| Copy files with verification – use tools like rsync --checksum or Windows Robocopy /MIR to ensure the copy is identical. |
| Avoid abrupt power loss – always safely eject external drives. |
| Store originals on reliable media – SSDs or high‑quality HDDs; keep backups (cloud + offline). |
| Use a download manager that validates checksums (e.g., aria2c with SHA‑256). |
| Keep software updated – newer VLC/ffmpeg versions handle edge‑case containers better. |

HandBrake will read every readable frame and output a clean MP4. This may slightly reduce quality, but you can control bitrate/CRF to keep it high (e.g., CRF 20). If the audio drifts, re‑timestamp the streams: ffmpeg
Command‑line equivalent with ffmpeg:
ffmpeg -i "broken_Amma_Magan_Uravu.mp4" \
-c:v libx264 -preset medium -crf 20 \
-c:a aac -b:a 192k \
"reencoded_Amma_Magan_Uravu.mp4"
