Video Bitrate Calculator
Calculate the optimal video bitrate for streaming, uploading, or encoding. Get recommendations for YouTube, Twitch, and other platforms based on resolution, frame rate, and codec.
How to Use the Video Bitrate Calculator
- Select your target video resolution from the dropdown or choose "Custom" to enter specific dimensions
- Choose the frame rate for your video (30fps for standard content, 60fps for smooth motion and gaming)
- Select your video codec - H.264 offers maximum compatibility, while H.265/HEVC provides better compression
- Pick a quality level based on your use case: low for streaming, medium for standard, high for quality-focused, or ultra for archival
- Click "Calculate Bitrate" to see recommended, minimum, and maximum bitrate values
- Use the platform presets for quick settings optimized for YouTube, Twitch, or Vimeo
What is Video Bitrate?
Video bitrate is the amount of data processed per second in a video file, measured in kilobits per second (kbps) or megabits per second (Mbps). It directly determines the quality and file size of your video. Higher bitrates mean more data is used to represent each frame, resulting in better image quality, more accurate colors, sharper details, and smoother gradients. However, higher bitrates also produce larger files that require more storage space and bandwidth to stream.
Finding the optimal bitrate requires balancing quality against practical constraints like storage capacity, upload bandwidth, and streaming platform limits. An excessively high bitrate wastes space without visible quality improvement, while too low a bitrate causes compression artifacts like blocking, banding, and blurriness. This calculator helps you find the sweet spot for your specific resolution, frame rate, and codec combination.
Bitrate Calculation Formula
The recommended bitrate is calculated based on multiple factors:
Bitrate = Width x Height x FPS x BPP x Codec Factor
Where BPP (Bits Per Pixel) is a quality factor typically ranging from 0.05 (low quality) to 0.2 (archival quality) depending on content type and desired quality. Fast-moving content like sports or gaming benefits from higher BPP values, while static content like tutorials can use lower values.
Codec Efficiency Comparison
- H.264 (AVC): The most widely compatible codec, supported by virtually all devices and platforms. Serves as the baseline for bitrate calculations. Best choice when compatibility is paramount.
- H.265 (HEVC): Approximately 40-50% more efficient than H.264 at the same quality level. Requires more processing power for encoding and decoding. Ideal for 4K content and when file size is a concern.
- VP9: Google's open-source codec with efficiency similar to H.265. Primarily used by YouTube and supported in most modern browsers. Good balance of quality and compatibility.
- AV1: The newest codec, offering roughly 30% better efficiency than H.265. Requires significant encoding time but produces excellent results. Increasingly supported by streaming platforms.
Platform-Specific Recommendations
- YouTube: Recommends 8 Mbps for 1080p30, 12 Mbps for 1080p60, and 35-45 Mbps for 4K. Upload in the highest quality possible as YouTube will re-encode.
- Twitch: Maximum 6000 kbps for most streamers, 8500 kbps for partners. Resolution should match your bitrate capability - 720p60 at 4500 kbps or 1080p60 at 6000 kbps.
- Vimeo: Accepts higher bitrates than YouTube, up to 20 Mbps for 1080p. Recommended for quality-focused content.
- Social Media: Instagram, TikTok, and Facebook typically re-compress heavily, so upload at their maximum supported bitrates.
Tips for Choosing the Right Bitrate
- Test your export at different bitrates and compare quality before committing to a final render
- Action-heavy content (sports, gaming, fast motion) requires 20-30% higher bitrates than static content
- When streaming live, set bitrate 20% below your upload speed to prevent buffering
- For archival purposes, use the ultra quality setting to preserve maximum detail
- Variable bitrate (VBR) encoding can produce better results than constant bitrate (CBR) for the same average file size
