Tella posts your video straight to YouTube, YouTube Shorts, LinkedIn, X, TikTok, Instagram and Facebook: click **Share**, open the **Publish** tab, pick your platforms, and click **Publish**. Tella exports the video once and uploads it to every platform you chose, under your own accounts. ## Publish a video 1. Open the video and click **Share**. You can also open **Share** from the video's menu in your library. 2. Open the **Publish** tab. 3. Under **1. Destinations**, click each platform you want to post to. A platform you haven't connected yet says **Connect** when you hover it: click it, approve Tella in the tab that opens, and come back. See [Connect your social accounts](/docs/help/integrations/connect-social-accounts). A platform your video can't go to is greyed out: hover it to see why. 4. Under **2. Post details**, write the **Title** and **Description**. They start as the video's own title and description. 5. Under **3. Export settings**, choose the size, frame rate, speed and subtitles of the video that gets uploaded. 6. Click **Publish to YouTube** (or **Publish to 3 platforms**, and so on). The button reads **Preparing video…** while Tella exports the video, then **Publishing…** while it hands the video to each platform. A line for each platform shows **Publishing to YouTube…**, then **Published to YouTube** with a **View** button that opens the post. ## Preview your post before publishing The right half of the **Publish** tab shows a **Preview** of the post on each platform you picked, with a tab for each one. It uses the text you wrote for that platform and the name of the account you're posting as. * **TikTok**, **YouTube Shorts**, **Instagram Reels**, **Instagram Stories** and **Facebook Stories** show on a phone screen, under the buttons and captions the app draws over the video, so you can check nothing important is covered. Hover the preview to fade them out. A vertical video on **LinkedIn** shows this way too. * **YouTube**, **X**, **LinkedIn**, **Instagram** and **Facebook** posts show as they appear in a feed. The preview is hidden when the Tella window is narrow. Keep the dialog open until the button stops saying **Preparing video…**. Once the upload has started, you can close the dialog: publishing carries on and Tella records whether it succeeded or failed automatically. Open **Share** → **Publish** again to see the result. ## Which platforms can I publish to? | Pick this | To post | | - | - | | **YouTube** | A video on your YouTube channel | | **YouTube Shorts** | A Short on your YouTube channel | | **LinkedIn** | A video post on your LinkedIn profile | | **X** | A video post on your X account | | **TikTok** | A video on your TikTok account | | **Instagram** | A video post on your Instagram professional account | | **Instagram Reels** | A reel, including trial reels | | **Instagram Stories** | A story on your Instagram account | | **Facebook** | A video post on a Facebook Page you manage | | **Facebook Stories** | A story on a Facebook Page you manage | Each platform has its own length, shape and file size limits. Tella checks them before it exports anything: a platform your video breaks a limit for is greyed out under **Destinations**, and hovering it says why, for example **Unavailable: landscape video**. See [Video requirements for each social platform](/docs/help/sharing/social-publishing-requirements). ## Use different text on each platform The **All destinations** tab under **Post details** holds the title and description every platform gets. The platforms' own tabs are tucked behind it: click **All destinations** to fan them out, then open a platform's tab and edit its fields there. The rest keep following **All destinations**. Click **All destinations** again to tuck the platform tabs away. Click the reset arrow in a field's corner to go back to the shared text. A platform's tab is also where you: * Tag accounts: type `@` in the description on **X** to tag an account, or on **YouTube** to tag a channel by its handle. LinkedIn doesn't let apps tag people or Pages, so `@` stays plain text there. * Choose **Who can see it**, on platforms that offer more than one audience. Tella starts every platform on its most public option, so check this before you publish. * Set the options only one platform has, like YouTube chapters, Instagram trial reels, or TikTok's posting form. Stories don't show a title or description. On **Instagram Stories** and **Facebook Stories**, the text only names the publication inside Tella. ## Subtitles on social posts Turn on **Burn subtitles into the video** under **Export settings** to draw the subtitles into the video on every platform. YouTube and YouTube Shorts can also take the transcript as a separate caption track that viewers turn on and off: **Publish subtitles file** is on by default when you publish to YouTube. The other platforms don't take a caption track, so burn subtitles in if you want them there. If the video has [translated subtitles](/docs/help/editing/translate-subtitles), you can choose which language to burn in under **Subtitle language**, and which tracks YouTube gets under **Subtitle tracks**: **Original** (your transcript) and each translation. Every track is chosen until you change it. ## Publish the same video again Once a publish has finished, the button reads **Publish again to YouTube**. Publishing again creates a second post: Tella doesn't edit or delete the first one. If a publish fails, the platform's line reads **Couldn't publish to YouTube. Try again.** Fix what the message says and click **Publish** again. See [Why did my video fail to publish?](/docs/help/sharing/social-publishing-failed). ## Who can publish a video? Anyone who can edit the video. The post goes to the social account that the person publishing has connected, not to the video owner's account. Viewers don't see the **Publish** tab. Publishing doesn't send the export email you get from **Download**. ## Publish from an AI agent or the API Your AI assistant can publish too, through the Tella MCP server or the public API. See [Publish to social media with the API or MCP](/docs/help/integrations/publish-with-the-api-and-mcp). ## Related topics - [Publish a video to social media](/docs/api-reference/videos/publish-a-video-to-social-media.md) - [Publish to social media with the API or MCP](/docs/help/integrations/publish-with-the-api-and-mcp.md) - [Social publishing](/docs/mcp-tools/social-publishing.md) - [Integrations](/docs/help/integrations/overview.md) - [List social publications](/docs/api-reference/videos/list-social-publications.md)
