  • How do you combine videos at specific X and Y positions with FFMPEG ?

    21 mai 2020, par Adrian Elder

    If I have multiple video files, and I want to combine videos at specific x/y coordinates, how would I go about doing that ?

    



    I know that the xstack filter allows you to position videos using a column/row notation.

    



    Say I have multiple different size rectangle frames, and I knew the x/y coordinate of the top left corner, how could I position these using that value ?

  • Concatenating different rotated videos with ffmpeg

    14 avril 2017, par acilander

    I am trying to concatenate two videos with ffmpeg having different rotation metadata tags. The first one has rotation=180 the other one has no tag at all.

    There are two methods that can be used in ffmpeg : concat demuxer / concat protocol. Protocol is working as expected but demuxer method is not. When I use concat demuxer option in ffmpeg with copy option to avoid re-encoding the following happens :

    First video with rotation = 180 will be rotated correctly. But the second video without rotation flag will also be rotated and will be presented upside down in output video.

    I know about the options to remove rotation metadata or the possiblility to use filters to rotate the videos. But my question is if someone knows if this is expected behaviour of ffmpeg or not. For me it seems like ffmpeg uses rotation metadata from first video and uses it for all other concatenated videos. Is this assumption correct and intended ?

    Thank you for any feedback and explanations.

  • Contrast normalization of several videos with ffmpeg

    4 octobre 2016, par Alan_AI

    I have some video sequences that I need to concatenate, some of them have bad contrast (so dark) and some are just fine. What is the best method to automatically normalize contrast levels among of these videos automatically without manual tweaking ? Preferably using the ffmpeg script

    Thank you
