Recording video and audio to a digital format involves balancing quality with file size and bitrate. Most formats use compression to reduce file size and bitrate by selectively reducing quality. Compression is essential for reducing the size of movies so that they can be stored, transmitted, and played back effectively. When exporting a movie file for playback on a specific type of device at a certain bandwidth, you choose an encoder ( codec). Various encoders use various compression schemes to compress the information. Each encoder has a corresponding decoder that decompresses and interprets the data for playback. A wide range of codecs is available; no single codec is best for all situations. For example, the best codec for compressing cartoon animation is generally not efficient for compressing live-action video. Compression can be lossless (in which no data is discarded from the image) or lossy (in which data is selectively discarded). You can control many of the factors that influence compression and other aspects of encoding in the Export Settings dialog box. Adobe Media Encoder runs on both Macs and Windows and is the compression. Video tutorials. 7 Responses to Product Review: Sorenson Media Squeeze 9 Pro. Sorenson Media's Squeeze Desktop Pro is for.

John Dickinson provides a video tutorial on the Adobe website that demonstrates the use of Adobe Media Encoder.

For more information about encoding and compression options, see this FAQ entry. The two general categories of compression for video and audio data are spatial and temporal. Spatial compression is applied to a single frame of data, independent of any surrounding frames. Spatial compression is often called intraframe compression. Cara download wechat di hp bb.

Temporal compression identifies the differences between frames and stores only those differences, so that frames are described based on their difference from the preceding frame. Unchanged areas are repeated from the previous frames. Temporal compression is often called interframe compression. Video is a sequence of images that appear on the screen in rapid succession, giving the illusion of motion. The number of frames that appear every second is known as the frame rate, and it is measured in frames per second (fps). The higher the frame rate, the more frames per second are used to display the sequence of images, resulting in smoother motion. The trade-off for higher quality, however, is that higher frame rates require a larger amount of data, which uses more bandwidth. When working with digitally compressed video, the higher the frame rate, the larger the file size. To reduce the file size, lower either the frame rate or the bitrate. If you lower the bitrate and leave the frame rate unchanged, the image quality is reduced. Because video looks much better at native frame rates (the frame rate at which the video was originally recorded), Adobe recommends leaving the frame rate high if your delivery channels and playback platforms allow it. For full-motion NTSC video, use 29.97 fps; for PAL video, use 25 fps. If you lower the frame rate, Adobe Media Encoder drops frames at a linear rate. However, if you must reduce the frame rate, the best results come from dividing evenly. For example, if your source has a frame rate of 24 fps, then reduce the frame rate to 12 fps, 8 fps, 6 fps, 4 fps, 3 fps, or 2 fps. For mobile devices, use the device-specific encoding presets. You can also use Adobe Device Central to determine the appropriate settings for many specific mobile devices. For information about Device Central, see Device Central Help. Note: Key frames are not the same as keyframes, the markers that define animation properties at specific times. By default, Adobe Media Encoder automatically determines the key frame interval (key frame distance) to use based on the frame rate of the video clip. The key frame distance value tells the encoder how often to re-evaluate the video image and record a full frame, or key frame, into a file. Tha carter iii zip.
