Use FFMPEG to Merge many frames into one video? -

-

with project working on, taking 1 video, extracting frames within middle, 00:55:00 00:57:25. after extract these images, modifying them via code , need compile these images video. finish off, merge video original video.

ive pulled frames video, modified them, need merge them video.

i used question check format, not getting correct output.

https://superuser.com/questions/563570/use-ffmpeg-for-video-to-frames-then-frames-to-video-with-original-sound

here current input ffmpeg:

-r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj0.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj1.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj2.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj3.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj4.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj5.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj6.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj7.bmp" -r 24.97 -i "c:\users\scott\appdata\local\temp\ios91azj8.bmp" -an -r 24.97 "c:\users\scott\appdata\local\temp\eweljda8.mp4"

edit

my current output gives me video doesn't play. reason, merging of frames isn't correct format , ffmpeg isn't giving me reasonal output work with.

how merge frames video?

there several ways accomplish this. first using pattern merge images incremental video:

ffmpeg -y -start_number 0 -i "c:\users\scott\appdata\local\temp\ios91azj%d.bmp" -c:v libx264 -r 24.97 -pix_fmt yuv420p /media/test/output.mp4

the next, specify individual images in single command:

ffmpeg -y -loop 1 -i img1.png -loop 1 -i img2.png -filter_complex '[0:v] [1:v] concat=n=2:v=1 [v]' -map '[v]' -c:v libx264 -r 24.97 -pix_fmt yuv420p /media/test/output.mp4
