My approach with that would be to create a 5 second video from the image (using something like "ffmpeg -loop 1 -framerate 29.97 -i <image> -c:v h264 -pix_fmt yuv420p out.mp4" then concatenate them using the concat input. Assuming matching codecs and resolution, this would work well without having to transcode the whole video. You might also need to add an empty audio track to the 5s segment beforehand though. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
