  1. Hello all,

    I'm new to the forum and working with ffmpeg using windows machine so pls be gentle with me

    My goal is quite simple, I have two video file, one is a clip from a GoPro camera and the other is a video produced by Filmora (video editor), I've tried, without success, to join the two files into one, I got errors trying the Concatenation of files with different codecs, from what i understand the files are not sharing the same codecs/res/and such and should be encoded, following is the ffmpeg -i output for both files(intro.mp4, GOPR2263.MP4:

    Code:

    Can anyone please help me figured out the correct commands to join those two files?

    Many thanks in advance!!
    Best to all,

  2. Try something like:
    ffmpeg -y -i "intro.mp4" -i "GOPR2263.mp4" -filter_complex "[1:v]scale=1280:720[s];[0:v] [0:a] [s] [1:a] concat=n=2:v=1:a=1 [vid] [aud]" -map "[vid]" -map "[aud]" "output.mp4"

    Hi sneaker, thank you very much for your reply!

    I've tried your suggestion but still no joy, I get the error "Conversion failed!":

  4. First file is limited range, second file is full range. I overlooked that.
    Try:
    ffmpeg -y -i "intro.mp4" -i "GOPR2263.mp4" -filter_complex "[1:v]scale=1280:720:in_range=full:out_range=tv[s];[0:v] [0:a] [s] [1:a] concat=n=2:v=1:a=1 [vid] [aud]" -map "[vid]" -map "[aud]" "output.mp4"

    or if AR is different:
    ffmpeg -y -i "intro.mp4" -i "GOPR2263.mp4" -filter_complex "[1:v]scale=1280:720:in_range=full:out_range=tv[s];[s]setsar=1:1[so];[0:v] [0:a] [so] [1:a] concat=n=2:v=1:a=1 [vid] [aud]" -map "[vid]" -map "[aud]" "output.mp4"
