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. 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.
