  • ffmpeg, how to cut to exactly at the start and end time ? [closed]

    28 mars 2024, par Wayne Julian

    According to this article you can only cut the time, but not specify when to cut from the original video. So the end time will always be wrong. You need to calculate each time on the timeline when your video will end.

    


    e.g. -ss 01:30:40 -to 03:03:05 will cut your video in the wrong order, because it starting the calculation not from the 00:00:00 of the video, but from the -ss 01:30:40

    


    Is there a workaround for this ?

    


    example command :
ffmpeg -ss 00:14:15 -an -i  "2022-05-30.mp4" -to 01:30:40 -crf 23 -c:v libx264 PART1.mp4

    


    I will lose 14:15 minutes here, it is clearly a bug.
I need to extract 14:15 from the end time to get the correct time of the result video. When it comes to multiple video-editing it's so annoying.

    


  • FFmpeg video thumbnail colors look off (dull, faded, desaturated)

    21 juin 2022, par schneikai

    I try to generate video thumbnails with FFmpeg but the colors of the generated JPG file look very different from the video. Here is a screenshot I took while running the video in a player and the other picture is a JPG generated with FFmpeg. The video was recorded with an iPhone 12.

    Here´s a link to the mov-file : https://www.dropbox.com/s/udowplvfspxq6ag/IMG_8357.MOV?dl=1

    


    I use the following FFmpeg options : -y -vframes 1 -f image2
