PNG-64 (64-bit RGBA)
The ultimate format for transparency precision in VFX and compositing.
PNG-64 is the heavyweight champion of the PNG family. It combines the 16-bit per channel color depth of PNG-48 with a 16-bit alpha channel. This provides 65,536 levels of transparency, compared to just 256 levels in a standard PNG-32. This format is almost exclusively used in high-end visual effects (VFX), 3D rendering, and professional compositing. When you are rendering a CGI character to place into a movie scene, you need the edges to blend perfectly with the background, even after heavy color grading. PNG-64's 16-bit alpha channel ensures that semi-transparent pixels (like motion blur or hair) retain enough data to be manipulated without becoming jagged or discolored.
A PNG-64 file contains four channels: Red, Green, Blue, and Alpha. Each is 16 bits deep (16 x 4 = 64 bits). The 16-bit alpha channel is the defining feature. In an 8-bit alpha channel (PNG-32), a very faint shadow might only have 3 or 4 levels of transparency steps, leading to visible banding when contrast is increased. In a 16-bit alpha channel, that same faint shadow has hundreds of steps, ensuring it remains smooth under any processing.
Like PNG-48, PNG-64 has been part of the standard since the beginning but was largely ignored by the web community due to file size. It found its niche in the 3D and video production industries as a more accessible alternative to formats like EXR or TIFF for storing intermediate render passes.
Truevision TGA (Targa)
The simple, reliable workhorse of video game textures.
TGA (Truevision Graphics Adapter), often called TARGA, is a raster graphics file format created in 1984. It was the first truecolor (24-bit) format for PC cards. Despite its age, it remains incredibly popular in the video game industry and broadcast graphics because it supports an alpha channel (32-bit images) and is extremely simple to parse.
A TGA file starts with an 18-byte header, followed by image identity information, optional color map, and then the pixel data. The pixel data can be raw or RLE compressed. The 32-bit version (RGBA) is particularly valued because the alpha channel is stored as a simple 4th byte per pixel, making it trivial for game engines to use.
Developed by Truevision for their TARGA and AT-Vista boards, which brought broadcast-quality video graphics to the IBM PC. It became the lingua franca of VGA graphics.
