About formats

YUV is a raw pixel data format storing images in the Y'UV color model, where image data is separated into a luminance component (Y', representing brightness) and two chrominance components (U/Cb and V/Cr, representing color difference signals). The YUV color model originated with analog color television broadcasting — specifically the NTSC system adopted in 1953 and the PAL system in 1967 — where backward compatibility with existing black-and-white receivers required separating brightness from color information. In digital imaging, the ITU-R BT.601 standard (1982) formalized the digital YCbCr encoding derived from the analog YUV model, defining the conversion matrices and sample precision used by virtually all digital video and broadcast systems. YUV raw files contain no header, compression, or metadata — they are flat sequences of luminance and chrominance samples in a specified ordering (4:4:4, 4:2:2, 4:2:0, or other subsampling ratios), requiring external specification of dimensions, bit depth, and subsampling scheme. The 4:2:0 subsampling mode (where chrominance has half the horizontal and half the vertical resolution of luminance) is particularly common, used by H.264, H.265, AV1, and most consumer video codecs. One advantage is direct video pipeline compatibility: YUV data is the native input format for video encoders, hardware display controllers, and camera sensor ISPs, making raw YUV the most direct representation for frame-accurate video processing and analysis. The perceptual efficiency of the YUV color model is another fundamental strength — separating luma from chroma enables effective subsampling that halves or quarters the color data with minimal visible impact. YUV data is processed by FFmpeg, ImageMagick, and all video processing tools.

FTS is a file extension for the Flexible Image Transport System (FITS), the standard data format used in astronomy since 1981 when it was defined by Don Wells, Eric Greisen, and R.H. Harten at the National Radio Astronomy Observatory, and subsequently endorsed by the International Astronomical Union in 1982. FITS was designed from the outset as a self-describing archival format: each file begins with one or more 2880-byte header blocks containing ASCII keyword-value pairs that describe the data's dimensions, coordinate system, observation parameters, and provenance, followed by data blocks in a variety of numeric types — 8/16/32/64-bit integers and 32/64-bit IEEE floating-point values. FITS supports multi-dimensional arrays (images, data cubes, hypercubes), binary tables for catalog data, and ASCII tables, with multiple Header/Data Units (HDUs) that can coexist in a single file. The format handles specialized astronomical data: spectral cubes, radio interferometry visibilities, multi-extension mosaic images from CCD arrays, and time-series photometry. One advantage is scientific rigor: FITS mandates that all metadata needed to interpret the data physically — coordinate transformations (WCS), photometric calibration, telescope and instrument parameters — travels with the file, eliminating the metadata-loss problem that plagues general-purpose image formats in scientific contexts. The format's longevity and institutional backing is another strength — virtually every observatory, space telescope (Hubble, James Webb, Chandra), and astronomical software package (DS9, IRAF, Astropy) uses FITS as its primary data format.

Frequently Asked Questions

Why convert YUV to FTS?

YUV is a raw uncompressed pixel data in YUV color space used in video encoding, broadcast, and processing pipelines. Converting to FTS makes the content accessible to anyone.

How do I open FTS files?

You can open FTS with SAOImage DS9, FITS Liberator, astronomical tools. No specialized software is needed on most modern systems.

How long does YUV to FTS conversion take?

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

What happens to my file after conversion?

Your uploaded YUV file and the resulting FTS output are automatically deleted from the server within 24 hours to protect your data.

Do I need to install anything?

Nothing to install. The converter operates entirely online in your browser — no plugins, extensions, or software.

Is my YUV data kept private?

Privacy is built in — YUV uploads are purged after processing, and FTS files are auto-deleted within 24 hours.
