FastFlix is a handy GUI for encoding videos.
Download latest release from Github
It needs FFmpeg (version 4.3 or greater required, 5.0+ recommended) under the hood for the heavy lifting, and can work with a variety of encoders.
Check out the FastFlix github wiki for help or more details, and please report bugs in the github issue tracker!

If one of the above software encoders is not listed, it is due to your version of FFmpeg not having that encoder compiled in.
These will require the appropriate hardware. Nvidia GPU for NVEnc, Intel GPU/CPU for QSVEnc, and AMD GPU for VCEEnc.
Most of these are using rigaya's hardware encoders that must be downloaded separately, extracted to a directory of your choice, and then linked too in FastFlix Settings panel.
AV1 is only supported on the latest generation of graphics cards specifically the Intel Arc, Nvidia 4000 series and AMD 7000 series

View the releases for binaries for Windows, MacOS or Linux
You will need to have ffmpeg and ffprobe executables on your PATH and they must be executable. Version 4.3 or greater is required for most usage, latest master build is recommended and required for some features. The one in your package manager system may not support all encoders or options.
Check out the FFmpeg download page for static builds for Linux and Mac.
To use rigaya's Nvidia NVENC, AMD VCE, and Intel QSV encoders, download them and extract them to folder on your hard drive.
Windows: Go into FastFlix's settings and select the corresponding EXE file for each of the encoders you want to use.
Linux: Install the rpm or deb and restart FastFlix
On any 10-bit or higher video output, FastFlix will copy the input HDR colorspace (bt2020). Which is different than HDR10 or HDR10+.
FastFlix was created to easily extract / copy HDR10 data, which it can do with the above listed encoders (x265, NVEncC, VCEEncC, QSVEncC).
VP9 has limited support to copy some existing HDR10 metadata, usually from other VP9 files. Will have the line "Mastering Display Metadata, has_primaries:1 has_luminance:1 ..." when it works.
AV1 is still in development, and hopefully all encoder will support it in the future, but only SVT AV1 works through ffmpeg as of now for software encoders.
For Windows users with dedicated graphics cards, the best thing to do is use a hardware encoder, as they all support HDR10+ currently!
FastFlix also supports using generated or extracted JSON HDR10+ Metadata with HEVC encodes via x265. However, that is highly dependent on a FFmpeg version that has been compiled with x265 that has HDR10+ support. BtbN's Windows FFmpeg builds have this support as of 10/23/2020 and may require a manual upgrade.
If you add HDR10+ metadata file, make sure the encoding log does NOT contain the line x265 [warning]: –dhdr10-info disabled. Enable HDR10_PLUS in cmake or else it is unsupported.
FastFlix (v4.0.2+) passes through HLG color transfer information to everything except webp and GIF.
FastFlix does not plan to support Dolby Vision's proprietary format at this time.
