Hello, I hope someone can help me out here, would really appreciate it :).
I created a video out of images, and then merged it with other videos. The problem is that the final result is kinda broken - when I want to add background music to it, it won't play the music on the parts with the video generated by images, and on mobile phones it seems even more broken. The commands I used: Extracting the images from the video: ffmpeg.exe -i E:\dev\chatgpt\temp11\peng\final\1_runway.mp4 -vsync 0 -f image2 E:\dev\chatgpt\temp9\peng\final/1_runway-%06d.png Then I edit the images, then merging them back with: ffmpeg.exe -i E:\dev\chatgpt\temp11\peng\final\2_runway_final-%06d.png E:\dev\chatgpt\temp9\peng\final\5_runway_final.mp4 This file now seems to be broken Now when i merge this file with other mp4s via ffmpeg.exe -f concat -i E:\dev\chatgpt\temp11\peng\\final\ENGLISH_ffmpeg_input.txt -vcodec copy -acodec copy E:\dev\chatgpt\temp9\peng\\final\ENGLISH_output.mp4 Ad then add background music via ffmpeg.exe -i "E:\dev\chatgpt\temp11\peng\final\ENGLISH_output.mp4" -i "E:\dev\chatgpt\background.mp3" -filter_complex "[1:a]volume=0.2[a1];[0:a][a1]amix=inputs=2:duration=longest[a]" -map 0:v -map "[a]" -c:v copy -c:a aac -shortest "E:\dev\chatgpt\temp10\peng\final\ENGLISH_output_background.mp4" the background music isn't played in the parts with the "video generated from images". Even VLC sometimes have problem displaying all parts correctly - that's why I added Youtube-links - this seems to work somehow. Does anyone have a clue how I can investigate further? Thanks in advance!
