About formats

MTV is a simple raster image format created by Mark T. VandeWettering for the MTV Ray Tracer, a ray tracing program released in 1988 as one of the early publicly available ray tracers distributed through Usenet. The format stores 24-bit RGB images with a minimal text header followed by raw pixel data. The header consists of a single line containing the image width and height as ASCII integers, followed immediately by the pixel data where each pixel occupies three bytes (red, green, blue) arranged in row-major order from top-left to bottom-right. The MTV Ray Tracer itself was significant in the history of computer graphics — distributed freely via the comp.graphics Usenet newsgroup, it introduced many programmers and students to the principles of ray tracing: ray-object intersection, reflection, refraction, shadows, and recursive shading. The MTV format was the program's native output, and its simplicity made it easy for users to write custom viewers and converters on whatever platform they had access to — a practical necessity in the fragmented Unix workstation landscape of the late 1980s. One advantage is extreme implementation simplicity: the format can be read in a handful of lines of code in any programming language, with no libraries, no compression algorithms, and no metadata parsing required — just read two integers and then read width x height x 3 bytes of pixel data. The format's historical significance in the computer graphics community provides another dimension — MTV files from early ray tracing experiments represent primary artifacts from the era when ray tracing transitioned from academic research to accessible software. MTV files are supported by ImageMagick and various legacy graphics tools.

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 MTV to OTB?

MTV requires niche software to open. Converting to OTB lets you share and view your ray-traced renders on virtually any platform.

What programs open OTB?

Any modern image viewer opens OTB — Windows Photos, macOS Preview, GIMP, Photoshop, and web browsers all support it.

What platforms are supported?

The converter works on any device with a browser — Windows, macOS, Linux, iOS, Android. No platform-specific software needed.

Do I need MTV software installed?

No — the converter processes MTV entirely in the cloud. You do not need any computer graphics and ray tracing software on your device to convert.

Can I convert multiple MTV images at once?

Yes — upload several MTV images in one session and convert them all to OTB simultaneously. Batch processing saves significant time.
