I am trying to export a file from InDesign for work. We send out daily email with PDFs from InDesign and would like to include from training videos. How can we include the MP4 format video so we can watch them in the PDF we send out. I've read through the Interactive PDF guides and forums. A still image of the first frame of the video appears, we can't get it to play.
Better is, to put the videos on the web and provide the PDFs with links to that video, otherwise the size would increase and cause problems to your recipients.
While including an MP4 video is good if you know the recipient is using Acrobat/Reader on a desktop computer, the content may or may not work on a tablet or smartphone. I'd go with Wilhelm's suggestion of providing a link.
