![]() "concat=n=3:v=1:a=1" Better for distributionĪnd with this I can have a call to action in the final slide, as well as in the video description because there is no guarantee that people actually read the video descriptions. If I wanted more videos I would add them as -i anothervid.mp4 and I would have to change the filter complex definitionĮ.g. ![]() ![]() Since enough has changed regarding installation and use, I figure a new, spiffy, and working. I return to it on occasion and have updated my gist comment to offer some updated commands. Way back in Dec 2015, maxogden wrote a nice guide on stabilizing your own video with ffmpeg. I can join any number of videos together, but in this case I’m just combining two: ffmpeg -i video.mp4 -i promo-image.mp4 Video Stabilization With ffmpeg and VidStab. i anullsrc=channel_layout=stereo:sample_rate=44100 I found that when concatenating the videos, I needed to add a silent audio track otherwise the videos would not concatenate, so the following is the command I used to create my post roll video. It doesn’t matter what size the image was previously, the video will be 1920 x 1080 pixels. I will want to control the size of the video so that when I join them they are the same dimensions, I can do that in a single command. This will create a video called ‘promo-image.mp4’ with a duration of 5 seconds. Remember when you type it in, all lines will be on a single line. I can create a 5 second video from a png as follows: ffmpeg -r 10 -f image2 -i d.jpeg output1.mp4 The command as above will stitch 10 images per second, 250 images will eventually generate 25 seconds of video. I could create a video for that, but to make it easier to change I’m going to use a single image that displays for a few seconds. Ideally I want a post roll video which links to my site. I now know how to create videos for various sites. Previous posts have covered ffmpeg for helping with video marketing. Having created a video, I want a call to action image that plays after the video is complete, and I want this to be standardised for a lot of my videos.
