![]() As an output option, it will duplicate or drop frames to achieve the given rate (note that it won’t duplicate frames if output format accepts variable frame rate). r is used here for output (can also be used for input). You can extract frames by defining the amount of frames (per second) you want to extract using -r. -ss: seeks to the given timestamp in the format HH:MM:SSįor most of our requirements, we extract a certain number of frames from a video to ensure a nice spacing between images in a virtual tour.-map: allows you to specify streams inside a file.-pix_fmt: sets the pixel format of the output video, required for some input files and so recommended to always use and set to yuv420p for playback.-r: sets the frame rate of the output video.-vf: sets so called video filters, which allow you to apply transformations on a video like scale for changing the resolution and setdar for setting an aspect ratio.Options include libx264 for H.264, libx265 for H.265/HEVC, and copy if you want to preserve the video codec of the input video.-c:v: sets the video codec you want to use. ![]()
