There are going to be 2 different types of video you will want to upload to your blog: a video you made yourself or a video you found online made by someone else.
To upload a video you made to your blog, the first thing you need to do is turn your iMovie project into a movie file. To do this, while in iMovie go to File > Export. A box will appear in iMovie. The Quicktime tab should be selected, but if it isn’t, click it. Next, choose the compression you want to use for your movie. Because you’re going to be uploading to a website, choose ‘Web’ from the dropdown menu. Then click ‘Share’. Next, type in the box what you want your video to be called and where you want it to be saved. I would recommend the Movies folder. Now click ‘Save’. This will save a .mov version of your film. Remember all videos are saved to the computer you are using, not your school account. This is the same with iMovie projects, so try and remember what computer you’re using so you know where all your files are being saved.
Now you have a movie file, go to www.youtube.com, where your video is going to be hosted. This means, where your video will be kept online. Log into your YouTube account (see the YouTube How To if you’ve forgotten how) and click on Upload. When the page loads, click on the yellow box that says ‘Upload video’. Find your video then click Choose. Once your video has uploaded you can add a description and tags if you want to. If you don’t want to, just click ‘Skip for now’. This will take you to your videos page.
To use a video that you have found online made by someone else, go to the website you found the video on. If you found the video on Blogger, you should see the YouTube logo in the bottom right corner of the video. If you click on this logo it will take you to the page it is hosted on, on YouTube.
This next step is the same whether the video is your own or someone else’s. On the video’s YouTube page, click on the <Embed> button under the video. It’s in the bottom row of buttons on the right, next to the ‘flag’ button. When you click this, a box will appear with a HTML code highlighted in it. Copy the text in the box. If your mouse doesn’t have right click enabled, hold down the ‘ctrl’ button as you click. Or you could use the shortcut, which is ‘cmd’ and ‘C’. Now go to your Blogger dashboard.
On your Dashboard, click on NEW POST. When the New Post box appears, click on the ‘Edit HTML’ tab. Paste the HTML code into this box. Now click back on the ‘Compose’ tab. You won’t be able to see your video on this page, but you will be able to see an outline of where your video will be. Now you can add a title to your post and any text you also want to have in your post. Move the cursor either side of the video, depending on where you want your text, and continue posting as normal.
You now have a video embedded in your blog that can be viewed either on your blog, or on YouTube.
