Descript is where your team records, edits and renders podcasts and videos. FlowMattic posts the production steps to Slack: a video finished rendering, audio is mastered, a guest joined the session, a new show was set up. Editors, producers and the publishing team know what is ready without asking in a thread or opening the project.

When Descript fires Video Rendered, FlowMattic runs Send Channel Message in Slack with the data from that event.

Descript and Slack workflows you can build
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made template
Tell the team when a Descript video is rendered
A finished render is the cue for review and upload. The content channel gets the project name, so the reviewer starts watching while the editor moves to the next cut.
Audio Mastered marks a podcast episode as ready for the host platform. The publishing channel hears which episode is done, so it goes out on the planned day.
Audio Mastered→Send Channel Message
Set your Slack status while you record
When a Descript recording starts, your Slack status changes to show you are recording, so colleagues do not ping you mid-take. A second workflow on Recording Stopped clears it.
Recording Started→Set Status
Tell the producer when a guest joins the session
Remote guests join at their own pace. The producer gets a direct message as each participant arrives, so the host can start on time without watching the waiting room.
Participant Joined→Send Direct Message
Open a Slack channel for each new show
A new Descript show gets its own channel named after it, with the topic set to the show's description, so scripts, guest lists and edits for that show stay in one place.
Show Created→Text Formatter→Create Channel→Set Channel Topic
Remind the editor after a recording session ends
When a session ends, Slack sets a reminder for two days later to deliver the first cut, so raw recordings do not wait in the project for weeks.

Triggers and actions in this pair
A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Good to know
Set Status changes the status of the Slack account you connected. It suits one person recording; each host who wants it needs their own connection.
Recording Started and Recording Session Started are different Descript events: one marks each take, the other the session. Pick the one that matches how often you want Slack to change.
Slack channel names must be lower case with no spaces, so run the show name through Text Formatter before Create Channel.

Why run this pair with FlowMattic
Descript and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Production steps are visible
Renders, mastering, guests and sessions show up in Slack, so the whole team knows where each episode or video stands.
Fewer interruptions while recording
A recording status and a producer alert keep people from pinging the host at the wrong moment.
Runs on your own WordPress site
FlowMattic has no per-task pricing, so a studio rendering many cuts a day pays the same as one that renders weekly.
Common questions
How do I get a Slack message when a Descript render finishes?
Create a FlowMattic workflow with the Descript Video Rendered trigger, or Audio Rendered for audio, then add Slack's Send Channel Message. Render a test clip, map the project name into the message and switch it on.
Can my Slack status change while I record?
Yes. One workflow uses Recording Started with Set Status to show you are recording, and a second uses Recording Stopped with Set Status to clear it. It changes the status of the Slack account you connected.
What is the difference between Audio Mixed and Audio Mastered?
They are separate Descript events. Audio Mixed runs when a mix is produced, Audio Mastered when mastering is done. Most podcast teams treat Audio Mastered as ready to publish.
Can I upload the rendered file to Slack?
Slack's Upload File step can post a file when the trigger data includes a downloadable link. Check a captured Video Rendered event to see what Descript sends for your account.
