This tutorial wraps up the basic knowledge that you need to edit your first home video end-to-end. Exporting is the process where you create a new video file incorporating all the edits. In this tutorial, I explain the concepts of file formats, codecs, and bit rates.
One extra tidbit over and above what’s in the tutorial – there are times when you will want to set a lower bitrate, rather than a higher one. This is because higher bitrates create bigger files, so if you absolutely need a compact file, you will want to lower the resolution and bitrate. For example, if you want to upload a PowerPoint presentation to your work intranet website, you can use low resolution and bitrate to make the file small enough to embed and play on the site.
