How can we help?

It depends on the file size and length. You can watch the live status in your library as EndlessLive converts each upload — most files are ready within a few minutes.

This is a YouTube setting. In YouTube Studio, your stream latency has to be set to "Normal" — YouTube's "Low" and "Ultra-low" latency modes don't support 4K. Switch to "Normal" latency and your 4K stream will come through.

EndlessLive monitors your stream and automatically tries to restart it if it drops. If it can't recover on its own, it sends an email alert so you can step in and get it running again.

Open Settings → Billing and choose "Manage billing". You can cancel anytime — an ordinary cancellation normally takes effect at the end of the current paid month. There is also a no-login cancellation page at endlesslive.tv/cancel.

Yes, in Settings → Billing. An upgrade takes effect immediately — you see the new plan, the prorated amount for the current period and the new recurring price before you confirm. A downgrade takes effect at the start of your next billing period, and you can cancel a pending downgrade at any time before then.

Both are in Settings → Account. Changing your email sends a confirmation code to the new address to verify it's yours; changing your password sends a notification to your email afterward so you're notified of the change.
