• Video with music taking long time

  1er octobre 2020, par Konduri Sai Aditya

  Hi I am rendering video with filters and adding audio at the end. But while running it is taking a long time and rendering continuously. Can anyone help me where I am wrong ? below is the command

  


   ffmpeg -i test.png -i test.mp4 -i test.mp3  -y -filter_complex "[1:v]scale=1422:800[scale1],[scale1]rotate=0:c=black@0:ow=rotw(0):oh=roth(0)[rotate0],[0:v][rotate0]overlay=258.04:107.71[mediaoverlayout0],color=black@0:451x137[c1],[c1]setsar=1,drawtext=fontfile='/Windows/fonts/Peddana-Regular.ttf':text='ADITYA':fontsize=121.199:fontcolor=#1e8bc3:line_spacing=16.91,rotate=0:ow=rotw(0):oh=roth(0):c=black@0[rottext1],[mediaoverlayout0][rottext1]overlay=x=544.63:y=263.076[out]" -vcodec libx264 -map "[out]" -map 2:a -preset veryfast -c:a copy -pix_fmt yuv420p op.mp4 


  


• ffmpeg concat image with video, but output extra long

  11 octobre 2020, par Morris

  My goal : To concat an image (foo.jpg) with a video (bar.mp4, 3 seconds long). Show foo.jpg for 2 seconds only. Output video should be just around 5 seconds long.

  


  I used :

  


  ffmpeg -loop 1 -t 2 -framerate 1 -i foo.jpg -f lavfi -t 2 -i anullsrc -i bar.mp4 -filter_complex "[0][1][2:v][2:a] concat=n=2:v=1:a=1 [vpre][a];[vpre]fps=24,scale=32:24[v]" -map "[v]" -map "[a]" out.mp4


  


  I think the command means :
Loop foo.jpg for 2 seconds at framerate of 1 frame per second. At the same time, add silent audio track to the 2-second foo.jpg video.
Then concat with bar.mp4.
Make final output framerate 24 fps. Scale it to 32x24 dimension (intentionally tiny for testing).

  


  Expected : output to be about 5 seconds long in total.

  


  Reality : output is 3 minutes and 38 seconds long. The first 5 seconds is perfect. After that, video just stays silent with the 5th-second frame frozen until the end.

  


  My research shows that it might be related to -video_track_timescale

  


  This command also fails with same over-long result (I added -video_track_timescale 600) :

  


  ffmpeg -loop 1 -t 2 -framerate 1 -i foo.jpg  -f lavfi -t 2 -i anullsrc -i bar.mp4 -filter_complex "[0][1][2:v][2:a] concat=n=2:v=1:a=1 [vpre][a];[vpre]fps=24,scale=32:24[v]" -map "[v]" -map "[a]" -video_track_timescale 600 out.mp4
