Vertical or square videos up to 3 minutes can go out as Shorts. Tella uploads your video to your YouTube channel from **Share** → **Publish**, with its title, description, privacy, chapters, and your transcript as a caption track. Pick **YouTube** for a regular video or **YouTube Shorts** for a Short. ## Publish a video to YouTube 1. Click **Share** and open the **Publish** tab. 2. Under **Destinations**, pick **YouTube** (connect it first if it says **Connect**). 3. Under **Post details**, click **All destinations** to show the platform tabs, then open the **YouTube** tab and check the **Title**, **Description** and **Who can see it**: **Public**, **Unlisted** or **Private**. 4. Click **Publish to YouTube**. The progress view shows the upload and, if you chose caption tracks, **Adding subtitles**. When it's done, the YouTube row reads **Published**. After you return to the form or reopen the dialog once publishing has finished, the form shows **Published to YouTube**. Click **View** to open the video on YouTube. ## Add chapters to the YouTube description If your video has chapters, the **YouTube** tab shows **Add chapters to the description**, on by default. Tella adds the chapter list below your description, timed to the video it uploads, so YouTube shows them as chapters on the progress bar. YouTube only shows chapters when there are at least 3, the first starts at 0:00, and each is at least 10 seconds long. If yours don't fit that, the option is greyed out and says why. Edit them in the editor's **Chapters** tab. The option is only on the **YouTube** tab. **YouTube Shorts** doesn't offer it. Tella removes `<` and `>` from YouTube descriptions and cuts the text to YouTube's 5,000-byte limit. Some characters use more than one byte, so descriptions in languages such as Chinese or Japanese can be cut well before 5,000 characters. When adding chapters, Tella budgets space in characters, not bytes. A long description with multibyte characters can still have its chapter list cut off. Keep your description and chapter titles short, then check the published description on YouTube. ## Upload your transcript as YouTube captions **Publish subtitles file** under **Export settings** is on by default. YouTube gets your transcript as captions that viewers can turn on and off. If the video has translated subtitles, **Publish subtitles file** becomes **Subtitle tracks**: choose **Original** and any of the translations, and YouTube gets a caption track for each, so viewers can pick their language. All of them are chosen until you change it. If you turn on **Burn subtitles into the video** instead, Tella doesn't upload a caption track, so viewers don't get the subtitles twice. If YouTube refuses the captions, the video is still published. The progress view reads **Published without subtitles.** followed by YouTube's reason. After you return to the form or reopen the dialog once publishing has finished, the form shows **Published to YouTube with subtitles missing.** followed by the same reason. ## Tag a channel in the description On the **YouTube** tab, type `@` and the start of a channel's handle in the **Description**, then pick the channel from the list. ## Publish a YouTube Short Pick **YouTube Shorts** under **Destinations**. The video has to be vertical or square and at most 3 minutes long. Otherwise **YouTube Shorts** is greyed out and says **Unavailable: landscape video** or **Unavailable: longer than 3 mins** when you hover it. If it's landscape, change the video's format in the editor first. YouTube decides what counts as a Short from the video's shape and length, so the same rules apply whichever you pick. **YouTube Shorts** just stops Tella from uploading a video that wouldn't become one. ## Why is my YouTube video limited to 15 minutes? YouTube lets channels that aren't verified upload videos up to 15 minutes long. Tella reads your channel's limit, and for a longer video greys out **YouTube** with **Unavailable: longer than 15 mins**. Verify your channel in YouTube Studio to upload longer videos, then publish again. ## Tella's access to your YouTube account has expired Google sometimes stops renewing Tella's access. When that happens, **YouTube** asks you to **Connect** again in the **Publish** tab, and in **Settings** → **Connections** the account reads **Needs reconnecting**. To fix it: 1. Go to [myaccount.google.com/permissions](https://myaccount.google.com/permissions) and remove Tella. 2. Reconnect YouTube in Tella under **Settings** → **Connections**, or from **Destinations** in the **Publish** tab. In **Settings** → **Connections**, **Reconnect** first asks you to remove Tella at Google: click **I've removed it, reconnect**. ## Related topics - [Copy chapters for YouTube](/docs/help/export-videos/youtube-chapters.md) - [Publish Tella videos to YouTube with an agent skill](/docs/help/integrations/tella-to-youtube-agent-skill.md) - [Video requirements for each social platform](/docs/help/sharing/social-publishing-requirements.md) - [Why did my video fail to publish?](/docs/help/sharing/social-publishing-failed.md) - [Use agent skills with Tella MCP](/docs/help/integrations/agent-skills.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
