  • FFMPEG multiple styles in .srt file

    7 décembre 2020, par Tim

    I have an SRT file and want to change the background color and level of transparency for individual tracks. Is this possible, or would I have to adopt a more advanced format ? Would this task even work in FFMPEG ?

  • Remapping multiple Mp4 videos into a single one with ffmpeg

    21 septembre 2016, par Josep Bosch

    I’m interested in remapping multiple (6) MP4 videos into a high resolution final video according to lookup tables I calculated. The idea is convert 6 independent videos in a 360º video according to an equirectangular projection.

    Equirectangular image example
    Example of equirectangular video here

    Is there a way to do this remapping with ffmpeg or any other linux program ?
    Right now I’m extracting all the frames from the videos, creating the equirectangular individual images and joining them again into a video. There must be a better way for this...

    UPDATE :

    Following Mulyva’s suggestion I first remap each individual video using the remap filter. Those parts of the panoramic video not covered are interpreted like chromakey pixels using :

    ffmpeg -i videos/camera1.MP4 -i camera0_map_x_radius5.pgm -i camera0_map_y_radius5.pgm -lavfi remap -qscale 1 out0.MP4

    Camera0

    Camera1

    Then I try to overlay them using the chomakey filter :

     ffmpeg -i out0.MP4 -i out1.MP4 -filter_complex "[1:v]chromakey=0x12da11:0.2:0.2[chromakey_res];[0:v][chromakey_res]overlay=eof_action=pass[out]" -map "[out]" out.mp4

    As you can see, the final result has an undesirable green shadow. Any idea of how to remove it ?

  • Need help concatenating multiple 2 part .mp4s

    9 septembre 2016, par Jay Ford7

    Basically, I have about 200 2-part videos that I would like to concatenate as 100 individual files.

    All the files are labeled with the same file name but with part 1 and part 2 on the end, ie "Video Name Part 1...Video Name Part 2"

    Through basic searching I understand how to combine two videos into one video manually with ffmpeg, but is there a way for ffmpeg to recognize the naming structure and do a batch concatenation ?

    EDIT : I should’ve said I was on Windows !

    Thanks !
