• FFMPEG images to video + overlay video

  7 novembre 2018, par AK47

  I am trying to make 15 second video where the background layer is a video made up of 2 images, the first line creates a 15 second video from 2 images.

  I chose a small framerate so it renders an mp4 quickly. I then overlay a webm video (which has transparency) over the images. The final video seems to keep the framerate of 2, but i would rather keep the 24 framerate of the webm video.

  Is this possible ? & is it also possible to turn the below into 1 statement.

  ffmpeg -loop 1 -framerate 2 -t 11 -i image1.png -loop 1 -framerate 2 -t 4 -i image2.png -filter_complex "[0][1]concat=n=2" backgroundvideo.mp4;
  
  ffmpeg -i backgroundvideo.mp4 -c:v libvpx-vp9 -i overlayvideo.webm -filter_complex overlay newvid.mp4

• FFMPEG Overlay 1080X1920 video over 1280X720 video at a particular vertical position

  9 mai 2019, par CRAIG

  I have a 1080X1920 (vertical) video with alpha channel with a blank spot 500px north of the bottom. This blank spot is 1080X607.

  I have a 1280X720 sized video I want to position in that spot, so the 1280 video will have to be sized down to 1080 wide and then positioned 500px from the bottom and UNDER the video on top.

  This is what I currently have, but it is failing beautifully.

  /usr/local/bin/ffmpeg  -i 1080x1920.mov -i 1280x720.MOV 
  
    -filter_complex "[1][0]overlay=main_w-overlay_w-0:main_h-overlay_h-500" 
  
    -c:v libx264 -profile:v high444 -pix_fmt yuv420p -level 3.1 -y  final.mp4

• Crop layout for Videos using touch for a Video Editor like Video Show or Filmora Go in android studio [closed]

  26 août 2020, par Rayhan Khan

  I am new to the android studio (Java) and video editing application. I am developing a video editor in android studio with FFMpeg Library.

  


  I want to create a crop layout with a rectangle layer on top of it to measure the details like :

  


  

crop video width : 900
crop video height : 500
left distance (x value) : 190
top distance (y value) : 110

                                    1280
