Hi, With this command I tried to enhance a short video: ffmpeg -i NET\ Villa\ Burgen.mp4 -vf atadenoise,histeq=0.1:0.11:strong -c:a copy -movflags +faststart NET\ Villa\ Burgen_3.mp4 (using ffmpeg version 5.1.2-0ubuntu1~22.04.sav1.1)
It helps a lot for the first 2 minutes, but from there in the dark staircase the result becomes very ugly. Does anyone have an idea for a better history / contrast filtering? Original: http://www.JUGKoeln.de/Projects/ffmpeg/NET%20Villa%20Burgen.mp4 Result: http://www.JUGKoeln.de/Projects/ffmpeg/NET%20Villa%20Burgen_3.mp4 Additionally: The 2nd result video doesn't play in firefox, but if downloaded first, it plays without problems with VLC Media Player. Any clue, what the cause is? -Ulf _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
