FFMPEG फसल के लिए आदेश और स्थानांतरित वीडियो बाहर बुरा गुणवत्ता में जूम आता

Question

मैं 480 एक sqaure में आमतौर पर 960x720 आयामों के साथ एक mp4 वीडियो को परिवर्तित कोशिश कर रहा हूँ: 480 वीडियो लेकिन यह पता आता है आमतौर पर squished की तलाश में, आदेश

है

"-y -i %s -vf crop=480:480,transpose=%d -threads 5 -metadata:s:v rotate=0 -c:v libx264 -crf 27 -preset ultrafast -c:a copy -bsf:a aac_adtstoasc %s"; 

क्या मुझे कुछ याद आ रहा है, क्या मुझे पहले या कुछ स्केल करने की आवश्यकता है?

** पूर्ण कंसोल आउटपुट जोड़ने संपादित करें। ffmpeg आदेश अद्यतन किया जाता है, लेकिन लक्ष्य अभी भी एक ही रहता है, एक मनमाना वीडियो और वर्ग फसल यह

Answer 1

आप इस (कांट-छांट और आकार घटाने का ख्याल रखता है) की कोशिश कर सकते हैं ... ले

ffmpeg -i input.file -s 480x480 -vf crop=480:480,setdar=1:1,setsar=1:1 output.mp4

-s .. पैमाने (वीडियो कैनवास क्षेत्र)
crop=480:480 केंद्र से फसल जाएगा सेट हो जाएगा अगर आप विशिष्ट उपयोग से की जरूरत है: crop=480:480:pos-X:pos-Y
setdar Displa सेट हो जाएगा y पहलू अनुपात
setsar सेट हो जाएगा नमूना पहलू अनुपात

परिणाम: (स्क्रीन MPC-Home Cinema के माध्यम से MP4 चित्र पकड़ा)
