About formats

UYVY is a packed pixel format for storing images and video frames in YUV 4:2:2 chroma-subsampled color space, with the UYVY designation indicating the byte ordering within each 4-byte macropixel: U (Cb), Y0, V (Cr), Y1. Each macropixel encodes two horizontal pixels sharing a single pair of chrominance samples (U and V) but retaining individual luminance values (Y0 and Y1), achieving 2:1 horizontal chroma subsampling that reduces data size by 33% compared to full 4:4:4 YUV while maintaining full luminance resolution. The UYVY ordering is specified as a FOURCC code in Microsoft's Video for Windows and DirectShow frameworks, and is commonly used in professional video capture cards, broadcast equipment, and video processing pipelines. UYVY raw files contain no header — the pixel data is a flat sequence of U,Y,V,Y byte quadruplets, requiring external specification of image dimensions. The 4:2:2 subsampling exploits the human visual system's lower spatial resolution for color compared to brightness: the eye notices luminance detail at much higher spatial frequencies than chrominance detail, so sharing color samples between adjacent pixels produces no visible quality loss in practice. One advantage is broadcast-standard compatibility: UYVY's 4:2:2 sampling matches the chrominance structure used in professional video standards (ITU-R BT.601, SDI), making it the natural format for video capture hardware and frame-accurate processing. The format's efficient memory layout is another strength — the packed byte arrangement enables fast DMA transfers between capture hardware and system memory. UYVY data is handled by FFmpeg, ImageMagick, and professional video capture/editing software.

OTB (Over-the-Air Bitmap) is a monochrome image format developed by Nokia as part of their Smart Messaging specification in 1997, designed for transmitting small graphics — operator logos, group graphics, and picture messages — to Nokia mobile phones via SMS. OTB files contain 1-bit (black and white) images at small fixed resolutions, typically 72x14 pixels for operator logos and 72x28 pixels for group graphics, encoded in a compact binary format suitable for embedding within the payload of SMS text messages. The format uses a simple structure: a header byte indicating whether the image is an operator logo or group graphic, width and height values, and the raw bitmap data where each bit represents one pixel packed eight per byte. The extremely tight format — designed to fit within a single SMS message (140 bytes maximum payload, shared with addressing overhead) — reflects the severe constraints of mobile communication in the late 1990s. Nokia's Smart Messaging system was one of the first commercial implementations of rich content delivery to mobile phones, and OTB images represented the entire visual content capability of Nokia handsets before MMS and mobile data browsing arrived. One advantage is the format's historical role as a pioneer of mobile visual messaging: OTB images were among the first graphics that ordinary consumers could send to each other's phones, predating MMS, camera phones, and smartphones by nearly a decade. The format's minimal footprint is another characteristic — entire images fit in a few dozen bytes, reflecting an era of extreme bandwidth constraints. OTB files are supported by ImageMagick, various Nokia phone management tools, and specialty mobile format utilities.

Frequently Asked Questions

Why convert UYVY to OTB?

UYVY data from video capture and broadcast equipment becomes universally viewable once converted to OTB format.

How do I open OTB files?

Use mobile device tools to view OTB files. This format enjoys broad software support on all major platforms.

What quality can I expect from OTB output?

Quality depends on the source data, but OTB format provides monochrome mobile bitmap for excellent results.

How long does UYVY to OTB conversion take?

Conversion is fast — usually a matter of seconds. Complex or large UYVY files may need slightly more time.

Can I convert multiple UYVY files at once?

Upload as many UYVY files as you need. Every file processes independently and delivers its own OTB output.

Do I need to install anything?

Convertio is fully browser-based. No desktop software, plugins, or extensions are necessary for UYVY to OTB conversion.
