How to Stream Vertical (9:16) Videos Live 24/7

Vertical videos are not just for Shorts. You can run a vertical 24/7 live stream from pre-recorded clips too. The key is simple: keep the aspect ratio, keep the visuals readable, and use a stable streaming-ready output.

Vertical 9:16 video streaming as a 24/7 live broadcast

Why vertical live streams work

Vertical content is easy to watch on mobile. If your audience mainly comes from phones, a vertical live stream can feel natural. It is also a smart way to reuse clips you already have: Shorts, behind-the-scenes, highlights, reactions, quick tutorials.

The biggest advantage of a 24/7 loop is consistency. Viewers can join at any moment, and your channel stays active even when you are offline.

What to prepare before you go live

  • Choose evergreen clips: content that makes sense any day, not only during a trend.
  • Avoid long intros: people join mid-stream, not at the beginning.
  • Keep text inside safe zones: do not place captions too close to the edges.
  • Make volume consistent: big jumps between clips reduce retention.
Tip: a vertical stream works best when every clip is understandable within 3 to 5 seconds. If a viewer is confused, they swipe away fast.

Formats and resolution in Looping Stream

We accept common upload formats (mp4, mkv, mov, avi, and more). After upload, you choose a platform preset, and the video is automatically optimized for streaming.

  • We keep the original aspect ratio, including vertical 9:16 and square videos.
  • The longest side is limited to 1920 px for consistent streaming output.
  • Videos are normalized to a stable 30 fps output for reliable playback.
  • Output format is streaming-friendly MP4 with H.264 video and AAC audio.

Because the output is standardized, the final file size can change. Sometimes it becomes smaller, sometimes larger. Plan storage with that in mind.

How to build a vertical 24/7 playlist

A strong loop feels curated. Do not throw 500 random clips into one playlist on day one. Start small, measure retention, then expand.

Playlist structure that works

  • Core loop: 20 to 60 minutes of your strongest clips.
  • Theme blocks: group clips by topic (tutorials, highlights, Q&A).
  • Rotation: replace weak clips every week or two.

You can also enable shuffle so the playlist order changes automatically. This helps returning viewers avoid seeing the exact same sequence every time.

Stream keys and safety

Your stream key should be treated like a password. Do not share it, do not show it in screenshots, and do not paste it into public chats. If you think it leaked, regenerate it on the platform side.

In Looping Stream, one stream equals one platform stream key. If you want to broadcast to multiple platforms at the same time, you set up separate streams with separate keys.

Length limits and file storage notes

We do not enforce a strict time limit for uploaded videos, but we do not recommend single files longer than 23 hours. For long projects, it is usually better to split into multiple parts.

Files are stored while your plan is active. After deactivation, files remain available for a limited time: 7 days for paid plans, and 2 days for Trial.
