If you prefer to avoid working with the configuration of the video yourself, you might prefer to use a service such as Youtube to upload and put your video online. MPEG4 (mp4) has become a more popular video format because it has fewer compatibility issues than FLV format. We are likely to see less and less 4:3 video as time goes on. ![]() A 4:3 ratio is more square and can be effective for filming a single person talking. A higher quality and larger 16:9 size is 1280x720 this is also the preferred size used for high quality (HD) on Youtube.Ī 16:9 ratio is wider than 4:3and can be useful for filming a scene with several people, for instance a student play. Our example above is 320x240.Ī second popular aspect ratio is 16:9. ![]() If you change the video size (resolution), you should be careful to keep to the same aspect ratio. Two common formats for digital video match the standard sizes for television video.ģ20x240, 512x384, 640x480 (in pixels) are all 4:3 aspect ratio in other words, the ratio of width to height is always 4 to 3. If you do not know the size (resolution) of your video, right click on it to see the details of its properties. Your original video will have a certain dimension (width & height) and will be in some video format (mov, avi, flv, mp4, etc.). It is also a good idea to use compression and consider the size (resolution) of your video. If you prepare a video to use in a lesson with your students, whether the video is created with a digital camera, a digital video camera, or some other source, it will be easiest for you to create materials consistently if you are used to using a single format for your video. You can download the video sample here to practice converting if you don't have a video of your own. A better solution that gives you more control is to use mp4 video format with a player that is built into the page, downloaded from your own web site, and is more compatible with various operating systems and web browsers. In the sample to the left, this video requires the Windows Media Player plug-in.Īlthough this works in most cases, you, as the web page designer, have no control over whether it will work on your user's computer. The video is in wmv format and has the file name: webcam-vid-2.wmv. We will use a video from a previous lesson as an example. We will explore using free software to convert your video to mp4 format and prepare it for online playing from your own site.įor this lesson, we will suppose that you already have a video in some format that you wish to put on a page. Your Youtube based video could then be embedded on your web page. One option might be to use Youtube to make your video available. With these programs your final video is in the WMV format, but no matter what format you have, you can use free conversion software to convert to a format that can be more universally viewed.
