Subtitle Muxer 0.1.0

Subtitle Muxer 0.1.0

First public release. Copy soft subtitle tracks from a source video onto a target video (for example an upscaled encode) with no re-encoding — FFmpeg stream copy only. FFmpeg is bundled in the app.

What’s included

• Source + target file pickers (browse or drag-and-drop)
• Subtitle track list with language / format / title; select which tracks to copy
• Remembered destination folder and filename
• Output as MKV (recommended) or MP4
• Built-in FFmpeg log panel
• About dialog with support link

Tips

• Prefer MKV when possible. Some subtitle formats (ASS, PGS, and others) do not copy cleanly into MP4.
• Soft subtitle tracks can be copied. Burned-in or video-baked captions cannot.
• If a track does not appear in the list, that file likely has no separate subtitle streams.
