  • How do I use ffmpeg to extract frames starting at a specific number ?

    19 octobre 2020, par Gridzbi Spudvetch

    I've decided for some reason to upscale an entire 90-minute movie using AI. Problem is, I have several demo scenes that have already been upscaled, and I want to keep those frames rather than upscaling them again. Basically I want to export frames starting at a specific number, like ffmpeg -i scene1.mp4 scene1/%10d+[starting number].jpg. If the specified number were 1550, for example, the first frame it would export would be 0000001550.jpg. I still want it to start at the first frame of the input video, though ; the only things I want to change are the names of the output files. Is there a way to do this ?

    


  • Frame Number Overlay With FFmpeg syntax

    6 juillet 2020, par DougM

    This has been covered before, and the consensus solution is (minor variations on) the following command line :

    


    ffmpeg -i input.MP4 -vf "drawtext=fontfile=Arial.ttf:text='%{frame_num}':r=25:x=(w-tw)/2:y=h-(2*lh):fontcolor=white:fontsize=50:" -c:a copy output.mp4


    


    Unfortunately, when I apply this to my MP4 files the text that gets placed is "r=25". I've tried every variation that I can think of, but none of them result in a frame number displayed that correlates to the frames.

    


    I know that it is aware of frame numbers because as it runs in the command line it displays the frame number that it's working on :

    


    . . .
frame= 132 fps= 13 q=-1.0 Lsize= 1040kB time=00:00:01.07 bitrate=7913.9kbits/s speed=0.11x
. . .

    


    Can you please help me with the correct syntax for placing the frame number in the video ?
