FastFlix is a simple and friendly GUI for encoding videos. FastFlix keeps HDR10 metadata for x265, NVEncC HEVC, and VCEEncC HEVC, which will also be expanded to AV1 libraries when available. It needs FFmpeg (version 4.3 or greater) under the hood for the heavy lifting, and can work with a variety of encoders.

All features
HDR
On any 10-bit or higher video output, FastFlix will copy the input HDR colorspace (bt2020). Which is different than HDR10 or HDR10+.
HDR10
FastFlix was created to easily extract / copy HDR10 data, which it can do with the above listed encoders (x265, NVEncC, VCEEncC).
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 as such none of them currently support setting mastering-display data through FFmpeg (aka not supported with FastFlix), but some do if you use them directly.
rav1e - can set mastering data and CLL via their CLI but not through ffmpeg.
SVT AV1 - accepts a "--enable-hdr" flag that is not well documented, not supported through FFmpeg.
aomenc (libaom-av1) - does not look to support HDR10
HDR10+
For Windows users with Nvidia cards, NVEncC is the best option currently to use HDR10+.
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.
HLG
FastFlix (v4.0.2+) passes through HLG color transfer information to everything except webp and GIF.
On any 10-bit or higher video output, FastFlix will copy the input HDR colorspace (bt2020). Which is different than HDR10 or HDR10+.

Hi, google and copilot both keep saying that FastFlix can do AUTO CRF (like a VMAF scan) where it will test the source and dynamically find the optimal CRF value for the source in question.
i have spent all day on it, and no matter how hard i try, i cannot get this option to show. in fact at one point i even got in a strong disagreement with Gemini, because not only after following all steps, the option i should have still does not appear. along with this, both AI's failed to actually find me a single post or something where it's confirmed that FastFlix doers in fact have the ability to auto find the best Visual CRF value for the user.

Unable to size main screen. Unable to encode with hardware cuda encoding. This seems like a partially finished program, not yet ready for release.
