A saved editing project is different from a playable media export
Saving an editor project preserves the edit; exporting creates a media file for playback. Keep both when you need future revisions and a shareable result.

Adding files in mkvmerge is different from appending their programme time
Adding can introduce parallel tracks; appending joins corresponding tracks in sequence. Choose the operation that matches the intended timeline.
Changing an MKV language label does not translate its soundtrack
mkvpropedit can modify track header properties in an existing Matroska file. Changing a language code changes metadata, not the spoken content.
Turning on Audacity clipping markers does not repair the recording
The waveform clipping display changes the view. It does not alter samples or reconstruct audio detail lost through clipping.
A video metadata date can shift when UTC interpretation changes
ExifTool documents a UTC convention for integer QuickTime dates and real camera deviations. Record the tag and interpretation before correcting a time difference.
A smooth source can coexist with a choppy OBS recording
OBS must composite and render its own scene. Source playback or game smoothness alone does not establish enough resources for the capture pipeline.
