  • ffmpeg fastest way to convert videos avi to mp4 [migrated]

    5 novembre 2013, par user2938660

    I have server which has :

    • 8x3,4 (sandy bridge cpu)
    • 10gb ram

    i tried different combinations to convert vvideos i mean avi to mp4 but it takes so long :
    - 20mins= 200mb

    maybe there is some ffmpeg command which does this much faster ?

    EDIT WITH ULTRAFAST :

  • FFmpeg converting image sequence to video results in blank video [closed]

    11 septembre 2016, par Brandon Durham

    I’ve got a series of 361 .png files that I’m trying to convert to video, and for whatever reason the resulting video is just black. Here is the FFmpeg code I’m using :

    ffmpeg -f image2 -i "FeatureTour_%05d.png" -r 30 -vcodec libx264 -b:v 9600k "FeatureTour.mp4"

    The files are formatted correctly (FeatureTour_00001.png) and no errors are thrown. It just results in a 160kb mp4 files that’s black.

    Any idea what I’m doing wrong ?

    EDIT

    Here is my output after using the above code :
