How to post videos on Reddit: pro marketer guide

1. Manual ways to post videos on Reddit

Method 1: Post a native Reddit video from desktop

1. Prepare your video in MP4 or MOV under Reddit’s size limits.
2. Log in to your Reddit account.
3. Choose a relevant subreddit. Read its rules in the sidebar or under the "About" tab.
4. Click the "Create Post" button.
5. Select the "Image & Video" (or "Video") post type.
6. Drag-and-drop your video file or click to upload.
7. Add a compelling, subreddit-appropriate title.
8. Optionally add body text, timestamps, and links (respecting rules about self‑promotion).
9. Double‑check flair, NSFW, and spoiler settings if required.
10. Click "Post".

See Reddit’s official guidance on posts and media:

• Reddit video overview: https://support.reddithelp.com/hc/en-us/articles/360043043012

Pros: Full control, you read rules carefully, good for learning each community.
Cons: Very time‑consuming at scale, easy to make mistakes when rushed.

Method 2: Share a hosted video (YouTube, Vimeo, etc.)

1. Upload your video to your preferred video host.
2. Copy the public URL.
3. On Reddit, click "Create Post" in the target subreddit.
4. Choose the "Link" or "Post" type (depending on UI); paste your video URL.
5. Write a title that sets expectations ("[Guide]", "[Case Study]", etc.).
6. Add context in the text field: what viewers will learn, who it’s for.
7. Check subreddit rules on link posts and self‑promo.
8. Hit "Post" and monitor comments.

Pros: Offloads hosting, easy to reuse the same video across channels.
Cons: Some communities prefer native Reddit video; you may get less engagement.

Method 3: Cross‑post your own successful video

1. Find a video post you already published that performed well.
2. Click the "Share" or "Crosspost" option under the post.
3. Select a new subreddit where the content is relevant.
4. Adapt the title to that community’s language.
5. Review rules again; some subreddits dislike cross‑posts.
6. Post and track performance.

Pros: Uses social proof; leverages one winning video in multiple communities.
Cons: Still manual; can lead to spam reports if poorly targeted.

2. No‑code automation methods

Method 4: Use automation tools to queue uploads

You can connect Reddit to no‑code automation platforms like Zapier, Make (Integromat), or n8n (self‑hosted). While their native Reddit integrations are limited, you can:

• Trigger on new video in a storage or CMS (Google Drive, Dropbox, Airtable).
• Prepare a draft post: title, URL, subreddit name, flair.
• Send yourself a notification with a one‑click link to finalize the post.

Typical flow:

1. "New file" trigger in Google Drive or "New record" in Airtable with video metadata.
2. Automation formats a suggested Reddit title and body.
3. Automation pings you in Slack/Email with a ready‑to‑copy template.
4. You manually paste into Reddit and upload the video.

Pros: Speeds up prep work, centralizes metadata and copy.
Cons: Still requires you to click through and post; tools can’t fully operate the Reddit UI.

Method 5: Schedule content planning in a no‑code hub

Use Notion/Airtable as a Reddit video content calendar.

1. Create a table with columns: Video URL, Target subreddits, Title variants, Flair, Posting date, Performance.
2. Use no‑code tools to:
   • Pull performance stats into the table (views, upvotes, comments) via Reddit’s API or manual import.
   • Generate title suggestions using AI text tools integrated via Zapier/Make.
3. At posting time, your team uses the table as their single source of truth while manually uploading to Reddit.

Pros: Much more organized; easier to delegate posting to junior teammates.
Cons: Still human‑heavy; context switching between tools and Reddit.

3. Scaling Reddit video posting with AI computer agents

Manual and no‑code methods break down once you’re posting daily across multiple subreddits and accounts. This is where a Simular AI computer agent, powered by Sai, becomes your digital operator.

Method 6: Desktop‑level Reddit posting agent with Sai

Sai is a highly capable computer‑use agent that can automate nearly anything a human can do across your desktop and browser. Instead of APIs or brittle scripts, you:

1. Define the workflow once:
   • Open browser and log in to Reddit.
   • Navigate to specific subreddits.
   • Read or reference stored posting rules.
   • Upload video files from a folder or cloud drive.
   • Paste titles, descriptions, and tracking links from a spreadsheet.
   • Submit posts and log URLs in a central sheet.

1. Use Simular’s transparent execution to inspect every action the agent takes: clicks, text inputs, page loads.
2. Connect your content calendar (Google Sheets, Airtable) via a webhook so the agent knows which videos to post and where.

Pros:

• Production‑grade reliability for workflows with thousands of steps.
• Runs end‑to‑end like a real assistant, not just API calls.
• Fully inspectable and modifiable actions; no black‑box automation.

Cons:

• Requires initial setup and clear instructions.
• You should still review subreddit rules periodically yourself.

Method 7: Multi‑channel video syndication with one agent

You can evolve the workflow so your Simular agent doesn’t just post to Reddit:

1. Agent pulls a new video from your "ready" folder.
2. Posts to Reddit with community‑specific titles.
3. Logs the Reddit URLs.
4. Optionally posts the same video to other platforms (eBay style listing, YouTube, or others) using similar UI automation.
5. Updates your master spreadsheet with links and basic performance metrics it scrapes (upvotes, comments) from each Reddit post.

Because Simular’s agents are designed for long, multi‑app workflows and can reliably perform thousands to millions of steps, this scales far beyond what a VA or social media manager can do alone.

Pros:

• True "set once, run often" posting machine.
• Frees sales and marketing teams to focus on creative, not clicks.

Cons:

• You’ll want good governance: decide which subreddits, what cadence, and when the agent should escalate to a human.
