Formats & Codecs

Input formats

Medix recognises 20+ common media containers as inputs:

VOB, MP4, MKV, AVI, MOV, WMV, FLV, MPEG, MPG, TS, WebM, M4V, 3GP, OGV, MTS, M2TS, DIVX, ASF, RM, RMVB, F4V.

Files matching these extensions are auto-discovered when you point Medix at a directory. If none are found, Medix exits with a clear message.

Output formats

Format	Default video	Default audio	Best for
MP4	H.264	AAC	Universal playback
MKV	H.264	AAC	Flexible container, multi-track
WebM	VP9	Opus	Web streaming
MOV	H.264	AAC	Apple ecosystem
AVI	H.264	MP3	Legacy compatibility
TS	H.264	AAC	Broadcast / streaming

You can override any of these defaults via advanced settings.

Multi-format source handling

When a directory contains multiple input formats, Medix prompts you to pick which ones to include:

? Multiple source formats found. Which should I convert?
  [x] .vob (12 files)
  [x] .mpg (3 files)
  [ ] .avi (1 file)

Unselected formats are skipped entirely.

Copy vs re-encode

For both video and audio, copy is available as a codec option. This does a container remux without re-encoding — fast, lossless, but only valid when the source codec is compatible with the target container.
