Videodigital adalah representasi elektronik dari gambar visual bergerak dalam bentuk data digital yang disandikan. Ini berbeda dengan video analog, yang mewakili gambar visual bergerak dengan sinyal analog. Video digital terdiri dari serangkaian gambar digital yang ditampilkan secara berurutan dengan cepat. FORMAT VIDEO DIGITAL DasarTV digital dan Perbedaan Dari Analog TV TV digital, atau DTV, di sisi lain, ditularkan sebagai data bit informasi, seperti data komputer yang ditulis atau cara musik atau video ditulis pada Disc CD, DVD, atau Blu-ray. Sebuah sinyal digital terdiri dari 1 dan 0 itu. Ini berarti bahwa sinyal yang dikirimkan adalah "on" atau "off". ArsitekturVideo Digital tersusun atas sebuah format untuk mengenkode dan memainkan kembali file video dengan komputer dan menyertakan sebuah player yang dapat mengenali dan membuka file yang dibuat untuk format tersebut. Arsitektur video digital yang utama adalah AppleQuicktime, Microsoft Windows Media Format, dan Real Network RealMedia MPEGhas standardized the following compression formats and ancillary standards:

AVI
Audio Video Interleave, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. AVI files can contain both audio and video data in a file container that Berdasarkanmedia yang digunakan, video dapat dibagi menjadi dua macam, yaitu video analog dan video digital. 2.1.1 Video Analog Video analog adalah video yang menggunakan media analog. Sumber informasi audio berasal dari kaset audio dan mikrofon, dan sumber informasi video berasal dari VHS, 8mm VCR Video Cassette Recorder, dan camcorders. Video analog ini harus dikonversi ke dalam format digital terlebih dahulu untuk dapat diproses oleh komputer. PengertianVideo Analog dan Digital. Video analog adalah Gambar dan Audio direkam dalam bentuk sinyal magnetik pada pita magnetik. Video Digital adalah gambar dan suara digital direkam dalam pita magnetik, tetapi menggunakan sinyal digital berupa kombinasi angka 0 dan 1 (binar) Dalam pembuatan video menggunakan 2 teknik: Interlaced : metode . The following data was compiled from several publications, online and in print, with a range of publications dates. Every attempt has been made to use the most recent information, but some of the formats are historic and some, such as ITU 601 and ITU 709, are still evolving. In the middle of the era where all video is digital, many of you will wonder what the point of knowing analog video. The answer? Digital video appeared yesterday afternoon in regard to the history of audiovisual content, so a large amount of video content is in analog format and is therefore a very important weight in the history of cinema and not forget that human beings experience the world around us in analog format. So in your day to day you capture reality in analog format. But what do we mean by analog? In the digital world when data is transmitted they do so as a succession of binary signals, two values, but when the data is analog then this signal can have any we took the analog signal and digitized it into a digital signal with a very low amount of data then we would not get a sine wave but a square wave. For example the sound called “8 bits” is nothing more than the square wave simplification of the different notes. How then is it possible to digitize a digital signal? Well, adding a greater amount of value changes over time, to bring the signal as closely as possible to the analog when digitizing data, if we want to achieve greater fidelity to reality in a digital system, and therefore a closer approach to reality, then we need a greater amount of data. Hence, the use of video will begin to emerge with 32-bit processors, since they could work with sufficient precision on the do I get the digital video to the PC?The first video digitizer to be used in a computer did not appear for the PC, but for the Commodore Amiga, which arrived in 1990 with New Tek’s Video Toaster. An expansion card that was precisely in charge of taking the NTSC signal and digitizing it for later manipulation, with this the possibility of editing analog video in real time was the collapse of the Commodore Business Machines bankruptcy in 1994 and with the Apple Macintosh being a niche, then all the interest in multimedia turned to the PC where a version of Video Toaster was released, as well as some cards for processing video by part of various brands, all of them based on the use of digital signal processors or DSP, which were added in the first PCs with multimedia capabilities to be able to efficiently treat this volume of data, apart from being able to encode and decode video in real time, the arrival of increasingly powerful processors and digital video ended up eliminating the need to use this type of card for digital video manipulation, which led to the appearance of non-professional programs in the style of iMovie from Apple or Microsofts Windows Movie do I replace analog video to digital?There are three main advantages to digital video over analog video, which have given it dominance in the market over analog video, which has become a relic in history. All three have completely changed the way video is produced, distributed and to process data in real timeThe first of all is that it allows the manipulation of the data by a processor with the ability to manipulate data in digital format, that is, in binary. Which has a series of clear consequences if we take into account that through a processor or CPU we can manipulate them. This allows video editing, in real time and access to any of you who have edited video using analog tape format, you will remember how one hour in analog television resolution required 13 GB of information that had to be dumped from the DV tape to the PC storage disk, so that the CPU could access the timeline. This was impossible to do on tape to catalog and distribute dataThe second is the ability to use metadata, which is data about the data. For example, the metadata for a music file is things like artist name, album, date, genre, and so of the same type can be applied for video files. Which allows us to organize searches through those metadata or keywords. If that data is also in the cloud, then we can set up a digital streaming platform in which to distribute content all over the world. So without digitization we would not have platforms like Netflix, Twitch, Amazon Prime, YouTube, other point is that we can distribute any data in binary, and therefore that has been previously digitized, through the internet. What has allowed the creation of new business quality does not degradeThe third reason has to do with the adoption of digital formats, the first digital format being the Laser-Disc, which was the true predecessor of DVD. The Laser-disc was not very successful for the cost of its players, but its video quality did not degrade as it happened with the video tapes used to store analog video, which over time have had to be digitized. and in some cases it has been too late and they have been lost the digital video boom did not come until the 2000s, a period when real-time video decoding was so cheap in terms of processing that a simple decoder chip cost a few the optical disc formats for movies are about to disappear, replaced by the breakthrough innovation that has been digital video streaming. The demand in addition to series on demand not only new but old has accelerated that many analog videos stored in the archives of many film production companies are digitized. Analog or Digital Video What's the difference? The analog process encodes video and audio in complete frames modulation, with the receiving device interpreting and translating the signal into video and audio on a monitor de-modulation. This process can introduce a progressive loss of data leading to a general loss of video quality. NTSC can only deliver 720 pixels wide video or stills from video. Digital video, or DV, on the other hand, remains digital such as '0's and '1's with the data describing the colors and brightness of each video frame. On the receiving end of this data transmission, there is no translation or interpretation, just the delivery of pure data. The consistency of delivery is the crucial advantage that digital video has over analog video when it comes to working with images on a PC. As opposed to NTSC, there is no limit to resolution so images or movies as wide as 4000 pixels are easily obtainable with the digital cameras we sell for microscopy. When introduced in 1995, Firewire, one of many electronic protocols for A/V also referred to as iLink, IEEE1394 or 1394, provided both the transfer speed, at 400Mpbs, and the consistency needed to allow the average user to edit video on their PC. What About USB In the past, there was a clear distinction between USB and Firewire. USB could not transfer high quality DV; loosely defined as 25 frames per second fps with each frame being 640x480 resolution, due to transfer limit of around 11Mbps or around per second. Transferring DV requires a transfer rate of at least per second, which at the time left Firewire as one of few options due to its ability to work at 400Mbps, or up to around 50MB per second. Then along came USB with a "published" transfer rate of 480Mbps or 60MB per second. Not to be left behind by Wintel, at least on paper, Firewire800 or IEEE1394b was introduced. The new standard also provided for even faster and transfer rates across 100 meters of copper twisted pair wires. At first glance, it appears that USB is faster than Firewire400; however speed is not the only issue when it comes to DV. One of the worst issues with USB is that it cannot guarantee a sustained data transfer rate. This is due to USB adopting a "master-slave" topology, which means it needs the computer's CPU to coordinate data transfers. While this not usually a problem for low demand peripherals such as webcams, scanners, printers, etc., digital video requires dependable high-performance to avoid dropping video frames. Firewire was designed from the beginning as a real time protocol. Firewire also works in a peer-to-peer topology. As a result, many professional DV users can download their video clips from a DV camcorder directly to a hard drive without the use of a PC. More importantly, Firewire delivers data consistently at a specified high rate. If you want to do serious work with video, even to edit a family movie, it is best to go with Firewire. What does Meiji recommend for microscopy? Analog CCD cameras are still the best way to go if you want to use a video projector or a big screen TV or monitor like in classroom or training situations. To work with high-resolution digital video or digital still images for print publication, then our CMOS or CCD Digital Video Cameras are the best choice. Digital video cameras that use are fine for work done with microscopes because videos captured on microscopes are relatively short clips in duration. Also when using a video system, we suggest using a newer, fast computer with no other applications or TSR's running in the background or better yet, using a dedicated computer to do microscope video imaging. is found on all new PC or Macintosh type computers, whereas Firewire is typically an add-on card for most PC's. All Meiji Techno Digital Video Cameras use with no current plans for Firewire cameras. Firewire is native to most Macintosh computers so finding a Firewire camera is probably the best way to go if you are a Mac user. Pengertian video digital adalah video yang proses perekamannya menggunakan sensor / komputer/ kamera digital, hasil proses perekamannya dalam bentuk file atau data, sedangkan video analog proses perekaman nya menggunakan film atau lebih kita kenal dengan kaset video. Hasil akhirnya analog berbentuk kaset video. Perlu diketahui juga perbedaan format Digital dan Analog 1. Format Analog Salah satunya adalah VHS, S- VHS, Beta, Hi- 8 , mini DV dan masih menggunakan kaset sebagai tempat produk akhirnya. Kekurangan format analog adalah tidak bisa disimpan dalam jangka waktu lama. Karena masih berupa pita kaset yang terbuat dari bahan plastik dan magnetik. Karena dalam jangka waktu lama dan tejadi berubahan suhu ruangan tentunya akan rusak dan berjamur. 2. Format Digital Teknologi Digital/komputer mempunyai banyak kelebihan. Beberapa file AVI, MOV, MPEG1 VCD, MPEG2 DVD, DV, MPEG4 MP4 . File dan datanya diperoleh dengan menggunakan kamera digital dan filenya bisa disimpan sesuai kebutuhan.
