  • How to speed up sound and video and modify the pitch ?

    3 août 2020, par DiREKT

    I want to increase speed on both the sound and the video, while adding pitch to the audio alone.

    


    I have those two ffmpeg commands, but I don't know how to make them work together.

    


    ffmpeg -i input.mkv -filter_complex "[0:v]setpts=0.94*PTS[v];[0:a]atempo=1.06[a]" -map "[v]" -map "[a]" output.mkv


    


    and

    


    ffmpeg -i input.mkv -filter:a "atempo=1.06,asetrate=44100*1.25" output.mkv


    


  • FFmpeg make video from figures and speed up a chosen part

    11 juin 2020, par user13720066

    Make a video from a series of 100 figures

    



    ffmpeg -framerate 10 -i input_figure%01d.png out.mp4


    



    How can I only make figure numbers from [0-49] with a slower speed like -framerate 5 ?

    



    My try is

    



    ffmpeg -start_number 1 -framerate 5 -i input_figure%01d.png -vframes 49 \
-start_number 50 -framerate 10 -i input_figure%01d.png \
out.mp4 


    



    Doesn't work

    


  • FFMPEG stuck at 00:00:00 speed=0x for a long time at the beginning

    4 juin 2020, par lagmoellertim

    I'm currently writing a script that can remove silence from any video. I'm doing this using ffmpeg and a complex_filter script.

    



    Since most of my videos are pretty long (>1.5h), ffmpeg is called multiple times with a different complex_filter, each editing a part of the video (about 8 minutes long each) and combining those parts at the end.

    



    The input file for all these separate parts is always the original 1.5h video clip.

    



    The problem I keep getting is that for videos starting not directly at the start (first part works fine, second part starting at minute 8 takes longer, third part starting at minute 16 even longer, ... you get the point), this shows up and gets displayed for quite a long time, until it finally works with its normal speed :

    



    frame=    0 fps=0.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x

    



    Here is the ffmpeg script I use

    



    ffmpeg -i video.mp4 -vsync 1 -async 1 -safe 0 -filter_complex_script /path/to/complex_filter -y -map '[vout]' -map '[aout]' video_parts/infb4_3.mp4

    



    I also tried adding -ss 00:24:00 before or behind the -i input, but I did not notice any speed improvement.

    



    And here the complex_filter of one part of the video, starting at minute 24 and ending at minute 32 :
