  • How to change mp4 aspect ratio to 16:9 using ffmpeg ?

    20 février 2023, par user1788736

    I got an mp4 video that I copy 4 minute of it using ffmpeg. After uploading to YouTube I noticed the uploaded video has black bars on both side of video(right and left side) !After searching for a way to remove those black bars I found that I need to use yt:stretch=16:9 !However,using yt:stretch=16.9 tag will not remove the black bars on iPhone and Samsung smart tv YouTube app !

    



    could an expert help me change the aspect ratio of original mp4 video to 16:9 using ffmpeg (without losing video quality) for re uploading to YouTube ? Thanks in advance ?

    



    I got two types of source with following information :

    



    1)Resolution:720x576 ,Frame rate:25 . Codec:H264 - MPEG-4 AVC(part 10)(avc1),
2)Resolution:848x480 , Frame rate:24.804393,Codec:H264 - MPEG-4 AVC(part 10)(avc1)


    



    ffmpeg code used to trim the original video :

    



       ffmpeg -i orginalVideo.mp4 -ss 00:25:55 -t 00:04:02 -acodec copy -vcodec copy videoForYoutube.mp4

  • How do I independently fade in/out multiple (3+) overlay texts over video using FFMPEG ?

    10 janvier 2019, par Balpreet_1988

    When I use this code the 1st text fades out when second text fades in. This should not happen in this code :

    I have tried the provided code in multiple ways but this is not working.

    ffmpeg -y -i title.mp4 -filter_complex "[0:v]drawtext=fontsize=100:fontfile=tst.ttf:fontcolor=0xDEB887:shadowcolor=black:shadowx=5:shadowy=5:text='Top 5 Upcoming Samsung':x=50:y=200,format=yuva444p,fade=t=in:st=0.2:d=1:alpha=1[ovr1];[ovr1:v]drawtext=fontsize=100:fontfile=tst.ttf:fontcolor=0xDEB887:shadowcolor=black:shadowx=5:shadowy=5:text='SmartPhones in 2019':x=50:y=400,format=yuva444p,fade=t=in:st=2.2:d=1:alpha=1[ovr2];[0][ovr2]overlay" test.mp4

    This should fade in 1st text at 0.2 seconds which should stay till the end of the video and 2nd text should fade in at 2.2 seconds and remain till end of video.
