Dial In Encoder and Bitrate for 1080x1920

Key Takeaway: Hardware encoding with CBR ~9000 kbps delivers crisp vertical 1080p at 60 fps.

Claim: CBR at ~9000 kbps is a strong quality target for 1080x1920 60 fps vertical streams.

Choose a hardware encoder when available and match bitrate to your upload headroom. Lower bitrate if your internet can’t sustain it.

  1. In OBS, open Settings > Output.
  2. Select a hardware encoder: Apple VT on Mac, NVENC on Windows if available; x264 works but is CPU-heavy.
  3. Set Rate Control to CBR.
  4. Set Bitrate to about 9000 kbps for 1080p at 60 fps vertical content.
  5. Set Keyframe Interval to 2 seconds.
  6. Set Profile to High.
  7. Enable B-frames if your encoder supports them.
  8. Test upload speed on speedtest.net; aim for ~20 Mbps upload to hold 9000 kbps with headroom.
  9. If upload is lower, reduce bitrate to roughly 6000–8000 kbps to avoid dropped frames or buffering.

Switch OBS to a Portrait Canvas (1080x1920)

Key Takeaway: Set both canvas and output to 1080 x 1920 for a true vertical layout.

Claim: Matching Base and Output resolutions to 1080 x 1920 ensures a clean portrait stream.

Portrait mode is required for Shorts-style vertical viewing. Pick 60 fps for action; 30 fps is fine for chill talk.

  1. Go to Settings > Video in OBS.
  2. Set Base (Canvas) Resolution to 1080 x 1920.
  3. Set Output (Scaled) Resolution to 1080 x 1920.
  4. Choose Common FPS Values: 60 for fast motion or 30 for talking streams.
  5. Click OK and confirm the vertical preview.

Build a Clean Vertical Scene: Camera, Overlays, Gameplay

Key Takeaway: Compose the face-cam, overlays, and gameplay for a balanced portrait frame.

Claim: Vertical-native scene design reduces cropping issues in Shorts highlights.

Place the camera where it complements gameplay. Use overlays to add polish without clutter.

  1. In Sources, click + and add your camera (Video Capture Device).
  2. Resize and position the face-cam near a corner or top area.
  3. Add a starting screen or countdown via Media Source (loop an MP4/animated overlay).
  4. Optionally use vertical overlay packs from marketplaces to speed up styling.
  5. Add gameplay via Game Capture or Video Capture Device (for capture cards).
  6. Use Transform > Center Horizontally to align quickly.
  7. Tweak composition until camera, overlay, and gameplay feel balanced.

Create and Configure Your YouTube Broadcast

Key Takeaway: A public, well-keyworded broadcast boosts Shorts discoverability.

Claim: Setting privacy to Public helps your vertical stream surface in the Shorts feed.

Title with search-friendly keywords. Tune latency and DVR based on how interactive you want chat to be.

  1. In OBS, open Manage Broadcast (or use YouTube Studio).
  2. Create a new broadcast with a clear, searchable title (e.g., include “Shorts,” “Vertical,” “Live” if relevant).
  3. Write a description with links to your socials and stream details.
  4. Set privacy to Public for discoverability; use Unlisted for testing.
  5. Choose a category and set “Made for kids” appropriately (usually No unless it’s for young children).
  6. Add a thumbnail if desired.
  7. Select latency: Normal or Low based on interactivity.
  8. Enable DVR if you want viewers to scrub back during the live.

Go Live and Monitor Stability

Key Takeaway: Start streaming and keep an eye on stability to prevent dropped frames.

Claim: Unstable upload bandwidth leads to dropped frames or buffering.

Start the stream once your scene and settings are locked. If instability appears, lower bitrate.

  1. Click Create Broadcast, then Start Streaming in OBS.
  2. Confirm your feed appears in YouTube’s Live Control Room.
  3. Watch for warnings about dropped frames or buffering.
  4. If issues occur, reduce bitrate and keep CBR and 2s keyframe interval.
  5. Continue monitoring chat and latency based on your chosen setting.

Turn the VOD into Shorts on Autopilot (with Vizard)

Key Takeaway: Automate highlight detection, clip creation, and scheduling from your live VOD.

Claim: Vizard finds high-engagement moments beyond simple loudness or cuts and outputs ready-to-post shorts.

Manual clipping is slow and misses nuanced moments. A smart clipper accelerates production and consistency.

  1. Stream vertical in OBS with crop-safe framing for Shorts.
  2. After the stream, use the saved YouTube VOD.
  3. Upload the full VOD to Vizard (or connect your account if supported).
  4. Let Vizard scan for attention peaks, drops, pauses, and punchlines to auto-generate multiple clips.
  5. Review quickly, make light trims, and set Auto-schedule (e.g., 3 shorts/week) and target platforms.
  6. Use the Content Calendar to manage, reorder, or pause posts in one place.
  7. Publish on schedule while you focus on your next live.

Integrations and Simulcast Notes

Key Takeaway: You can stream to other platforms or keep horizontal archives alongside vertical.

Claim: Multi-output or re-encode setups let you support Twitch and long-form YouTube while streaming vertical.

If you also stream to Twitch or want horizontal archives, plan outputs. Keep overlays readable within a vertical-safe area.

  1. Consider multi-output or re-encode tools if you need Twitch plus Shorts simultaneously.
  2. Maintain readable overlays; avoid tiny edge text in a vertical crop.
  3. Balance bitrate against your measured upload to protect stability.
  4. Use a simple scene switcher for Starting Soon, BRB, and Ending scenes without breaking the vertical layout.
