  • FFMPEG How to merge several videos to one file with fade effect ?

    10 juin 2016, par user2455079

    Need to merge several videos to one (for example 5 videos) with simple fade transition (video length various from file to file) if resolution is larger than 1280x720 must be resized proportionally and add sound track mp3 file to whole video. (Video files doesn’t contain audio)

    Only found this solution :

    But uses static file length in parameters...

  • Join videos without interruption with removing extra scenes automatically

    19 janvier 2014, par RarLines

    I've tens of splitted videos from a video.

    My english is poor so I will try explain with a simple example :

    The original video scenes like so: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14

    But I had never the original video. I've these videos :

    Video_1.part scenes: 1, 2, 3, 4, 5
    
Video_2.part scenes: 5, 6, 7, 8, 9 (5 is extra !)
    
Video_3.part scenes: 9, 10, 11, 12, 13, 14 (9 is extra !)

    When I try to concatenate (or join, merge, combine...etc) these videos with using ffmpeg, the scenes the output file are liked that :

    The output video scenes: 1, 2, 3, 4, 5, 5, 6, 7, 8, 9, 9, 10, 11, 12, 13, 14

    As you can see, when I watch the output video there are interruptions between videos.

    Is there any technical way to join videos without interruption (or nonstop, continuous...etc) ?

    Please note that, my example is so simple. I'm not sure that the splitted videos have regularly extra scenes. If I was sure, I could crop equally. Maybe the length of extra scenes are equal. But I couldn't check.

    Hope you will show an intelligent method. Thanks

  • Some transcoded videos get frozen in the middle

    20 juin 2018, par corolok

    OS : ubuntu 16.04
    ffmpeg : 3.4.2-1

    Here are ffmpeg parameters :

    ffmpeg -y -i raw.mp4 -threads 2 -r 25 -profile:v baseline -preset veryfast -s 1280x720 -aspect 1.7777777777777777 test.mp4

    Most of the videos are good but sometimes we get videos which stop playing somewhere in the middle (audio is ok, but video doesn’t play anymore)

    Can it be related to performance ? There are 8 cpu cores and 2-4 ffmpeg processes can be run at once, metrics show that CPU load is always below 60% so it shouldn’t be the case I think.
