Most home internet uploads max out at 10-50 Mbps. A VPS with 1 Gbps bandwidth opens up possibilities that simply aren't available on residential connections.
What 1 Gbps Enables
| Scenario | Bandwidth Needed | Home Upload | VPS |
|---|---|---|---|
| 1080p60 single stream | 6-8 Mbps | Possible | Easy |
| 1080p60 to 3 platforms | 18-24 Mbps | Borderline | Easy |
| 4K30 single stream | 20-35 Mbps | Difficult | Easy |
| 4K60 production quality | 40-80 Mbps | Impossible | Easy |
| Multi-camera 1080p | 30-50 Mbps | Impossible | Easy |
With 1 Gbps, bandwidth is never the bottleneck. Quality decisions are driven by CPU power and platform limits, not by how much data you can upload.
4K Streaming
Platform Support
| Platform | Max Resolution | Max Bitrate | 4K Support |
|---|---|---|---|
| YouTube | 4K60 | 51 Mbps | Yes |
| Twitch | 1080p60 | 8.5 Mbps | No (partner only) |
| Kick | 1080p60 | 8 Mbps | Limited |
YouTube is currently the best platform for high-resolution streaming. Twitch limits non-partners to 1080p60 at 8.5 Mbps.
FFmpeg 4K Configuration
ffmpeg -re -i input.mp4 -c:v libx264 -preset medium -b:v 35000k -maxrate 40000k -bufsize 80000k -g 120 -sc_threshold 0 -c:a aac -b:a 320k -ar 48000 -f flv "rtmp://a.rtmp.youtube.com/live2/YOUR_KEY"
At 35 Mbps with the "medium" preset, 4K content looks clean even in high-motion scenes.
Multi-Platform at Maximum Quality
With 1 Gbps, you can send maximum quality to every platform simultaneously:
application live {
live on;
# YouTube at 4K (35 Mbps)
exec_push ffmpeg -i rtmp://localhost/live/$name
-c:v libx264 -preset medium -b:v 35000k -s 3840x2160
-c:a aac -b:a 320k
-f flv rtmp://a.rtmp.youtube.com/live2/YT_KEY;
# Twitch at 1080p (8 Mbps)
exec_push ffmpeg -i rtmp://localhost/live/$name
-c:v libx264 -preset veryfast -b:v 8000k -s 1920x1080
-c:a aac -b:a 160k
-f flv rtmp://live.twitch.tv/app/TWITCH_KEY;
# Kick at 1080p (6 Mbps)
exec_push ffmpeg -i rtmp://localhost/live/$name
-c:v libx264 -preset veryfast -b:v 6000k -s 1920x1080
-c:a aac -b:a 128k
-f flv rtmp://kick-ingest/KICK_KEY;
}
Total upload: ~50 Mbps. On a 1 Gbps connection, that's 5% utilization. Your stream quality never fluctuates due to bandwidth congestion.
Multi-Camera Streaming
Professional look with multiple camera angles:
| Camera | Resolution | Bitrate | Purpose |
|---|---|---|---|
| Main | 1080p60 | 6 Mbps | Primary view |
| Overhead | 1080p30 | 4 Mbps | Top-down for crafting/building |
| Facecam | 720p30 | 2 Mbps | Webcam feed |
| Screen capture | 1080p60 | 8 Mbps | Desktop/gameplay |
All feeds can be sent to a VPS running OBS or vMix for cloud-based production switching.
Bandwidth Optimization
Even with 1 Gbps, optimize to ensure consistency:
CBR (Constant Bitrate): Always use CBR for live streaming. VBR (Variable Bitrate) causes buffering when bitrate spikes exceed available bandwidth temporarily.
Keyframe interval: Set to 2 seconds (matching platform requirements). Shorter intervals increase bandwidth usage but improve stream responsiveness.
Dual encoding: If your VPS CPU can handle it, encode at high bitrate for recording and lower bitrate for streaming simultaneously.
Space-Node VPS plans include 1 Gbps connections with generous bandwidth allocations. For streaming, this means your VPS never becomes the quality bottleneck, letting you push the highest quality each platform accepts.
