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: 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.
