intraframe การใช้

• This longer command still remains much shorter than intraframe compression.
• However, this process demands a lot more computing power than editing intraframe compressed video with the same picture quality.
• Another difference between intraframe and interframe compression is that, with intraframe systems, each frame uses a similar amount of data.
• Another difference between intraframe and interframe compression is that, with intraframe systems, each frame uses a similar amount of data.
• An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform ( DCT ).
• In order to facilitate instant random access to any frame during editing, all SheerVideo codecs use only intraframe compression, meaning that every frame is a keyframe.
• As a purely intraframe compression scheme, the image-quality of M-JPEG is directly a function of each video frame's static ( spatial ) complexity.
• Unlike some other editing packages, Xpress Pro HD edits HDV natively by decompressing the MPEG-2 stream on the fly, rather than transcoding into an intraframe codec.
• Interframe compression uses one or more earlier or later frames in a sequence to compress the current frame, while intraframe compression uses only the current frame, effectively being image compression.
• Making'cuts'in intraframe-compressed video while video editing is almost as easy as editing uncompressed video : one finds the beginning and ending of each frame, and simply copies bit-for-bit each frame that one wants to keep, and discards the frames one doesn't want.
• It's non-trivial to describe all but the most basic video technologies; modern video uses color-space conversion, chroma subsampling, interframe coding, intraframe coding, and lossy compression, so if you want to record a sound and turn it in to a playable video file, you'll need to know intricate details of each of these concepts.
