Hybrid is a multi platform (Linux/Mac OS X/Windows) Qt based frontend for a bunch of other tools which can convert nearly every input to x264/Xvid/VP8 + ac3/ogg/mp3/aac/flac inside an mp4/m2ts/mkv/webm/mov/avi container, a Blu-ray or an AVCHD structure.

Features:

• extensive ability to configure x264s setting (with dependency checks)
• ability to configure x265s setting
• tagging support for mkv/mp4/mov
• chapter support for mkv/mp4/Blu-ray
• subtitle suppot for mkv/mp4/Blu-ray
• separated audio-, video-, filter profiles, audio&video combi profiles
• an integrated bitrate calculator
• accepts vc-1 and avc raw input
• manual&automatic creation&pass-through of chapters
• ability to encode single title/chapters
• a job-control
• aac/mp3/ac3/ogg/flac/dts/pcm audio encoding with dcaenc/mencoder/ffmpeg/aften and different aac encoders
• supported aac encoders: qaac, fdk, faac, fhg, neroaacenc, vo-aacenc
• filtering through mencoder (+ some resize automation) or avisynth if the 'avisynth extension' is used
• acceptable Input: avs and everything that mplayer/ffmpeg can decode
• supported video output formats: MPEG-4 ASP (Xvid), MPEG-4 AVC (x264, cuda, qsvencc), VP8/VP9 (vpxenc), ProRes (ffmpeg), MPEG-4 HEVC (x265, kvazaar), FFV1, UT video
• supported audio output formats: dts, ac3, ogg vorbis, mp3, aac, flac, pcm, opus, pass-through
• supported containers: mov/mp4/mkv/m2ts/webm/avi, Blu-ray or a AVCHD structure
• audio/video pass-through -> can be used for muxing, tagging, chapter editing
• a lot of option to automate stuff

Requirements:
OS X 10.8+
64-bit Intel
