  • How do I speed up a video to a specific time for instance 'n' seconds in FFMPEG ?

    24 novembre 2022, par user3475182

    When using python moviepy library, you can speedup a video to a specific time using the below command :

    


    video.fx(vfx.speedx, final_duration=audio_duration)


    


    Is there a way we can achieve the same using ffmpeg ?

    


    I tried the below commands ; but this will not accurately speed up the video to a specific time.

    


    ffmpeg =i input.mp4 -filter_complex "[0:v]setpts=0.5*PTS[v];[0:a]asettps=0.5*PTS[a]" -map "[v]" -map "[a]" output.mp4


    


  • Handbreak ffmpeg encode vs decode speed (x265)

    10 février 2023, par Demian

    I'm encoding videos in x265 to save same storage (Gopro, DJI, etc.). This is working well for me with Handbreak and I got some good CRF values for my use cases.

    


    My question is about the encoding preset. The slower it is the better Qualitiy per Bitrate you get, but the encoding time increases.

    


    But how the decoding time. Does it also consume more CPU power to watch (decode) a video which was created with a slow prestet then a fast preset ?

    


    Thank you !
