If you’re working with original datasets (~500 GB) and need to save space, re-encoding to H.265 can dramatically (~100 GB) reduce file size with minimal quality loss.

You can use ffmpeg, for example.

ffmpeg -i ./normanniles1_2025-10-20-12-54-45.mp4 \
-c:v libx265 -preset slow -crf 28 -c:a aac -b:a 128k \

./normanniles1_h265.mp4
