You can use this technique to overlay multiple files on top of each other, or even have a dynamic overlay. The offset is specified as overlay=x:y where x is the x offset in pixels and y is the y offset in pixels overlay=0:0 specifies the position of the overlay, in this case the overlay image is assumed to be the same size as the video so no offset is needed.joins the two video streams together, stream 1 is the set of images, stream 2 is the overlay file.~/path_to_overlay.png is the full/relative path to the overlay image.ffmpeg -r 60 -f image2 -s 1920x1080 -i pic%04d.png -i ~/path_to_overlay.png -filter_complex " overlay=0:0" -vcodec libx264 -crf 25 -pix_fmt yuv420p test_overlay.mp4 -vframes 1000 specifies the number frames/images in the videoĪssuming that you have an overlay image that is the same size as the video, you can use the following command to add it during the ffmpeg compression process.-start_number specifies what image to start at.The file will be output (in this case) to: test.mp4 Specifying start and end framesįfmpeg -r 60 -f image2 -s 1920x1080 -start_number 1 -i pic%04d.png -vframes 1000 -vcodec libx264 -crf 25 -pix_fmt yuv420p test.mp4 -pix_fmt yuv420p specifies the pixel format, change this as needed.-crf is the quality, lower means better quality, 15-25 is usually good.If no padding is needed use something similar to pic%d.png or %d.png. Where the %04d means that zeros will be padded until the length of the string is 4 i.e 0001… 0020… 0030… 2000 and so on. etc) use the following command: ffmpeg -r 60 -f image2 -s 1920x1080 -i pic%04d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p test.mp4 To take a list of images that are padded with zeros ( pic0001.png, pic0002.png…. I have noticed that different versions of ffmpeg will produce different output file sizes, so your mileage may vary.
