Offline and Real Time editing is a post-production process of film making. Both are used in the film industry, as an approach to copy, edit, and share videos. Offline Video Editing is part of the post-production process of film making and television production in which raw footage is copied and edited, without affecting the camera original film stock or video tape. Modern offline video editing is conducted in a non-linear editing (NLE) suite. Editing with reduced-quality copies of your media files allows you to fit more media on your scratch disks and improve playback and real-time effects performance (especially when using slower hard disks, such as in portable computers). This phase can last from a few days to several years, depending on the scope of the project, the amount of footage, and so on. The digital revolution has made the offline editing workflow process immeasurably quicker, as practitioners moved from time-consuming (video tape to tape) linear video editing online editing suites, to computer hardware and video editing software such as Adobe Premiere, Final Cut Pro, Avid, Sony Vegas, Lightworks and VideoPad. Typically, all the original footage (often tens or hundreds of hours) is digitized into the suite at a low resolution. The editor and director are then free to work with all the options to create the final cut.
Real-time video editing is a system of editing video where it takes no longer to render a video than the length of that video clip itself. Broadcasters traditionally used large, disparate computer systems for real-time video editing with multiple CPUs, multiple gigabytes of RAM and high-powered hard drives. Some had additional hardware components designed to enhance the performance of the specific video editing software being used. Other approaches used to ensure real-time playback included continuous background rendering, and using multiple networked computers to share the rendering load. These systems would allow broadcasters to edit and render a video clip in 30 minutes. Online editing, now better known as finishing, starts with an offline project file or a project interchange file, which describes the media you need to re ingest at full quality. Online editing actually has very little to do with editing in the traditional sense. Timing, storytelling, and fine-tuning your edits should be complete in the offline editing phase. Online editing focuses on image quality, color correction, maintaining broadcast video specifications, detailed effects work, titles, audio levels, and so on. Compared to the offline editing phase, an online edit session goes very quickly (anywhere from a day to a week), and generally requires more expensive equipment.
These systems are now outdated thanks to the instantaneous nature of social media platforms such as Facebook and Twitter. Broadcasters and content rights holders now use cloud-based video editing technology which allows them to clip, edit and share video across multiple digital platforms such as websites and social apps within seconds rather than minutes. Nowadays people are using google to save and store files online using cloud storage.
