Goal : Extract key metadata, detect scene changes (e.g., flashbacks to Jamie's prison time), normalize audio, and generate a high-efficiency re-encode with optional subtitle burn-in. 2. Core FFmpeg Command Chain A. Quick Metadata Extraction ffmpeg -i outlander.s04e10.mkv -f null - 2> ep_analysis.txt Extracts codec, bitrate, frame count, duration, and stream info. B. Scene Change Detection (for chapter markers or cuts) ffmpeg -i outlander.s04e10.mkv -filter:v "select='gt(scene,0.4)',metadata=print:file=scenes.txt" -an -f null - Threshold 0.4 works well for dramatic scene shifts (e.g., Brianna's confrontation with Roger). C. High-Efficiency Re-encode (H.265 + Opus) Preserve quality, reduce size ~40-50%: ffmpeg -i outlander
video_stream = next(s for s in data['streams'] if s['codec_type'] == 'video') print(f"Resolution: video_stream['width']xvideo_stream['height']") print(f"Codec: video_stream['codec_name']") Brianna's confrontation with Roger). C.
