Video Frame Size
Calculate uncompressed video frame size from resolution, color depth, frame rate, and duration. Online calculator with instant results and interactive charts.
About This Calculator
The Video Frame Size Calculator helps video editors, developers, and content creators determine the raw data size of uncompressed video frames and total file sizes. Enter your video's resolution, color depth, frame rate, and duration to instantly calculate how much storage space your uncompressed video requires.
The frame size is calculated using the formula: Frame Size = Width × Height × (Color Depth / 8). The total uncompressed video file size is then: Total Size = Frame Size × Frame Rate × Duration. This represents the absolute minimum data required to store the video without any compression codec applied.
Understanding uncompressed video sizes is essential for planning storage needs in video production, broadcast engineering, digital cinema, and surveillance systems. Professional workflows often involve 10-bit or 12-bit color depth for greater color accuracy, which significantly increases frame sizes compared to consumer 8-bit video.
Regional Notes
Global: This calculator works with any standard video resolution (NTSC, PAL, or digital cinema). Frame rates of 23.976, 24, 25, 29.97, 30, 50, and 60 fps are supported worldwide. The results are in universally understood metric units (MB, GB).
Key standards: HD (1280 × 720), Full HD (1920 × 1080), 2K DCI (2048 × 1080), QHD (2560 × 1440), 4K UHD (3840 × 2160), 4K DCI (4096 × 2160), and 8K UHD (7680 × 4320). Color depth varies from 8-bit (consumer) to 10-bit/12-bit (professional/HDR).
Frequently Asked Questions
How do I calculate video frame size?
Video frame size is calculated by multiplying the width in pixels by the height in pixels by the color depth in bits divided by 8. For example, a 1920 × 1080 frame at 24-bit color depth has a size of 1920 × 1080 × 3 = 6.22 MB.
What is the frame size of 1920 × 1080 at 24-bit color?
A 1920 × 1080 frame at 24-bit color depth (8 bits per channel RGB) has a raw size of approximately 5.93 MB (6,220,800 bytes). This is calculated as 1920 × 1080 pixels × 3 bytes per pixel.
How do I calculate total uncompressed video file size?
Total uncompressed video size equals frame size multiplied by frame rate and duration in seconds. For a 1920 × 1080 video at 24 fps lasting 60 seconds, total size is 5.93 MB × 24 × 60 = 8.54 GB.
What color depths are commonly used in video?
Common color depths include 8-bit (256 colors, 1 byte per pixel), 16-bit (65,536 colors, 2 bytes per pixel, high color), 24-bit (16.7 million colors, 3 bytes per pixel, true color), and 32-bit (4 bytes per pixel, true color with alpha channel).
How does resolution affect video frame size?
Frame size scales linearly with pixel count. 4K (3840 × 2160) has 4 times the pixels of 1080p (1920 × 1080), so each frame is 4 times larger at the same color depth. A 4K 24-bit frame is approximately 23.7 MB versus 5.93 MB for 1080p.
What is the difference between compressed and uncompressed video size?
Uncompressed video stores every pixel of every frame individually, resulting in very large files. Compression codecs like H.264, H.265 (HEVC), and AV1 use inter-frame prediction and entropy coding to reduce file size by 50-95% while maintaining visual quality.
How many megabytes is a single 4K video frame?
A single uncompressed 4K (3840 × 2160) frame at 24-bit color depth is approximately 23.7 MB. At 30 fps, one second of uncompressed 4K video requires about 712 MB of storage.
