Step 2: The Main Transcode (High Bitrate 1080p Ladder) For the primary HLS rendition (8 Mbps), the command looked like this:
ffmpeg -i EL_PRESIDENTE_S02E06_MASTER.mov \ -vf "lut3d=flashback_lut.cube,eq=saturation=0.85:brightness=0.05" \ -c:v libx264 -crf 16 -preset medium \ -ss 00:23:10 -t 00:04:30 \ # Only the flashback scene -c:a copy \ flashback_scene_fixed.mp4 This saved a full day of re-exporting the 180 GB master file. After encoding, a validation script using ffmpeg ensured compliance: el presidente s02e06 ffmpeg
