How impactful is 4K streaming on Twitch for both creators and viewers in terms of engagement and overall experience?
Twitch's maximum bitrate is 6000 Kbps, which is not sufficient for 4K streaming, which requires a minimum of 25 Mbps or more.
4K streaming demands more encoding power and a higher bitrate, making it challenging for most viewers to notice the difference between 1080p and 4K streaming.
Twitch allows streamers to transmit up to three concurrent streams at different resolutions and quality levels, but most non-partner or affiliate streamers cannot stream at a resolution higher than 1080p due to Twitch's bitrate limit.
Streaming in 4K requires more bandwidth and encoding power, making it difficult for most streamers to achieve, especially on lower-end hardware.
The video quality option on Twitch live streams only goes as high as 1080p at 60fps, and most viewers will not notice the difference between 1080p and 4K streaming.
Twitch is experimenting with 4K and AV1 streaming on RTX 40-series GPUs, but it's unclear when 4K streaming will become a standard feature on the platform.
The Enhanced Broadcasting Beta feature allows streamers to create multiple encodings of their stream using dedicated encoder resources in their GPU, making it possible to stream at higher resolutions like 4K.
1440p does not provide a clean, full-integer downscale to 1080p, resulting in more downscale artifacting compared to 4K, which has a larger resolution with fewer pixels.
Upscaling technology, like NVIDIA's AI upscaling, can significantly improve video quality by maintaining detailed information and reducing artifacting.
The best bitrate for Twitch streams depends on the type of content being streamed, with more action-packed gameplay requiring higher bitrates to maintain smooth playback.
The maximum bitrate for Twitch streams is 6000 Kbps for video and 320 Kbps for audio, and aiming for the unofficial maximum of 8000 Kbps may negatively impact stream quality.
Twitch is also experimenting with multiencode livestreaming and AV1 streaming, which could pave the way for 4K streaming in the future.
