Ffmpeg：如何将视频大小调整为 1080x607

Question

我需要将视频尺寸从 1920x1080 调整为 1080x607，以便用于 Instagram。我试过

ffmpeg -i input.mp4 -vf scale=1080:607 output.mp4

但

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height ```
