Overall, Pinnacle simplifies the editing process. The latest version features new PiP controls, which allow you to add new video into an already existing video. Other editing tools include a pan and zoom tool, a color correction tool, and audio capabilities. It also features several editing tools typically only found in more professional grade editing programs, including a chroma key tool.
You might find that the free video editing software above are either too simple to meet your demends like audio editing and color correction, or too difficult to understand the workflow, then you should look at Wondershare Filmora9, which has significant improvement in overall performance, making the product faster, more powerful, and taking the user editing experience to a new level.
You can also use the build-in video converter tools to freely convert video/audio format to another format. It is a non-linear tool, which means you can place video clips in the timeline freely. You can also export your video to IG, FB and YouTube, which is powerful as a free video editor. You can also edit 4K and HD videos. For this point, not every free video editor can do.
