how to use ffmpeg to create video from images

To create a poster image at a specific time instead of at the beginning of the video, add -ss parameter with value in seconds ffmpeg -ss 1.4 -i video.mp4 -frames:v 1 video-poster. ffmpeg will also handle image conversion.

The last parameter is the output file name video-poster.png.

:v is a Stream specifier to tell ffmpeg that we are working with a video file.

-frames:v 1 stops working after the 1st frame (because we need only 1 frame).The command generates the files named image1.jpg, image2.jpg and so on ffmpeg -i video.flv imaged. This will create a PNG image that has the same width and height of the video file. To turn a video to number of images, run the command below. ffmpeg -i video.mp4 -frames:v 1 video-poster.png When the video file finishes loading and starts playing, there will be a smooth transition from the poster image to the video.Ĭreating a poster image from an mp4 file can be done with ffmpeg command line tool. I will use the first frame of the video file as a poster image. This gives a hint to the user that there’s some content there. The poster image will display while the video file is loading. I wanted a quick way to create a poster image from a video file (mp4) to use with poster attribute of the element.

I’m working on a website that has a few short animations in elements on the page.
