Making archived MKV recordings searchable
MKV is the format you end up with when a recording matters more than convenience. OBS writes it by default, lecture capture systems favour it, and archivists like it because a Matroska file survives an interrupted recording. The trade-off is that MKV sits outside most consumer workflows.
TranscribeX reads the audio track inside the Matroska container directly, so a stream archive or a recorded seminar can be transcribed without remuxing it to MP4 first. Nothing is re-encoded and the original file is untouched.
For long-form recordings the transcript is often more valuable than the video: it is searchable, quotable, and easy to skim. Export TXT for notes and summaries, or SRT to caption the archive before it goes back online.

Frequently asked questions
MKV (Matroska) is the default output of OBS Studio and many stream and lecture capture tools, because it survives a crash mid-recording better than MP4 does.
No. Upload the .mkv directly — the audio track is read from the container as it is, so you keep the original file untouched.
The cap is 500 MB per upload. Very long archives are best split into segments, which also makes the resulting transcript easier to navigate.
The primary audio track is transcribed. If a recording has separate commentary and game or room audio, export the track you want first for the cleanest result.
Yes. SRT export gives you a timestamped caption file you can upload with the video to YouTube or attach in any player that reads SRT.
