Why don't *you* show us *your* exact command's output? That is much more helpful than just having liks to two other cases which seem "related". > printf "file '%s'\n" ./*.png > test_ffmpeg.list > ffmpeg \ > -f concat -i test_ffmpeg.list \ > -r 30 -pix_fmt yuv420p \ > -c:v libx264 -preset slow \ > Muybridge_race_horse_animated.mp4 I have no explanation for the DTS errors, but I can make your command work. :-) You're doing one thing quite wrong: You are creating a concat stream which defaults to 25 fps, and then converting it to an output of 30 fps. If I switch your "-r" option to become an input option, I still get the DTS warnings, but an output video which seems totally sane (15 frames, 30 fps, 0.5 s length). This is probably what you intended to do. > Am I doing something wrong or is there a bug? Both, perhaps.
