In my experience, a two hour Hi8, Video8 or other 8mm tape is around 140 to 200 GB uncompressed, but can be shrunk down to around 50 GB with the most advanced lossless video compression technology available. However, the one flaw of lossless compression is that it might not make the files small enough for a particular workflow. This has the added bonus of being reversible you could reverse the process and end up with the same file you started with. Lossless compression is great because it makes the video files smaller and easier to work with, but does so without damaging picture quality in anyway. This is done through clever mathematical trickery and is what we use here at Archival Works. It is compressing the video file to make it smaller, but doing so without actually losing any quality. ![]() Lossless video compression is exactly that. There’s the term again- “lossless”… But “lossy”? What does that mean? Lossy, is the opposite of lossless that is to say, picture quality HAS been lost. There are two types of compression: lossless compression and lossy compression. To solve this problem we use lossless video compression (sometimes also called “lossless video encoding”) to make video files smaller. These files are so large they can be difficult or even impossible to watch or to work with. A two hour long 4k UHD movie like you might find on Netflix would be 3400 GB-That’s huge! A 60-minute standard definition video (like that from a VHS tape) is a massive 70 GB. Makes sense, but what is it we’re losing? Or in the case of Archival Works, what is it we are NOT losing? The answer? Picture quality.įull quality and uncompressed video files are massive. If something doesn’t have loss, then it is loss-less. Selecting a region changes the language and/or content on short, lossless means exactly what it sounds like. You can reduce the file’s resolution or data rate to help with this. If you’re uploading video content, you want to publish the best video quality possible at a size that’s accessible to the largest possible audience. While some large high-resolution files might play well on high-quality PCs, creators of video content also have to remember many people watch videos on smartphones, older PCs, or with slower Wi-Fi or cellular connections. But if you plan to host the video yourself or want it smaller to share the file more easily, reducing the size of video files is helpful for your audience. ![]() Most social sites like Facebook and YouTube will make your video smaller for playback across a variety of devices when you upload. Then, when you export, Media Encoder will automatically switch back to using your high-resolution sources. Compress video files to a more manageable format like MP4, helping make your workflow more efficient. You might create proxy files, which use a lower data rate but maintain the aspect ratio, for a smoother editing experience. Many video files, like those from a high-end camera, are large and can demand a lot from your machine while you edit, whether you work in Windows or on a Mac. If you are working with high-resolution source files, such as 4K video, reducing the file size of videos also saves time in production.
