I used the following ffmpeg command to generate this:įfmpeg -f image2 -r 10 -i image%05d.png -vcodec h264 -crf 0 -y test.mp4 a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream. The most likely reason is either wrong type (e.g. I have tried encoding using the h.264 codec with crf = 0, but am getting a strange error when I run ffmpeg:Ĭodec AVOption crf (Select the quality for constant quality mode) specified for output file #0 (test.mp4) has not been used for any stream. Here is an image from the video as well as the same section of the original image. png images that I would like to animate into a movie using ffmpeg on macOS, but when I look at the video produced the quality is always compressed and the resulting video has artifacts when the original image does not.
