I have extracted all frames from an old video file, cleaned up video tape dropouts and film scratches frame by frame.
I now must reassemble the PNG files into a video .
and modified what I found there to:
ffmpeg -r 1/5 -start_number 0 -i buggles%4d.png -c:v libx264 -vf "fps=25,format=yuv420p" out2.mp4
I have available only the first 500 frames @25 frames per second and am testing with that. It should yield a 20 second video
Instead I get a video of 41:35 in length that changes frames about every second and VLC reports 25 FPS.
Maybe I need to define that each image is on screen for only a single frame, but how?
