DIGIMED S15 - Video

  1. 1. Adobe Premiere Pro 2.0 Adoremus, Daniel Joseph Chua, Chester Espinosa, Gian Sancio, Robert
  2. 2. History <ul><li>How Adobe Premiere was made? </li></ul><ul><ul><li>Adobe Premiere was first made during December 1991, it was first made to support quicktime multimedia format and was initially made for Mac. Over the years it was developed and tracks and fps were included in the program and sometime during September 1993 it was made and released for Windows. Up until now the program is still constantly undergoing upgrades and soon there would be better versions of it. </li></ul></ul>
  3. 3. History <ul><li>What is Adobe Premiere? </li></ul><ul><ul><li>Adobe Premiere is a powerful video editing software tool, capable of producing broadcast-quality and high definition video. It is very popular and suitable for video enthusiasts and professionals and even amateurs can use it because it has a very easy to use interface. Adobe Premiere can also be used alongside other applications such as Adobe Photoshop and After Effects. </li></ul></ul>
  4. 4. History <ul><li>Use of Adobe Premiere? </li></ul><ul><ul><li>Import video, audio and graphics in a wide variety of formats. </li></ul></ul><ul><ul><li>Edit, manipulate and arrange these elements in a visual timeline. </li></ul></ul><ul><ul><li>Add effects, filters, titles, etc. </li></ul></ul><ul><ul><li>Export your edited video in a variety of formats, including video tape recordings, DV, DVD, and common Internet video formats. </li></ul></ul>
  5. 5. What is Video? <ul><li>Definition </li></ul><ul><ul><li>Video is the technology of electronically capturing, recording, processing, storing, transmitting and reconstructing a sequence of still images representing scenes in motion. Video technology was first developed for television systems, but has been further developed in many formats that allow video recording. Video can aslo be viewed through the internet as video clips or streaming media clips on computer monitors. </li></ul></ul>
  6. 6. Video formats and comparison and contrast <ul><li>Video formats are commonly known in the domain of commercial broadcast and consumer devices; most notably to date, these are the analog video formats of NTSC, PAL and SECAM. </li></ul><ul><li>Lines/Fields – also known as refresh rate, is the number of times in a second that a display is illuminated, Increased refresh rate decreases flickering thus reducing eye strain but too much can lead to the monitor to be damaged. </li></ul><ul><li>Horizontal Frequency – usually measured in kilohertz, is the frequency in which the movement of the electrobeam from the right side to the back and displays the number of horizontal lines displayed. </li></ul>
  7. 7. <ul><li>Vertical Frequency – similar to horizontal frequency but it is the vertical lines being displayed. </li></ul><ul><li>Color Subcarrier Frequency – the color is determined by how the chroma frequency part of the picture is delayed from the reference frequency. Determines how the color of the image would be based on the difference of the frequencies. </li></ul><ul><li>Video Bandwidth – frequency range that the system or complete component can pass where the frequencies are reproduced, transmitted or amplified. </li></ul>Video formats and comparison and contrast
  8. 8. <ul><li>Sound carrier – frequency where the sound is recorded. </li></ul><ul><li>NTSC – National Television System Committee, </li></ul><ul><li>PAL – Phase Alternating Line, </li></ul><ul><li>SECAM – Sequential color with memory, </li></ul>Video formats and comparison and contrast
  9. 9. Video formats and comparison and contrast
  10. 10. Uses the latest technology to bring clearer and sharper television pictures to your home. HD services are already on-air in some parts of the world. It also gives you a lifelike viewing experience, with sharper images, more vibrant colours and deeper detail. Its better than cinemas and it gives you pure intense detail where you can appreciate what you are watching. NTSC video has a resolution of about 330. A VHS tape has about 240 lines of resolution. DVDs have about 480 lines of resolution, which is the highest resolution a standard TV can display. High Definition televisions on the other hand, can display 1080 lines of vertical resolution, twice that of an ordinary TV and three times as much as broadcast television.
  11. 12. <ul><li>HD formats are broken down into five categories: </li></ul><ul><li>480p: A progressive scan version of the standard TV image. </li></ul><ul><li>720p: Widescreen progressive scan with 720 lines of resolution. 1280X720 at 30 or 60 fps. </li></ul><ul><li>1080p: The Holy Grail of High Definition: 1920x1080 resolution at 30 or 24 (film) fps, </li></ul>
  12. 13. <ul><li>HDV is an inexpensive high-definition video recording format which uses MPEG2 compression to fit HD content onto the same DV or MiniDV tapes originally developed for standard definition recording </li></ul><ul><li>HDV stores 16:9 high definition video on DV tapes, supporting both 720p and 1080i (NTSC and PAL), using MPEG-2 compression for data rates of 19Mbps and 25Mbps respectively, comparable to the bitrates of ordinary DV (25Mbps). Audio is compressed by 75% using MPEG-1 Layer 3. </li></ul>
  13. 14. <ul><li>What is DV? </li></ul><ul><ul><li>Stands for &quot;Digital Video.&quot; Unlike traditional analog video, which is captured frame by frame on a tape, digital video is recorded digitally, as ones and zeros. Since it is stored in a digital format, digital video can be recognized and edited by a computer, which is also a digital device. </li></ul></ul><ul><ul><li>DV camcorders, including Mini DV and HDV, record digital video and therefore can export the footage to a computer using a Firewire (IEEE 1394) cable. Analog camcorders such as SVHS and Hi-8 devices must be run through a analog to digital converter (DAC) in order to be transferred to a computer. </li></ul></ul>
  14. 15. <ul><li>The 24p frame rate is now widely adopted by those planning on transferring a video signal to film. But film and video makers turn to 24p for the &quot;cine&quot;-look even if their productions are not going to be transferred to film, simply because of the &quot;look&quot; of the frame rate. </li></ul><ul><li>Capturing video at 24p offers film-like motion, which is more suitable for narrative projects and creates more film-like images. Some vendors market 24p products as a cheaper alternative to film acquisition. </li></ul>
  15. 16. <ul><li>When working entirely within the digital non-linear domain, 24p material is as easily handled as material at any other frame rate. However, 24p material requires care when it is processed using equipment designed for standard video frame rates. </li></ul><ul><li>There are two common workflows for processing 24p material using video equipment, one using PAL frame rates, and the other using NTSC frame rates. Of these two, the PAL route is the simpler, but each has its own complications. </li></ul><ul><li>24p video has more trouble with high motion than other, higher frame rates, sometimes showing a &quot;strobe&quot; or &quot;choppy&quot; motion </li></ul>
  16. 17. <ul><li>NTSC is the analog television system in use in Canada, Japan, Mexico, the Philippines, South Korea, Taiwan, the United States, and some other countries, mostly in the Americas. It is named for the National Television System Committee </li></ul><ul><li>The NTSC standard for television defines a composite video signal with a refresh rate of 60 half-frames (interlaced) per second. Each frame contains 525 lines and can contain 16 million different colors.   </li></ul><ul><li>The NTSC standard is incompatible with most computer video standards, which generally use RGB video signals. However, you can insert special video adapters into your computer that convert NTSC signals into computer video signals and vice versa. </li></ul>
  17. 18. <ul><li>NTSC is the video system or standard used in North America and most of South America. In NTSC, 30 frames are transmitted each second. Each frame is made up of 525 individual scan lines. </li></ul><ul><li>PAL is the predominant video system or standard mostly used overseas. In PAL, 25 frames are transmitted each second. Each frame is made up of 625 individual scan lines. </li></ul>
  18. 19. <ul><li>PAL format has greater resolution than NTSC, it is generally accepted as being of higher quality. NTSC receivers have a tint control to perform colour correction manually. If this isn't adjusted correctly, the colours will be faulty. The PAL standard automatically removes hue errors by utilizing phase alternation of the colour signal, so a tint control is unnecessary. </li></ul>
  19. 20. FPS <ul><li>a measure of how much information is used to store and display motion video. The term applies equally to film video and digital video. Each frame is a still image; displaying frames in quick succession creates the illusion of motion. The more frames per second (fps), the smoother the motion appears. Television in the U.S., for example, is based on the NTSC format, which displays 30 interlaced frames per second (60 fields per second). In general, the minimum fps needed to avoid jerky motion is about 30. Some computer video formats, such as AVI, provide only 15 frames per second. </li></ul>
  20. 21. <ul><li>Frame rates in video games </li></ul><ul><li>Frame rates are considered important in video games. The frame rate can make the difference between a game that is playable and one that is not. The first 3D first-person adventure game for a personal computer, 3D Monster Maze, had a frame rate of approximately 6 fps, and was still a success, being playable and addictive. Most modern action games, including popular first person shooters such as Halo 3, run around 30 frames a second, while others, such as Call of Duty 4, run at 60 frames a second. </li></ul>
  21. 22. What are effects? <ul><li>Definition </li></ul><ul><ul><li>Visual effects created in the computer that provides interesting transitions from one scene to another rather than just switching frames. They include fading or dissolving the frame, wiping one frame over another and flipping the frame. (thefreedictionary.com, 2007) </li></ul></ul><ul><ul><li>Synthetic sounds and animations created in the digital domain. Reverberation, morphing and transitions between video frames are examples.(pcmag.com, 2007) </li></ul></ul>
  22. 23. What are effects? <ul><li>Adjust </li></ul><ul><ul><li>Auto Color, Contrast, Level </li></ul></ul><ul><ul><ul><li>The Auto Color, Auto Contrast, and Auto Levels make quick global adjustments to a clip. </li></ul></ul></ul><ul><ul><li>Brightness and Contrast effect </li></ul></ul><ul><ul><ul><li>The Brightness & Contrast effect adjusts the brightness and contrast of the entire clip. The value 0.0 indicates that no change is made. </li></ul></ul></ul><ul><ul><li>Color Balance effect </li></ul></ul><ul><ul><ul><li>The Color Balance effect changes the amount of red, green, and blue color in a clip. </li></ul></ul></ul><ul><ul><li>Extract effects </li></ul></ul><ul><ul><ul><li>The Extract effect removes colors from a video clip, creating a textured grayscale appearance </li></ul></ul></ul>
  23. 24. What are effects? <ul><li>Blur & Sharpen </li></ul><ul><ul><li>Camera Blur </li></ul></ul><ul><ul><ul><li>The Camera Blur effect simulates an image leaving the focal range of the camera, blurring the clip. </li></ul></ul></ul><ul><ul><li>Gaussian Blur </li></ul></ul><ul><ul><ul><li>The Gaussian Blur effect blurs and softens the image and eliminates noise </li></ul></ul></ul><ul><ul><li>Gaussian Sharpen </li></ul></ul><ul><ul><ul><li>The Gaussian Sharpen effect sharpens a clip by a large amount; the effect is similar to that of choosing the Sharpen effect several times. </li></ul></ul></ul><ul><ul><li>Ghosting </li></ul></ul><ul><ul><ul><li>The Ghosting effect overlays transparencies of the immediately preceding frames on the current frame. </li></ul></ul></ul><ul><ul><li>Sharpen </li></ul></ul><ul><ul><ul><li>The Sharpen effect increases the contrast where color changes occur. </li></ul></ul></ul>
  24. 25. What are effects? <ul><li>Keying </li></ul><ul><ul><li>Chroma Key </li></ul></ul><ul><ul><ul><li>The Chroma Key effect keys out all image pixels that are similar to a specified key color. </li></ul></ul></ul><ul><ul><li>Green Screen </li></ul></ul><ul><ul><ul><li>The Green Screen Key effect keys out all image pixels that are similar to a standard greenscreen, so that they become transparent. </li></ul></ul></ul><ul><ul><li>Blue Screen </li></ul></ul><ul><ul><ul><li>The Blue Screen Key effect makes all image pixels that are similar to a standard bluescreen transparent. </li></ul></ul></ul>
  25. 26. What is Sequence in Adobe Premiere? <ul><li>Definition </li></ul><ul><ul><li>You assemble and rearrange sequences in the Timeline panel, which represents a sequence graphically, showing clips, transitions, and effects. </li></ul></ul>
