See what it doesScreen recordings usually need less bitrate than camera footage because most frames contain static UI, text, and cursor movement. Use these as practical starting points before uploading tutorials, product demos, or walkthroughs.
| Recording Type | Recommended Bitrate | Best For |
|---|---|---|
| 1080p UI tutorial | 6-10 Mbps | Most demos and support videos |
| 1080p with webcam | 8-12 Mbps | Tutorials with facecam overlay |
| 1440p product demo | 12-20 Mbps | Crisp app walkthroughs |
| 4K screen recording | 35-60 Mbps | Marketing videos and product launches |
Video bitrate is the amount of data encoded per second of video, typically measured in megabits per second (Mbps) or kilobits per second (Kbps). It's one of the most important settings when exporting, streaming, or uploading video because it directly controls the trade-off between visual quality and file size.
A bitrate that's too low results in compression artifacts — blocky gradients, blurry motion, and banding. A bitrate that's too high wastes storage and bandwidth without a noticeable quality improvement. The goal is to find the sweet spot where quality is excellent and file size stays manageable.
The optimal bitrate depends on three factors: resolution (more pixels need more data), frame rate (more frames per second require proportionally more data), and content complexity (fast motion or high detail needs a higher bits-per-pixel value). Our calculator handles all three with a single quality preset.
These are common bitrate ranges for H.264/H.265 encoding at 30 fps. Actual values vary by codec, content type, and encoding settings.
| Resolution | Standard (SDR) | High Quality |
|---|---|---|
| 720p (1280×720) | 2.5 – 5 Mbps | 5 – 8 Mbps |
| 1080p (1920×1080) | 5 – 10 Mbps | 10 – 20 Mbps |
| 1440p (2560×1440) | 10 – 20 Mbps | 20 – 35 Mbps |
| 4K (3840×2160) | 20 – 40 Mbps | 40 – 80 Mbps |
| 8K (7680×4320) | 80 – 150 Mbps | 150 – 300 Mbps |
Four simple steps to get your recommended bitrate and file size.
Pick your target resolution — 720p, 1080p, 1440p, 4K, or 8K. Higher resolutions need more data per frame.
Select the frame rate (24–120 fps) and enter video length. More frames per second means proportionally more data.
Choose Low, Medium, High, or Ultra. Each preset sets a bits-per-pixel factor that controls visual fidelity.
The recommended bitrate and estimated file size update in real-time as you adjust any setting.
Platforms re-encode your video, so uploading at the right bitrate ensures the best quality after compression.
Knowing your target bitrate prevents dropped frames and buffering for viewers on slower connections.
Screen content (text, UI elements) benefits from higher bitrates at lower resolutions to stay crisp.
When storage matters, calculating file size upfront helps you plan disk space for long recordings.
Smaller file sizes with acceptable quality are essential for apps and mobile web where bandwidth is limited.
