Two-pass loudness normalization: Pass 1: Copy the JSON output values (input_i

ffmpeg -i "RCT-778-engsub convert01-33-30 Min.mkv" -vn -af loudnorm=I=-14:TP=-1.5:LRA=11:print_format=json -f null -

Copy the JSON output values (input_i, input_tp, input_lra, input_thresh, target_offset).

Pass 2 (use values from pass1; example shown with placeholders):

ffmpeg -i "RCT-778-engsub convert01-33-30 Min.mkv" -c:v copy -c:a aac -b:a 192k -af "loudnorm=I=-14:TP=-1.5:LRA=11:measured_I=INPUT_I:measured_TP=INPUT_TP:measured_LRA=INPUT_LRA:measured_thresh=INPUT_THRESH:offset=OFFSET:print_format=summary" -c:s copy "tmp_normalized.mkv"

Replace INPUT_* and OFFSET with values from pass1.

(Alternate simpler single-pass: -af loudnorm=I=-14:TP=-1.5:LRA=11 — less accurate)
