![]() ![]() The original 2" Quadruplex system cost so much that many television production facilities could only afford a single unit, and editing was a highly involved process that required special training. Like some other technologies, the cost of video editing has declined over time. VirtualDub is a popular open source video editing software Home video editing Later, in the 1980-90's came the smaller beta equipment (named for the B-shaped tape path), and more complex controllers, some of which did the synchronizing electronically. That system used two tape players and one tape recorder, and edits were done by automatically having the machines back up, then speed up together simultaneously, so that the edit didn't roll or glitch. A popular 1970-80s system for creating these transitions was the U-matic equipment (named for the U-shaped tape path). In addition, sources could be played back simultaneously through a vision mixer (video switcher) to create more complex transitions between scenes. If a scene closer to the beginning of the video tape needed to be changed in length, all later scenes would need to be recorded onto the video tape again in sequence. ![]() This was introduced into the linear editing technique. Improvements in quality and economy, and the invention of the flying erase-head, allowed new video and audio material to be recorded over the material already present on an existing magnetic tape. With the two black jog dials, two connected VCRs could be precisely controlled to add image frames from a source machine to the video material on a second, recording machine. ![]() Video editing controller Sony BVE-600 for the analog U-Matic system, 1980s. This "developed" the magnetic tracks, making them visible when viewed through a microscope so that they could be aligned in a splicer designed for this task. The two pieces of tape to be joined were painted with a solution of extremely fine iron filings suspended in carbon tetrachloride, a toxic and carcinogenic compound. Įarly 1950s video tape recorders (VTR) were so expensive, and the quality degradation caused by copying was so great, that a 2-inch Quadruplex videotape was edited by visualizing the recorded track with ferrofluid, cutting it with a razor blade or guillotine cutter, and splicing with video tape. The goal of editing is to manipulate these events to bring the communication closer to the original goal or target. Using video, a director can communicate non-fictional and fictional events. Motion picture film editing is a predecessor to video editing and, in several ways, video editing simulates motion picture film editing, in theory and the use of linear video editing and video editing software on non-linear editing systems (NLE). Video editing is the process of editing segments of motion video production footage, special effects and sound recordings in the post-production process. A vision mixer is used to cut live feed coming from several cameras in real time.
