• make video from image file using ffmpeg

  4 août 2014, par Roylisto Putra Pradana

  i have 64 images sequence and i want to make a video using that images.

  you can download the images here

  i use ffmpeg in ubuntu.
  here’s my command

  ffmpeg -r 60 -f image2 -s 1360x768 -i "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/tmp/result%d.png" -vcodec libx264 -crf 20 "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/render/test.mp4"

  it works but only 39 images has generated to a video. My question is why ffmpeg not render all images in that folder into a video, what is my mistake and how to solve it ?

  Output Command :

• I tried to make an avi file from images using ffmpeg but the avi file is very small why ?

  13 mai 2013, par Yaron Cohen Minz

  I tried this :

  In C# i'm creating 100 bitmap files :

  for (int i = 0; i < 100; i++)
  
              {
  
  
  
                  t.Save(@"D:\ffmpegtorun\ffmpeg-20130509-git-13cb6ed-win32-static\bin\Screenshots\" + "Screenshot" + i.ToString("D6") + ".Bmp",ImageFormat.Bmp);
  
              }

  Then i'm using the ffmpeg.exe command line to create an avi file movie of all the bitmaps.

  D :\ffmpegtorun\ffmpeg-20130509-git-13cb6ed-win32-static\bin\Screenshots>ffmpeg -
  f image2 -r 5 -i Screenshot000099.bmp -c:v libx264 -r 30 out.mp4

  And before it i tried :

  D :\ffmpegtorun\ffmpeg-20130509-git-13cb6ed-win32-static\bin\Screenshots>ffmpeg -
  f image2 -r 1/5 -i Screenshot000099.bmp -c:v libx264 -r 30 out.mp4

  When i tried to use jpg files i got an error say jpeg is not supported.
  Then when the files were 1920X1080 i got an error say this resolution is not supported.

  Now i did it again and hot this :

  D:\ffmpegtorun\ffmpeg-20130509-git-13cb6ed-win32-static\bin\Screenshots>ffmpeg -
  
  f image2 -r 1/5 -i Screenshot000099.bmp -c:v libx264 -r 30 out.mp4

• Where can I find my output video file after execution of ffmpeg command

  7 août 2019, par Giri Aakula

  I run this command to capture my screen

  ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4

  I didn’t find the output.mp4 file anywhere in my HDD. I checked in the bin folder of ffmpeg it is not there.
  I searched the whole PC I didn’t find it anywhere. Can anyone please help me out to find the file.
  The console output is
