  • How to get the highest resolution, dividable by 2 that contains the video without black borders after rotation ?

    22 avril 2016, par Vitalis Hommel

    I rotate a video. Then my goal is to get the biggest resolution, dividable by 2 that contains the video without black borders.

    rotated and bigger

    to

    rotated, smaller and dividable by 2

    My approach.

    ffmpeg -ss 6 -i "t.MP4" -ss 0 -t 5 -vf "rotate='8*PI/180:ow=hypot(iw,ih):oh=ow', scale='1920:1920', crop='1920:1080:0:420'" -c:v libx264 -crf 28 -acodec copy "t2.MP4"

    But that does not meet the criteria. Which command do I need ?

  • Concatenate videos and add black frames between them with ffmpeg

    25 avril 2016, par user3406207

    I have three videos that I am concatenating with ffmpeg. I would like to add a few black frames in between them. Although I’ve found a few hints on the web it has not worked for me yet. I have tried to generate an ’empty’ video with just black frames with :

    ffmpeg -t 20 -s 1920x1080 -f rawvideo -pix_fmt rgb24 -r 25 -i c:\nul  E:\empty.avi

    and then concatenate with another one but doesn’t work. I have tried a few other things without success. Any help would be greatly appreciated

    EDIT : also tried to add black frames before and after video with the following code, but no success :

    ffmpeg -f lavfi -i color=c=black:s=1920x1080:r=25:d=100 -i middle_video.avi -filter_complex 
    
"[0:v]trim=start_frame=1:end_frame=21[blackstart];
    
[0:v] trim=start_frame=1:end_frame=21 [blackend]; 
    
[blackstart] [1:v] [blackend] concat=n=3:v=1:a=0[out]" -map "[out]" -c:v qtrle -c:a -copy output.avi
