FastFlix
Encode videos with FastFlix, a free desktop interface for H.264, HEVC and AV1 hardware or software encoders.
About FastFlix
FastFlix is a free desktop GUI for encoding video with H.264, HEVC and AV1 using software or hardware encoders. It runs on Windows, macOS and Linux and relies on FFmpeg under the hood, offering software encoders such as x264, x265, rav1e, AOM AV1, SVT AV1, VP9 and VVC, plus hardware encoding through NVEnc, QSVEnc, VCEEnc, VAAPI and Apple VideoToolbox. It can copy HDR10 metadata, pass through HLG color transfer information, and copy existing Dolby Vision metadata for HEVC and AV1 with rigaya's hardware encoders.
Setup depends on external components. FFmpeg and ffprobe executables must be on the PATH, with version 4.3 or greater required and 5.0+ recommended; the version in a package manager may not include all encoders. Hardware encoders require matching hardware, and most rigaya encoders for Nvidia, Intel and AMD must be downloaded separately and linked in the Settings panel, though FastFlix can download them automatically on Windows. AV1 hardware encoding is limited to Intel Arc, Nvidia 4000 series and AMD 7000 series cards.
