You can record the video or download the entire video and then edit or cut it into parts as you desire with the help of a good video editing software in PC but that needs time and some skills. It might also need some bucks to buy that software. It sounds good if you regularly edit video but if it is not what you do in your daily life then you need a free online tool that does the job easily. Downloading videos from YouTube and other video streaming websites is easy. Many software and online tools allow just that. What if you want to download a portion of video from YouTube and not the whole video? What about downloading video in your preferred format? Record, slice, convert and download nearly any audio or video URL to common formats by using these online tools.
