These factors help to\u003cbr\u003edetermine the type of video that you are doing as well as the final product. If these\u003cbr\u003efactors are off any then you will end up with a lousy video. So make sure that you\u003cbr\u003eunderstand the factors that are involved when creating videos and how these factors\u003cbr\u003eeffect how your video plays.\u003cbr\u003eBit depth is one of the factors that come into play when you are creating video files for\u003cbr\u003ethe web. To explain bit depth very simply, it is what determines the color resolution in\u003cbr\u003eyour video. High bit depths are used when creating large video files. Lower bit depths\u003cbr\u003eare used for smaller video files or for when you want control over the color resolutions.\u003cbr\u003eFrame size is also a factor in video files that you will be placing on the web. Frame size\u003cbr\u003eof a project is usually equal to the frame size of the final video file but for internet usage,\u003cbr\u003eyou will want to reduce the frame size so that there is less data to transfer when the\u003cbr\u003evideo plays on the internet.\u003cbr\u003eFrame rate is also a factor with your video files in that it helps determine the quality of\u003cbr\u003emotion in the video. When the frame rate is right then the video will flow smoothly and\u003cbr\u003ewhen it is off the video will appear choppy. Frame rate of the project usually should also\u003cbr\u003ebe equal to the frame rate of the final video file but again for internet usage this is also\u003cbr\u003enot the case. Frame rate for web videos should be lower so that it helps with\u003cbr\u003ecompression of the file.\u003cbr\u003eOnce your video is complete and you are ready to place the video on the web, you will\u003cbr\u003eneed to look at the compression. Compression takes a video file and compresses it to a\u003cbr\u003esmaller size to allow it to play on a web page without pulling a lot of bandwidth. The\u003cbr\u003eproblem that some people face with video file compression is finding the right amount of\u003cbr\u003ecompression. If the compression is to low the data rate will be too high which can cause\u003cbr\u003eerrors. If the compression is too high then the date rate will be lowered to far causing\u003cbr\u003ethe picture quality to lousy.\u003cbr\u003eChapter 3 – Web Video File Formats\u003cbr\u003eSeveral formats can be used for web video files. These formats determine the\u003cbr\u003ecompression and the decompression of the video files. They also determine which type\u003cbr\u003eof player that the videos will run in. Players being Windows Media Player, Quick Time,\u003cbr\u003eFlash Media Player and Real Time etcetera. However, some video formats can play\u003cbr\u003ewithin several media players. Web video file formats also use what is known as a codec\u003cbr\u003eto encode the compression and decompression of the video, also a codec can\u003cbr\u003edetermine what player the video is played on.\u003cbr\u003eMPEG (Moving Pictures Expert Group)\u003cbr\u003eMPEG is one of the most popular formats on the World Wide Web. Since MPEG is what\u003cbr\u003eis known as a cross-platform format, it is viewable by all the mainstream web browsers.\u003cbr\u003eSome professionals liken the quality of a web video in MPEG format to that of the\u003cbr\u003equality of VHS tape. The high level of compression that allows the video to be of smaller\u003cbr\u003esize without losing the quality. This makes it easier for viewers to watch the video no\u003cbr\u003ematter what their connection speed is. The benefit to your company is that you will not\u003cbr\u003esuffer a lost sale because the viewer did not want to wait a long time for the video to\u003cbr\u003eload and thus moved on to another website.\u003cbr\u003eMPEG has two file extensions and they are filename.mpg and filename.mpeg.\u003cbr\u003eMicrosoft AVI Video (AVI)\u003cbr\u003eAVI file format offers you minimal compression and is available for the Windows\u003cbr\u003eplatform. There are several Windows applications that can play an AVI video file but the\u003cbr\u003emost common is Windows Media Player. While a video file format is basically a codec,\u003cbr\u003eAVI itself uses different codecs such as Indeo 3.2, MPEG-4V2, Cinepak and several\u003cbr\u003eothers. This makes an AVI file format difficult to run because it requires that your\u003cbr\u003ecustomers or clients have that specific codec installed in their media player. Should a\u003cbr\u003ecustomer or client not have the specific codec that you used when creating your AVI file,\u003cbr\u003ethey will not be able to play your web video within their media player. The way around\u003cbr\u003ethis would be to set your web video up to play directly on the web page. This is usually\u003cbr\u003eonly possible if your web video is embedded in your own web page on your own\u003cbr\u003ewebsite.\u003cbr\u003eFile extension for Microsoft AVI format is filename.avi.\u003cbr\u003eApple Quick Time (MOV)\u003cbr\u003eApple Quick Time is a file format that was developed by Apple and is a widely used\u003cbr\u003eformat on the Internet. Apple Quick Time videos can be what are known as flattened.\u003cbr\u003eThe reason for flattening the videos is so that they can be viewed on both a Macintosh\u003cbr\u003eand a PC. While Apple Quick Time can offer higher quality on the images, the file sizes\u003cbr\u003eare large. This can pose a problem with loading...","brand":"0penny.com","offers":[{"title":"Default Title","offer_id":47079825309936,"sku":"2940014024815","price":0.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014024815_p0.jpg?v=1763599209","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014024815","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
