Image sequence of 1500 frames to loop 30 times in a 30 min video FFMPEG

Question

Really struggling to get this to work, I just need to loop an image sequence. It is 25fps and exactly one second in duration (1500) I need this to basically loop for 30 mins, so it will loop 30 times. Using FFMPEG, here is the working 1500 frames being converted to MP4, like i said it has to be 30 mins in length:

ffmpeg -i "input_%04d.jpg" -c:v libx264 -b:v 1M -s 1080x810 -crf 28 -r 25 -pix_fmt yuv420p out.mp4

Answer 1

Use -loop 1 as an input option for an infinite loop, and then use -t 00:30:00 as an output option to cut off the video at thirty minutes. I would also suggest that you have a look at the H.264 Encoding Guide, and the FFmpeg wiki in general.

ffmpeg -loop 1 -i "input_%04d.jpg" -c:v libx264 -s 1080x810 -preset veryfast -crf 28 -r 25 -pix_fmt yuv420p -t 00:30:00 out.mp4
