Part 1. Can You Record and Stream 4K with OBS Studio?
Yes. But there are various aspects that need your consideration while doing it practically, from the monitor to streaming platform, camera to internet bandwidth and hardware resources.
1. 4K Monitor
For a 4K screen recording when using OBS Studio, your monitor screen must have a resolution of 3840 x 2160 pixels or higher. Similarly, if you are trying to live stream the screen activity in 4K, you will need a 4K or higher monitor along with a streaming platform that supports 4K live streaming.
2. Streaming Platforms with 4K Support
Keep in mind that not all the streaming platforms allow 4K streamings. For example, Twitch allows you to live stream OBS Studio recordings in 1080p HD rather than 4K UHD. If you insist on streaming 4K contents, you'll lose some frames.
3. Camera That's Able to Record 4K
Undoubtedly, you must have a webcam or digital camera that is able to record 4K or higher resolution, then you get to say record or stream 4K contents with OBS Studio.
4. Sufficient Internet Bandwidth for 4K Streaming
Only a few OTT (Over-the-Top) platforms allow digital content creators to broadcast in 4K resolution. However, most consumer broadband connections aren't powerful enough to support consistent 4K streaming. A bandwidth of at least 25 megabits per second is recommended in general. If your bandwidth is being consumed by other devices in your home, even 25 Mbps will not suffice.
5. Powerful Hardware Resources
OBS Studio is a resource-intensive application that necessitates the use of a powerful graphics card in order to render graphics elements, animations, and gameplay. To avoid lags, dropped frames, or frozen images during 4K live streaming, you'll need a powerful system that can handle the processing and storage requirements. Or else, you can resort to a 4K video converter to downconvert 4k video to avoid the errors or save bandwidth usage.
