  • Combining three or more videos with ffmpeg and the xfade filter

    25 février 2021, par sil

    As of 2020 ffmpeg has the xfade filter which can combine videos with a transition. Combining two videos is easy enough :

    


    ffmpeg -i vid1.mp4 -i vid2.mp4 \
  -filter_complex [0][1]xfade=transition=pixelize:duration=1:offset=4,format=yuv420p" \
  out.mp4


    


    But I don't understand how to combine three videos (so that v1 fades into v2 and v2 then fades into v3. I tried something like this :

    


    ffmpeg -i vid1.mp4 -i vid2.mp4 -i vid3.mp4 \
  -filter_complex [0][1]xfade=transition=pixelize:duration=1:offset=4,format=yuv420p[0n1];[0n1][2]xfade=transition=pixelize:duration=1:offset=9,format=yuv420p" \
  out.mp4


    


    but that doesn't work. My idea was that 0 and 1, or vid1 and vid2, would be combined into a [0n1] stream with a transition by xfade, and then that 0n1 stream could be combined with vid3 with another filter. As far as I can tell, this includes the first two videos but not the third. What this of course means is that I don't understand how to specify a filtergraph correctly !

    


    How should I use xfade to combine 3 or more videos with transitions between them ?

    


    A full example is as follows. Here I'll use three images (because then issues with combining videos at different frame rates are avoided), and smash them all to 500x500 for ease (in the final version they would be letterboxed to keep resolution and so on).

    


    ffmpeg \
  -loop 1 -t 5 -i tests/p1.jpg \
  -loop 1 -t 5 -i tests/p2.jpg \
  -loop 1 -t 5 -i tests/p3.jpg \
  -filter_complex "[0]scale=500:500[s0];[1]scale=500:500[s1];[2]scale=500:500[s2];[s0][s1]xfade=transition=pixelize:duration=1:offset=4,format=yuv420p[s01];[s01][s2]xfade=transition=pixelize:duration=1:offset=9,format=yuv420p" out.mp4


    


    I would expect this to create a video which was :

    


      

    • 4 seconds of p1.jpg

      • 


    • a pixelise transition into p2.jpg lasting 1 second

      • 


    • 4 seconds of p2.jpg

      • 


    • a pixelise transition into p3.jpg lasting 1 second

      • 


    • 4 seconds of p3.jpg

      • 


    


    but what I actually get is

    


      

    • 4 seconds of p1.jpg

      • 


    • a pixelise transition into p2.jpg lasting 1 second

      • 


    • 4 seconds of p2.jpg

      • 


    


    and then the video ends. p3 is not included at all.

    


    The output is as follows :

  • How to overlay 2 videos, one is main second one is overlaying it, and play sound simultaneously. using FFMPEG in ANDROID STUDIO

    6 août 2020, par Dusan Lilic

    as title say I'm trying to overlay 2 videos and play sound simultaneously. So far i managed to put 1 video over another using this command :

    


    String[] command = {"-i", mainVideoPath, "-vf",
            "movie=" + overlayVideo + ", scale=300:-1[inner]; [in][inner]overlay=10:10[out]" ,combinedVideoOutput};


    


    and this works but I have 3 problems here.
First, video is rotated by 90 degrees (overlay video), second Audio is played only from main video (I want to play sound from both videos simultaneously), and third overlay video is longer (for example : overlayVideo duration is 10 seconds and main video last 7 seconds) then mainVideo, so i want to final video last as long as mainVideo, as soon as mainVideo finish, overlayVideo should also stop (need to cut it prolly ?)

    


    String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,
            "-filter_complex", "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];[base][wm]overlay=10:10" ,combinedVideoOutput};


    


    Using this command i have 2 problems same as above except video is not rotated here.
I have to say that I'm not very familiar with ffmpeg commands. I was trying to figure it out from documentation link to documentation but without any success.
I know that I'm missing some filters like -map merge or something but can't figure it out.
Thanks in advance !

    EDIT2 :
After adding "-shortest" to command i managed to cut overlay video to be the same length as main video (because overlay video is always longer then mainVideo, "-shortest" take short one duration. So now, command looks like this :

    


        String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,"-filter_complex", 
"[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];[base][wm]overlay=10:10", "-shortest", combinedVideoOutput};


    


    Rotation is good so only need to merge their audios. For now, only mainVideo audio is playing, overlay video audio isn't

    


    EDIT 3 :

    


       String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,
            "-strict", "experimental",
            "-filter_complex",
            "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];" +
                    "[base][wm]overlay=10:10; " +
                    "pan=stereo|c0=2*c0|c1=3*c0[a0];[1:a]pan=stereo|c0=1*c0|c1=4*c0[a1];[a0][a1]amix=inputs=2:duration=first:dropout_transition=2",
            "-shortest" ,combinedVideoOutput};


    


    With this command i managed to overlay videos, and play sound from both of them, rotation is good, but -shortest doesn't work now. Only existing problem now is to make them to last as shorter one (mainVideo is always shorter) ???

    


    EDIT 4 :

    


    This is finally working command

    


            String[] command = {"-i", mainVideoPath, "-i", overlayVideo,
            "-filter_complex",
            "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];" +
                    "[base][wm]overlay=10:10:shortest=1;" +
                    "pan=stereo|c0=2*c0|c1=3*c0[a0];[1:a]pan=stereo|c0=1*c0|c1=4*c0[a1];" +
                    "[a0][a1]amix=inputs=2:duration=first:dropout_transition=2",
            combinedVideoOutput};

  • Errors converting EXRs to mp4 with ffmpeg

    3 février 2021, par GaryO

    I'm using ffmpeg 4.3.1 to convert some EXRs to mp4, with tone mapping for the extended range in the source and rec709 conversion for the mp4.

    


    I'm using this command :

    


    ffmpeg -pattern_type glob  -framerate 24 -i 'frames/*.exr' -vf zscale=transfer=linear,tonemap=hable,zscale=transfer=bt709,format=yuv420p -c:v libx264 -r 24 -preset slow -crf 18 -pix_fmt yuv420p foo-tonemap-01.mp4


    


    but it gives me this error :

    


    Input #0, image2, from 'frames/*.exr':
  Duration: 00:00:00.08, start: 0.000000, bitrate: N/A
    Stream #0:0: Video: exr, gbrapf32le, 1920x1080 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (exr (native) -> h264 (libx264))
code 3074: no path between colorspaces
Error while filtering: Generic error in an external library


    


    What does that error "no path between colorspaces" mean ? Do I need to tell it what colorspace the EXRs are in (scene-linear RGB) or something ?
