. Sign in with the Google account that owns your channel and allow access.

5. Press **Connect** on the Threads row. Sign in on the Threads page that opens and allow access.
6. When both rows say **Connected**, press **Go to dashboard**.

From then on, keep posting on YouTube as usual. Post Once checks it about every five minutes and reposts each new post to Threads.

## Already using Post Once?

If YouTube is already the source of your bridge, open **Bridge** and press **Connect** next to Threads in the **Destinations** card, or press **Add destination** on the dashboard.

If your bridge reads from another account, add a second bridge with YouTube as its source from the bridge switcher. Free and Solo include 1 bridge, Studio 3 and Agency as many as you need. See [bridges](https://postonce.com/help/bridges).

## What each YouTube post becomes on Threads

| On YouTube | On Threads |
|---|---|
| A Short | A video post. |
| A video over 3 minutes, or a landscape one | Skipped, with "Threads only takes short vertical videos". |

A skipped post shows the reason on your dashboard and still goes to your other destinations. See [long videos](https://postonce.com/help/long-videos) for how Post Once tells short from long.

## How your caption carries over

The video's description becomes the caption. A video with no description uses its title instead. Private and unlisted videos are not picked up, and neither are community posts.

Threads allows 500 characters. A longer caption on a photo or video is cut at 500, sometimes mid-word, so put what matters first.

## Choose what goes to Threads

On the **Bridge** page, the Threads row has two settings.

- **What to post** has one switch here, **Videos**, since videos are all that go from YouTube to Threads. Turning it off pauses Threads.
- **Rewrite caption** changes the caption for Threads only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit Threads**, and **Add your own text** at the start or end. Each one is off until you turn it on.

## Check that it works

Post something on YouTube as usual. Within about five minutes it shows up under **Your posts** on the dashboard (press **Check now** to look straight away), then goes to Threads. Each post shows where it went, what was skipped and why.

If a repost fails, Post Once tries again up to 5 times over about half an hour. If it still fails, you get an email, and **Retry** sends it again to just the accounts it missed. See [a post did not repost](https://postonce.com/help/post-not-reposted).

Only posts published after you connect are reposted on their own. Older ones are listed in [Your posts](https://postonce.com/help/your-posts), where you can send any of them by hand.

## Frequently asked questions

### Is it free to repost YouTube to Threads?

Every account gets 10 free reposts, with no card and no watermark. One repost is one post sent to all your destinations, so it counts once however many apps it goes to. After that, paid plans start at $9 a month. See [pricing](https://postonce.com/pricing).

### How fast do YouTube posts reach Threads?

Post Once checks YouTube about every five minutes, then reposts straight away. Long videos take a few more minutes to fetch and upload.

### What are the limits of reposting from YouTube to Threads?

Post Once sends at most 250 posts per Threads account per day. Threads only takes vertical or square videos up to 3 minutes.

### Why was my 4K video reposted at 1080p?

Post Once takes the best version that every destination accepts, and that tops out at 1080p. A 4K upload is reposted at 1080p.

### My caption was cut off on Threads. Why?

Threads allows 500 characters. Post Once keeps the first 500 characters of a longer caption, and the cut can land mid-word. Put the important part at the start of your caption.
