Insert a video
If you have recorded a video using your phone, its size might be small enough so that you can attach it directly to the page. If so, attach your video and write Unable to render embedded object: File (videoname.mpg4) not found. in "Wiki Markup" mode where you want it to appear.
If the video is long and would take long for the user to open the page you would have attached it to, upload your video to YouTube. Copy the object tag that YouTube allows you to embed (look for "embed" on the page presenting the video). When editing your TransActions page, switch to "Wiki markup" mode
and paste the object tag where you want the video to appear on your page.
