    Even though I have installed the scikit-video and installed ffmpeg, I still meet this problem :
    
No module named 'skvideo.io.ffmpeg

    


    Output :

  • ffmpeg combining multiple commands into one

    13 septembre 2021, par Richard

    Justing wondering how to combine below commands into one, I have searched how to combine simple filters with comma and complex filter with colon, but I'm not sure how to do this.

    &#xA;

    Basically I want the output of the first command to be the input of the second.

    &#xA;

    Command 1 : concatenate multiple clips into one with different xfade transitions.

    &#xA;

    Command 2 : add a fade in for a video

    &#xA;

    ffmpeg -i input0.mp4 -i input1.mp4 -i input2.mp4 -i input3.mp4 -i input4.mp4 -filter_complex "[0:v][1:v]xfade=transition=fade:duration=0.500:offset=27.486[v01];[v01][2:v]xfade=transition=fadeblack:duration=1.000:offset=31.531[v02];[v02][3:v]xfade=transition=fadeblack:duration=1.000:offset=42.972[v03];[v03][4:v]xfade=transition=fade:duration=0.500:offset=94.149,format=yuv420p[video];[0:a][1:a]acrossfade=d=0.500:c1=tri:c2=tri[a01];[a01][2:a]acrossfade=d=1.000:c1=tri:c2=tri[a02];[a02][3:a]acrossfade=d=1.000:c1=tri:c2=tri[a03];[a03][4:a]acrossfade=d=0.500:c1=tri:c2=tri[audio]" -map [video] -map [audio] -movflags &#x2B;faststart output.mp4&#xA;&#xA;ffmpeg -i input.mp4 -vf "fade=t=in:st=0.000:d=1.000:color=black" -c:a copy output.mp4&#xA;

  • FFmpeg add a text to last image only

    29 mai 2018, par BentCoder

    I managed to create a video from set of non-sequential images and attached an audio to it. Also I added a "Copyright" text on top right hand corner so that the text appears throughout the video. However, I would like that text to appear only on the last image. How should I change my code below to address this ?

    ffmpeg \
    -thread_queue_size 512 -f image2 -pattern_type glob -framerate 1/3 \
    -i '*.jpg' \
    -i 'audio.mp3' \
    -c:a aac -c:v libx264 \
    -vf scale=640:480, format=yuv420p, drawtext="text='Copyright':fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5:x=w-tw-5:y=5" \
    -preset medium \
    video.mp4
