![]() Sometimes you might have to convert that video from. If that video is on YouTube, use a DownloadHelper to download that video. You can then play the video and explain what happens unencumbered by having to show it as well. Quicktime can do screen recordings (albeit without sound). If you need to show them the website with the video, create a video of you using that website and show this video. And while you could use cellular data for individual websites, downloading a video via a cellphone connection is tedious at best. You can control a lot during a presentation, but Internet access is usually outside your control. If not, there is usually a “Rehearse slideshow” option (in Keynote, look under “Play”). If you have an external display, that’s usually the easiest way to go. You should rehearse your presentation in any case. If the embedded video does not start, open the video in an external player. So keep a file without the embedded videos. If this happens with keynote, see this posting. However, sometimes there are issues with videos when you move to another computer. This makes it easier to transfer the presentation to another computer - everything is included and you do not need to be careful about file links. You can usually embed the videos (= copy them into the file). ![]() Embed the videos, but keep a version without the videos.During the presentation you might not remember the content well enough, or the crucial parts of it. Use the notes field of the slides to write down the keywords for a short recap of the video. You also might be using another computer which cannot play that particular kind of video. Some programs behave rather strangely (see above). Don’t rely on the videos in your presentation.The file size should have been a dead giveaway, but I missed it. Well, I think it was an important information. PowerPoint did not even inform me about it. Last week, I was forced to use PowerPoint and found out that a compatibility mode converted my videos into images (saved the presentation as. Don’t trust PowerPoint - close, reopen and check it again.If it’s shortly before a presentation, always chose later. It does not show you what will be updated and only gives you the choices between “do it now” or “try later”. I really hate Mavericks for its update dialogue. Apple I am talking to you about your Keynote update! So, avoid doing updates prior to the presentation. If you have tested it and it worked, it will likely work during the actual presentation as well. Given that the computer you are using might miss some codecs, use your own computer. If in any way possible, use your own computer for the presentation.MPEG Streamclip handles the video conversion for me (Mac and Windows program). ![]() Convert the videos in a widely supported format. ![]() So, if you use videos in your presentations, here are a couple of tips: If your computer cannot understand this video or audio codec or does not recognize the file ending, you’ve got a problem. flv), using different codecs for the video image (e.g., H.264) and for the audio (e.g., MPEG 4 audio, Apple Lossless). Videos can have different file endings (e.g. In part I think it’s due to the confusing number of video formats, and audio and video codecs. But still, I wonder why - in 2014 - videos in presentations are still such an issue. I think the only thing that really impressed me in her presentation was with how much confidence she reacted to these “mishaps”. Especially given that this is just the craft of presentation, nothing more. I don’t mind people researching what they do not know, but I think that when they are doing a presentation, they should have mastered it at least a little. Perhaps it’s because she works with videos that I would have expected more … competence. A website with an embedded video that stopped in mid-play. Her presentation included a couple of videos. She was the head of a department developing video tools. Little Red Riding Hoods Father and Little Red Riding Hood, about the paw of a wolf that turned into a human hand, in “The Company of Wolves”Ī while ago I watched a presentation by professor working within the domain of educational technology.
