Workflow alternative
MKVToolNix alternative for batch subtitle and audio merging
Import videos, subtitles, and audio tracks in bulk, match episodes automatically or with AI, review the batch, and export clean MKV files.
A few files are easy to handle manually. A full season with loose subtitles, audio tracks, inconsistent filenames, and output names needs a workflow built for batches.
Add source videos, add external tracks, let MediaFlow match season and episode patterns, use AI Match when names are messy, then apply only the suggestions you trust.
MediaFlow strengths
Built for the full batch workflow
Batch import
Bring in a full season or a large folder, then work through the batch from one workspace.
Automatic episode matching
MediaFlow can use season and episode patterns to pair videos with matching subtitles or audio tracks.
AI matching when names are messy
When filenames are inconsistent, AI Match can suggest pairings while leaving you in control of what gets applied.
Review before export
Check matches, settings, filenames, tracks, subtitles, and outputs before MediaFlow writes final files.
