First, extract a reference frame:
ffmpeg -i nezha_fight.mp4 -filter:v "minterpolate='mi_mode=mci:mc_mode=aobmc:vsbmc=1:fps=60'" -setpts=5*PTS -r 60 nezha_slowmo.mp4 Note: This is computationally expensive. For a film as complex as Ne Zha 2 , you are asking your CPU to guess the trajectory of every magical particle. Expect your fan to sound like Ne Zha’s jet propulsion. The film’s score blends traditional Chinese percussion (think zhongshan drums) with Hans Zimmer-esque brass. To visualize the audio dynamics, we can generate a spectrogram. ne zha 2 ffmpeg
ffmpeg -i fate.mkv -c:v libx265 -crf 18 -preset veryslow -tune animation nezha_victory.mkv First, extract a reference frame: ffmpeg -i nezha_fight
ffmpeg -i original.mkv -i compressed.mp4 -lavfi psnr -f null - If the PSNR drops below 38dB in the "Chaos Sea" sequence, the encoder crushed the shadow detail. Ne Zha’s black hair should not merge into the abyss. (Purely hypothetical for archival purposes) . Sometimes, digital releases have hardcoded subtitles or regional broadcast watermarks. While FFmpeg can't un-burn a logo, it can crop it. Ne Zha’s black hair should not merge into the abyss
