These are Castr per-stream playlist limits—not a verified limit for playlists created directly on YouTube. Castr’s product page lists the plan counts.
What the Castr limit counts
Castr’s pre-recorded streaming feature plays uploaded or imported video files as a live broadcast at a chosen time, and can deliver that broadcast to YouTube. The file count applies to the playlist within that Castr stream. It does not describe an ordinary YouTube video upload or establish how many videos YouTube allows in a native YouTube playlist.

Castr’s product page says, “No encoder or live source is needed.” That describes this pre-recorded workflow: Castr plays the media as the broadcast rather than requiring a live camera or encoder input.

Other limits to check before building a playlist
Playlist count is only one constraint. Castr says storage, maximum file duration, concurrent pre-recorded streams, loop availability, and destination limits vary by subscription. Its product page lists maximum file durations of 60 minutes on Starter, 120 minutes on Standard, and 240 minutes on Premium and higher. The available plan information does not provide a complete, durable matrix for every limit, so check the current plan details for your account.
How Castr pre-recorded streaming works
- Prepare the files. Castr’s Help Center says this workflow supports MP4 files. You can upload from your computer or import from cloud storage. File size and the number of media files you can add depend on your subscription.
- Choose a broadcast mode. Castr describes scheduling a start date and time or looping the playlist. In Castr’s scheduler, the selected schedule uses the device’s time zone.
- Set the destination. Castr can send the resulting live broadcast to YouTube. Other destinations and the number available depend on the plan.
- Check the playlist against your tier. Make sure both the number of files and each file’s duration and storage requirements fit your current subscription.
Castr describes a pre-recorded stream as a standard live feed playing at a chosen time. That differs from an on-demand video, which viewers start individually from a video library.

Video encoding recommendations are separate from playlist limits
Castr’s recorded-video recommendations page, published December 18, 2023, specifies MP4, constant bitrate, a 2-second keyframe interval, Full HD (1920×1080), 30 FPS, and 4,000 Kbps. These are recommendations, not the playlist file limit or requirements established by the plan-count page. Because the recommendation page is older, check Castr’s current guidance before encoding specifically to those settings.
Do these 3 things before closing this tab:

The Castr figures above cannot answer how many videos you can add to a playlist created on YouTube itself. The sources cited here establish Castr’s per-stream configuration, not YouTube’s native playlist quota. Treat those as separate questions rather than applying Castr’s plan limits to YouTube.
