A General Guide to Working with Video Files

Why Convert?

1. File size reduction – Converting to H.265 (HEVC) from H.264 shrinks file sizes by ~50%.
2. Device compatibility – Making the video playable on smartphones, tablets, or older media players.
3. Adding subtitles – Burning in subtitles requires re-encoding.
4. Extracting clips – The “23-49” could indicate a clip from 23:00 to 23:49.

7️⃣ Fine‑tuning the output length (“02‑23‑49 Min”)

If the target file must be exactly 2 h 23 m 49 s (i.e., 2 hours 23 minutes 49 seconds) you can:

1. Trim or pad the source to that duration.
2. Verify the duration with ffprobe.

6️⃣ Scenario D – Package everything into a new MKV container (no re‑encode)

If you merely want to re‑wrap the existing streams into a clean MKV, perhaps to rename the subtitle track, you can copy everything without re‑encoding:

ffmpeg -i "JUQ-968‑engsub.mkv" \
       -c copy \
       -metadata:s:s:0 language=eng \
       "JUQ-968‑final.mkv"

This is lossless and extremely fast (just a stream copy).
