The system's bitrate depends on the quality setting and image content, but common usable ETC1S bitrates are .3-1.25 bits/texel. ETC1S .basis files are typically 10-25% smaller than using RDO texture compression of the internal texture data stored in the .basis file followed by LZMA. For UASTC files, the bitrate is fixed at 8bpp, but with RDO post-processing and user-provided LZ compression on the .basis file the effective bitrate can be as low as 2bpp for video or for individual textures approximately 4-6bpp.

+The .basis and .KTX2 transcoders have been fuzz tested using [zzuf](https://www.linux.com/news/fuzz-testing-zzuf).
So far, we've compiled the code using MSVS 2019, under Ubuntu x64 using cmake with either clang 3.8 or gcc 5.4, and emscripten 1.35 to asm.js. (Be sure to use this version or later of emcc, as earlier versions fail with internal errors/exceptions during compilation.) The compressor is multithreaded by default, but this can be disabled using the -no_multithreading command line option. The transcoder is currently single threaded.
