The default move when sharing a screen recording on Slack is to upload the MP4. That's the wrong move. Here's the cleaner workflow your team will thank you for.

Why uploading the MP4 is the wrong move

  • It eats Slack storage. On free Slack plans, video uploads count against your message-history limits. Big videos disappear faster than you think.
  • It's slow. A 200 MB MP4 takes time to upload, blocks your Slack client, and forces every viewer to download before they can watch.
  • It's a worse experience. Slack's inline video player is fine but it's not designed for long-form screen recordings.
  • It's hard to share again later. The video is buried in a thread on a single channel. Anyone outside that thread has to be re-uploaded to.

Use a screen recorder that gives you a hosted link, then paste the link into Slack. Slack will unfurl the link into a preview card, viewers click and play in their browser, and the recording lives outside Slack's storage.

Clipy is built around this exact flow. Record, stop, link is on your clipboard, paste it in Slack, done.

Step-by-step: the Clipy + Slack workflow

  1. Open clipy.online (or the desktop app if you want system-audio capture).
  2. Click record. Pick a tab, a window, or the whole screen.
  3. Stop. The link is on your clipboard automatically.
  4. Paste into Slack. The message looks like a normal link.
  5. Slack unfurls it into a preview card with a thumbnail and the recording's title.
  6. Your teammate clicks. The video plays in a new tab in their browser.

What the Slack preview looks like

When you paste a clipy.online link, Slack reads the page's Open Graph tags and renders a preview card showing:

  • Thumbnail (auto-generated from the recording).
  • Title.
  • Source (clipy.online).

The card is clickable. Clicking opens the recording's page in a new tab. There's no sign-up gate; the link is unlisted by default but anyone with the URL can watch.

Inline playback inside Slack

Slack's classic preview card opens the link in a new tab when clicked — that's the default for any video link. Inline playback inside the Slack message itself (the way YouTube videos sometimes play) requires a dedicated Slack app with link-unfurl scopes installed in your workspace.

For most teams the "preview card → click → play" flow is fine. It's the same flow your team already uses for every other link.

Bonus: don't lose recordings to message-history caps

If your team is on a free Slack plan, message history is bounded. Files uploaded to Slack disappear with the messages they're attached to. Hosted links don't — the recording lives at clipy.online and stays accessible long after Slack's history cap rotates the message out.

Bonus: replying with video

Async-video replies in threads are an underrated workflow. Instead of typing three paragraphs to explain a UI bug, record a 30-second clip, paste the link in the thread, move on. The recipient watches in 30 seconds, comments back. Here's the bug-report version of this idea.

Quick Slack hygiene tips

  • Always include a one-line description above the link. "Walkthrough of the new pricing page" tells viewers what they're about to watch.
  • Use the channel topic or pinned posts for recurring recordings (weekly updates, demo days).
  • Don't reply with a video for a yes/no question. Async video is for things text can't compress.

Bottom line

Don't upload MP4s to Slack. Record once, get a link, paste the link. The recording lives on a real video host, the message thread stays light, your free-plan history stops disappearing, and your team can find the recording again later.
