If you want prerecorded videos to run continuously as a public YouTube livestream, Castr and Gyre offer cloud workflows for that job. Choose between them by comparing plan limits for concurrent streams, resolution, storage, playlists, scheduling and destinations—not by assuming a loop will increase views or revenue.
First, decide what “looping on YouTube” means
YouTube distinguishes ordinary playback from a livestream. Its built-in loop repeats a video or playlist for the person watching it. Castr and Gyre instead let a creator upload prerecorded footage and transmit it as a live broadcast from the cloud. These are different tasks: a normal video loop does not appear to viewers as a live event.
YouTube Help explains how to repeat a video or playlist on computer, mobile and TV or game console: Loop videos or playlists on YouTube.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals.

When Castr is the better fit
Castr may suit a creator who wants prerecorded broadcasts alongside a broader live-video workflow. It describes multistreaming, a website player and plan-dependent storage and bandwidth, in addition to scheduling and playlist loops. The key plan distinction for this specific use is that Castr lists infinite loop mode on Premium and Ultra; Starter and Standard do not include it.
Castr’s pricing page, checked October 3, 2026, lists Premium at $199.99 monthly or $166.67 per month billed annually. The same page lists an entry price of $19.99 per month, or $16.67 per month billed annually; those starting figures do not mean the entry tier includes infinite looping. Confirm the billing term and included features on Castr’s pricing page.

Castr describes Infinite Loop mode this way: “If you choose this mode, your video will go live to the added platforms as a loop, and stream 24×7.” Its help article also describes a separate scheduled-start mode, so distinguish a continuous loop from a broadcast that begins at a planned time: Castr pre-recorded live scheduling modes.
When Gyre is the better fit
Gyre makes concurrent stream capacity and resolution prominent in its plans. That can make the choice more straightforward if you know how many simultaneous HD or 4K streams you need. Its pricing page checked October 3, 2026 lists Start at $49, Start+ at $99 and PRO+ at $169, with a seven-day trial. The page also lists one HD stream for trial and Start, up to four HD or one 4K for Start+, and up to eight HD or two 4K for PRO+.

Playlist and scheduler availability differs by tier: the page lists both for the trial, Start+ and PRO+, but not Start. The trial is not equivalent to a full paid setup: it lists one HD stream, 20 GB of storage and a watermark. Confirm subscription duration, billing and current terms at Gyre’s pricing page.
How to choose for a real channel
- Confirm the task. For personal replay, use YouTube’s loop control. For a public livestream made from prerecorded material, compare cloud streaming plans.
- Count simultaneous channels. Match your actual number of concurrent broadcasts to the plan’s limit. More streams do not inherently mean more views, watch time or revenue.
- Set the resolution target. If you need 4K, check how many 4K streams a tier permits; do not compare an HD allowance with a 4K allowance as if they were equivalent.
- Estimate files and storage. Check each plan’s storage, file-count and file-duration limits against the material you intend to keep online. Castr says these limits vary by tier; Gyre also varies storage by plan.
- Check playlists and timing. Confirm that your selected tier includes playlist looping and any scheduler you need. A one-time scheduled start and an uninterrupted recurring loop are not the same workflow.
- Verify destinations. Select based on the platforms you actually need, and confirm custom RTMP or website-player requirements if relevant.
- Use trials with their restrictions in mind. Castr’s trial is its Starter tier, where advanced looping is not listed. Gyre’s trial lists one HD stream, 20 GB storage and a watermark.
Neither vendor’s reviewed product pages establish that continuous looping will reliably produce algorithmic lift, monetization or audience growth for every channel. Treat promotional growth claims as vendor claims, not a guaranteed outcome.

StreamNeo: another cloud option to compare
For a YouTube-only prerecorded loop, StreamNeo is an alternative to evaluate: it runs continuously from the cloud, supports any uploaded quality up to 4K 60fps at one flat price per slot, and offers a free first day.
StreamNeo’s steps are upload a recording or make a playlist, add your YouTube stream key once, and go live. The computer can be off while the cloud runs the loop; StreamNeo says it automatically recovers if YouTube drops the stream. Each slot includes one always-on stream, 10 GB of storage per slot pooled across active slots, playlists, and team support. StreamNeo streams to YouTube only, and plays uploaded videos rather than broadcasting a camera.
