A good video, whether it be a music video, movie trailer, game walkthrough, camera recording or anything, must be edited after production. But how to edit video on Mac? Filtering, adding subtitles, adding watermark, trimming, rotating, cropping and fading are all included in video editing, but here we're talking about video cutting on Mac. The most basic of video edits is to lop the ends off a clip, to split a long video into clips and to trim a video to make it smaller. After all, watching an exaggerated long video is the equivalent of a conversation with someone who can't get to the point. It's painful. So for everyone's sake, trim and cut videos on your Mac.
Why You Need Trim/Cut/Split Video Clips?
Firstly, this is closely related to your ultimate goals. In other words, it depends on what will you do with the video. Generally, the reasons why people cut their videos come that they want to:
• Upload videos to the web. Video sharing sites has its requirement of the video length, for example, Facebook allows video no longer than 120 minutes, Basic YouTube account accepts videos shorter than 15 minutes, and Instagram supports video of 60 seconds at most. So it's advisable to cut and edit video for Insta, YouTube, Facebook, and the like.
• Reduce size for storage. If you have a limited capacity, like 64GB iPhone, 5GB free storage iCloud space, or a slightly small hard drive, you can cut videos to remove the non-significant parts to reduce the video file size for storage.
• Remove the cruft for a perfect flow. It's inevitable that your recordings are interrupted by unexpected conditions, such as the flickering light, the passersby, or the elusive weather. To ensure a perfect flow, you need cut all these least anticipates out.
• Send videos by email or social media. No matter you'd like share videos with your friends by sending emails or through social media, you have to compress video firstly since they have no access for large videos. For example, Whatsapp allows for videos smaller than 16MB. And video trimming is undoubtedly the most direct way to get it smaller.
• Burn video to DVD discs. There are mainly four sizes for DVDs, DVD-5 (4.37GB), DVD-9(7.95GB), DVD-10(8.75GB), DVD-18(15.9GB). If you'd like burn your large-sized 4K UHD videos to DVD, you do need a 4K video editor to cut 4K videos within the DVD size limits.
Besides, it has something to do with video sources. I mean people get videos in various ways, like record video with DSLR cameras, GoPro, mobiles, download videos from online, or rip videos from DVD, leading a variety of video codecs and formats. Thus to achieve all the goals above, you're asked not only to cut video on Mac, but also a step of re-encoding videos for wide compatibility.
