• Why is the length of the output video increasing when I overlay an image over a video using ffmpeg ?

  24 août 2020, par Farhan

  ffmpeg -i somevideo.mp4 -i someimage.png -filter_complex "[0:v][1:v] overlay=10:10:enable='between(t,2,4)'" output.mp4


  


  In this case, somevideo.mp4 is a 4 second video. I wanted the last 2 seconds to have the overlay of the someimage.png image. After processing, the length of output.mp4 is 5 seconds. Could someone please help me out on this ? Thank you !

  


  Log for ffprobe of output.mp4

• Unable to find suitable output format for 'ffmpeg'

  23 mai 2023, par kumarvhat

  I'm trying to use the ffmpeg toolset to stitch a set of images to an .mp4 and am receiving the following error :

  


  [NULL @ 000001d48d1dcc00] Unable to find a suitable output format for 
'ffmpeg' ffmpeg: Invalid argument


  


  The command I'm using is :

  


  ffmpeg -r 30 -f image2 -s 1920x1080 -i C://MYPATH//back_squat_%03d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p C://MYPATH//back_squat.mp4


  


  And the full output looks like this.

  What is wrong with the syntax of the command string ?
