Field-removed video (FRV) is a technique used in Television Broadcasting to give Television shows recorded on Videotape the same "look and feel" as shows recorded on Film . Once recording television programmes became common in the processes. As it was more expensive, film came to be used only in high-status dramatic projects, while everyday programming such as news, Sitcom s and Soap Opera s were shot on video. FRV was developed in an attempt to give the cheaper video footage a richer, more film-like appearance with all the gravitas that film use implies. Film records at twenty-four Frame s per second while video footage consists of fifty (PAL/SECAM) or sixty (NTSC) picture 'fields' in the same period. FRV involves electronically removing half these fields to give the same 'frame rate' as film. The result gives a similar, dignified, impression of movement similar to film but with the more realistic colour and brightness associated with video. The product is neither film nor video but something in between. If the programme is intended from the start to be in FRV, then it can be Lit and Shot accordingly. A more sophisticated technique called Deinterlacing provides a better image quality, by bringing the two fields that make up a frame into alignment, thus generating a geniune 25/30 frame per second image. Newer television standards, such as ATSC provide for 24, 30 and 60 frame per second video with progressive scanning. The slower two frame rates, shot in progressive scan, would give a film-like appearance, without the reduction in resolution that accompanies field-removed video. Critics of the process accuse it of producing a claustrophobic, artificial image especially in programmes that were initially lit for video and remastered in FRV. The process usually proves unpopular in programmes which adopt it having previously used conventional, undoctored video, and in the United Kingdom , '' Casualty '' and '' Emmerdale '' both returned to conventional video after poor viewer feedback. FRV use is common in the United Kingdom in Situation Comedies such as '' My Family '', to try and match the look and feel of US sitcoms. |
