FastFlix is a free, open-source graphical interface for encoding videos with H.264, HEVC, and AV1 encoders, built on top of FFmpeg. It supports both software encoders (x265, x264, rav1e, AOM/SVT AV1, VP9, VVC) and hardware encoders (Nvidia NVEnc, Intel QSV, AMD VCE, VAAPI, Apple VideoToolbox), including HDR10 and HDR10+ metadata handling.

Use cases

• convert videos to HEVC with HDR10 metadata preserved
• encode AV1 videos with a GUI instead of command line
• compress large video files using hardware GPU encoding
• add HDR10+ dynamic metadata to HEVC encodes
• extract and reattach cover art and subtitles when encoding MP4 or MKV
• batch re-encode a movie library to save disk space
• encode video for Apple devices using VideoToolbox on macOS

When to choose

• you want a friendly GUI over FFmpeg for video encoding
• you need HDR10/HDR10+ support with x265 or AV1 encoders
• you want to leverage GPU hardware encoders from Nvidia, Intel, or AMD
• you need cross-platform encoding on Windows, macOS, or Linux

When to avoid

• you need fully automated, scriptable headless transcoding pipelines (use FFmpeg directly)
• you require a video editor with cutting, trimming, or effects
• your FFmpeg build lacks the encoders you need and you cannot upgrade it
