You signed up for Post Beast. Now what? This guide walks you through everything from your first upload to building a steady habit of publishing your own original short-form videos. By the end, you'll understand exactly how to turn one piece of your own content into a week of ready-to-post shorts.
Before You Start: What You'll Need
To get the most out of this tutorial, have these ready:
- A long-form video you filmed yourself - A stream VOD, podcast episode, tutorial, or vlog. The longer it is, the more clips you get.
- A call to action or two - "Follow for part 2", "Full video on my channel", and so on
- A Post Beast plan - Every plan makes unlimited videos (see pricing)
Step 1: Upload Your Footage
Log into Post Beast, open Create, and pick Chop long-form into clips. Under "Your clips", choose a video from your library or upload a new one.
Two settings shape your clips:
- Clip length - "Auto-chop" cuts the video into back-to-back segments; "Random" pulls segments from anywhere. Set the minimum and maximum length in seconds.
- Background - Horizontal footage is fine. Choose Blur, Black bars, or White bars to fill the vertical 9:16 frame - see TikTok's official video specs.
Uploads stay in your Library, so you can reuse the same footage across as many batches as you like. Chop a 20-minute video into 30-second clips and you have around 40 shorts from one upload.
Filming a talking head instead? Pick Auto-edit a talking head on the same page. Upload one raw take and AI cuts the silences, ums and retakes and adds word-by-word captions. In review, tap any word to cut it or bring it back. Your first line is your hook, so nail it on camera:
- Start with a pattern interrupt: "Stop scrolling if..."
- Use specific numbers: "3 mistakes" beats "some mistakes"
- Create curiosity gaps: "Nobody talks about this, but..."
- Address pain points directly: "Struggling with [problem]?"

Step 2: Add a Call to Action (Optional)
Open "Call to action" and type your CTA - one per line, or paste a list. Select more than one and they rotate across the batch, so you can test which ask gets the most follows.
- Font - Pick a bold, readable font
- Color - Leave it on auto to contrast with your background, or choose a preset style
- Size - Adjust for readability on a phone
- Position - Drag it on the phone preview
Turn on Safe zones to see where the TikTok or Reels buttons will cover the screen, and keep your text out of them.
Step 3: Add Music (Optional)
Upload tracks you own or have licensed to Library → Audio, then pick them in the "Music" section. Background music can dramatically increase watch time.
"The right music doesn't just add energy - it signals to viewers that your content is current and worth watching."
Step 4: Generate Your Videos
Choose how many videos to make and click Generate. Post Beast renders them in the cloud, so you can close the tab and come back later. Progress updates live.
Step 5: Review and Download
Finished videos land in History and in Library → Generated. You can:
- Preview each video - Quick check before posting
- Download individually - Pick your favorites
- Download all - Get the whole batch in one ZIP file
- Delete unwanted - Remove any that don't meet your standards
Don't be too precious here. The goal is consistency, not perfection. Even "imperfect" videos can resonate if the hook lands - and you'll learn from every one. Learn more about how consistency compounds in short-form content.
Step 6: Schedule Your Posts
Open Schedule, connect your own TikTok, Instagram, Facebook, or YouTube accounts, and use Mass Schedule to spread the batch across days with a posting pattern. From History, the "Schedule" button loads a whole batch in one click.
Create a Posting Schedule
Spread your content out so you can stay consistent without burning out. A sustainable cadence beats a one-day flood. Buffer's research on posting frequency shows consistent posting beats sporadic bursts:
- Week 1: a steady daily cadence you can keep up
- Week 2: same rhythm, refined by what you learned
- Week 3: lean into the angles that resonated
- Week 4: a repeatable habit you actually enjoy
Track What Works
Create a simple spreadsheet tracking:
- Which opening line or clip
- Which base video
- Views after 24 hours
- Engagement rate
After a few weeks of posting, you'll have clear data on which hooks and formats resonate with your audience. Learn how to do this systematically with our hook testing guide.
What Happens After Your First 90 Days
This is where it gets exciting. Your first 90 days of consistent posting teach you more about your audience than months of guessing ever could.
You'll discover:
- Which hooks consistently stop the scroll
- What video styles get the best retention
- Which topics your audience actually cares about
- The best times to post for your niche
Use these insights for your next batch. Double down on winners. Drop the losers. Each round of content gets more effective than the last.
Common Mistakes to Avoid
Mistake #1: Waiting for Perfect
Your first batch won't be perfect. That's fine. The data you gather is more valuable than any single video.
Mistake #2: Every Video Opens the Same Way
If every video starts the same way, you're not really testing. Mix up your opening lines and first shots - different formats, different tones, different angles.
Mistake #3: Ignoring the Data
Don't just post and forget. Check performance after 24-48 hours. The numbers tell you what to do next.
Mistake #4: Posting Everything at Once
Flooding your profile with a whole batch in one day overwhelms your audience and burns through your content. Space it out strategically and stay consistent.
