Xfade=transition=slideleft:duration=0.5:offset=5 \ "xfade=transition=slideleft:duration=0.5:offset=2.5 \ Whereas with the above two techniques your inputs don't really have to be the same size (ffmpeg will simply crop according to the size of your first input) when using xfade your inputs must all be of the same resolution. Xfade is a lot more fussy about its inputs. fade=d=1:t=in:alpha=1,setpts=PTS-STARTPTS+2/TB fading in with a duration of 1 second, applying an offset of N seconds.įFmpeg also comes with a range of transitions you can use via the xfade filter.įor example, this is a slideshow using a transition called slideleft:.-loop 1 -t 3 -i img001.jpg importing an image with a duration of 3 seconds, and telling FFmpeg to loop the input.Overlay,format=yuv420p" -map "" -r 25 output-crossfade.mp4 This command achieves the crossfade effect: ffmpeg \ There are a couple of different ways to achieve this, but perhaps the easiest to grok is where you import each image as a separate input and then fade them in as overlays on top of each other, one after another. This is a slideshow with a crossfade effect from one image to another: -i img%03d.jpg the image sequence to import.A framerate of 1/3 means that FFmpeg will display each image for 3 seconds. -framerate 1/3 specifies at what speed FFmpeg should import the images.Then simply run this command: ffmpeg -framerate 1/3 -i img%03d.jpg -r 25 -c:v libx264 -pix_fmt yuv420p output.mp4 The simplest way to achieve this is to first organize your images with a specific naming convention, and in the same folder: This is a slideshow with no transitions, that simply jump-cuts from one image to another: Here's how to create a simple slideshow from images with FFmpeg. FFmpeg is an incredibly powerful tool you can use for generating videos, even from static content like plain old images.
