# Connect Threads to YouTube

> Connect your Threads account as the source and your YouTube channel as a destination in Post Once. From then on, the short and long videos you post on Threads go to YouTube on their own, with your caption. Photos, carousels and text posts skip YouTube, because YouTube only takes videos.

## Before you start

- A Threads account. It does not need to be a professional account.
- A YouTube channel on the Google account you sign in with.
- A Post Once account. The free plan includes 10 reposts, with no card needed.

## How to connect Threads to YouTube

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 **Threads** and press **Continue**.

   (Screenshot: Threads picked under Where do you post first? in Post Once)

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

5. Press **Connect** on the YouTube row. Sign in with the Google account that owns your channel and allow access.
6. When both rows say **Connected**, press **Go to dashboard**.

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

## Already using Post Once?

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

If your bridge reads from another account, add a second bridge with Threads 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 Threads post becomes on YouTube

| On Threads | On YouTube |
|---|---|
| A video up to 3 minutes, vertical or square | A Short. YouTube decides this from the video, so vertical or square videos up to 3 minutes show as Shorts. |
| A video over 3 minutes, or a landscape one | A regular YouTube video, up to 2 hours and 4K. |
| A photo | Skipped, with "YouTube does not accept photos". |
| A carousel (its video slides are left out) | Skipped, with "YouTube does not accept photos". |
| A text post | Skipped. YouTube only takes 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 post text goes with each repost. When a text post has a link preview, the link's address is added to the text. Quotes, polls and GIF posts are not reposted.

YouTube fills in each upload like this:

| YouTube field | What Post Once puts there |
|---|---|
| Title | The first line of the caption, up to 100 characters. With no caption it names the source, for example "Threads video". |
| Description | The full caption, up to 5,000 characters. |
| Tags | Every hashtag in the caption, without the #. Each tag up to 30 characters, 500 characters in all. |
| Visibility | Public. |
| Made for kids | No. |

Write the first line of your caption like a title and your YouTube uploads read well too.

## Choose what goes to YouTube

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

- **What to post** has one switch here, **Videos**, since videos are all that go from Threads to YouTube. Turning it off pauses YouTube.
- **Rewrite caption** changes the caption for YouTube only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit YouTube**, 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 Threads 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 YouTube. 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 Threads to YouTube?

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 Threads posts reach YouTube?

Post Once checks Threads 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 Threads to YouTube?

Post Once uploads at most 6 videos per channel per day, to stay inside YouTube's API limits. Extra videos are not dropped: they show "Daily limit, retries in ..." and go out once the limit resets. Videos can run up to 2 hours, at up to 4K.

### Are the YouTube uploads public?

Yes. Videos are uploaded as public and marked as not made for kids.
