There is no universal video-count limit for a 24/7 YouTube streaming service: each provider sets its own media-library rules. For Upstream, the published allowance is as many videos as fit within the plan’s storage, usually 100 GB per stream slot. YouTube has a separate limit for each individual upload: 256 GB or 12 hours, whichever is less. Upstream Helpdesk · YouTube Help
Why the answer depends on the service
“A 24/7 YouTube streaming service” is not one YouTube feature with a shared upload quota. A third-party service stores the videos it loops and applies its own storage or library limits. The number of files you can upload therefore depends on the provider and plan; file count alone does not tell you how much content will fit.
How many videos does Upstream allow?
Upstream’s Helpdesk says users can upload as many videos as they want, provided they stay within their plan’s total storage, which is usually 100 GB per stream slot. That is a storage-based allowance, not a fixed maximum number of files. Larger files use more of the allowance, so fewer will fit.
Upstream’s guide supports MP4, MOV, WebM and Ogg video files, and recommends MP4 with H.264 for compatibility. It also says you can add, remove or rearrange playlist items while streaming. A video library’s upload count is therefore distinct from the number of videos currently arranged in a playlist. Upstream Helpdesk, updated September 16, 2026

What YouTube limits for each video
YouTube’s own upload ceiling is separate from a service’s storage quota. YouTube Help states that an individual video can be up to 256 GB or 12 hours, whichever is less. Accounts that have not been verified are limited by default to videos up to 15 minutes; verification is required to upload longer videos. Older uploads may exceed today’s duration limit because YouTube says its limits have changed over time. YouTube Help
These are per-video upload rules. They do not establish how many files a third-party 24/7 service will store for you.

How the documented services compare
The available provider guidance gives different kinds of limits. Do not apply one service’s storage allowance to another, or treat a scheduling limit as an upload-count limit.
| Service | Published library or file-count limit | 24/7 requirement or duration |
|---|---|---|
| StreamNeo | 10 GB of storage per slot, pooled across active slots; no numeric file-count cap is stated. | Cloud service for looping uploaded videos on YouTube. |
| Upstream | As many videos as fit within plan storage, usually 100 GB per stream slot; no fixed file-count cap is stated. | Its guide describes 24/7 streaming. |
| OneStream Live | The cited guide does not state a maximum number of uploaded videos. | Its 24/7 option requires an Enterprise plan and permits a scheduled duration of up to 30 days. |
OneStream Live’s 30-day figure is a maximum scheduled stream duration, not a video-library quota. Its guide describes adding video from a device, the OneStream library or cloud storage, and says the 24/7 feature is exclusive to YouTube. OneStream Live Help Center, updated September 3, 2026

Check these limits before uploading
- Identify the provider and plan. Look for the provider’s storage allowance, whether it applies per slot or account, and any separate file-count restriction. If the provider does not publish a numeric cap, do not assume one.
- Estimate storage from your actual files. Add the sizes of the videos you plan to keep in the library and compare the total with the service’s allowance. The number that fits changes with file size.
- Check YouTube’s per-video rules. Confirm that each upload is within the 256 GB or 12-hour ceiling and verify the account if a video is longer than 15 minutes.
- Keep live-stream eligibility separate from uploads. YouTube requires a verified channel and no live-stream restriction in the previous 90 days before going live. Its stated limits of 10 active streams per channel and three per stream key are simultaneous-stream limits, not upload counts. YouTube Help
Copyright and reused-content checks for a 24/7 loop
Having room to upload a file does not give you permission to stream it. Use videos and music you own or are authorized to use, and check that your rights cover continuous public streaming. Repeating the same footage does not remove copyright obligations. YouTube’s copyright and monetization policies are separate from a service’s storage quota; review the current rules before building a long-running playlist.
