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.

Conversores Format Factory BAB II DASAR TEORI Dalam bab ini diuraikan dasar-dasar teori yang mendukung pelaksanan Tugas Akhir ini, yaitu tentang Video, AVI, BMP, dan Steganografi. Video 1. 2. Video merupakan urutan citra diam yang digabungkan, menjadikannya sebuah gambar bergerak. Sedangkan citra merupakan tiruan, representasi, atau kesamaan atas seseorang, sesuatu, atau tindakan yang dilukis, digambarkan, dibentuk, atau dengan cara lainnya sehingga dapat ditangkap oleh pandangan manusia [SUP00]. Berdasarkan media yang digunakan, video dapat dibagi menjadi dua macam, yaitu video analog dan video digital. 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. Format Video Analog Video analog dapat disimpan dalam beberapa format, di antaranya NTSC National Television Standards Committe Merupakan format video televisi yang digunakan di Amerika Serikat dan sekitarnya. Menampilkan 525 baris resolusi pada 60 field per detik dan 30 frame per detik. PAL Phase Alternation Line Merupakan format video televisi yang digunakan di Eropa dan sekitarnya. Menampilkan 625 baris resolusi pada 50 field per detik dan 25 frame per detik. II-1 Video Digital Video digital adalah video yang menggunakan media digital. Sumber informasi audio dan video berasal dari CD audio, DV, miniDV, Digital8 camcorders, dan DVD yang menyimpan audio dan video di dalam format digital. Data video digital dapat diproses secara langsung oleh komputer, dan digandakan tanpa mengurangi kualitas. 1. Sinyal Video Digital Sebuah sinyal video digital merupakan kombinasi dari tingkat keterangan luminance atau luma dan warna chrominance atau chroma. Tingkat keterangan luminance adalah intensitas terang-gelapnya cahaya pada sinyal video, biasanya direpresentasikan dengan huruf Y. Sinyal video dipisahkan menjadi komponen luma dan chroma warna untuk kualitas yang lebih besar serta transmisi dan pengkodean yang efisien. Sinyal video disajikan dalam format YUV, di mana informasi warna direpresentasikan dalam U dan V. Sebuah sinyal video digital dibagi menjadi tiga sinyal terpisah untuk mencegah penurunan kualitas dari perpaduan sinyal-sinyal. Komponen sinyal ini terdiri atas RGB red, green, dan blue, luma Y, dan dua sinyal chroma, sebagai contoh Y, Y-R, Y-B, atau dalam format lain dituliskan sebagai YUV, YCbCr, dan Y Pr Pb. Format Video Digital Video digital dapat disimpan dalam beberapa format yang berbeda. Tiap format dari video digital memiliki karakteristik masing-masing, kelebihan dan kekurangan, serta tujuan penggunaan yang berbeda-beda. Berikut beberapa format video digital yang umum digunakan AVI Audio Video Interleave Merupakan format video digital yang paling banyak digunakan pada Personal Computer dan di internet. Data disimpan di dalam blok-blok untuk mengurangi ukuran file, beberapa kompresor dapat mengkompresi file dengan format ini hingga mencapai perbandingan 1001. File dengan format ini tidak praktis jika dikirimkan melalui internet karena ukurannya yang sangat besar. 2. 3. 4. 5. 6. 7. DV Digital Video dan Mini-DV Merupakan format video digital kompresi untuk keperluan video profesional. Format kompresi DV digunakan untuk DV dan Digital-8 camcorder. Video dan audio berformat DV dapat di-capture menggunakan antarmuka FireWire IEEE 1394, kemudian disimpan dan diedit dengan editor video. MPEG Moving Picture Expert Groups Merupakan format file multimedia yang populer yang ditetapkan oleh sebuah grup bernama Moving Pictures Expert Group. MPEG telah memproduksi berbagai macam standard yang masing-masing memiliki aplikasi berbeda. Quick Time .mov File dengan format ini hanya dapat dijalankan dengan perangkat QuickTime Player, yang merupakan perangkat multimedia yang menawarkan kreativitas dan fleksibilitas, serta memberikan kulitas terbaik. Dapat menampilakn 99 track audio, video, 3D, teks, HTML, dan VR, serta dapat disisipkan dengan mudah di halaman web. Real Media .rm dan Real Video .rv File dengan format ini mudah di-streaming atau di-download melalui internet, memiliki kecepatan kompresi yang tinggi tetapi dapat menurunkan kualitas. Flash dan Shockwave .swf File dengan format ini dibuat dengan menggunakan Macromedia Flash atau Macromedia Director, dan ditampilkan dengan perangkat Macromedia Flash Player atau Shockwave Player. Dapat diintegrasikan ke dalam halaman web atau diputar sebagai film seperti pada format lainnya. WMV Windows Media Video Merupakan kompresi file videoaudio dengan Microsoft Windows Media codec. AVI Audio Video Interleave, atau disingkat AVI, adalah format file multimedia yang diperkenalkan oleh Microsoft pada bulan November 1992. File AVI dapat mengandung data audio dan video dalam suatu media, yang memungkinkan audio dan video dimainkan bersamaan. Seperti DVD, file AVI mendukung streaming, baik audio dan video, walaupun jarang dilakukan. Hampir semua file AVI menggunakan format ekstensi file .AVI. File-file ini didukung oleh Microsoft, dan disebut “AVI AVI merupakan kasus khusus dari Resource Interchange File Format RIFF, yang membagi file data ke dalam blok-blok. Setiap blok diidentifikasi dengan tag FourCC. Sebuah file AVI mengambil format blok tunggal di dalam file RIFF, yang kemudian dibagi menjadi dua blok perintah dan satu blok opsional. Struktur dari sebuah file RIFF rupanya menyalin dari format IFF sebelumnya yang ditemukan oleh Electronic Arts pada pertengahan 1980-an. Bagian pertama blok pada AVI diidentifikasi dengan tag “hdrl”. Blok ini merupakan file header dan mengandung metadata tentang video, seperti lebar, tinggi, dan laju frame. Bagian kedua blok diidentifikasi dengan tag “movi. Blok ini mengandung data audiovisual yang membangun film AVI. Blok opsional ketiga diidentifiki dengan tag idx1 yang menunjukkan indeks alamat-alamat fisik blok data. BMP 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. Last updated on May 9th, 2023 at 0244 pm Digital video and analog video are two distinct forms of video recording and playback technology. While both are video formats utilized to record and display video content, they differ in several key ways. Firstly, analog video is an older technology that uses a continuous, analog signal to capture and display images. On the other hand, digital video uses a binary code to represent data and translates the code into images or sounds for display. Below are some other differences between digital video and analog video. Resolution Analog video has a lower resolution than digital video. Noise Analog video is more susceptible to interference or noise that could cause the image to appear blurry, grainy, or otherwise distorted compared to digital video. Editing Digital video offers greater flexibility in editing and post-production work. This is because digital video can be edited, copied, and shared without compromising quality, whereas, with analog video, there is a limit to how much editing can be done without compromising the quality of the footage. Distribution With digital video, distribution is easier and more convenient as it can be easily transferred over the internet, email, or other digital means. Analog video tapes, however, require physical transportation, which can be both time consuming and inconvenient. Overall, the key difference between digital and analog video lies in the way they represent and manipulate data. While analog video is the older technology, it still has its uses, especially in niche markets. But with the rise of digital technology, digital video has come to dominate the marketplace due to its versatility, higher resolution, better editing capability, and easy distribution. Pro Tips 1. Digital video is compressed and saved in a digital format, while analog video is recorded and played back with magnetic tapes or discs. 2. When it comes to quality, digital videos are often cleaner and less prone to noise and distortion compared to analog videos. 3. Editing and manipulating digital videos are easier and more convenient than analog videos, which often require physical splicing and cutting. 4. With digital videos, it’s possible to store and stream videos online without the need for physical copies or tapes. In contrast, analog videos require physical storage and can degrade over time. 5. Digital videos offer a wider range of video resolutions and refresh rates compared to analog videos, allowing for more refined visuals and smoother playback. The basics of digital videoUnderstanding analog video technologyCharacteristics of digital videoComparing analog and digital video qualityDigital video storage and compressionAdvantages and disadvantages of analog videoAdvantages and disadvantages of digital video The basics of digital video Digital video is a type of video that is recorded and played back in a digital format. When analog video is recorded, it is recorded in a continuous signal, whereas digital video is recorded and played back in discrete pieces of data, or “samples”, that are compressed into a digital file. This compression technique is what makes digital video possible, as it allows the file size to be reduced without losing quality. Understanding analog video technology Analog video, on the other hand, is recorded in a continuous signal that is constantly fluctuating between different values. This analog signal is then transformed into a composite video signal, which is used to display the video on a television screen. The quality of analog video is dependent on the quality of the recording equipment and the quality of the display device. Characteristics of digital video Digital video has several characteristics that make it unique compared to analog video. For one, digital video can be easily edited and manipulated using video editing software. Digital video is also more reliable than analog video, as it is not subject to signal degradation or interference. In addition, digital video allows for high-quality playback on a wide variety of devices, including smartphones, tablets, laptops, and desktop computers. Comparing analog and digital video quality When it comes to video quality, digital video has several advantages over analog video. For one, digital video is capable of producing high-definition video with crystal-clear picture quality. Digital video is also capable of producing high-quality sound, as digital sound can be easily added to a digital video file. In contrast, analog video is limited in its quality, as it is subject to signal degradation, interference, and loss of quality over time. Digital video storage and compression Digital video files are typically compressed in order to reduce the file size and make them easier to store and transmit. Compression algorithms, such as MPEG and are used to reduce the file size of digital video files without compromising their quality. However, compression can also lead to a loss of quality, particularly if the compression is too severe. In addition, digital video files require a significant amount of storage space, particularly if they are recorded in high definition. Advantages and disadvantages of analog video Analog video has several advantages over digital video. For one, analog video does not require as much storage space as digital video files. In addition, analog video is typically less expensive than digital video equipment. On the downside, however, analog video is subject to signal degradation and interference, and it is not as reliable as digital video. Analog video is also limited in terms of quality, as it is not capable of producing high-definition video. Advantages and disadvantages of digital video Digital video has several advantages over analog video.

On the downside, however, digital video files require a significant amount of storage space, and compression can lead to a loss of quality. Digital video equipment is also typically more expensive than analog video equipment. In conclusion, the main difference between digital and analog video is the way they are recorded and played back. Digital video is recorded and played back in a digital format using discrete pieces of data, while analog video is recorded in a continuous signal that is transformed into a composite video signal. While analog video has some advantages, such as lower cost and less storage space required, digital video is generally considered to be more reliable and versatile, with better quality and editing capabilities. Ultimately, the choice between analog and digital video will depend on the specific needs and preferences of individual users.
