To have your own video blog all you need is a camcorder and a computer with video editing software installed onto it. Popular video editing programs for vloggers are iMovie and Final Cut Pro. These allow you to edit the final video into something you’re proud of; you can crop out mistakes or mishaps and include whatever you want.
Once you have made your vlog with a video editing program, you will also need to find a site to host it so you can share your vlog with the world and access (preferable high speed) to the internet to upload your final vlog.
