Create a custom stream key in YouTube Studio, then schedule each broadcast separately in Live Control Room. For each event, send your encoder’s feed to YouTube using the stream URL and that key; when the incoming preview appears, click Go live. The key can be reused, but it does not create a permanent scheduled event.
What persists—and what does not
A custom stream key is a reusable credential for connecting an encoder to YouTube. It is not the broadcast itself, a public watch link, or a schedule. You still create or select an event in Live Control Room’s Manage tab for each broadcast.
YouTube describes the stream key as the stream’s “password and address”: it tells the encoder where to send the feed and allows YouTube to accept it. Keep it private. Anyone who obtains it may be able to send content to the associated stream.
Create a custom stream key
- In YouTube Studio, select Create → Go Live to open Live Control Room.
- Open the Stream tab.
- Select Select stream key → Create new stream key, then create a custom key.
- Copy the key and store it securely. Enter it in the stream-key field of the encoder you plan to use.
The custom key is the part that makes it possible to reuse the encoder credential. It does not make a scheduled broadcast recur automatically.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Schedule the broadcast and connect your encoder
- In Live Control Room, open Manage and choose Schedule stream.
- Choose Reuse settings to copy an earlier stream’s metadata, settings, and key, or choose Create new for a fresh configuration. YouTube says reused settings can be changed after the new stream is created.
- At broadcast time, enter YouTube’s stream URL in the encoder’s server or RTMP field, and enter the selected stream key in its key field. The encoder needs both values.
- Start the encoder and wait for the incoming preview in Live Control Room.
- Check the preview, then click Go live to start the audience-facing broadcast.
- When finished, end the broadcast in YouTube, then stop the encoder from sending content. YouTube says streams under 12 hours are automatically archived.
Choose between a fresh setup and reused settings
| Choice | What it does | When it fits |
|---|---|---|
| Create new | Creates a new scheduled stream configuration. | Use it when the event needs a distinct setup or you do not want to carry forward earlier metadata and settings. |
| Reuse settings | Copies an earlier stream’s metadata, settings, and key into the new scheduled stream; the copied settings can be edited afterward. | Use it when you want to retain a familiar configuration while still creating a separate upcoming event. |
In either case, scheduling remains a separate step in Manage. Reusing a key—or reusing settings that include a key—does not keep one scheduled event active indefinitely.
Prepare and test before the event
- YouTube recommends setting up the encoder at least 2 hours before the event.
- YouTube recommends starting the encoder at least 15 minutes before the scheduled start. This gives you time to check the preview and address connection problems; it does not require starting the audience-facing event early.
- Test the workflow ahead of time. If you need to check access, YouTube’s tips mention using an appropriate visibility setting such as public or unlisted for a test.
- Confirm that the event is accessible from the channel and watch pages, and check the incoming preview before selecting Go live.
- After ending the broadcast on YouTube, stop the encoder.
Software or hardware encoder?
An encoder is needed for this workflow, but YouTube does not require that it be a physical device. YouTube identifies software encoding programs as an option and says expensive equipment is not necessary to begin. Its recommendation of professional-grade hardware encoders is for higher-production events, not a prerequisite for reusing a key with a scheduled broadcast.

Troubleshoot common problems
No incoming preview appears
Check that the encoder is sending to YouTube’s stream URL and that the correct stream key is entered in the encoder’s key field. Confirm that the encoder is running, then allow time for the preview to appear before trying to go live.
The key works, but the event is not scheduled
A key only supplies the encoder credential. Open Live Control Room’s Manage tab and create or select the scheduled stream; then connect the encoder to that event.

The wrong metadata or configuration carried over
If you chose Reuse settings, review the new stream’s copied metadata and settings. YouTube says they can be edited after creation. For a configuration that should not inherit the earlier setup, create a new stream instead.
The key may have been exposed
Reset the key in Live Control Room, then replace the old value in the encoder with the new one. YouTube says only a channel owner or manager can reset a stream key.

The preview is ready, but the broadcast has not started
Starting the encoder sends the feed to YouTube; it is not the same as starting the audience-facing event. Once the preview is present, select Go live in Live Control Room.
