After rendering a social clip, you can publish it to your connected social accounts without leaving Mato. This guide covers the publish modal, caption editing, status tracking, and what to do when something goes wrong.
Before you start, make sure you have at least one social account connected. If you have not connected any accounts yet, go to Social Content > Settings and follow the connection flow for LinkedIn, TikTok, Instagram, or YouTube.
Open the publish modal
From the clip editor page, select the clip you want to publish in the filmstrip sidebar on the left. The clip must have a rendered video (the Publish button stays disabled until rendering is complete).
Click Publish in the header actions bar. The publish modal opens, showing your connected social accounts grouped by platform.
If you have no connected accounts, the modal shows a prompt to visit Settings and connect one.
Select accounts
Your connected social accounts appear in a scrollable list, grouped under platform headers (LinkedIn, Instagram, TikTok, YouTube). Each account shows its display name and a checkbox.
Tick the accounts you want to publish to. You can select multiple accounts across different platforms in a single publish action.
If the clip belongs to a podcast or brand that has linked social accounts, those accounts are pre-selected when the modal opens. You can uncheck them if you prefer not to post there.
LinkedIn accounts that are connected as company pages display a small "Page" label next to the account name to distinguish them from personal profiles.
Write a caption
Below the account list, a text field holds the caption that will accompany your post. Mato pre-fills this with the clip's AI-generated suggested caption when one is available, or falls back to the clip title.
Edit the caption to fit your audience. The character counter below the field shows how many characters you have used out of the 2,200 maximum.
The same caption is sent to every selected platform. If a platform has a shorter limit (TikTok titles, for example), the text is truncated on that platform's side.
Publish
Click Publish at the bottom of the modal. The button shows a spinner while Mato creates the publish jobs.
Once the jobs are queued, the modal switches to a success screen showing a green checkmark and the list of platforms you published to. Click Done to close the modal.
Publishing happens in the background. The video is uploaded to each platform through Mato's publishing pipeline, and status updates appear automatically as each post completes.
Track publish status
After publishing, status indicators appear in two places.
Filmstrip thumbnails
Each clip thumbnail in the filmstrip sidebar shows a small overlay in the top-left corner with platform icons. A spinner appears while the post is in progress. A green checkmark replaces it once all platforms report success. Hover over the overlay to see per-platform status details.
Clip details panel
The details panel on the right side of the clip editor shows a "Published to" card listing every platform the clip has been posted to. Each row shows the platform icon, platform name, and current status:
- Publishing... with a spinner means the post is still being uploaded or processed.
- Published with a green checkmark means the post is live. If a platform URL is available, a View post link appears next to it.
- Failed with a red icon means something went wrong. Hover over the status to see the error message.
Header badge
When viewing a clip that has publications, a status badge appears in the header area. The badge summarizes the overall state:
- All published: green "Published" badge with clickable platform icons that link to the live posts.
- All in progress: amber "Publishing" badge with a spinner.
- All failed: red "Failed" badge. Hover to see error details per platform.
- Mixed states: the badge shows counts like "2 published, 1 failed" and uses the most severe color (red if any failed, amber if any are still processing).
View published posts
After a clip is published, you can open the live post on each platform. There are two ways to do this:
- In the clip details panel, click View post next to the published platform row.
- In the header badge, click a platform icon when all posts show as published. Each icon links to that platform's post.
Both open the platform URL in a new browser tab.
Retry a failed publish
If publishing fails on one or more platforms, you do not need a separate retry button. Open the publish modal again for the same clip, select the accounts that failed, and click Publish. Mato automatically clears the previous failed records and creates fresh publish jobs.
The "Already published" section in the modal only shows successful or in-progress publications. Failed ones are hidden so they do not block you from retrying.
Republish to additional platforms
You can publish the same clip to more accounts at any time. Open the publish modal, select the new accounts, and publish. Accounts that already have a successful or in-progress publication for this clip are skipped automatically (the publish request is idempotent for completed posts).
Understand the publishing pipeline
When you click Publish, Mato runs the following steps in the background:
- Mato queues one publish job for each clip-and-account pair, with status set to "pending".
- The job uploads the rendered video to each selected platform through Mato's publishing service.
- After upload, the status moves to "uploading" and then "processing" while the platform ingests the video.
- Mato polls for completion. When the platform confirms the post is live, the status changes to "published" and the platform URL is saved.
- If the platform does not respond within about 90 seconds, the publication is marked as "failed" with a timeout message. You can retry at any time.
- Once at least one platform confirms success, Mato sends you an email notification with a link to the clip editor.
Limits
Each publish request supports up to 20 clips and 10 social accounts. For most workflows this is more than enough, since you typically publish one clip at a time to your connected accounts.
What is not supported yet
- Post scheduling. You cannot schedule a clip to publish at a future date or time yet. All publishes happen immediately. Scheduling is planned for a future release.
- Per-platform captions. The same caption text is sent to every selected platform. Writing different captions for LinkedIn vs. TikTok is not available.
- Bulk publish across clips. The publish modal operates on the currently active clip. To publish multiple clips, open the modal for each one individually. This is by design so you can review and caption each clip before it goes out.
