  • FFMPEG cut out group of frames

    20 juin 2019, par Virgosh

    I’m looking for a command to cut out exact frames from a video.

    I know that I can do this by slicing the video in two and then concat,
    but I’m looking for a sigle command to achive the same result,
    something like :

    ffmpeg -i video.mov -cutframe 1239 video_cut.mov

    or something like

    ffmpeg -ss 2348 -i video.mov -tt 2349 video_cut.mov

  • Revision 691ec45b4e : Enable group adaptive max q by default. Set the GF group adaptive max Q compile

    23 mars 2015, par paulwilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_firstpass.c



    Enable group adaptive max q by default.

    Set the GF group adaptive max Q compile flag to 1 by default.

    This change has a quite big visual impact in some clips and also
    contributes to tighter rate control.

    For short test clips that have consistent content the impact is
    quite small on metrics but for more varied long form clips there is
    a drop in overal psnr but a sharp rise in average psnr caused by
    greater expenditure on some easier sections and tighter rate clipping
    in hard sections.

    In chunck’ed encodes some of the effect will already be present due
    to the independent rate control in each chunk but this change takes
    the control down to a smaller scale.

    yt hd +10.67%, - 3.77%, -1.56%
    yt +9.654%, - 3.6%, - 1.82%
    std hd +0.25%, -0.85%, -0.42%
    derf +0.25%, - 1.1%. - 0.87%

  • Discard images from a group of similar images

    31 mai 2018, par Saah

    I am generating images (thumbnails) from a video every 3 seconds. Now I need to discard/remove all the similar images. Is there a way I could this ?

    I generate thumbnails using FFMPEG. I read about various image-diff solutions like given in this SO post, but I do not want to do this manually. How and what parameters should be considered that could tell if a particular image is similar to other images present.
